Mule ESB HTTPS INBOUND ENDPOINT CONNECTION FAILURE

我目前正在使用Mule Studio CE 1.3.2作为开发环境的一部分。我试图为测试目的设置一个基本流程，其中包含一个HTTPS入站端点，目的是从运行基于JSSE的客户端的远程机器上发布一些数据。所用流程的实际位如下所示：

现在尝试从java客户端连接时，其代码（使用已弃用的软件包授予它，但仅用作快速测试）是：

`import java.io.*;
import java.net.MalformedURLException;
import java.net.URL;
import java.security.Security;
import com.sun.net.ssl.HostnameVerifier;
import com.sun.net.ssl.HttpsURLConnection;


public class HTTPSClient {

    private HttpsURLConnection urlConnection=null;

    private static String host_address="192.168.178.47";

    private static int ssl_port=8080;

    public static void setHost_address(String host_address) {
        HTTPSClient.host_address = host_address;
    }

    public static String getHost_address() {
        return host_address;
    }

    public static void setSsl_port(int ssl_port) {
        HTTPSClient.ssl_port = ssl_port;
    }

    public static int getSsl_port() {
        return ssl_port;
    }

    static{

        Security.addProvider(new com.sun.net.ssl.internal.ssl.Provider());

        System.setProperty("java.protocol.handler.pkgs","com.sun.net.ssl.internal.www.protocol");

        System.setProperty("javax.net.ssl.keyStore", "C:/Users/vangelis/client.jks");

        System.setProperty("javax.net.ssl.keyStorePassword", "xxxx");

        System.setProperty("javax.net.ssl.trustStore", "C:/Users/vangelis/trust-client.jks");

        System.setProperty("javax.net.ssl.trustStorePassword", "xxxxc");

        System.setProperty("https.protocols", "SSLv3");
    }


    public void sendData(String content){

        try {

            HttpsURLConnection.setDefaultHostnameVerifier(new HostnameVerifier(){

                @Override
                public boolean verify(String hostname, String session) {
                    // TODO Auto-generated method stub
                    return (true);
                }
            });

            URL url=new URL("https://"+getHost_address()+":"+getSsl_port()+"/test");

            urlConnection=(HttpsURLConnection)url.openConnection();

            urlConnection.setRequestMethod("POST");

            urlConnection.setRequestProperty("User-Agent", "Mozilla/5.0");

            urlConnection.setRequestProperty("Accept-Language", "en-US,en;q=0.5");

            urlConnection.setDoOutput(true);

            urlConnection.connect();

            OutputStream out_stream = urlConnection.getOutputStream();

            DataOutputStream out_stream_writer=new DataOutputStream(out_stream);

            out_stream_writer.writeBytes(content);

            out_stream_writer.close();

        }

        catch (MalformedURLException e) {

            e.printStackTrace();
        }

        catch (java.net.SocketException e){

            e.printStackTrace();
        }

        catch (IOException e) {

            e.printStackTrace();
        }
    }


    public static void main(String[] args) {

        String data="data%3Dhello";

        HTTPSClient secure_client= new HTTPSClient();

        secure_client.sendData(data);

        System.out.print("Done...");

    }

}`

我总是在骡子端收到以下堆栈跟踪：

请记住，如果我使用第二个mule流，使用https-outbound端点以连接到上面讨论的入站端点的流，那么一切正常，没有任何错误。似乎问题在于java客户端代码。有人可以帮助我，因为一个快速而肮脏的集成测试案例开始让我解决问题。 谢谢 范吉利斯

答案 0 :(得分：1)

你的家庭成长的HTTP客户端没有读取Mule的HTTP响应，因此Mule抱怨客户端已经过早关闭了连接。

修复客户端以读取Mule的响应或使用正确的HTTP客户端（例如Apache's HTTP Client）。
