    说明：使用JSR303规范校验http接口请求参数
    源码：https://github.com/zccodere/s...

    第一章：理论简介

    1-1 背景介绍

    如今互联网项目都采用HTTP接口形式进行开发。无论是Web调用还是智能设备APP调用，只要约定好参数形式和规则就能够协同开发。返回值用得最多的就是JSON形式。服务端除了保证正常的业务功能，还要经常对传进来的参数进行验证，例如某些参数不能为空，字符串必须含有可见字符，数值必须大于0等这样的要求。

    1-2 基础理论

    什么是JSR303规范

    首先JSR 303是Java的标准规范。
根据官方文档的描述：在一个应用的不同层面（例如呈现层到持久层），
验证数据是一个是反复共同的任务。
许多时候相同的验证要在每一个独立的验证框架中出现很多次。
为了提升开发效率，阻止重复造轮子，于是形成了这样一套规范。
该规范定义了一个元数据模型，默认的元数据来源是注解（annotation）。

    什么是AOP

    是一种编程范式，不是编程语言
解决特定问题，不能解决所有问题
是OOP的补充，不是替代

    JSR303定义的校验类型

    空检查

    @Null       验证对象是否为null
@NotNull    验证对象是否不为null, 无法查检长度为0的字符串
@NotBlank   检查约束字符串是不是Null还有被Trim的长度是否大于0
@NotEmpty   检查约束元素是否为NULL或者是EMPTY.

    Booelan检查

    @AssertTrue     验证 Boolean 对象是否为 true  
@AssertFalse    验证 Boolean 对象是否为 false

    长度检查

    @Size(min=, max=) 验证对象（Array,Collection,Map,String）长度是否在给定的范围之内  
@Length(min=, max=) Validates that the annotated string is between min and max included.

    日期检查

    @Past       验证 Date 和 Calendar 对象是否在当前时间之前  
@Future     验证 Date 和 Calendar 对象是否在当前时间之后  
@Pattern    验证 String 对象是否符合正则表达式的规则

    数值检查，建议使用在Stirng,Integer类型，不建议使用在int类型上，因为表单值为“”时无法转换为int，但可以转换为Stirng为"",Integer为null

    @Min            验证 Number 和 String 对象是否大等于指定的值  
@Max            验证 Number 和 String 对象是否小等于指定的值  
@DecimalMax 被标注的值必须不大于约束中指定的最大值. 这个约束的参数是一个通过BigDecimal定义的最大值的字符串表示.小数存在精度
@DecimalMin 被标注的值必须不小于约束中指定的最小值. 这个约束的参数是一个通过BigDecimal定义的最小值的字符串表示.小数存在精度
@Digits     验证 Number 和 String 的构成是否合法  
@Digits(integer=,fraction=) 验证字符串是否是符合指定格式的数字，interger指定整数精度，fraction指定小数精度。
@Range(min=, max=) 检查数字是否介于min和max之间.
@Range(min=10000,max=50000,message="range.bean.wage")

    private BigDecimal wage;

    @Valid 递归的对关联对象进行校验, 如果关联对象是个集合或者数组,那么对其中的元素进行递归校验,如果是一个map,则对其中的值部分进行校验.(是否进行递归验证)
@CreditCardNumber信用卡验证
@Email  验证是否是邮件地址，如果为null,不进行验证，算通过验证。
@ScriptAssert(lang= ,script=, alias=)
@URL(protocol=,host=, port=,regexp=, flags=)

hibernate-validator-4.2.0.Final.jar是对上述接口的实现

    Gradle坐标

compile ('org.hibernate:hibernate-validator:5.4.1.Final')

    第二章：简单实战

    2-1 基于SpringMVC

    工程创建

    创建名为valid-mvc的gradle工程build.gradle如下

    apply plugin: 'war'
apply plugin: 'java'
apply plugin: 'eclipse'

[compileJava, javadoc, compileTestJava]*.options*.encoding = 'UTF-8'

ext {
    springVersion = "4.3.8.RELEASE"
}  

repositories {
    mavenLocal()
    maven{ url "http://maven.aliyun.com/nexus/content/groups/public" }
    mavenCentral()
}

dependencies {

    // Spring框架
    compile ("org.springframework:spring-core:${springVersion}")
    compile ("org.springframework:spring-beans:${springVersion}")
    compile ("org.springframework:spring-context:${springVersion}")
    compile ("org.springframework:spring-web:${springVersion}")
    compile ("org.springframework:spring-webmvc:${springVersion}")
    compile ("org.springframework:spring-aop:${springVersion}")    
    compile ("org.springframework:spring-aspects:${springVersion}")    
    
    compile ('javax.servlet:javax.servlet-api:3.0.1')
    compile ("com.alibaba:fastjson:1.2.20")
    
    // JSR303数据校验
    compile ('javax.validation:validation-api:1.1.0.Final')
    compile ('org.hibernate:hibernate-validator:5.4.1.Final')
}

 */
public class WebInitializer implements  WebApplicationInitializer  {

    @Override
    public void onStartup(ServletContext servletContext) throws ServletException {
      
        // 新建WebApplication，注册配置类，并将其和当前servletContext关联。
        AnnotationConfigWebApplicationContext context = new AnnotationConfigWebApplicationContext();
        context.register(SpringConfig.class);
        context.setServletContext(servletContext);
        
        // 注册SpringMvc的DispatcherServlet。
        Dynamic servlet = servletContext.addServlet("dispatcher", new DispatcherServlet(context));
        servlet.addMapping("/");
        servlet.setLoadOnStartup(1);

        FilterRegistration.Dynamic encodingFilter = servletContext.addFilter("encoding", new CharacterEncodingFilter());
        EnumSet<DispatcherType> dispatcherTypes = EnumSet.allOf(DispatcherType.class);
        dispatcherTypes.add(DispatcherType.REQUEST);
        dispatcherTypes.add(DispatcherType.FORWARD);

public class ReqBaseVO implements Serializable{
    
    private static final long serialVersionUID = 7023512707419434863L;

    private String transId;
    
    private String systemCall;
    
    @Override
    public String toString() {
        return "ReqBaseVO [transId=" + transId + ", systemCall=" + systemCall + "]";
    }

    public String getTransId() {
        return transId;
    }

    public void setTransId(String transId) {
        this.transId = transId;
    }

    public String getSystemCall() {
        return systemCall;
    }

    public void setSystemCall(String systemCall) {
        this.systemCall = systemCall;
    }

}

    5.编写RspBaseVO类

    package com.zccoder.valid.boot.vo;

import java.io.Serializable;

public class RspBaseVO implements Serializable{
    
    private static final long serialVersionUID = 7023512707419434863L;

    private String respCode;
    
    private String respDesc;

    @Override
    public String toString() {
        return "RspBaseVO [respCode=" + respCode + ", respDesc=" + respDesc + "]";
    }
    
    public void setEnRespStatus(EnRespStatus enRespStatus){
        this.respCode = enRespStatus.getRespCode();
        this.respDesc = enRespStatus.getRespDesc();
    }
    
    public String getRespCode() {
        return respCode;
    }

    public void setRespCode(String respCode) {
        this.respCode = respCode;
    }

    public String getRespDesc() {
        return respDesc;
    }

    public void setRespDesc(String respDesc) {
        this.respDesc = respDesc;
    }
    
    
    
}

    6.编写StoreReqVO类

    package com.zccoder.valid.boot.vo;

import javax.validation.constraints.Size;

import org.hibernate.validator.constraints.NotBlank;

public class StoreReqVO extends ReqBaseVO{

    private static final long serialVersionUID = -342969591273353836L;
    
    @Size(min=2,max=5)
    @NotBlank
    private String name;
    
    @NotBlank
    private String desc;

    @NotBlank
    private String code;
    
    @Override
    public String toString() {
        return "StoreVO [name=" + name + ", desc=" + desc + ", code=" + code + "]";
    }
    
    public String getCode() {
        return code;
    }

    public void setCode(String code) {
        this.code = code;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getDesc() {
        return desc;
    }

    public void setDesc(String desc) {
        this.desc = desc;
    }
    
    
}

    7.编写StoreRspVO类

    package com.zccoder.valid.boot.vo;

public class StoreRspVO extends RspBaseVO{

    private static final long serialVersionUID = -342969591273353836L;
    
    private String id;

    @Override
    public String toString() {
        return "StoreRspVO [id=" + id + "]";
    }

    public String getId() {
        return id;
    }

    public void setId(String id) {
        this.id = id;
    }
    
    
    
}

    8.编写StoreRest类

    package com.zccoder.valid.boot.rest;

import javax.validation.Valid;

import org.springframework.validation.BindingResult;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.zccoder.valid.boot.vo.EnRespStatus;
import com.zccoder.valid.boot.vo.StoreReqVO;
import com.zccoder.valid.boot.vo.StoreRspVO;

@RestController
@RequestMapping("/store")
public class StoreRest {
    
    @PostMapping("/create")
    public StoreRspVO create(@Valid StoreReqVO reqVO,BindingResult result){
        StoreRspVO rspVO = new StoreRspVO();
        
        System.out.println("注册成功："+String.valueOf(reqVO.toString()));
        
        rspVO.setId(String.valueOf(System.currentTimeMillis()));
        rspVO.setEnRespStatus(EnRespStatus.SUCCESS);
        
        return rspVO;
    }
}

    进行验证

    启动项目，并使用Postman测试效果如下
