连接关闭，检测到 EOF

Question

我想 post 一些 json 数据从启用 ADFS SSO 的 weblogic 服务器到 https url（码头服务器），但我收到以下异常

    java.io.IOException: Connection closed, EOF detected
    at weblogic.socket.JSSEFilterImpl.handleUnwrapResults(JSSEFilterImpl.java:637)
    at weblogic.socket.JSSEFilterImpl.unwrapAndHandleResults(JSSEFilterImpl.java:515)

    at weblogic.net.http.HttpURLConnection.getInputStream(HttpURLConnection.java:433)
    at weblogic.net.http.SOAPHttpsURLConnection.getInputStream(SOAPHttpsURLConnection.java:37)

下面是片段

        URL urlObject = new URL(url);
        HttpURLConnection httpConnection = (HttpURLConnection) urlObject.openConnection();
        httpConnection.setRequestMethod("POST");
        httpConnection.setDoOutput(true);
        httpConnection.setDoInput(true); 
        httpConnection.addRequestProperty("Content-Type", "application/xml");
        OutputStreamWriter writer = new OutputStreamWriter(httpConnection.getOutputStream());
        writer.write(paramJSON.toString());
        writer.flush();

        String line;
        StringBuffer buffer = new StringBuffer();
        BufferedReader reader = new BufferedReader(new InputStreamReader(httpConnection.getInputStream()));
        while ((line = reader.readLine()) != null) 
        {
            buffer.append(line);
        }

        writer.close();
        reader.close();
        int status = httpConnection.getResponseCode();
        httpConnection.disconnect();

这适用于两个 http url，即未启用 SSL

Answer 1

如果我们使用Weblogic服务器，我们必须定义：

set JAVA_OPTIONS=%JAVA_OPTIONS% -DUseSunHttpHandler=true

...在服务器域内的 class 路径中。

这将告诉 weblogic 服务器使用 Sun Http Handlers 而不是安装它自己的。
