I'm using JUnit4 with SpringJUnit4ClassRunner
to write some test classes and I need to access the application persistence context inside a static method, a method with the @BeforeClass
annotation. My actual code is seen below:
@ContextConfiguration(locations = {
"classpath:category-datasource-config.xml"
, "classpath:category-persistence-context.xml"
, "classpath:spring-data-config-test.xml"
})
public class CategoryTopographicalViewIntegrationTest extends BaseTest {
@Autowired
private CategoryService categoryService;
@PersistenceContext
private EntityManager em;
@BeforeClass
public static void setupDatabase() {
// I need the EntityManager HERE!
suppressCategories(Tenant.MCOM, new Long[] { 16906L, 10066L, 72795L, 72797L, 72799L, 72736L }, ContextType.DESKTOP);
suppressCategories(Tenant.BCOM, new Long[] { 1001940L }, ContextType.DESKTOP);
if (!contextualCategoryExists(9326L, ContextType.DESKTOP)) {
ContextualCategoryEntity cce = new ContextualCategoryEntity();
cce.setCategory(em.find(CategoryEntity.class, 9326L));
cce.setCategoryName("Immutable Collections");
cce.setContextType(ContextType.DESKTOP);
cce.setSequence(30);
cce.setSuppressed(Boolean.FALSE);
em.persist(cce);
}
em.flush();
}
...
}
How can I accomplish that? I do not have a persistence.xml
file, the persistence context bean is configured inside a Spring XML config file:
<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
<property name="packagesToScan" value="com.macys.stars.category.domain"/>
<property name="dataSource" ref="dataSource"/>
<property name="jpaVendorAdapter" ref="hibernateVendorAdapter"/>
</bean>
Thanks in advance!
With JUnit 4 it is not possible to access Spring beans in a static
@BeforeClass
method. Beans from the ApplicationContext
can only be injected once the test class has been instantiated.
However, you can implement a custom TestExecutionListener
(eg, by extending AbstractTestExecutionListener
and overriding the beforeTestClass(...)
method) and register it via @TestExecutionListeners
. Your listener can then do the work of your @BeforeClass
method by explicitly retrieving the necessary beans from the ApplicationContext
in the TestContext
.
Hope this helps!
