!!Local Container Manager vs. Local Entity Manager
Neben dem LocalContainerEntityManagerFactoryBean gibt es noch den LocalEntityManagerFactoryBean, der einfacher zu konfigurieren und zunächst ohne Container, das heißt JNDI auskommt:
{{{
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalEntityManagerFactoryBean" lazy-init="true">
<property name="persistenceUnitName" value="subflowDb"/>
<property name="jpaProperties">
<props>
<prop key="hibernate.connection.url">jdbc:hsqldb:file:${project.build.directory}/hsql/data</prop>
<prop key="hibernate.connection.driver_class">org.hsqldb.jdbcDriver</prop>
<prop key="hibernate.dialect">org.hibernate.dialect.HSQLDialect</prop>
<prop key="hibernate.connection.username">sa</prop>
<prop key="hibernate.connection.password"></prop>
<prop key="hibernate.show_sql">true</prop>
</props>
</property>
</bean>
}}}
Allerdings ist es auch möglich, den LocalContainerEntityManagerFactoryBean lokal zu konfigurieren, sodass er z.B. aus einem JUnit-Test mit Spring heraus läuft:
{{{
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="persistenceUnitManager">
<bean id="persistenceUnitManager" class="org.springframework.orm.jpa.persistenceunit.DefaultPersistenceUnitManager">
<property name="persistenceXmlLocations" value="classpath*:META-INF/persistence.xml"/>
<property name="defaultDataSource" ref="dataSource"/>
</bean>
</property>
</bean>
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
<property name="driverClassName" value="${jdbc.driverClassName}"/>
<property name="url" value="${jdbc.url}"/>
<property name="username" value="${jdbc.username}"/>
<property name="password" value="${jdbc.password}"/>
<property name="maxActive" value="100"/>
<property name="maxIdle" value="30"/>
<property name="maxWait" value="16000"/>
<property name="minIdle" value="0"/>
</bean>
}}}
Der Test sieht dann so aus:
{{{
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration("classpath:META-INF/testApplicationContext.xml")
// @TransactionConfiguration(defaultRollback = false)
public class SpringDBTest {
@Test
@Transactional
public void test() {
Criteria criteria = ((Session)entityManager.getDelegate()).createCriteria(Test.class);
...
}
}
}}}
