說(shuō)明：使用JSR303規(guī)范校驗(yàn)http接口請(qǐng)求參數(shù)
源碼：https://github.com/zccodere/s...

第一章：理論簡(jiǎn)介 1-1 背景介紹

如今互聯(lián)網(wǎng)項(xiàng)目都采用HTTP接口形式進(jìn)行開(kāi)發(fā)。無(wú)論是Web調(diào)用還是智能設(shè)備APP調(diào)用，只要約定好參數(shù)形式和規(guī)則就能夠協(xié)同開(kāi)發(fā)。返回值用得最多的就是JSON形式。服務(wù)端除了保證正常的業(yè)務(wù)功能，還要經(jīng)常對(duì)傳進(jìn)來(lái)的參數(shù)進(jìn)行驗(yàn)證，例如某些參數(shù)不能為空，字符串必須含有可見(jiàn)字符，數(shù)值必須大于0等這樣的要求。

1-2 基礎(chǔ)理論

什么是JSR303規(guī)范

首先JSR 303是Java的標(biāo)準(zhǔn)規(guī)范。
根據(jù)官方文檔的描述：在一個(gè)應(yīng)用的不同層面（例如呈現(xiàn)層到持久層），
驗(yàn)證數(shù)據(jù)是一個(gè)是反復(fù)共同的任務(wù)。
許多時(shí)候相同的驗(yàn)證要在每一個(gè)獨(dú)立的驗(yàn)證框架中出現(xiàn)很多次。
為了提升開(kāi)發(fā)效率，阻止重復(fù)造輪子，于是形成了這樣一套規(guī)范。
該規(guī)范定義了一個(gè)元數(shù)據(jù)模型，默認(rèn)的元數(shù)據(jù)來(lái)源是注解（annotation）。

什么是AOP

是一種編程范式，不是編程語(yǔ)言
解決特定問(wèn)題，不能解決所有問(wèn)題
是OOP的補(bǔ)充，不是替代

JSR303定義的校驗(yàn)類型

空檢查

@Null       驗(yàn)證對(duì)象是否為null
@NotNull    驗(yàn)證對(duì)象是否不為null, 無(wú)法查檢長(zhǎng)度為0的字符串
@NotBlank   檢查約束字符串是不是Null還有被Trim的長(zhǎng)度是否大于0
@NotEmpty   檢查約束元素是否為NULL或者是EMPTY.

Booelan檢查

@AssertTrue     驗(yàn)證 Boolean 對(duì)象是否為 true  
@AssertFalse    驗(yàn)證 Boolean 對(duì)象是否為 false

長(zhǎng)度檢查

@Size(min=, max=) 驗(yàn)證對(duì)象（Array,Collection,Map,String）長(zhǎng)度是否在給定的范圍之內(nèi)  
@Length(min=, max=) Validates that the annotated string is between min and max included.

日期檢查

@Past       驗(yàn)證 Date 和 Calendar 對(duì)象是否在當(dāng)前時(shí)間之前  
@Future     驗(yàn)證 Date 和 Calendar 對(duì)象是否在當(dāng)前時(shí)間之后  
@Pattern    驗(yàn)證 String 對(duì)象是否符合正則表達(dá)式的規(guī)則

數(shù)值檢查，建議使用在Stirng,Integer類型，不建議使用在int類型上，因?yàn)楸韱沃禐椤啊睍r(shí)無(wú)法轉(zhuǎn)換為int，但可以轉(zhuǎn)換為Stirng為"",Integer為null

@Min            驗(yàn)證 Number 和 String 對(duì)象是否大等于指定的值  
@Max            驗(yàn)證 Number 和 String 對(duì)象是否小等于指定的值  
@DecimalMax 被標(biāo)注的值必須不大于約束中指定的最大值. 這個(gè)約束的參數(shù)是一個(gè)通過(guò)BigDecimal定義的最大值的字符串表示.小數(shù)存在精度
@DecimalMin 被標(biāo)注的值必須不小于約束中指定的最小值. 這個(gè)約束的參數(shù)是一個(gè)通過(guò)BigDecimal定義的最小值的字符串表示.小數(shù)存在精度
@Digits     驗(yàn)證 Number 和 String 的構(gòu)成是否合法  
@Digits(integer=,fraction=) 驗(yàn)證字符串是否是符合指定格式的數(shù)字，interger指定整數(shù)精度，fraction指定小數(shù)精度。
@Range(min=, max=) 檢查數(shù)字是否介于min和max之間.
@Range(min=10000,max=50000,message="range.bean.wage")

private BigDecimal wage;

@Valid 遞歸的對(duì)關(guān)聯(lián)對(duì)象進(jìn)行校驗(yàn), 如果關(guān)聯(lián)對(duì)象是個(gè)集合或者數(shù)組,那么對(duì)其中的元素進(jìn)行遞歸校驗(yàn),如果是一個(gè)map,則對(duì)其中的值部分進(jìn)行校驗(yàn).(是否進(jìn)行遞歸驗(yàn)證)
@CreditCardNumber信用卡驗(yàn)證
@Email  驗(yàn)證是否是郵件地址，如果為null,不進(jìn)行驗(yàn)證，算通過(guò)驗(yàn)證。
@ScriptAssert(lang= ,script=, alias=)
@URL(protocol=,host=, port=,regexp=, flags=)
