错误500 HttpURLConnection，但在localhost中可以

Question

我试图用下面的HttpURLConnection调用在JAVA中实现的终结点。 如果我将路径作为我的应用程序在localhost中运行，则一切正常。 但是，当此应用程序发布到服务器（Oracle Weblogic）中时，出现错误：

java.io.IOException：服务器返回HTTP响应代码：URL的500：sun.net.www.protocol.http.HttpURLConnection.getInputStream0（HttpURLConnection.java:1894）的路径，位于sun.net.www.protocol.http.HttpURLConnection处.getInputStream（HttpURLConnection.java:1492）

在带有**的行的下面的块中引发此错误

        try {
            URL url = new URL(path);
            HttpURLConnection conn = (HttpURLConnection) url.openConnection();
            conn.setRequestProperty("Content-Type", "application/json; charset=UTF-8");
            conn.setConnectTimeout(10000);
            conn.setReadTimeout(10000);
            conn.setRequestProperty("Accept", "*/*");
            conn.setRequestProperty("Accept-Encoding", "gzip, deflate");
            conn.setRequestProperty("User-Agent", "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/41.0.2228.0 Safari/537.36");
            conn.setRequestProperty("Content-Language", "en-US");
            conn.setUseCaches(false);
            conn.setDoOutput(true);
            conn.setDoInput(true);
            conn.setRequestMethod("POST");
            conn.setRequestProperty("Connection", "close");
            OutputStream os = conn.getOutputStream();
            os.write(new Gson().toJson(debtAccountList).getBytes("UTF-8"));
            os.flush();
            ***InputStream in = new BufferedInputStream(conn.getInputStream());***

            System.out.println(in.toString());
            in.close();
            os.close();
            conn.disconnect();
        }

是什么使它在localhost而不在已部署的应用程序中起作用？
