SpringBoot|自定义业务异常使用

代码定义

package com.example.demo.common;



public class ServiceException extends RuntimeException {

    private static final long seriaVersionUID = 1L;

    private String message;

    @Override
    public String getMessage() {
        return message;
    }

    public void setMessage(String message) {
        this.message = message;
    }


    public ServiceException(final String message) {
        this.message = message;
    }

    public ServiceException(final String message, Throwable th) {
        super(message, th);
        this.message = message;
    }

    public static void throwEx(String message){
        throw new ServiceException(message);
    }

}

使用

    @ApiOperation("登录接口")
    @PostMapping("login")
    public String login(@RequestBody UserDto userDto){
        String result = userService.login(userDto);
        if(userDto.getName().contains("error2")){
            throw new ServiceException("error2",new NullPointerException());
        }
        if(userDto.getName().contains("error")){
            ServiceException.throwEx("用户名中含有error");
        }
        return "成功" + result;
    }

一、postman发送error

 二、postman发送error2
