Spring4下validation数据校验无效(maven)的解决

Spring4下validation数据校验无效(maven)的解决

SpringMVC4使用数据校验的时候需要使用hibernate-validator的包

第一步添加依赖

javax.validation

validation-api

2.0.0.Final

org.hibernate

hibernate-validator

5.4.1.Final

第二步添加校验注解

package com.demo.model;

/*

* spring4 用hibernate中的validation

*

* */

import org.hibernate.validator.constraints.Email;

import org.hibernate.validator.constraints.NotBlank;

import javax.validation.constraints.Size;

public class User {

private String username;

private String password;

private String nickname;

private String email;

public User(){

}

public User(String username, String password, String nickname, String email) {

this.username = username;

this.password =CdhNGfVVT password;

this.nickname = nickname;

this.email = email;

}

@NotBlank(message = "用户名不能为空")

public String getUsername() {

return username;

}

public void setUsername(String username) {

this.username = username;

}

@Size(min = 6,max = 20,message = "密码为6-20位")

public String getPassword() {

return password;

}

public void setPassword(String password) {

this.password = password;

}

public String getNickname() {

return nickname;

}

public void setNickname(String nickname) {

this.nickname = nickname;

}

@Email(message = "请输入合法的邮箱")

public String getEmail() {

return email;

}

public void setEmail(String email) {

this.email = email;

}

}

第三步在控制器中对指定参数进行校验注解

注:BindingResult 必须紧跟在@Validate

//@Validated指定验证对象 BindingResult紧跟Validated

@RequestMapping(value="/add",method = RequestMethod.POST)

public String add(@Validated User user, BindingResult br){

System.out.println(br);

System.out.println(br.getErrorCount());

if(br.hasErrors())

return "user/add";

users.put(user.getUsername(),user);

return "redirect:/user/users";

}

注：这个配置也会影响到校验是否生效

SpringBoot-----数据验证validation(实战中,不推荐使用)

1、定义错误信息

在resources/下创建名称为ValidationMessages.properties

member.mid.notnull.error=用户名不允许为空

member.mid.email.error=用户名的注册必须输入正确的邮箱

member.mid.length.error=用户名的格式错误

2、给Vo类添加注解

package com.zemel.micorboot.vo;

import java.io.Serializable;

import java.util.Date;

import javax.validation.constraints.Email;

import javax.validation.constraints.NotNull;

import org.hibernate.validator.constraints.Length;

public class Member implements Serializable{

/**

*

*/

private static final long serialVersionUID = 1L;

@NotNull(message="{member.mid.notnull.error}")

@Email(message="{member.mid.email.error}")

@Length(min=6,message="{member.mid.length.error}")

private String mid;

private Integer age;

private Double salary;

private Date birthday;

public String getMid() {

return mid;

}

public void setMid(String mid) {

this.mid = mid;

}

public Integer getAge() {

return age;

}

public void setAge(Integer age) {

this.age = age;

}

public DouCdhNGfVVTble getSalary() {

return salary;

}

public void setSalary(Double salary) {

this.salary = salary;

}

public Date getBirthday() {

return birthday;

}

public void setBirthday(Date birthday) {

this.birthday = birthday;

}

}

3、控制添加验证

@Valid Member vo, BindingResult result

package com.zemel.micorboot.controller;

import java.util.List;

import javax.validation.Valid;

import org.springframework.stereotype.Controller;

import org.springframework.validation.BindingResult;

import org.springframework.validation.ObjectError;

import org.springframework.web.bind.annotation.GetMapping;

import org.springframework.web.bind.annotation.ResponseBody;

import com.zemel.micorboot.base.AbstractBaseController;

import com.zemel.micorboot.vo.Member;

@Controller

public class MemberController extends AbstractBaseController {

@GetMapping("/addPre")

public String addPre(){

return "message/member_add";

}

@GetMapping("/add")

@ResponseBody

public Object add(@Valid Member vo, BindingResult result){

System.out.println("【ADD方法】"+result.hasErrors());

if(result.hasErrors()){

List list = result.getAllErrors();

list.forEach(oe -> {

});

return result.getAllErrors();

}

return vo;

}

}

4、访问结果

[{"codes":["Email.member.mid","Email.mid","Email.java.lang.String","Email"],"arguments":[{"codes":["member.mid","mid"],"arguments":null,"defaultMessage":"mid","code":"mid"},[],{"defaultMessage":".*","arguments":null,"codes":[".*"]}],"defaultMessage":"çæåçæ³åå¿¡»¾å¥æ­£ç¡®ç®ç®","objectName":"member","field":"mid","rejectedValue":"xx","bindingFailure":false,"code":"Email"}]
