This article will explain the example analysis of Hibernate search for you in detail. The editor thinks it is very practical, so I share it with you as a reference. I hope you can get something after reading this article.

How to work:

-Hibernate Search supports distributed configuration using JMS back-end and master/slave (s) indexes

-mater exposes the index through network sharing (for example, through NFS. )

-slave (s) copy the index of mater to local

Version

-Apache Tomcat 6.0.20

-Hibernate Search 3.1.1 GA

-Apache ActiveMQ 5.3.0

-Spring 2.5.6

-XBean-Spring 3.6

${local.index.dir}-directory to store master index

${master.index.dir}-directory to copy master index to, it's shared network location for replication with slave (s)

Configuration of Mater index

The configuration of Mater is a little more complex. The following is a description of the configuration properties

$(local.index.dir)-the directory where the mater index is stored

$(master.index.dir)-copy the target directory of the mater index and locate it over the network for slave (s) to replicate.

First, for simplicity, we run the ActiveMQ mediation on the same server. Therefore, we use a simple embedded mediation configuration in the WEB-INF/activemq.xml file.

Second, you need to configure JNDI resources (JMS Connection Factory and Quene) in web application MEAT-INF/context.xml (Tocmat)

Next, configure Hibernate Searc in the Hibernate.cfg.xml file

Org.hibernate.search.store.FSMasterDirectoryProvider ${local.index.dir} ${master.index.dir} 60

An important difference in code between Master and slave is that master must contain subclasses that implement AbstractJMSHibernateSearchController as listeners, such as

Import javax.jms.MessageListener; import org.hibernate.Session; import org.hibernate.search.backend.impl.jms.AbstractJMSHibernateSearchController; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.stereotype.Service; @ Service public class JMSHibernateSearchController extends AbstractJMSHibernateSearchController implements MessageListener {@ Override protected void cleanSessionIfNeeded (Session session) {/ / clean session here...} @ Override protected Session getSession () {/ / return new session here...}}

Finally, in the configuration file applicationContext.xml file of Spring, add the following configuration

With those configurations in place Hibernate Search master is ready to run.

After the correct configuration, Hibernate Search master is ready to run.

Slave Index configuration

The configuration of Slave (s) is much simpler. Here is the description of the configuration properties.

${server}-run ActiveMQ Mediation Server

${lcoal.index.dir}-the directory where the local index is stored (copy of master)

${mater.index.share}-the network shared directory where the mater index is mounted.

First, we need to configure JNDI resources (JMS Connection Factory and Quene) in the website application MEAT-INF/context.xml (Tocmat).

......

Next we need to configure Hibernate Search in hibernate.cfg.xml

Org.hibernate.search.store.FSSlaveDirectoryProvider ${local.index.dir} ${master.index.share} 60 jms java:comp/env/jms/ConnectionFactory java:comp/env/queue/hibernatesearch org.apache.activemq.jndi.ActiveMQInitialContextFactory

This ends the configuration.

Say something beside the question about the JUnit test. The only problem is that you need to use Spring JNDI templates to simulate JNDI, such as
