springboot全局异常处理详解-创新互联

一、单个controller范围的异常处理

package com.xxx.secondboot.web;

import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;

import com.xxx.secondboot.exception.MyExceptionResponse;

import io.swagger.annotations.Api;

@Api("测试controllerAdvice和全局异常处理")
@RestController
@RequestMapping("/advice1")
public class AdviceController {

  @RequestMapping(value = "/test1", method = RequestMethod.GET)
  public String test1() {
    throw new RuntimeException("advice1 - exception1");
  }

  @RequestMapping(value = "/test2", method = RequestMethod.GET)
  public String test2() {
    throw new RuntimeException("advice1 - exception2");
  }

  @ExceptionHandler(RuntimeException.class)
  public MyExceptionResponse exceptionHandler() {
    MyExceptionResponse resp = new MyExceptionResponse();
    resp.setCode(300);
    resp.setMsg("exception-Handler");
    return resp;
  }

}
