activemq与webservice整合

 在多个系统中可能考虑到远程访问等的，采用WebService方式和远程系统的JMS消息系统交互。本文采用ActiveMQ和JAXWS实现。客户端通过webservice将消息发送给服务端的消息队列。

 package easyway.app.activemq.ws;

 import javax.jws.WebMethod;
 import javax.jws.WebParam;
 import javax.jws.WebService;
 /**
  * 服务端接口
  * @author longgangbai
  *
  */
 @WebService
 public interface HelloWorld {
     /**
      * 启动相关的服务方法
      * @param name
      * @return
      */
     @WebMethod
     String sayHi(@WebParam(name = "name") String name);
 }

 

 

 

 

 package easyway.app.activemq.ws;

 import javax.jws.WebService;

 /**
  * 服务端实现
  * @author longgangbai
  *
  */
 @WebService
 public class HelloWorldImpl implements HelloWorld {
     /*
      * (non-Javadoc)
      * @see test.IHello#sayHi(java.lang.String)
      */
     public String sayHi(String name) {
         return "Hello " + name;
     }
 }

 

 

 

服务端通过WebService发布JMS消息的信息：

 package easyway.app.activemq.ws.server;

 import javax.xml.ws.Endpoint;

 import org.apache.activemq.ActiveMQConnectionFactory;
 import org.apache.activemq.broker.BrokerService;
 import easyway.app.activemq.ws.HelloWorldImpl;

 /**
  * 通过WebService提供本地的JMS服务
  * @author longgangbai
  *
  */
 public class ActiveMQWServer {

     //设置JMS的URI的格式：jms:queue or topic:destination
     private static final String JMS_ENDPOINT_URI = "jms:queue:jaxws.jmstransport.queue?timeToLive=1000"
             + "&jndiConnectionFactoryName=ConnectionFactory"
             + "&jndiInitialContextFactory"
             + "=org.apache.activemq.jndi.ActiveMQInitialContextFactory";

     private ActiveMQWServer() {
     }

     public static void main(String args[]) throws Exception {
         ActiveMQWServer  server=new ActiveMQWServer();
         //初始化Broker的方法
         server.initBrokerService();
         //启动JAXWS相关的 服务
         server.launchJaxwsApi();

         System.out.println("Server ready... Press any key to exit");
         System.in.read();
         System.out.println("Server exiting");
         System.exit(0);
     }
     /**
      * 启动ActiveMQ的Broker
      * @throws Exception
      */
     public void initBrokerService() throws Exception{
         BrokerService  brokerService=new BrokerService();
         brokerService.addConnector( ActiveMQConnectionFactory.DEFAULT_BROKER_BIND_URL);
         brokerService.setDataDirectory("target/activemq-data");
         brokerService.start();
     }


     /**
      * 发布WebService服务
      *
      */
     private  void launchJaxwsApi() {
         Endpoint.publish(JMS_ENDPOINT_URI, new HelloWorldImpl());
     }
 }

 

 

 

客户端通过webservice发送消息到服务端的消息队列：

 package easyway.app.activemq.ws.client;
 import javax.xml.namespace.QName;
 import javax.xml.ws.Service;
 import org.apache.cxf.transport.jms.spec.JMSSpecConstants;
 import easyway.app.activemq.ws.HelloWorld;
 /**
  * 客户端通过WebService向服务端队列中发送消息
  * @author longgangbai
  *
  */
 public final class ActiveMQWSClient {
     //WebService请求的url的路径
     private static final String JMS_ENDPOINT_URI = "jms:queue:jaxws.jmstransport.queue?timeToLive=1000"
             + "&jndiConnectionFactoryName=ConnectionFactory"
             + "&jndiInitialContextFactory"
             + "=org.apache.activemq.jndi.ActiveMQInitialContextFactory";

     private static final QName SERVICE_QNAME =
         new QName("http://ws.activemq.app.easyway/", "HelloWorldImplService");
     private static final QName PORT_QNAME =
         new QName("http://ws.activemq.app.easyway/", "HelloWorldPort");

     private ActiveMQWSClient() {
     }
     /**
      * 客户端调用WS服务
      * @return
      */
     private static HelloWorld createClientJaxWs() {
         //创建相关的 服务
         Service service = Service.create(SERVICE_QNAME);
         // Add a port to the Service
         service.addPort(PORT_QNAME, JMSSpecConstants.SOAP_JMS_SPECIFICATION_TRANSPORTID, JMS_ENDPOINT_URI);
         return service.getPort(HelloWorld.class);
     }

     public static void main(String[] args) throws Exception {

         HelloWorld client = createClientJaxWs();

         String reply = client.sayHi("HI");
         System.out.println(reply);
     }
