我想通过Spring过滤器或方面记录超文本传输协议请求中的请求参数。我尝试了不同的方法，但请求参数为空或未调用方法。我使用的是POSTMAN，它是一个POST请求。

http://localhost:8080/available data

请求正文示例：

{“keyUserAgent”：“CFNetwork/1209 Darwin/20.2.0”，“locale”：“en_US”，“eid”：“8904977033”，“sessionId”：“VGA-G2020201030-776878787-1AD5-11EB-895C-H78789GJJH”}

方法1：这里调用了request（）之前的“@Override”方法，但没有调用我创建的重载方法（我添加了@RequestBody以根据其他解决方案获取正文）。

@Component
public class CustomLoggingFilter extends AbstractRequestLoggingFilter {
      
            protected void beforeRequest(HttpServletRequest request, String message,@RequestBody RequestDTO requestBody) {
            requestBody.getKeyUserAgent();
            requestBody.getEid();
            System.out.println("Eid: "+requestBody.getEid());
            System.out.println("getKeyUserAgent: "+requestBody.getKeyUserAgent());
            
        }  
        
    }

方法2:这里它是空的

@Aspect
@Component
@Order(1)
public class LogAspect {

    private final static Logger logger = LoggerFactory.getLogger(LoggerAspect.class);
      @Around("allControllerMethods() && args(..,@annotation(org.springframework...RequestBody) requestBody) ")
      public Object controllerEvents(ProceedingJoinPoint jp, Object requestBody) throws Throwable {
            
          ServletRequestAttributes attributes = (ServletRequestAttributes) RequestContextHolder.getRequestAttributes();
             HttpServletRequest request = attributes.getRequest();
             MethodSignature signature = (MethodSignature) jp.getSignature();
              Method method = signature.getMethod();
              Object resObject = jp.proceed();
              Object sessionId = attributes.getSessionId()
              if (requestBody != null) {
                  String keyUserAgent = request.getParameter("keyUserAgent");
                  System.out.println("keyUserAgent : " + keyUserAgent);
                  
                }
              
          return resObject;
      }
