一. 在javaEE项目中经常要判断一些字段的格式是否正确。在以前基本上都是用if(啥啥 啥)else(啥啥啥) 。但是在知道@Validated之后就开始尝试用这个注解了。不但减轻代码量而 且代码更加的易读规整。
二. 下面就以简单例子来说明。
- Controller 层
@PostMapping("student")
@ApiOperation("学生注册")
public @ResponseBody
Map<String, Object> registerStudent(@RequestBody @Validated UserJsonBean user, HttpServletRequest request) throws UnsupportedEncodingException, NoSuchAlgorithmException {Map<String,Object> retMap;retMap=registerService.baseRegister(user,0,request);return retMap;}在要校验对象上加上@Validated注解
2.Bean层
(1)
public class UserJsonBean extends User
(2)
public class User {@Id@Column(name="id",nullable = false)@GeneratedValueprivate Long id;@Email@Column(name = "user_email", nullable = false)private String userEmail;3.测试
（1）传入数据
{"emailCode": 1234,"phoneCode": "1234","picCode": "string","userEmail": "zjut.wujinhuiqq.com","userName": "wujinhui","userPassword": "123456","userPhone": "string"
}（2）测试结果：
{"timestamp": "2018-05-25T10:19:59.898+0000","status": 400,"error": "Bad Request","errors": [{"codes": ["Email.userJsonBean.userEmail","Email.userEmail","Email.java.lang.String","Email"],"arguments": [{"codes": ["userJsonBean.userEmail","userEmail"],"arguments": null,"defaultMessage": "userEmail","code": "userEmail"},[],{"defaultMessage": ".*","arguments": null,"codes": [".*"]}],"defaultMessage": "不是一个合法的电子邮件地址","objectName": "userJsonBean","field": "userEmail","rejectedValue": "zjut.wujinhuiqq.com","bindingFailure": false,"code": "Email"}],"message": "Validation failed for object='userJsonBean'. Error count: 1","path": "/register/student"
}三.@Validated 相关注解
