Class JavaEETestInjectorFactory

java.lang.Object

org.wamblee.test.inject.JavaEETestInjectorFactory

All Implemented Interfaces:

org.wamblee.inject.InjectorFactory

public class JavaEETestInjectorFactory
extends Object
implements org.wamblee.inject.InjectorFactory

The test injector factory provides dependency injection of a contextual entity manager using the support/inject mini framework. It supports dependency injection of fields annoted with @PersistenceContext. It only supports one persistence context at the moment. This injector can be easily used together with JpaBuilder.getContextualEntityManager() for obtaining an entity manager in unit test.

The reason it is needed is because standard injection mechanisms (such as weld CDI) do not support entity manager injection in a Java SE environment out of the box.

To use it, construct the factory using one of the available constructors and set InjectorBuilder.setInjectorFactory(InjectorFactory).

Constructor Detail

JavaEETestInjectorFactory

public JavaEETestInjectorFactory(org.wamblee.inject.InjectorFactory aInjectorFactory)

Constructs the factory.

Parameters:

aInjectorFactory - Injector factory to delegate to.

JavaEETestInjectorFactory

public JavaEETestInjectorFactory()

Constructs the factory with the default injector factory obtained from InjectorBuilder.getInjector().

Method Detail

addEntityManagerBinding

public JavaEETestInjectorFactory addEntityManagerBinding(javax.persistence.EntityManager aEntityManager)

Adds default entity manager binding. Any field annotated with @PersistenceContext and of type entity manager will get injected.

Parameters:

aEntityManager - Entitymanager object to inject.

Returns:

Factory to allow chaining.

addBinding

public JavaEETestInjectorFactory addBinding(Binding aBinding)

Adds another custom injection binding.

Parameters:

aBinding - Injection binding to use.

Returns:

the factoryto allow chaining.

create

public org.wamblee.inject.Injector create(Class aClass)

Specified by:

create in interface org.wamblee.inject.InjectorFactory
