Question

我在某些请求中收到以下异常。它很少发生在一周一次或两次。任何想法可能导致这个或任何建议我应该在哪里调试这个。

Dropwizard版本：1.1.4 jetty-server版本：2.25.1

错误发生在下面的代码中：request.bufferEntity（）

private String getBody(ContainerRequestContext requestContext) {
        if (requestContext instanceof ContainerRequest) {
            ContainerRequest request = (ContainerRequest) requestContext;
            // calling bufferEntity(), without this the entity is marked as closed and causes IllegalStateExceptions
            // on any subsequent read attempt
            request.bufferEntity();
            return request.readEntity(String.class);
        } else {
            // this should never happen as we are using jersey as the jax-rs implementation engine
            throw new RuntimeException("ContainerRequestContext is not an instance of jersey ContainerRequest");
        }
    }

此问题在1.3.8中仍然存在，并且是open issue。

好吧。似乎有一种解决方法。您可以创建一个过滤器类来过滤异常并检查Eof。这是针对我的情况的一种具体技巧。但是，您明白了。我已经对此进行了测试，并且可以正常工作。这是过滤器代码段。


  @Override
  public void doFilter(
      final ServletRequest request,
      final ServletResponse response,
      final FilterChain chain)
      throws IOException, ServletException {
    try {
      chain.doFilter(request, response);
    } catch (ServletException e) {
      if (isEarlyEofException(e)) {
        log.debug("EOF Exception encountered - client disconnected during stream processing.", e);

        if (response instanceof HttpServletResponse) {
          ((HttpServletResponse) response).setStatus(HttpServletResponse.SC_BAD_REQUEST);
        }
      } else {
        throw e;
      }
    }
  }

  private boolean isEarlyEofException(final ServletException e) {
    return e.getCause() instanceof ProcessingException
        && e.getCause().getCause() instanceof EofException
        && e.getCause().getCause().getMessage().equals(EARLY_EOF_MSG);
  }

然后应用过滤器。

  private void addEarlyEofExceptionFilter(final Environment environment) {
    final FilterRegistration.Dynamic filter =
        environment.servlets().addFilter("EarlyEofExceptionFilter", EarlyEofExceptionFilter.class);

    filter.addMappingForUrlPatterns(EnumSet.allOf(DispatcherType.class), true, "/*");
  }
