使用 @ControllerAdvice 作为另一个项目的依赖项

Question

我提出一个共同的项目聆听异常和使用@ControllerAdvice与@ExceptionHandler

@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主要的方法来作为依赖添加到我的另一个项目中。我的pom.xml

在将其依赖项添加@ComponentScan到另一个项目之后，但它不能作为响应自定义错误的异常处理工作。我很感激任何帮助。

Answer 1

我发现这与使用无关，@ComponentScan并且使用@Import它会工作得很好。但如果有人有更好的解决方案或一些指导方针，我将不胜感激。
