我正在尝试在Spring MVC应用程序中实现对请求和响应进行日志记录的过滤器。
我使用以下代码:
所以,我按预期记录了我的请求和响应。以下是日志记录:
然而,返回的是空响应。这是来自
有什么想法吗?
谢谢
@Component
public class LoggingFilter extends OncePerRequestFilter {
private static final Logger LOGGER = LoggerFactory.getLogger(LoggingFilter.class);
@Override
protected void doFilterInternal(HttpServletRequest request, HttpServletResponse response, FilterChain filterChain) throws ServletException, IOException {
ContentCachingRequestWrapper requestWrapper = new ContentCachingRequestWrapper(request);
ContentCachingResponseWrapper responseWrapper = new ContentCachingResponseWrapper(response);
LOGGER.debug(REQUEST_MESSAGE_FORMAT, requestWrapper.getRequestURI(), requestWrapper.getMethod(), requestWrapper.getContentType(),
new ServletServerHttpRequest(requestWrapper).getHeaders(), IOUtils.toString(requestWrapper.getInputStream(), UTF_8));
filterChain.doFilter(requestWrapper, responseWrapper);
LOGGER.debug(RESPONSE_MESSAGE_FORMAT, responseWrapper.getStatus(), responseWrapper.getContentType(),
new ServletServerHttpResponse(responseWrapper).getHeaders(), IOUtils.toString(responseWrapper.getContentInputStream(), UTF_8));
}
}
所以,我按预期记录了我的请求和响应。以下是日志记录:
