Spring+jms+activemq+tomcat Implementing a messaging service

It programmer development Essentials-all kinds of resources download list, history of the most IT resources, personal collection summary.

Based on Spring+jms+activemq+tomcat, the version I'm using is as follows: Spring 2.5 ActiveMQ 5.4.0 Tomcat 6.0.30

The following learning and configuration, to achieve the basic message service functions: Send and receive. Spring provides very good support for JMS, which can be easily implemented with Jmstemplate for messaging services. Here, our messaging service does not involve transaction management. The following is a brief description of the implementation process:

First look at the contents of our final spring configuration file Applicationcontext.xml, as follows:<?xmlVersion= "1.0" encoding= "UTF-8"?><beansxmlns= "Http://www.springframework.org/schema/beans" xmlns:amq= "Http://activemq.apache.org/schema/core" xmlns:xsi = "Http://www.w3.org/2001/XMLSchema-instance" xsi:schemalocation= "Http://www.springframework.org/schema/beans Http://www.springframework.org/schema/beans/spring-beans-2.5.xsd Http://activemq.apache.org/schema/core http://a Ctivemq.apache.org/schema/core/activemq-core.xsd "><beanId= "Listenercontainer" class= "Org.springframework.jms.listener.DefaultMessageListenerContainer"> <propertyName= "ConnectionFactory" ref= "ConnectionFactory"></property><propertyName= "Destination" ref= "MessageQueue"></property><propertyName= "MessageListener" ref= "Receivemessagelistener"></property></bean><beanId= "ConnectionFactory" class= "Org.springframework.jndi.JndiObjectFactoryBean"> <propertyName= "Jndiname" value= "Java:comp/env/myjms/connectionfactory"></property></bean><beanId= "MessageQueue" class= "Org.springframework.jndi.JndiObjectFactoryBean"><propertyName= "Jndiname" value= "Java:comp/env/myjms/messagequeue"></property></bean><beanId= "Receivemessagelistener" class= "Org.shirdrn.spring.jms.integration.ReceiveMessageListener"></bean><beanId= "Messagesender" class= "Org.shirdrn.spring.jms.integration.MessageSender"><propertyName= "Jmstemplate" ref= "Jmstemplate"></property></bean><beanId= "Jmstemplate" class= "Org.springframework.jms.core.JmsTemplate"> <propertyName= "ConnectionFactory" ref= "ConnectionFactory"></property><propertyName= "Defaultdestination" ref= "MessageQueue"></property></bean><beanId= "Sendmessagecontroller" class= "Org.shirdrn.spring.jms.integration.SendMessageController"><propertyName= "Messagesender" ref= "Messagesender"/><propertyName= "Successview" value= "/success"/></bean><beanId= "urlmapping" class= "org.springframework.web.servlet.handler.SimpleUrlHandlerMapping"><propertyName= "Mappings"> <props><propkey= "/sendmessage.do">Sendmessagecontroller</prop></props></property></bean><beanId= "Viewresolver" class= "Org.springframework.web.servlet.view.InternalResourceViewResolver"><propertyName= "Requestcontextattribute" value= "RC"/><propertyName= "Viewclass" value= "Org.springframework.web.servlet.view.JstlView"/><propertyName= "prefix" value= "/"/><propertyName= "suffix" value= ". JSP"/> </bean></beans>

We use spring's org.springframework.jms.listener.DefaultMessageListenerContainer to gather messages by setting up a message listener, specifically implementing the class as ORG.SHIRDRN.SPRING.JMS . Integration. Receivemessagelistener, the code is as follows: PackageOrg.shirdrn.spring.jms.integration;ImportJavax.jms.JMSException;ImportJavax.jms.Message;ImportJavax.jms.MessageListener;ImportJavax.jms.TextMessage;ImportOrg.apache.log4j.Logger; PublicclassReceivemessagelistenerImplementsMessageListener {PrivateStaticFinalLogger LOG = Logger.getlogger (Receivemessagelistener.class); PublicvoidOnMessage (Message message) {if(MessageinstanceofTextMessage) {TextMessage text = (textmessage) message;Try{Log.info ("Received message:" + text.gettext ()); }Catch(JMSException e)               {E.printstacktrace (); }           }       }      }

Above, listen to the message sent, and receive processing, we simply print out a log content.

For Listenercontainer, Also need to inject connection factory connectionfactory and message purpose destination These two properties: connectionfactory we use ACTIVEMQ org.apache.activemq.ActiveMQConnectionFacto Ry, and through the Jndi service, bind to the name java:comp/env/myjms/connectionfactory on While the destination property is bound to the name through the Jndi service by using ACTIVEMQ's Org.apache.activemq.command.ActiveMQQueue message queue java:comp/env/myjms/ On the MessageQueue. So, in the <Context> element in Tomcat's Conf/context.xml, add the following configuration: <resource  name= "myjms/ ConnectionFactory "        auth=" Container "          type= "Org.apache.activemq.ActiveMQConnectionFactory"          description= "Jms connection factory"        factory= " Org.apache.activemq.jndi.JNDIReferenceFactory "        brokerurl=
