Question

我制作了一个用于监听 Exception 的通用项目，并将@ControllerAdvice与@ExceptionHandler

结合使用

@ControllerAdvice(annotations = RestController.class)
public class RestResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {

     @ExceptionHandler({Exception.class})
     @ResponseStatus(value = HttpStatus.NOT_FOUND)
     @ResponseBody
     public ResponseEntity<ErrorResponse> notFound(Exception ex) {
         return new ResponseEntity<>(
            new ErrorResponse(ex.getMessage(), 404, "My Custom Message"), HttpStatus.NOT_FOUND);
     }
}

没有任何@SpringBootApplication和主要方法添加为依赖关系到我的另一个项目。我的pom.xml

将其依赖项和@ComponentScan添加到另一个项目后，但不能作为响应自定义错误的异常处理。感谢您的帮助。

Answer 1

我发现这与使用@ComponentScan无关，而与使用@Import一样，它可以很好地工作。但是如果有人有更好的解决方案或指导方针，我将不胜感激。

使用@ControllerAdvice作为另一个项目的依赖项
