使用async-validator如何编写Form组件(详细教程)

本篇文章主要介绍了使用 async-validator 编写 Form 组件的方法,现在分享给大家,也给大家做个参考。

前端开发中,表单的校验一个很常见的功能,一些 ui 库例如ant.design 与Element ui 都实现了有校验功能的 Form 组件。async-validator 是一个可以对数据进行异步校验的库,ant.design 与 Element ui 的 Form 组件都使用了 async-validator。本文就简单介绍一下 async-validator 的基本用法以及使用该库实现一个简单的有校验功能的 Form 组件。

1. async-validator 的基本用法async-validator 的功能是校验数据是否合法,并且根据校验规则给出提示信息。

下面演示一下 async-validator 的最基本用法。

import AsyncValidator from 'async-validator'

// 校验规则

const descriptor = {

username: [

{

required: true,

message: '请填写用户名'

},

{

min: 3,

max: 10,

message: '用户名长度为3-10'

}

]

}

// 根据校验规则构造一个 validator

const validator = new AsyncValidator(descriptor)

const data = {

username: 'username'

}

validator.validate(model, (errors, fields) => {

console.log(errors)

})当数据不符合校验规则时,在 validator.validate 的回调函数中,就可以得到相应的错误信息。

当 async-validator 中常见的校验规则无法满足需求时,我们可以编写自定义的校验函数来校验数据。一个简单的校验函数如下。

function validateData (rule, value, callback) {

let err

if (value === 'xxxx') {

err = '不符合规范'

}

callback(err)

}

const descriptor = {

complex: [

{

validator: validateData

}

]

}

const validator = new AsyncValidator(descriptor)async-validator 支持对数据异步校验,所以在编写自定义校验函数时,不管校验是否通过,校验函数中的 callback 都要调用。

2. 编写 Form 组件与 FormItem 组件现在知道了 async-validator 的使用方法,如何将这个库跟要编写的 Form 组件结合起来呢。

实现思路

用一张图描述一下实现思路。

Form 组件

Form 组件应该是一个容器,里面包含不定数量的 FormItem 或者其他元素。可以使用 Vue 内置的slot 组件来代表 Form 里面的内容。

Form 组件还需要知道包含了多少个需要校验的 FormItem 组件。一般情况下,父子组件的通信 是通过在子组件上绑定事件实现的,但是这里使用 slot,无法监听到子组件的事件。这里可以在 Form 组件上通过$on 监听事件,FormItem 挂载或者销毁前触发 Form 组件的自定义事件即可。

按照这个思路,我们先编写 Form 组件。

<template>

<form class="v-form">

<slot></slot>

</form>

</template>

<script>

import AsyncValidator from 'async-validator'

export default {

name: 'v-form',

componentName: 'VForm', // 通过 $options.componentName 来找 form 组件

data () {

return {

fields: [], // field: {prop, el},保存 FormItem 的信息。

formError: {}

}

},

computed: {

formRules () {

const descriptor = {}

this.fields.forEach(({prop}) => {

if (!Array.isArray(this.rules[prop])) {

console.warn(`prop 为 ${prop} 的 FormItem 校验规则不存在或者其值不是数组`)

descriptor[prop] = [{ required: true }]

return

}

descriptor[prop] = this.rules[prop]

})

return descriptor

},

formValues () {

return this.fields.rece((data, {prop}) => {

data[prop] = this.model[prop]

return data

}, {})

}

},

methods: {

validate (callback) {

const validator = new AsyncValidator(this.formRules)

validator.validate(this.formValues, (errors) => {

let formError = {}

if (errors && errors.length) {

errors.forEach(({message, field}) => {

formError[field] = message

})

} else {

formError = {}

}

this.formError = formError

// 让错误信息的顺序与表单组件的顺序相同

const errInfo = []

this.fields.forEach(({prop, el}, index) => {

if (formError[prop]) {

errInfo.push(formError[prop])

}

})

callback(errInfo)

})

}

},

props: {

model: Object,

rules: Object

},

created () {

this.$on('form.addField', (field) => {

if (field) {

this.fields = [...this.fields, field]

}

})

this.$on('form.removeField', (field) => {

if (field) {

this.fields = this.fields.filter(({prop}) => prop !== field.prop)

}

})

}

}

</script>FormItem 组件

FormItem 组件就简单很多,首先要向上找到包含它的 Form 组件。接下来就可以根据 formError 计算出对应的错误信息。

<template>

<p class="form-item">

<label :for="prop" class="form-item-label" v-if="label">

{{ label }}

</label>

<p class="form-item-content">

<slot></slot>

</p>

</p>

</template>

<script>

export default {

name: 'form-item',

computed: {

form () {

let parent = this.$parent

while (parent.$options.componentName !== 'VForm') {

parent = parent.$parent

}

return parent

},

fieldError () {

if (!this.prop) {

return ''

}

const formError = this.form.formError

return formError[this.prop] || ''

}

},

props: {

prop: String,

label: String

}

}

</script>FormItem 在 mounted 与 beforeDestroy 钩子中还需要触发 Form 组件的一些自定义事件。

<script>

export default {

// ...

methods: {

dispatchEvent (eventName, params) {

if (typeof this.form !== 'object' && !this.form.$emit) {

console.error('FormItem必须在Form组件内')

return

}

this.form.$emit(eventName, params)

}

},

mounted () {

if (this.prop) {

this.dispatchEvent('form.addField', {

prop: this.prop,

el: this.$el

})

}

},

beforeDestroy () {

if (this.prop) {

this.dispatchEvent('form.removeField', {

prop: this.prop

})

}

}

}

</script>最后新建一个 index.js 导出编写好的组件。

import VForm from './Form.vue'

import FormItem from './FormItem.vue'

export {

VForm,

FormItem

}3. 使用方式表单的校验函数是在 Form 组件中。通过$ref 可以访问到 Form 组件,调用 validate 函数,从而获取到相应的校验信息。

使用方法如下:

<template>

<v-form :model="formData" :rules="rules" ref="form">

<form-item label="手机号" prop="tel">

<input type="tel" maxlength="11" v-model.trim="formData.tel"/>

</form-item>

<button @click="handleSubmit">保存</button>

</v-form>

</template>

<script>

import { VForm, FormItem } from './common/Form'

export default {

data () {

return {

formData: {

tel: ''

},

rules: {

tel: [

{required: true, message: '您的手机号码未输入'},

{pattern: /^1[34578]d{9}$/, message: '您的手机号码输入错误'}

]

}

}

},

methods: {

handleSubmit () {

this.$refs.form.validate(errs => {

console.log(errs)

})

}

},

components: {

VForm,

FormItem

}

}

</script>完整的代码点击这里。

4. 总结本文简单介绍了一下 async-validator 的用法,并实现了一个有校验功能的 Form 组件。这里的实现的 Form 表单存在着很多的不足:(1) 仅仅是在提交表单时才去校验。(2) FormItem 组件也应该根据校验的结果调整 ui,给出相应的提示。所以,Form 组件更适合在交互较少的移动端使用。

大家可以根据这个实现思路,根据应用场景,编写定制化更高的 Form 组件。

上面是我整理给大家的,希望今后会对大家有帮助。

注册 ValidationProvider

有两种注册方法:第一种可以是直接在组件中使用 ValidationProvider 组件(推荐用法)

第二种方法是直接进行全局注册,这样单个组件中就不需要重复注册,当然实际业务中应该不会经常用到表格校验。

在组件模版中使用 ValidationProvider

增加规则

增加信息

前面长度不符合规则的默认提示显然不够友好。为了自定义提示信息,可以在 extend 函数中增加 message 属性

除了自定义规则,VeeValidate 也自带了很多规则,详细内容可参考 官方文档的详细规则 ,下面例举其中一个规则的使用方法

Dear Ann,

Thank you for your letter. I’m glad you like your school.

I go to school from Monday to Friday. We have four classes in the morning and two classes in the afternoon. We have many things to do after class. On Monday and Thursday afternoon we have sports. On Tuesday afternoon some of us have a singing class and on Wednesday afternoon we practise speaking English. My classmates are very friendly. We learn each other and help each other.

On Saturdays and Sundays I don’t go to school. Very often I go to the parks and have a good time with my family there.

Yours,

Dear Mr. Seaton,

Thank you very much for taking me with you on that splendid outing to London. It was the first time that I had seen the Tower or any of the other famous sights. If I'd gone alone, I couldn't have seen nearly as much, because I wouldn't have known my way about.

The weather was splendid on that day, which I thought was rare. I still remember some people told me that in Britain there was weather and no climate. During the same day, it might snow in the morning, rain at noon, shine in the afternoon and be windy before the night falls. So I think I was lucky.

I think the river trip was the best thing of all. London really came alive for me as we saw it from the Thames ring that wonderful journey down to Greenwich. It was all tremendously exciting - a day that I shall never forget.

Thank you for giving me such a great birthday treat.

Yours sincerely,

Linda Chen

Dear Mr. Wang,

Thank you for taking the time to write your wonderful letter in support of MCEA (Maywood Chinese Ecation Association). Your letter clearly articulates all the major reasons children in Maywood will benefit from studying the Chinese language as part of their elementary school ecation. It provides invaluable support that will help making bilingual Chinese ecation a reality in Maywood public schools.

Although MCEA would like to see Palo Alto public schools implement the first bilingual Chinese kindergarten class in September of 20__, we have learned that the school district must take the time to understand how a new program will affect existing ecational offerings, and to validate community interest. Nevertheless, MCEA, with more than 70 members, will continue to actively promote bilingual Chinese ecation in the Palo Alto public schools and will keep you apprised of the progress we make.

Thanks again for sending a letter in support of MCEA. We' will continue to do all we can to realize this program both for families of Chinese descent and those with a general interest in participating in the growing economic power of China.

Yours sincerely,

George Chen

推荐一款十分好用的客户端表单输入校验插件,JQuery的validate插件:

我们知道表单验证的数据最终都是要提交到服务器上的,那么服务器是不是宁缺毋滥,无论用户输入的表单信息是正确的还是错误的,都不作任何判断,都毫无遗漏地存到服务器上?

答案当然是只需要保留用户输入的正确数据,而用户输入的那一部分错误表单信息,通通过滤掉,而validate插件的存在就是让表单的输入的错误信息数据止步于客户端这一端,到服务器的这条路上它会说此路不通,不会让错误的表单输入数据也上传到服务器上当宝进行保存,避免浪费空间。

比如用户明明输入的是一些乱七八糟的特殊字符,不合法的输入,客户端提交了数据之后,等待服务器来进行检验,进而服务器这边马不停蹄地开始干活,把一个错误信息的反馈给客户端。

这样明知道服务器返回来的是失败结果反馈,还非要往服务器跑一趟,不仅浪费用户的带宽还浪费了用户的等待时间,这是一种十分不好的体验。

所以我们十分有必要让表单输入验证止步于客户端,只有客户端检验通过后,才上传到服务器上,这样服务器拿到的就是正确的表单输入,进而保存起来。

Stick to Success

Almost all people work hard for success, but not all people can success. Many people ask how to make success. I think the answer is persistence. The way to success is full of failure and difficulty. People should never give up when meet them. If you give up, you can't be successful. No matter how hard it is, persistence must be there.

我在学习中是如何克服困难的(How to overe my difficulties in learn)

When it es to difficulties of English study, Different people have diverse opinion, such as hard of hearing, less word, confusion of grammar, even poor writing skills etc. As for me, beside what have mentioned above, I have no enough time and energy to learning, which e to a fulltime work and a lot of housework.

How to solute these problem?I think strong will is key to success. Thus, some measures must be taken as following are.

To begin with, I make good use of all available time. I usually study my English until 11 o'clock at night. Then, I make a record on new words with MP3 so that I can review new words on the way both from home to unit and from unit to home. Furthermore, the most important way is, I always make good notes in the class, and review carefully again and again after the class. Finally, I make some simulated position through the way that translate English position into Chinese then translate it into English and imitate it time and again.

It just as proverb goes “slow and steady wins the race”. Eventually, I have a great progress in my learning English. Certainly, the progress is limited. So I still eager to attain some available advise from teacher and clas *** ates.

8. 坚持的重要性英语作文

We often hear people say, “Never give up.” These can be encouraging words and words of determination. A person who believes in them will keep trying to reach his goal no matter how many times he fails. In my opinion, the quality of determination to succeed is an important one to have. Therefore, I believe that we should never give up.

One reason is that if we give up too easily, we will rarely achieve anything. It is not unusual for us to fail in our first attempt at something new, so we should not feel discouraged and should try again. Besides, if we always give up when we fail, we will not be able to develop new skills and grow as people. Another reason we should never give up is that we can learn from our mistakes only if we make a new effort. If we do not try again, the lesson we have learned is wasted. Finally, we should never give up because as we work to reach our goals, we develop confidence, and this confidence can help us succeed in other areas of our lives. If we never challenge ourselves, we will begin to doubt our abilities.

In short, it is important that we do not give up when working for our goals. Whether we succeed in the end or not, we will learn something, and what we learn will help us to bee better, more confident people. Furthermore, if we give up, we have nn chance of attaining us

一、前言

前3篇文章实际都是为本文做铺垫的,如果以下棋表示,前三篇是普通走棋,本篇是将军!

目前市面上有不少表单验证插件,看似强大,实在糟糕!

总结下,有以下一些问题:

    过多干预
    包括:改变了表单元素UI, 为表单元素绑定过多事件等

    布局等*
    包括:需要特定结构的布局,需要特定的类名或者ID

    学习成本
    包括:N多元作者自定义的属性,或者自定义的特定的数据结构

    可用性

    当JS出现错误的时候而无法正常运作的时候,验证就是聋子的耳朵——摆设,即使在现代浏览器下也是如此。

    面向未来的表单验证

    验证驱动
    验证信息HTML驱动,例如HTML5中required, pattern, multiple等

    验证形式
    非即时响应,submit验证,如Chrome浏览器的处理;或者弱即时响应,如FireFox浏览器仅仅红色外发光。

    验证交互
    浮动形式,尖角指示。

    换言之,所谓面向未来的表单验证,是遵循W3C HTML5规范的表单验证,我们可以从目前领先的浏览器中看到大致雏形。而本文所有展示的html5Validate表单验证插件,就是基于这个未来设计的。

    二、html5Validate概述

    html5Validate插件的验证机制、交互形式甚至形式与Chrome浏览器HTML5表单内置验证走的很近。在使用的时候,就是写写原生的HTML5表单代码。我只想说:走阳光大道和过独木桥的感觉是完全不一样的。

    举个简单例子,一个邮箱验证,HTML5代码表示应该是下面这个样子:

    <input type="email" required>

    好巧的是,使用html5Validate进行表单验证的时候,也是使用上面这段HTML代码!

    类似下面的绑定:

    $("form").html5Validate();

    于是,您在提交表单的时候会(在各个浏览器下)看到这样子的提示:
     

    跟Chrome浏览器下的提示文字近似:
     

    html5Validate支持我所知的HTML5验证相关的东西,如type="email", type="number", type="tel", type="url", step, min, max, required, pattern, multiple等,并有一些本地化扩展,如增加了type="zipcode"邮编等,支持type="hidden"的完整验证(HTML5中是忽略的),支持多type共存,例如type="email|tel", 可以让文本框输入邮箱或者手机号码。

    type="date", type="hour", type="password"等因为不同网站规则不一样,因此,没有放在html5Validate中,不过,您可以很简单地进行扩展,使您的项目支持之,这个后面会介绍(参见 part 9-4)。

    为了满足实际开发需求,额外增加了四个自定义属性值:data-key, data-target, data-min, data-max. 具体何用,下面会详细讲解。

    支持自动的全角转半角。

    注意:type="submit", type="reset", type="file", type="image"以及disabled的表单元素没有验证性可言,因此,下面所说的表单元素,并不包括他们。

    兼容性
    html5Validate通过jQuery1.4+测试,支持正常IE6-IE10浏览器,FireFox, Chrome等现代浏览器。

validateform是基于html5的吗

是的

一、前言

前3篇文章实际都是为本文做铺垫的,如果以下棋表示,前三篇是普通走棋,本篇是将军!

目前市面上有不少表单验证插件,看似强大,实在糟糕!

总结下,有以下一些问题:

    过多干预
    包括:改变了表单元素UI, 为表单元素绑定过多事件等

    布局等*
    包括:需要特定结构的布局,需要特定的类名或者ID

    学习成本
    包括:N多元作者自定义的属性,或者自定义的特定的数据结构

    可用性

    当JS出现错误的时候而无法正常运作的时候,验证就是聋子的耳朵——摆设,即使在现代浏览器下也是如此。

    面向未来的表单验证

    验证驱动
    验证信息HTML驱动,例如HTML5中required, pattern, multiple等

    验证形式
    非即时响应,submit验证,如Chrome浏览器的处理;或者弱即时响应,如FireFox浏览器仅仅红色外发光。

    验证交互
    浮动形式,尖角指示。

    换言之,所谓面向未来的表单验证,是遵循W3C HTML5规范的表单验证,我们可以从目前领先的浏览器中看到大致雏形。而本文所有展示的html5Validate表单验证插件,就是基于这个未来设计的。

3. 如何做一名合格的中学生 英语作文怎么写

您好:How to Be a Good Student

We students are the builders and masters of the country. It is important for us to know how to be a good student.

A good student, I think, should be diligent in his studies. The more he studies, the more he will increase his knowledge. Without enough knowledge, we cannot make great contributions to the modernization of our country.

To take care of one's own body is another important thing for good student to do. Anyone, who hasn't got a strong body, can do nothing for his country, even if he has much knowledge. There was a man, who, when he was student, studied hard but neglected his health. No sooner did he e to serve the co畅绩扳啃殖救帮寻爆默untry than he died of poor health. From this we may see that to have a strong body is really very important for a student.

Lastly, to cultivate one's own virtue is most important. Virtue is the essence of a noble and good character. It will greatly help one to be useful and his country heart and soul. When learned people go astray, they do more harm than good to society. We should draw lessons from this.

4. 这篇英语作文怎么写

你好,很高兴为你解答!

Dear Sir or Madam,

I think that middle school students have too much pressure from school.And I agree that there is no need for them to get so much homework to do.And I think it is unfair for child俯姬碘肯鄢厩碉询冬墨ren to stay up doing their homework late .In addition,I think children should have the enough rights to study and relax because only in this way can make them live happily without any pressure.But they should also pay some attention to spending the time on schoolwork in order to keep their grades at a good level.For example, they should do some homework first and after finishing,they can relax for couple of hours and then continue their homework.Because the more homework they have to do,the more pressure they will have,so it is beneficial for them to relax a little.And these are my suggestions.

Yours truly,Mike

亲爱的先生或女士,

我认为中学学生从学校的压力太大了。我认为,他们不需要太多的作业要做。我认为孩子们熬夜做作业是不公平的。另外,我认为孩子应该和放松,因为只有这样才能让他们没有任何压力,生活快乐学习足够的权利。但是他们也应该注意花时间学习以保持他们的成绩在良好水平。例如,他们应该做一些功课首先完成后,他们可以放松几个小时,然后继续他们的作业。因为他们必须做更多的功课,他们将有更多的压力,所以这对他们是有益的放松了一点。这是我的建议。

你真诚的,麦克

若满意, 请采纳, 谢谢!

7. 怎么写一篇英语作文

首先明确近年来中考作文测试形式和文体要求:

一、测试形式是根据文字、图片、图表、或情景提示,按具体要求进行写作(即材料作文)。

二、文体形式:通常以书信、e-mail、感谢信、日记、通知、便条、请假条、讲稿、发言稿、值日报告、介绍、情景故事描写等。重点是应用文和记叙文。

解题方法和技巧:

一、写前认真审题,理清人、物、事,时间,地点,确定文体。

二、所给要点材料全部用上,视情况围绕要点作适当扩展

三、用你最熟悉的句型,多用简单句,少用复杂句。熟记简单句的五种句型 :一,主语+系动词+表语。二、主语+谓语+其它。

即:人(物)+干(是)+什么(宾语或表语)+其它(时间或地点)

四、确立句中谓语动词的时态及动词的形式。如:I saw a girl eating a banana under the tree.

五、注意句子中词汇、词组、短语、句型的搭配

与使用。如:Now people are busy learning about

the Inter.

六、连词成句,组句成篇。用好过渡词,

如and, but,then ,for example,at first, so ,at last.

七、格式正确。

例:

根据中文大意,写出意思连贯、符合逻辑。不少于80 字的短文。所给英文提示词语供选用。

作为一名中学生,你学习的课程一定很的很多但是学校又有丰富多彩的课外活动,例如:有的同学参加英语角的活动;有的同学喜欢球类、跑步等体育运动;有的同学喜欢音乐、舞蹈、美术;还有的同学参加电脑小组,摄影小组集邮小组等。你最喜欢哪一项课外活动?活动中你做了些什么?说说你的想法和理由。

英文提示词语。I ,a,middle school student , learn, many subject ,after class,take part in ,activity,be interested in ,grow up,important,

be sure(不要写出自己真实的姓名和所在学校)

简析:本作文题为提示作文,其事件就全在于我们的日常的学习生活中,给出部分中文和英文提示。写作时注意:

1、选定自己的兴趣与活动(可适当发挥),用足所给的中英文提示。

2、确定写作所用的时态是一般现在时;“想法”的句子用一般将来时。

3、写作时所用的人称是第一人称“我”来写。

4写作的主要句式是“ *** 什么或我是什么”,“我将来干什么……”,尽可能写简单句,也可考虑用“when,because 或after”简单的状语从句。

8. 英语作文怎么写

英语作文(书面表达)是英语综合能力的集中体现,是词汇语法阅读遣词造句篇章结构逻辑思维等的综合考查.一般有经验的老师只要看一下一个人写几句英语,就能大致判断其英语水平.要想 真正提高英语书面表达能力,非在词汇惯用法搭配和基本语法上下苦功夫.同时通过阅读来积累素材.从汉语作文就可知英语作文有多难.也可得到启示该怎么训练.小学到初中在到高中10 多年,有多少学生能够写出象样的汉语作文?

英语作文怎么写?好在知要求根据某个 情景话题写10 多句话,120词左右,同常要看懂提示,认真审题,1).审文体,要求 写成什么文体?如何开头结尾?是书信?是看图作文?还是根据图表写议论文?各种文体 有大致固定的结构.

2))审要点,特别是动词用哪个?评分 时,是按要点是否全部涉及,表达是否清楚来定 档次的.

要点确定后,重要的是用好 动词,可以在原文旁边或图上标出拟用的动词,最好一步到位,将时态 也带进去,确定全文基本时态 是现在时 还是过去时?直接将该词的形式表出来,省略打 草稿的步骤;

3),将要点扩充成句子,注意前后问的连贯和一致.

4),加 必要的连词,是全文连贯和文理通顺,有的句子前后再 调整合并,写成从句或使用非谓语等其他手段.

5).通读全文,检查是否有错.改正拼写和标点错误.写作文 是一个复杂 的思维过程.一篇 号作文需 反复修改,和进行周密的思维活动,没有必要的词汇,素材积累是无从下手的,多读范文,多练习,才有望 提高,正如游泳骑车等技能只有通过不断练习游 和骑 ,而不是纯理论能奏效的.

首先要搞好阅读。阅读是写作的基础,在阅读方面下的功夫越深,驾驭语言的能力也就越强。所以要写好英语先要读好英语,在语言学习方面狠下苦功,教科书要读透,因为教科书中的文章都是一些很好的范文,文笔流畅,语言规范,精彩的一些课文段落要背诵。再就是要进行大量课外阅读,并记住一些好文章的篇章结构。

加强练词造句训练

其次,要加强练词造句的训练。词句对作文相当于造房的材料,无好材料就造不出好房子。平时在学习阅读时要注意收集积累,把好的词语、短语、句型做好笔记。平时在练习中的错误也要做好记录,再对照正确句子,使地道的英语句子如同条件反射,落笔就对。

了解英语写作格式 还有,要了解英语写作的不同体裁与格式。可以先看一本介绍英语写作入门的书,对英语写作有一个初步的概念,如怎么写议论文,如何提出论据,如何展开,如何确定中心句;又如,英语信的格式,如何根据不同身份写不同结束语等,然后根据不同的体裁进行写作练习。

用英语写日记

要养成记英语日记勤练笔的好习惯。经常用英语记日记,等于天天在练笔,这无疑是提高英语协作的行之有效的好办法。在记日记时,不要总是用简单句,要有意识地用一些好的词组、句型、关联词和复合句等,使文句更优美生动。还有要按照题目或所给情景写文章练笔。写好后对照范文,找出差距,然后再练习,这对提高英语作文也很有帮助,在游泳中学会游泳,只有多练习才能练好。

总之,平时学习语言素材积累多了,体裁格式记住了又经常练习不断提高,到作文下笔时就会得心应手,水到渠成。

      bean 验证框架 hibernate validate

      hibernate工作原理

      原理:

      1.读取并解析配置文件

      2.读取并解析映射信息,创建SessionFactory

      3.打开Sesssion

      4.创建事务Transation

      5.持久化操作

      6.提交事务

      7.关闭Session

      8.关闭SesstionFactory

      为什么要用:

      1. 对JDBC访问数据库的代码做了封装,大大简化了数据访问层繁琐的重复性代码。

      2. Hibernate是一个基于JDBC的主流持久化框架,是一个优秀的ORM实现。他很大程度的简化DAO层的编码工作

      3. hibernate使用Java反射机制,而不是字节码增强程序来实现透明性。

      4. hibernate的性能非常好,因为它是个轻量级框架。映射的灵活性很出色。它支持各种关系数据库,从一对一到多对多的各种复杂关系。

      2. Hibernate是如何延迟加载?

      1. Hibernate2延迟加载实现:a)实体对象 b)集合(Collection)

      2. Hibernate3 提供了属性的延迟加载功能

      当Hibernate在查询数据的时候,数据并没有存在与内存中,当程序真正对数据的操作时,对象才存在与内存中,就实现了延迟加载,他节省了服务器的内存开销,从而提高了服务器的性能。

      3.Hibernate中怎样实现类之间的关系?(如:一对多、多对多的关系)

      类与类之间的关系主要体现在表与表之间的关系进行操作,它们都市对对象进行操作,我们程序中把所有的表与类都映射在一起,它们通过配置文件中的many-to-one、one-to-many、many-to-many、

      4. 说下Hibernate的缓存机制

      1. 内部缓存存在Hibernate中又叫一级缓存,属于应用事物级缓存

      2. 二级缓存:

      a) 应用及缓存

      b) 分布式缓存

      条件:数据不会被第三方修改、数据大小在可接受范围、数据更新频率低、同一数据被系统频繁使用、非 关键数据

      c) 第三方缓存的实现

      5. Hibernate的查询方式

      Sql、Criteria,object comptosition

      Hql:

      1、 属性查询

      2、 参数查询、命名参数查询

      3、 关联查询

      4、 分页查询

      5、 统计函数

      6. 如何优化Hibernate?

      1.使用双向一对多关联,不使用单向一对多

      2.灵活使用单向一对多关联

      3.不用一对一,用多对一取代

      4.配置对象缓存,不使用集合缓存

      5.一对多集合使用Bag,多对多集合使用Set

      6. 继承类使用显式多态

      7. 表字段要少,表关联不要怕多,有二级缓存撑腰

      struts工作原理

      Struts工作机制?为什么要使用Struts?

      工作机制:

      Struts的工作流程:

      在web应用启动时就会加载初始化ActionServlet,ActionServlet从

      struts-config.xml文件中读取配置信息,把它们存放到各种配置对象

      当ActionServlet接收到一个客户请求时,将执行如下流程.

      -(1)检索和用户请求匹配的ActionMapping实例,如果不存在,就返回请求路径无效信息;

      -(2)如果ActionForm实例不存在,就创建一个ActionForm对象,把客户提交的表单数据保存到ActionForm对象中;

      -(3)根据配置信息决定是否需要表单验证.如果需要验证,就调用ActionForm的validate()方法;

      -(4)如果ActionForm的validate()方法返回null或返回一个不包含ActionMessage的ActuibErrors对象, 就表示表单验证成功;

      -(5)ActionServlet根据ActionMapping所包含的映射信息决定将请求转发给哪个Action,如果相应的 Action实例不存在,就先创建这个实例,然后调用Action的execute()方法;

      -(6)Action的execute()方法返回一个ActionForward对象,ActionServlet在把客户请求转发给 ActionForward对象指向的JSP组件;

      -(7)ActionForward对象指向JSP组件生成动态网页,返回给客户;

      为什么要用:

      JSP、Servlet、JavaBean技术的出现给我们构建强大的企业应用系统提供了可能。但用这些技术构建的系统非常的繁乱,所以在此之上,我们需要一个规则、一个把这些技术组织起来的规则,这就是框架,Struts便应运而生。

      基于Struts开发的应用由3类组件构成:控制器组件、模型组件、视图组件

      8. Struts的validate框架是如何验证的?

      在struts配置文件中配置具体的错误提示,再在FormBean中的validate()方法具体调用。

      9. 说下Struts的设计模式

      MVC模式: web应用程序启动时就会加载并初始化ActionServler。用户提交表单时,一个配置好的ActionForm对象被创建,并被填入表单相应的数据,ActionServler根据Struts-config.xml文件配置好的设置决定是否需要表单验证,如果需要就调用ActionForm的 Validate()验证后选择将请求发送到哪个Action,如果Action不存在,ActionServlet会先创建这个对象,然后调用 Action的execute()方法。Execute()从ActionForm对象中获取数据,完成业务逻辑,返回一个ActionForward对象,ActionServlet再把客户请求转发给ActionForward对象指定的jsp组件,ActionForward对象指定的jsp生成动态的网页,返回给客户。

      spring工作原理

      1.spring mvc请所有的请求都提交给DispatcherServlet,它会委托应用系统的其他模块负责负责对请求进行真正的处理工作。

      2.DispatcherServlet查询一个或多个HandlerMapping,找到处理请求的Controller.

      3.DispatcherServlet请请求提交到目标Controller

      4.Controller进行业务逻辑处理后,会返回一个ModelAndView

      5.Dispathcher查询一个或多个ViewResolver视图解析器,找到ModelAndView对象指定的视图对象

      6.视图对象负责渲染返回给客户端。

      为什么用:

      {AOP 让开发人员可以创建非行为性的关注点,称为横切关注点,并将它们插入到应用程序代码中。使用 AOP 后,公共服务 (比如日志、持久性、事务等)就可以分解成方面并应用到域对象上,同时不会增加域对象的对象模型的复杂性。

      IOC 允许创建一个可以构造对象的应用环境,然后向这些对象传递它们的协作对象。正如单词 倒置 所表明的,IOC 就像反 过来的 JNDI。没有使用一堆抽象工厂、服务定位器、单元素(singleton)和直接构造(straight construction),每一个对象都是用其协作对象构造的。因此是由容器管理协作对象(collaborator)。

      Spring即使一个AOP框架,也是一IOC容器。 Spring 最好的地方是它有助于您替换对象。有了 Spring,只要用 JavaBean 属性和配置文件加入依赖性(协作对象)。然后可以很容易地在需要时替换具有类似接口的协作对象。}

      Spring 框架是一个分层架构,由 7 个定义良好的模块组成。Spring 模块构建在核心容器之上,核心容器定义了创建、配置和管理 bean 的方式,如图 1 所示。

      组成 Spring 框架的每个模块(或组件)都可以单独存在,或者与其他一个或多个模块联合实现。每个模块的功能如下:

      ☆ 核心容器:核心容器提供 Spring 框架的基本功能。核心容器的主要组件是 BeanFactory,它是工厂模式的实现。BeanFactory 使用控制反转 (IOC)模式将应用程序的配置和依赖性规范与实际的应用程序代码分开。

      ☆ Spring 上下文:Spring 上下文是一个配置文件,向 Spring 框架提供上下文信息。Spring 上下文包括企业服务,例如 JNDI、EJB、电子邮件、国际化、校验和调度功能。

      ☆ Spring AOP:通过配置管理特性,Spring AOP 模块直接将面向方面的编程功能集成到了 Spring 框架中。所以,可以很容易地使 Spring 框架管理的任何对象支持 AOP。Spring AOP 模块为基于 Spring 的应用程序中的对象提供了事务管理服务。通过使用 Spring AOP,不用依赖 EJB 组件,就可以将声明性事务管理集成到应用程序中。

      ☆ Spring DAO:JDBC DAO 抽象层提供了有意义的异常层次结构,可用该结构来管理异常处理和不同数据库供应商抛出的错误消息。异常层次结构简化了错误处理,并且极大地降低了需要编写的异常代码数量(例如打开和关闭连接)。Spring DAO 的面向 JDBC 的异常遵从通用的 DAO 异常层次结构。

      ☆ Spring ORM:Spring 框架插入了若干个 ORM 框架,从而提供了 ORM 的对象关系工具,其中包括 JDO、Hibernate 和 iBatis SQL Map。所有这些都遵从 Spring 的通用事务和 DAO 异常层次结构。

      ☆ Spring Web 模块:Web 上下文模块建立在应用程序上下文模块之上,为基于 Web 的应用程序提供了上下文。所以,Spring 框架支持与 Jakarta Struts 的集成。Web 模块还简化了处理多部分请求以及将请求参数绑定到域对象的工作。

      ☆ Spring MVC 框架:MVC 框架是一个全功能的构建 Web 应用程序的 MVC 实现。通过策略接口,MVC 框架变成为高度可配置的,MVC 容纳了大量视图技术,其中包括 JSP、Velocity、Tiles、iText 和 POI。

      Spring 框架的功能可以用在任何 J2EE 服务器中,大多数功能也适用于不受管理的环境。Spring 的核心要点是:支持不绑定到特定 J2EE 服务的可重用业务和数据访问对象。毫无疑问,这样的对象可以在不同 J2EE 环境 (Web 或 EJB)、应用程序、测试环境之间重用。

      IOC 和 AOP

      控制反转模式(也称作依赖性介入)的基本概念是:不创建对象,但是描述创建它们的方式。在代码中不直接与对象和服务连接,但在配置文件中描述哪一个组件需要哪一项服务。容器(在 Spring 框架中是 IOC 容器) 负责将这些联系在一起。

      在典型的 IOC 场景中,容器创建了所有对象,并设置必要的属性将它们连接在一起,决定什么时间调用方法。下表列出了 IOC 的一个实现模式。
