这篇文章主要为大家详细介绍了springboot springmvc抛出全局异常的解决方法，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
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, 5002, 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
