Implementation of the Hibernate Level 2 Cache with Couchbase cluster as a backend store.
This is a beta version. The current version of the library does not support a lot of settings of the Couchbase client.
Copyright 2014 Couchbase, Inc.
The library is licensed under Apache 2.0 license. See LICENSE.txt
for the full license text.
- Compiled and installed hibernate-memcached
- Installed and configured Couchbase cluster.
- Configured bucket to store the cached objects.
- Virtual Box and Vagrant (to run tests).
To build the project you'll need the JDK 1.7+ and Maven 3+.
For a quick build, please run mvn install -Dmaven.test.skip=true
to compile without running any tests.
To make the build with running all the tests:
- Run
vagrant up
to start and initialize Vagrant virtual box. It will take some time to install the dependencies. - Run the Maven build:
mvn install
.
After the build you can either copy the result jar from target/couchbase-l2-hibernate-1.0-SNAPSHOT.jar
or add it to your project as a Maven dependency:
<dependency>
<groupId>net.thumbtack.couchbase-l2</groupId>
<artifactId>couchbase-l2-hibernate</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
To start using the Couchbase cluster as a cache in Hibernate you need to configure Couchbase and make some changes in your persistence.xml
file.
- Create a new bucket in Couchbase admin panel. Write down the bucket name and the password.
- Add
couchbase-l2-hibernate-1.0-SNAPSHOT.jar
and all dependencies to your project classpath. - In
persistence.xml
add the following lines (common configuration). Please update the Couchbase URLs, bucket name and password with actual values.
<property name="couchbase.cache.servers"
value="http://couchbase-cluster-node01:8091/pools,
http://couchbase-cluster-node02:8091/pools"/>
<property name="couchbase.cache.bucket.name" value="l2-cache"/>
<property name="couchbase.cache.bucket.password" value="cachepwd"/>
<property name="couchbase.cache.ttl" value="600"/>
<property name="hibernate.cache.region.factory_class" value="com.googlecode.hibernate.memcached.MemcachedRegionFactory" />
<property name="hibernate.memcached.memcacheClientFactory" value="net.thumbtack.hibernate.couchbase.CouchbaseClientFactory" />
