I have a Spring application and in it I do not use xml configuration, only Java Config. Everything is OK, but when I try to test it I faced problems wi
You cant use repositories in your configuration class because from configuration classes it finds all its repositories using @EnableJpaRepositories.
@Configuration @EnableWebMvc @EnableTransactionManagement @ComponentScan("com.example") @EnableJpaRepositories(basePackages={"com.example.jpa.repositories"})//Path of your CRUD repositories package @PropertySource("classpath:application.properties") public class JPAConfiguration { //Includes jpaProperties(), jpaVendorAdapter(), transactionManager(), entityManagerFactory(), localContainerEntityManagerFactoryBean() //and dataSource() }
@Service public class RepositoryImpl { @Autowired private UserRepositoryImpl userService; }
@Autowired RepositoryImpl repository;
Usage:
repository.getUserService().findUserByUserName(userName);
Remove @Repository Annotation in ArticleRepository and ArticleServiceImpl should implement ArticleRepository not ArticleService.
If you're using Spring Boot, you can simplify these approaches a bit by adding @SpringBootTest
to load in your ApplicationContext
. This allows you to autowire in your spring-data repositories. Be sure to add @RunWith(SpringRunner.class)
so the spring-specific annotations are picked up:
@RunWith(SpringRunner.class)
@SpringBootTest
public class OrphanManagementTest {
@Autowired
private UserRepository userRepository;
@Test
public void saveTest() {
User user = new User("Tom");
userRepository.save(user);
Assert.assertNotNull(userRepository.findOne("Tom"));
}
}
You can read more about testing in spring boot in their docs.
What you need to do is:
remove @Repository
from ArticleRepository
add @EnableJpaRepositories
to PagesTestConfiguration.java
@Configuration
@ComponentScan(basePackages = {"com.example.core"}) // are you sure you wanna scan all the packages?
@EnableJpaRepositories(basePackageClasses = ArticleRepository.class) // assuming you have all the spring data repo in the same package.
public class PagesTestConfiguration {
@Bean
public ArticleServiceImpl articleServiceImpl() {
ArticleServiceImpl articleServiceImpl = new ArticleServiceImpl();
return articleServiceImpl;
}
}
This is what I have found is the minimal setup for a spring controller test which needs an autowired JPA repository configuration (using spring-boot 1.2 with embedded spring 4.1.4.RELEASE, DbUnit 2.4.8).
The test runs against a embedded HSQL DB which is auto-populated by an xml data file on test start.
The test class:
@RunWith( SpringJUnit4ClassRunner.class )
@ContextConfiguration( classes = { TestController.class,
RepoFactory4Test.class } )
@TestExecutionListeners( { DependencyInjectionTestExecutionListener.class,
DirtiesContextTestExecutionListener.class,
TransactionDbUnitTestExecutionListener.class } )
@DatabaseSetup( "classpath:FillTestData.xml" )
@DatabaseTearDown( "classpath:DbClean.xml" )
public class ControllerWithRepositoryTest
{
@Autowired
private TestController myClassUnderTest;
@Test
public void test()
{
Iterable<EUser> list = myClassUnderTest.findAll();
if ( list == null || !list.iterator().hasNext() )
{
Assert.fail( "No users found" );
}
else
{
for ( EUser eUser : list )
{
System.out.println( "Found user: " + eUser );
}
}
}
@Component
static class TestController
{
@Autowired
private UserRepository myUserRepo;
/**
* @return
*/
public Iterable<EUser> findAll()
{
return myUserRepo.findAll();
}
}
}
Notes:
@ContextConfiguration annotation which only includes the embedded TestController and the JPA configuration class RepoFactory4Test.
The @TestExecutionListeners annotation is needed in order that the subsequent annotations @DatabaseSetup and @DatabaseTearDown have effect
The referenced configuration class:
@Configuration
@EnableJpaRepositories( basePackageClasses = UserRepository.class )
public class RepoFactory4Test
{
@Bean
public DataSource dataSource()
{
EmbeddedDatabaseBuilder builder = new EmbeddedDatabaseBuilder();
return builder.setType( EmbeddedDatabaseType.HSQL ).build();
}
@Bean
public EntityManagerFactory entityManagerFactory()
{
HibernateJpaVendorAdapter vendorAdapter = new HibernateJpaVendorAdapter();
vendorAdapter.setGenerateDdl( true );
LocalContainerEntityManagerFactoryBean factory = new LocalContainerEntityManagerFactoryBean();
factory.setJpaVendorAdapter( vendorAdapter );
factory.setPackagesToScan( EUser.class.getPackage().getName() );
factory.setDataSource( dataSource() );
factory.afterPropertiesSet();
return factory.getObject();
}
@Bean
public PlatformTransactionManager transactionManager()
{
JpaTransactionManager txManager = new JpaTransactionManager();
txManager.setEntityManagerFactory( entityManagerFactory() );
return txManager;
}
}
The UserRepository is a simple interface:
public interface UserRepository extends CrudRepository<EUser, Long>
{
}
The EUser is a simple @Entity annotated class:
@Entity
@Table(name = "user")
public class EUser
{
@Id
@Column(name = "id")
@GeneratedValue(strategy = GenerationType.AUTO)
@Max( value=Integer.MAX_VALUE )
private Long myId;
@Column(name = "email")
@Size(max=64)
@NotNull
private String myEmail;
...
}
The FillTestData.xml:
<?xml version="1.0" encoding="UTF-8"?>
<dataset>
<user id="1"
email="alice@test.org"
...
/>
</dataset>
The DbClean.xml:
<?xml version="1.0" encoding="UTF-8"?>
<dataset>
<user />
</dataset>
