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; } }
说明:
二、全部controller范围内起作用的异常处理(全局异常处理)
1、全局异常处理类
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//处理所有异常 @ResponseBody //在返回自定义相应类的情况下必须有,这是@ControllerAdvice注解的规定 public MyExceptionResponse exceptionHandler(RuntimeException e, HttpServletResponse response) { MyExceptionResponse resp = new MyExceptionResponse(); resp.setCode(300); resp.setMsg("exception-Handler"); // response.setStatus(600); return resp; } }
说明:
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("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; // } }
