java - @RestControllerAdvice 未实例化

问题描述

我希望使用@RestControllerAdvice 和@ExceptionHandler 处理一些内部服务器错误（代码：500），不幸的是，对我来说没有任何效果。

package com.ocx.dlx.globalexception;
@RestControllerAdvice(basePackages  = "com.ocx.dlx.controller")
public class GlobalExceptionHandler extends ResponseEntityExceptionHandler {

    @ExceptionHandler(value = RuntimeException.class)
    public ResponseEntity<InternalErrorResponse> handleInternalServerError(RuntimeException ex, WebRequest request) {
        InternalErrorResponse exceptionResponse =  InternalErrorResponse.builder()
                .code(SecurityConstants.INTERNAL_SERVER_ERROR).msg("internal server exception raised").build();
        return new ResponseEntity<>(exceptionResponse, HttpStatus.INTERNAL_SERVER_ERROR);
    }
}

我的一些控制器在包中com.ocx.dlx.controller，我的应用程序类在com.ocx.dlx包中。

我尝试了 StackOverflow 和其他一些站点中给出的所有可能的解决方案，仍然没有调用 RestControllerAdvice 注释类。

我尝试了以下方法：

  1. 启用WebMvc即@EnableWebMvc
  2. 包装结构
  3. 改变了所有的例外@ExceptionHandler()
  4. mvn clean
  5. 项目清理并开始
  6. 将泛型类型更改为ResponseEntity<Object>
  7. 不扩展ResponseEntityExceptionHandler

你的帮助真的会让我今晚睡个好觉......我挣扎了一天。提前致谢

响应是

解决方案

这就是我解决它的方法，这是我的主类，我通知从包中搜索弹簧组件。

这是扫描包的主要代码@SpringBootApplication(scanBasePackages = "com.ocx.dlx.*")

package com.example.demo;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication(scanBasePackages = "com.ocx.dlx.*")
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}

测试控制器

package com.ocx.dlx.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {

    @GetMapping(path = "/throw-exception")
    public String throwException() {
        throw new RuntimeException("Cannot execute this command");
    }

}

自定义异常处理程序

package com.ocx.dlx.globalexception;

import org.springframework.http.HttpStatus;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.ExceptionHandler;
import org.springframework.web.bind.annotation.RestControllerAdvice;
import org.springframework.web.context.request.WebRequest;
import org.springframework.web.servlet.mvc.method.annotation.ResponseEntityExceptionHandler;

@RestControllerAdvice
public class GlobalExceptionHandler extends ResponseEntityExceptionHandler {

    @ExceptionHandler(value = RuntimeException.class)
    public ResponseEntity<InternalErrorResponse> handleInternalServerError(RuntimeException ex, WebRequest request) {
        InternalErrorResponse exceptionResponse = new InternalErrorResponse(
                HttpStatus.INTERNAL_SERVER_ERROR.value(),
                "custom internal server exception raised");
        return new ResponseEntity<>(exceptionResponse, HttpStatus.INTERNAL_SERVER_ERROR);
    }


    public static class InternalErrorResponse {
        private int code;
        private String msg;

        public InternalErrorResponse(int code, String msg) {
            this.code = code;
            this.msg = msg;
        }

        public int getCode() {
            return code;
        }

        public String getMsg() {
            return msg;
        }
    }
}
