如何将Soap消息发送到actiemq队列?


我正在做一个向第三方网络服务发送肥皂请求的项目,我是java开发的新手。到目前为止,我有一个基本的代码来创建肥皂消息,发送它,然后接收响应;消息包含一个xml文件作为base64字符串文件。

我使用的代码是工作,但我需要确保肥皂请求将成功地传递消息在较短的时间内,(我有48小时来保证传递),所以如果有某种网络故障或网络服务不可用,我的代码会产生一个错误,并停止程序的其余部分。

// Create SOAP Connection
        SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
        SOAPConnection soapConnection = soapConnectionFactory.createConnection();

        // Send SOAP Message to SOAP Server
        String url = "https://facturaelectronica.dian.gov.co/habilitacion/B2BIntegrationEngine/FacturaElectronica";
        SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(), url);

        // print SOAP Response
        System.out.print("Response SOAP Message:");
        soapResponse.writeTo(System.out);


        soapConnection.close();

我读到过,可以将肥皂请求发送到jms qeue,这样我就可以确保整个程序在网络故障的情况下正确执行,但是,据我所知,我需要将肥皂消息转换为jms消息,我还没有弄清楚。我发现你可以用它来实现转换:

 //Convert SOAP to JMS message.
    Message m = MessageTransformer.SOAPMessageIntoJMSMessage                                                    (soapMessage,session);

基于此留档:https://docs.oracle.com/cd/E19340-01/820-6767/aeqgk/index.html

所以我创建了一个类来调用ToJms进行转换:

import javax.xml.soap.SOAPMessage;
import javax.xml.soap.SOAPPart;

import org.apache.activemq.ActiveMQConnection;
import org.apache.activemq.ActiveMQConnectionFactory;

import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPBody;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.MessageFactory;
import javax.xml.soap.AttachmentPart;
import javax.xml.soap.Name;

import java.net.URL;
import javax.activation.DataHandler;

import com.sun.messaging.Queue;
import com.sun.messaging.xml.MessageTransformer;

import javax.jms.ConnectionFactory;
import javax.jms.Connection;
import javax.jms.JMSException;
import javax.jms.Session;
import javax.jms.Message;
import javax.jms.Session;
import javax.jms.Topic;
import javax.jms.MessageProducer;

/**
 * This example shows how to use the MessageTransformer utility to send SOAP
 * messages with JMS.
 * <p>
 * SOAP messages are constructed with javax.xml.soap API.  The messages
 * are converted with MessageTransformer utility to convert SOAP to JMS
 * message types.  The JMS messages are then published to the JMS topics.
 */
public class ToJms {

    ConnectionFactory        connectionFactory = null;
    Connection               connection = null;
    Session                  session = null;
    Topic                    topic = null;
    Queue                    queue = null;

    MessageProducer          msgProducer = null;
    private static String url = ActiveMQConnection.DEFAULT_BROKER_URL;


    /**
     * default constructor.
     */
    public ToJms(String QueueName) {
        init(QueueName);
    }

    /**
     * Initialize JMS Connection/Session/Topic and Producer.
     */
    public void init(String topicName) {
        try {
//            connectionFactory = new com.sun.messaging.ConnectionFactory();
//            connection = connectionFactory.createConnection(localhost:6161);
            ConnectionFactory connectionFactory = new ActiveMQConnectionFactory(url);
            Connection connection = connectionFactory.createConnection();
            session = connection.createSession(true, Session.AUTO_ACKNOWLEDGE);

            topic = session.createTopic(topicName);
            msgProducer = session.createProducer(topic);
        } catch (JMSException jmse) {
            jmse.printStackTrace();
        }
    }

    /**
     * Send SOAP message with JMS API.
     */
    public void send (SOAPMessage soapMessage) throws Exception {

                /**
         * Convert SOAP to JMS message.
         */
        Message message = MessageTransformer.SOAPMessageIntoJMSMessage( soapMessage, session );

        /**
         * publish JMS message.
         */
        msgProducer.send( message );
    }

    /**
     * close JMS connection.
     */
    public void close() throws JMSException {
        connection.close();
    }

    /**
     * The main program to send SOAP messages with JMS.
     */
    public static void main (String[] args) {

        String topicName = "TestTopic";

        if (args.length > 0) {
            topicName = args[0];
        }
        try {
            ToJms ssm = new ToJms(topicName);
           // ssm.send();
            ssm.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

然后在我的主课上实现它:

    ToJms ssm=new ToJms("SoapDian");
    ssm.send(createSOAPRequest());
    ssm.close();

我得到了下一个错误:

我在试图找到oracle指定的库时遇到了很多麻烦,因为在goolge上有很多不同的结果,我必须尝试很多,直到导入成功。

所以我想知道这里是否有人知道如何做到这一点,或者有更好的解决方案将肥皂消息发送到actiemq队列。

谢谢。

我找不到一种方法来完成这项工作,所以我所做的就是将肥皂消息转换为字符串,将其发送到actiemq,然后在消费时执行反向过程。
