本文介绍了在SpringBoot项目中，尽管可以使用Validation、Vo验证和参数验证来定义错误信息，给Vo类添加注解以及在控制器中进行验证，但作者在实战中并不推荐这种方法，并提供了相关步骤。

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 Double 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<ObjectError> 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":"ç¨æ·åçæ³¨åå¿é¡»è¾å¥æ£ç¡®çé®ç®±","objectName":"member","field":"mid","rejectedValue":"xx","bindingFailure":false,"code":"Email"}]
