访问地址： EHCACHE: It is widely used type of cache.

Replication: If you are using mulitple application server and you need to have same copy of cache at every application server node, then you can use EHCAHE Replication.

I am going to demostrate how EHCACHE replication achieved with Java Message Service in Spring Web Application.

We have choice of using Open MQ and Active MQ. These are open source message queues. I am using Active MQ.

Configuration:

A)Active MQ Setup

1. You need to download Active MQ server from this link.

I have used -apache-activemq-4.1.0-incubator

2.Extract it.

3.go to follwing path-

—\apache-activemq-4.1.0-incubator\bin

run activemq.bat

ActiveMQ’s default port is 61616.

B)Spring Web App Configuration

3.Spring-context.xml

–We have to create bean -cacheManager, and set configuration file location in property.

1. ehcache.xml- This fiile actual configuration for Ehcache

5.TestActiveMQInitialContextFactory.java

We have specified

initialContextFactoryName=com.arceler.ehcache.TestActiveMQInitialContextFactory

So we have give following file.

import java.net.URISyntaxException;import java.util.Hashtable;import java.util.Map;import java.util.concurrent.ConcurrentHashMap;import javax.naming.Context;import javax.naming.NamingException;import net.sf.ehcache.distribution.jms.JMSUtil;import org.apache.activemq.jndi.ActiveMQInitialContextFactory;public class TestActiveMQInitialContextFactory extends ActiveMQInitialContextFactory {
   /*** Creates an initial context with* {@inheritDoc}*/@Override@SuppressWarnings("unchecked")public Context getInitialContext(Hashtable environment) throws NamingException {Map
   
     data = new ConcurrentHashMap
    
     ();String replicationTopicConnectionFactoryBindingName = (String)environment.get(JMSUtil.TOPIC_CONNECTION_FACTORY_BINDING_NAME);if(replicationTopicConnectionFactoryBindingName!=null){try {data.put(replicationTopicConnectionFactoryBindingName, createConnectionFactory(environment));} catch (URISyntaxException e) {throw new NamingException("Error initialisating TopicConnectionFactory with message " + e.getMessage());}}String getQueueConnectionfactoryBindingName = (String)environment.get(JMSUtil.GET_QUEUE_CONNECTION_FACTORY_BINDING_NAME);try {data.put(getQueueConnectionfactoryBindingName, createConnectionFactory(environment));} catch (URISyntaxException e) {throw new NamingException("Error initialisating TopicConnectionFactory with message " + e.getMessage());}String replicationTopicBindingName = (String)environment.get(JMSUtil.REPLICATION_TOPIC_BINDING_NAME);String getQueueBindingName = (String)environment.get(JMSUtil.GET_QUEUE_BINDING_NAME);if(replicationTopicBindingName!=null){data.put(replicationTopicBindingName, createTopic(replicationTopicBindingName));}data.put(getQueueBindingName, createQueue(getQueueBindingName));return createContext(environment, data);}}
