Spring Bean sessionFactory with NullPointerException error

Spring Bean sessionFactory with NullPointerException error

Good morning.

I'm trying to make a setting in the spring-jpa.xml file to support a multitenancy architecture by separating each client by Schema. I use a dataSource that has been configured in JBoss Wildfly to connect to the database where the schemas are.

What's missing in the settings?

Context initialization failed: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in ServletContext resource [/WEB-INF/spring/spring-jpa.xml]: Invocation of init method failed; nested exception is java.lang.NullPointerException.

Since you can change the implementation of TransactionManager of your application, I suggest the following approach:

applicatioContext.xml

<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:jee="http://www.springframework.org/schema/jee" xmlns:jpa="http://www.springframework.org/schema/data/jpa"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
                       http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd
                       http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
                       http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-3.0.xsd
                       http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
                       http://www.springframework.org/schema/data/jpa http://www.springframework.org/schema/data/jpa/spring-jpa-1.0.xsd
                       http://www.springframework.org/schema/context http://www.springframework.org/schema/task/spring-context-3.0.xsd">
    <jee:jndi-lookup id="dataSource"
        jndi-name="java:jboss/datasources/dataSource"
        lookup-on-startup="true" proxy-interface="javax.sql.DataSource" />

    <!-- EM do container -->
    <jee:jndi-lookup id="entityManager"
        jndi-name="java:comp/env/persistence/meu-em"
        lookup-on-startup="true" proxy-interface="javax.persistence.EntityManager" />

    <!-- TransactionManager do Container -->
    <bean id="transactionManager"
        class="org.springframework.transaction.jta.JtaTransactionManager">
    </bean>
</beans>

Notice that there is no setting for EntityManager here. Since we're using Wildfly, I'll let him create it. I only make reference to JNDI. Spring will do the rest.

persistence.xml

<persistence version="2.0"
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">
    <persistence-unit name="persistenceUnit" transaction-type="JTA">
        <!-- Using the example datasource set up by WildFly 8 For your application, 
            set up a managed datasource and use that instead -->
        <jta-data-source>java:jboss/datasources/dataSource</jta-data-source>
        <!-- 
          ref.: http://docs.jboss.org/hibernate/stable/entitymanager/reference/en/html/configuration.html
         -->
        <properties>
            <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQL82Dialect" />
            <property name="hibernate.show_sql" value="true" />
            <property name="hibernate.multiTenancy" value="SCHEMA" />
            <property name="hibernate.multi_tenant_connection_provider" value="com.package.security.MultiTenantConnectionProviderImpl" />
            <property name="hibernate.tenant_identifier_resolver" value="com.package.security.MultiTenantIdentifierResolverImpl" />
            <!-- scan das suas entidades -->
            <property name="hibernate.archive.autodetection" value="class"/>
        </properties>
    </persistence-unit>
</persistence>

Since it is Wildfly that will manage EM you have to define it in the container itself. This file can be in your classpath and be distributed along with your application or be installed as a Wildfly module that will be used by your application. It depends on your scenario.

Now you need to reference the EM in your web application so Wildfly know you'll use the feature. In your web.xml file, add the following:

<persistence-context-ref>
    <persistence-context-ref-name>persistence/meu-em</persistence-context-ref-name>
    <persistence-unit-name>persistenceUnit</persistence-unit-name>
</persistence-context-ref>

In your data access layer, reference EntityManager via Spring injection:

@Inject
public void setEntityManager(EntityManager entityManager) {
    this.entityManager = entityManager;
}

You can use @Autowire if you do not use the common JSR-330 interfaces.

I can not test here because I have no project with configuration via xml . If you give a bough, let me know in the comments so I can get it right and help you.

As a reference, I have a project in Github using the data layer configuration via class ( @Configuration ).
