Question

在application.properties中

logging.level.org.springframework.web.filter.CommonsRequestLoggingFilter=DEBUG,stdout
log4j.logger.httpclient.wire=DEBUG,stdout
management.endpoints.web.exposure.include=*
management.endpoint.beans.cache.time-to-live=10s
server.tomcat.accesslog.enabled = true
log4j.logger.org.springframework.web.servlet.mvc.method.annotation.ServletInvocableHandlerMethod=DEBUG,stdout
logging.level.org.springframework.web=DEBUG,stdout

在这里

CommonsRequestLoggingFilter

记录其他请求，但不记录400。为什么？我该如何普遍处理？我对Spring Boot相当陌生，还无法实现restcontrolleradvice

控制器：

@CrossOrigin("*")
@RestController
public class DataController {

@RequestMapping(value = "/abc/track/{type}", method = RequestMethod.GET)

    public void DummFunc(                            
          @RequestParam(value="subs", required = false) String sub,
,  HttpServletResponse response) {}
// @ResponseStatus(HttpStatus.BAD_REQUEST)


@ExceptionHandler(Throwable.class)
    public void handle(HttpMessageNotReadableException e) {
        System.out.println("EXCEPTION HAPPENED");
        System.out.println(e);
    }


}

Answer 1

您可以在控制器中添加以下代码-

@ExceptionHandler
@ResponseStatus(HttpStatus.BAD_REQUEST)
public void handle(HttpMessageNotReadableException e) {
    logger.warn("Returning HTTP 400 Bad Request", e);
}

如果您在@ControllerAdvice级别添加class，将可以全局访问。
不要忘记将类保留在可以由Spring boot扫描的包中

Answer 2

您可以轻松实现ControllerAdvice并处理异常，这里是示例代码：

 @ControllerAdvice
    @RestController
    public class CustomizedResponseEntityExceptionHandler extends ResponseEntityExceptionHandler {

      @ExceptionHandler(Exception.class)
      public final ResponseEntity<ExceptionResponse> handleAllExceptions(Exception ex, WebRequest request) {
             ExceptionResponse exceptionResponse = new ExceptionResponse(new Date(), ex.getMessage(),
        request.getDescription(false));
            // doSomthing 
        return new ResponseEntity<>(exceptionResponse, HttpStatus.INTERNAL_SERVER_ERROR);
      }

这是我的ExceptionResponse类：

public class ExceptionResponse {
  private Date timestamp;
  private String message;
  private String details;

  public ExceptionResponse(Date timestamp, String message, String details) {
    super();
    this.timestamp = timestamp;
    this.message = message;
    this.details = details;
  }

  public Date getTimestamp() {
    return timestamp;
  }

  public String getMessage() {
    return message;
  }

  public String getDetails() {
    return details;
  }

}

虽然404和其他工具确实没有在Spring Boot中记录HTTP 400错误
