导读:springboot中抛出异常,springboot自带的是springmvc框架,这个就不多说了。 springmvc统一异常解决方法这里要说明的是。只是结合了springboot的使用而已。直接上代码,有效有用的才是ok。 1.定义异常捕获 package com.example.rest.error;import org.spring
springboot中抛出异常,springboot自带的是springmvc框架,这个就不多说了。 springmvc统一异常解决方法这里要说明的是。只是结合了springboot的使用而已。直接上代码,有效有用的才是ok。 1.定义异常捕获 package com.example.rest.error; import org.springframework.http.HttpStatus; import org.springframework.web.bind.annotation.ExceptionHandler; import org.springframework.web.bind.annotation.ResponseStatus; import org.springframework.web.bind.annotation.RestControllerAdvice; import org.springframework.web.servlet.NoHandlerFoundException; import javax.validation.ConstraintViolationException; /** * * @author ming 定义全局异常处理 * @RestControllerAdvice 是@controlleradvice 与@ResponseBody 的组合注解 */ @RestControllerAdvice public class GlobalControllerExceptionHandler { @ExceptionHandler(value = { ConstraintViolationException.class }) @ResponseStatus(HttpStatus.BAD_REQUEST) public ApiErrorResponse constraintViolationException(ConstraintViolationException ex) { return new ApiErrorResponse(500,5001,ex.getMessage()); } @ExceptionHandler(value = { IllegalArgumentException.class }) @ResponseStatus(HttpStatus.BAD_REQUEST) public ApiErrorResponse IllegalArgumentException(IllegalArgumentException ex) { return new ApiErrorResponse(501,5002,ex.getMessage()); } @ExceptionHandler(value = { NoHandlerFoundException.class }) @ResponseStatus(HttpStatus.NOT_FOUND) public ApiErrorResponse noHandlerFoundException(Exception ex) { return new ApiErrorResponse(404,4041,ex.getMessage()); } @ExceptionHandler(value = { Exception.class }) @ResponseStatus(HttpStatus.INTERNAL_SERVER_ERROR) public ApiErrorResponse unknownException(Exception ex) { return new ApiErrorResponse(500,ex.getMessage()); } } 2.定义一个返回对象 package com.example.rest.error; /** * @author ming */ public class ApiErrorResponse { private int status; private int code; private String message; public ApiErrorResponse(int status,int code,String message) { this.status = status; this.code = code; this.message = message; } public int getStatus() { return status; } public int getCode() { return code; } public String getMessage() { return message; } @Override public String toString() { return "ApiErrorResponse{" + "status=" + status + ",code=" + code + ",message=" + message + '}'; } } 3.定义一个启动Application package com.example; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.web.servlet.config.annotation.EnableWebMvc; @SpringBootApplication @EnableWebMvc public class SpringBootExceptionHandlingApplication { public static void main(String[] args) { SpringApplication.run(SpringBootExceptionHandlingApplication.class,args); } } 4.最后一个测试类 package com.example.rest.controller; import org.springframework.http.MediaType; import org.springframework.util.Assert; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; import javax.validation.ConstraintViolationException; import java.util.Collections; /** * @author ming */ @RestController public class TestController { @GetMapping(value = "/test",produces = MediaType.APPLICATION_JSON_VALUE) public void test(Long id) { Assert.notNull(id,"id不能为空!"); throw new ConstraintViolationException("error",Collections.emptySet()); } } 注意application.properties这个文件的配置 spring.mvc.throw-exception-if-no-handler-found=true ok,springboot中解决springmvc异常抛出就可以这样解决了。 以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持编程小技巧。 您可能感兴趣的文章:
