Using Hibernate 5.2 with Wilfly 10 in Docker

The 1st of June Hibernate 5.2 was released, this release has some interesting features, like the consolidation of JPA in the core, and support for java 8 API’s.

Following the Hibernate official update guide, we need to replace the jars in the wildfly/modules folder.

In this blog, we will use the base docker image of Wildfly, with the tag 10.0.0.Final.

First, we create a simple Dockerfile:

FROM jboss/wildfly:10.0.0.Final
MAINTAINER Arturo Volpe <arturovolpe@gmail.com>

First, we need to get all the jars in the right place, the jars are available in Maven Central, so we add to our this

RUN cd $JBOSS_HOME/modules/system/layers/base/org/hibernate/main && \
    curl -O http://central.maven.org/maven2/org/hibernate/hibernate-core/5.2.0.Final/hibernate-core-5.2.0.Final.jar && \
    curl -O http://central.maven.org/maven2/org/hibernate/hibernate-envers/5.2.0.Final/hibernate-envers-5.2.0.Final.jar

RUN cd $JBOSS_HOME/modules/system/layers/base/org/hibernate/infinispan/main/ && \
    curl -O http://central.maven.org/maven2/org/hibernate/hibernate-infinispan/5.2.0.Final/hibernate-infinispan-5.2.0.Final.jar && \

This will download the 5.2 jars in the correct place (we need to replace hibernate-orm, envers, and infinispan).

The next step is remove the references and the jars of the previous release (for the base image, hibernate 5.0.7)

# Replace hibernate, hibernate-envers
RUN sed -i.bak "s/5.0.7/5.2.0/" module.xml && \
    sed -i.bak "/entitymanager/d" module.xml && \
    sed -i.bak "/java8/d" module.xml && \
    rm *.bak

# Replace infinispan
RUN rm *5.0.7.Final.jar && \
    sed -i.bak "s/5.0.7/5.2.0/" module.xml && \
    rm *.bak

And we are done, with this, hibernate by default must provide the 5.2.0.Final version of Hibernate.

To use this, we can do something like this:

@PersistenceContext
EntityManager em;

public Session getSession() {
    return em.unwrap(Session.class);
}
