一、單個controller范圍的異常處理
1 package com.xxx.secondboot.web; 2 3 import org.springframework.web.bind.annotation.ExceptionHandler; 4 import org.springframework.web.bind.annotation.RequestMapping; 5 import org.springframework.web.bind.annotation.RequestMethod; 6 import org.springframework.web.bind.annotation.RestController; 7 8 import com.xxx.secondboot.exception.MyExceptionResponse; 9 10 import io.swagger.annotations.Api; 11 12 @Api("測試controllerAdvice和全局異常處理") 13 @RestController 14 @RequestMapping("/advice1") 15 public class AdviceController { 16 17 @RequestMapping(value = "/test1", method = RequestMethod.GET) 18 public String test1() { 19 throw new RuntimeException("advice1 - exception1"); 20 } 21 22 @RequestMapping(value = "/test2", method = RequestMethod.GET) 23 public String test2() { 24 throw new RuntimeException("advice1 - exception2"); 25 } 26 27 @ExceptionHandler(RuntimeException.class) 28 public MyExceptionResponse exceptionHandler() { 29 MyExceptionResponse resp = new MyExceptionResponse(); 30 resp.setCode(300); 31 resp.setMsg("exception-Handler"); 32 return resp; 33 } 34 35 }
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
1 package com.xxx.secondboot.web; 2 3 import javax.servlet.http.HttpServletResponse; 4 5 import org.springframework.web.bind.annotation.ControllerAdvice; 6 import org.springframework.web.bind.annotation.ExceptionHandler; 7 import org.springframework.web.bind.annotation.ResponseBody; 8 import org.springframework.web.bind.annotation.RestController; 9 10 import com.xxx.secondboot.exception.MyExceptionResponse; 11 import com.xxx.secondboot.exception.MyRuntimeException; 12 13 //@ControllerAdvice(annotations=RestController.class) 14 //@ControllerAdvice(basePackages={"com.xxx","com.ooo"}) 15 @ControllerAdvice 16 public class GlobalExceptionHandler { 17 @ExceptionHandler(RuntimeException.class) 18 // @ExceptionHandler(value={RuntimeException.class,MyRuntimeException.class}) 19 // @ExceptionHandler//處理所有異常 20 @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 21 public MyExceptionResponse exceptionHandler(RuntimeException e, HttpServletResponse response) { 22 MyExceptionResponse resp = new MyExceptionResponse(); 23 resp.setCode(300); 24 resp.setMsg("exception-Handler"); 25 // response.setStatus(600); 26 return resp; 27 } 28 }
說明:
2、controller
1 package com.xxx.secondboot.web; 2 3 import org.springframework.web.bind.annotation.RequestMapping; 4 import org.springframework.web.bind.annotation.RequestMethod; 5 import org.springframework.web.bind.annotation.RestController; 6 7 import io.swagger.annotations.Api; 8 9 @Api("測試controllerAdvice和全局異常處理") 10 @RestController 11 @RequestMapping("/advice1") 12 public class AdviceController { 13 14 @RequestMapping(value = "/test1", method = RequestMethod.GET) 15 public String test1() { 16 throw new RuntimeException("advice1 - exception1"); 17 } 18 19 @RequestMapping(value = "/test2", method = RequestMethod.GET) 20 public String test2() { 21 throw new RuntimeException("advice1 - exception2"); 22 } 23 24 // @ExceptionHandler(RuntimeException.class) 25 // public MyExceptionResponse exceptionHandler() { 26 // MyExceptionResponse resp = new MyExceptionResponse(); 27 // resp.setCode(300); 28 // resp.setMsg("exception-Handler"); 29 // return resp; 30 // } 31 32 }
