Getting Started with Infinispan

This tutorial is for developers who are just beginning to learn hibernate-search and trying to set up a demo project. Most of the codes are copied from the hibernate-search documentation: https://docs.jboss.org/hibernate/stable/search/reference/en-US/html_single/

What we need:

• eclipse-neon
• hibernate-search 5.7.0
• wildfly 10.1.0.Final
• infinispan 8.2.6 (infinispan-as-embedded-modules-8.2.6.Final.zip), download this from the infinispan website and extract in your wildfly modules folder - do not forget to do this otherwise you'll have a missing class exception

Note:
I created my project using javaee7 maven archetype.

Since hibernate-search has already explained a lot we will just take note of the most important pieces:

1. persistence.xml
   

   <property name="hibernate.show_sql" value="true" />
   <!-- Enables second level cache, call find after insert and no query in the database will be issue -->
   <property name="hibernate.cache.use_second_level_cache" value="false"/>
   <!-- Enable query cache -->
   <property name="hibernate.cache.use_query_cache" value="false"/>
   <!-- optional -->
   <property name="hibernate.search.default.directory_provider"
    value="infinispan" />
   <property name="hibernate.search.infinispan.cache_jndiname"
    value="java:jboss/infinispan/broodcampHibernateSearch" />
   <!-- <property name="hibernate.search.default.directory_provider" -->
   <!-- value="filesystem" /> -->
   <property name="hibernate.search.default.indexBase" value="c:/temp/lucene/indexes" />

   
   In here we set the directory_provider to infinispan, then we also set the cache JNDI name. So in wildfly's standalone.xml, we must add the cache below:

   <cache-container name="broodcamp" default-cache="broodcamp-hibernate-search">
    <local-cache name="broodcamp-hibernate-search" jndi-name="java:jboss/infinispan/broodcampHibernateSearch">
     <file-store path="c:/temp/lucene/indexes" passivation="true" purge="false"/>
    </local-cache>
   </cache-container>

2. Create a class Author and Book from hibernate search documentation.
3. In our pom we must define the following dependencies:

   <dependency>
    <groupId>org.hibernate</groupId>
    <artifactId>hibernate-search-orm</artifactId>
   </dependency>
   
   <dependency>
    <groupId>org.infinispan</groupId>
    <artifactId>infinispan-directory-provider</artifactId>
    <version>8.2.4.Final</version>
    <scope>provided</scope>
   </dependency>
   

4. Now let's create an arquillian test:
1. arquillian.xml

   <?xml version="1.0" encoding="UTF-8"?>
   <arquillian xmlns="http://jboss.org/schema/arquillian"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://jboss.org/schema/arquillian
           http://jboss.org/schema/arquillian/arquillian_1_0.xsd">
   
    <defaultProtocol type="Servlet 3.0" />
   
    <container qualifier="wildfly" default="true">
     <configuration>
      <property name="jbossHome">C:\Java\jboss\wildfly-10.1.0.Final</property>
     </configuration>
    </container>
   
    <engine>
     <property name="deploymentExportPath">target/deployments</property>
    </engine>
   
   </arquillian>
   

   Set jbossHome to the correct value.
2. Create our arquillian test class:

     // create native Lucene query using the query DSL

     // execute search
     List<Book> result = (List<Book>) jpaQuery.getResultList();
   
     log.info("Record found=" + result.size());
     result.forEach(p -> log.info(p.toString()));
   
     assertEquals(5, result.size());
    }
   
   }

And we are done. To run the arquillian test execute: mvn clean test -Parq-wildfly-managed. This comes from the javaee7 archetype.

Note: If you want to cache the result of a query, set hint:

TypedQuery query = em.createQuery("from Entity", Entity.class);
query.setHint("org.hibernate.cacheable", Boolean.TRUE);
List events = query.getResultList();
