Hibernate version mismatch in WildFly 10.0

问题:

I have 2 projects, one is a normal java project (with maven): core, and the other is non-maven dynamic web project: webapi. The later acts as a rest layer on top of core.

core uses hibernate without any problem. It defines the persistence.xml (inside src/META-INF/) as follows:

<?xml version="1.0" encoding="utf-8"?>

<persistence xmlns="http://java.sun.com/xml/ns/persistence"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"
    version="2.0">

    <persistence-unit name="app" transaction-type="RESOURCE_LOCAL">

        <class>data.entities.Anything</class>
        <class>data.entities.Something</class>

        <properties>
            <property name="javax.persistence.jdbc.driver" value="com.microsoft.sqlserver.jdbc.SQLServerDriver"></property>
            <property name="javax.persistence.jdbc.url" value="jdbc:sqlserver://localhost;databaseName=AppDb"></property>
            <property name="javax.persistence.jdbc.user" value="****"></property>
            <property name="javax.persistence.jdbc.password" value="****"></property>
            <property name="hibernate.default_schema" value="dbo"></property>           
            <property name="hibernate.dialect" value="org.hibernate.dialect.SQLServer2008Dialect"></property>
            <property name="hibernate.hbm2ddl.auto" value="update"></property>
        </properties>
    </persistence-unit>
</persistence>

webapi uses core and try to expose core's functionality as service. I have added core to both "Java Build Path", and "Deployment Assembly" of webapi. As I am using SQL Server, sqljdbc42.jar is also added to "Deployment Assembly" of webapi.

However, when I try to deploy webapi in WildFly 10.0, the hibernate entity manager is not instantiated properly. My primary suspect here the version mismatch of hibernate-core in core, and webapi. core uses hibernate-core 5.2.4.Final, whereas for webapi it is coming from WildFly runtime, which is 5.0.7.Final. This can be seen from the logs below:

How this can be rectified?

回答1:

This can be solved by changing the version of your Hibernate core in Wildfly. In order to do so, change your META-INF/persistence.xml file like this :

<properties>
    <property name="jboss.as.jpa.providerModule" value="org.hibernate:5.2" />
    ...
</properties>

To add some micro version:

<property name="jboss.as.jpa.providerModule" value="org.hibernate:5.2.4.Final" />
