All Implemented Interfaces:
Test
Direct Known Subclasses:
AbstractAspectjJpaTests
public abstract class AbstractJpaTests
extends AbstractAnnotationAwareTransactionalTests

Convenient support class for JPA-related tests. Offers the same contract as AbstractTransactionalDataSourceSpringContextTests and equally good performance, even when performing the instrumentation required by the JPA specification.

Exposes an EntityManagerFactory and a shared EntityManager. Requires an EntityManagerFactory to be injected, plus the DataSource and JpaTransactionManager through the superclass.

When using Xerces, make sure a post 2.0.2 version is available on the classpath to avoid a critical bug that leads to StackOverflow. Maven users are likely to encounter this problem since 2.0.2 is used by default.

A workaround is to explicitly specify the Xerces version inside the Maven pom: 

 <dependency>
   <groupId>xerces</groupId>
     <artifactId>xercesImpl</artifactId>
   <version>2.8.1</version>
 </dependency>

Since:
2.0

Field Detail

entityManagerFactory

protected javax.persistence.EntityManagerFactory entityManagerFactory

sharedEntityManager

protected javax.persistence.EntityManager sharedEntityManager
Subclasses can use this in test cases. It will participate in any current transaction.

Constructor Detail

AbstractJpaTests

public AbstractJpaTests()
Method Detail

setEntityManagerFactory

public void setEntityManagerFactory(javax.persistence.EntityManagerFactory entityManagerFactory)

createContainerManagedEntityManager

protected javax.persistence.EntityManager createContainerManagedEntityManager()
Create an EntityManager that will always automatically enlist itself in current transactions, in contrast to an EntityManager returned by EntityManagerFactory.createEntityManager() (which requires an explicit joinTransaction() call).

shouldUseShadowLoader

protected boolean shouldUseShadowLoader()
Subclasses should override this method if they wish to disable shadow class loading. Do this only if instrumentation is not required in your JPA implementation.

Returns:
whether to disable shadow loading functionality

setDirty

public void setDirty()
Description copied from class: AbstractSingleSpringContextTests
Called to say that the "applicationContext" instance variable is dirty and should be reloaded. We need to do this if a test has modified the context (for example, by replacing a bean definition).

Overrides:
setDirty in class AbstractSingleSpringContextTests

runBare

public void runBare()
             throws Throwable
Description copied from class: AbstractAnnotationAwareTransactionalTests
Overridden to populate transaction definition from annotations.

Overrides:
runBare in class AbstractAnnotationAwareTransactionalTests
Throws:
Throwable

cacheKeys

protected String cacheKeys()

createShadowingClassLoader

protected ClassLoader createShadowingClassLoader(ClassLoader classLoader)
NB: This method must not have a return type of ShadowingClassLoader as that would cause that class to be loaded eagerly when this test case loads, creating verify errors at runtime.

customizeResourceOverridingShadowingClassLoader

protected void customizeResourceOverridingShadowingClassLoader(ClassLoader shadowingClassLoader)
Customize the shadowing class loader.

Parameters:
shadowingClassLoader - this parameter is actually of type ResourceOverridingShadowingClassLoader, and can safely to be cast to that type. However, the signature must not be of that type as that would cause the present class loader to load that type.

getActualOrmXmlLocation

protected String getActualOrmXmlLocation()
Subclasses can override this to return the real location path for orm.xml or null if they do not wish to find any orm.xml

Returns:
orm.xml path or null to hide any such file
