一、單個controller范圍的異常處理
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("測試controllerAdvice和全局異常處理")
@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;
}
}
說明：
二、全部controller范圍內起作用的異常處理（全局異常處理）
1、全局異常處理類
package com.xxx.secondboot.web;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.bind.annotation.ControllerAdvice;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import com.xxx.secondboot.exception.MyExceptionResponse;
import com.xxx.secondboot.exception.MyRuntimeException;
//@ControllerAdvice(annotations=RestController.class)
//@ControllerAdvice(basePackages={"com.xxx","com.ooo"})
@ControllerAdvice
public class GlobalExceptionHandler {
@ExceptionHandler(RuntimeException.class)
// @ExceptionHandler(value={RuntimeException.class,MyRuntimeException.class})
// @ExceptionHandler//處理所有異常
@ResponseBody //在返回自定義相應類的情況下必須有，這是@ControllerAdvice注解的規定
public MyExceptionResponse exceptionHandler(RuntimeException e, HttpServletResponse response) {
MyExceptionResponse resp = new MyExceptionResponse();
resp.setCode(300);
resp.setMsg("exception-Handler");
// response.setStatus(600);
return resp;
}
}
說明：
2、controller
package com.xxx.secondboot.web;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import io.swagger.annotations.Api;
@Api("測試controllerAdvice和全局異常處理")
@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;
// }
}
