java – 警告“[参数]参数：无效的块被忽略”从托管bean发布

WARN [Parameters] Parameters : Invalid chunk ignored

一切进程都很好,但是我想把一些这些警告从我们的日志中删除.是什么导致这个警告,我该如何阻止它发生？

以下是相关代码：

@ManagedBean
@SessionScoped
public class MyController {

  private void doStuff() {
    ...
    URL url = new URL(externalServiceUrl);
    HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    conn.setDoOutput(true);
    conn.setDoInput(true);

    wr = new OutputStreamWriter(conn.getOutputStream());
    wr.write(postData);
    wr.flush();

    InputStream is = conn.getInputStream(); // Warning logged after this line
    ...
  }

}
