Spring JPA存储库findAll在JUnit测试中不返回任何数据

Question

I have an issue with my integration tests of my jpa repository in a spring-boot web application. A test of a service method fails, because the accessed repository does not return any results. But the transaction for the database should contain data, because the SQL script gets executed correctly, after the log shows that the transaction for the test has begun.

If the code is used as Web-service, the data can be accessed as expected, so it seems to be a problem with the transaction of the test.

Can anyone point me to the right direction to solve this issue?

PS: @Data is from https://projectlombok.org/ , which creates a complete bean.

Here is my corresponding code:

Entity

@Entity
@Data
public class ConcreteEvent {
   @Id
   @GeneratedValue(strategy = GenerationType.AUTO)
   private long id;
   private String caption;
   private String description;
   @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
   private DateTime startDate;
   @Type(type = "org.jadira.usertype.dateandtime.joda.PersistentDateTime")
   private DateTime endDate;
}

Repository

public interface ConcreteEventRepository 
    extends PagingAndSortingRepository<ConcreteEvent, Long> {
}

Service

@Service
public class CalenderEventServiceImpl implements CalendarEventService {

    @Autowired
    private ConcreteEventRepository concreteEventRepository;

    @Override
    public List<ConcreteEvent> getCalendarEventsForDay(DateTime day) {
        List<ConcreteEvent> list = new ArrayList<>();
        Iterable<ConcreteEvent> findAll = concreteEventRepository.findAll();
        findAll.forEach(list::add);
        return list;
    }
}

Test

@ActiveProfiles("test")
@SpringApplicationConfiguration(Application.class)
@WebAppConfiguration
@DirtiesContext
@TestExecutionListeners({ DependencyInjectionTestExecutionListener.class,
    DirtiesContextTestExecutionListener.class })
public class CalendarEventServiceTest 
    extends AbstractTransactionalJUnit4SpringContextTests {

    @Autowired
    private CalendarEventService calendarEventService;

    @Before
    public void initialize()
    {
        executeSqlScript("classpath:concreteEvents.sql", false);
    }

    @Test
    public void testGetCalendarEventsForDay_UseConcreteEvents() {
        List<ConcreteEvent> calendarEventsForDateTime = calendarEventService.getCalendarEventsForDay(new DateTime(2016, 06, 20, 18, 00));

        assertNotNull("No list of events retrieved", calendarEventsForDateTime);
        assertEquals("Not the correct number of events retrieved", 2, calendarEventsForDateTime.size());
    }
}

SQL-Script

INSERT INTO CONCRETEEVENT (ID, CAPTION, DESCRIPTION, STARTDATE, ENDDATE) values (1, 'TestEvent1', 'Test Description 1', PARSEDATETIME('2016-06-24 18:00', 'yyyy-MM-dd hh:mm'), PARSEDATETIME('2016-06-24 20:00', 'yyyy-MM-dd hh:mm'));

INSERT INTO CONCRETEEVENT (ID, CAPTION, DESCRIPTION, STARTDATE, ENDDATE) values (2, 'TestEvent2', 'Test Description 2', PARSEDATETIME('2016-06-24 18:15', 'yyyy-MM-dd hh:mm'), PARSEDATETIME('2016-06-24 20:15', 'yyyy-MM-dd hh:mm'));

Answer 1

I have found my error.

In the class HibernateConfiguration i was overwriting the transactionManager. This was taken from a tutorial and seems to be unnecessary.

So the bean transactionManager has been removed from the class.

Also the annotations @EnableJpaRepositories("api") , @EnableTransactionManagement and the bean entityManagerFactory could be removed.

Answer 2

Configure H2 database
Open application.properties file, add configurations:

spring.h2.console.enabled=true  
spring.h2.console.path=/h2_console  
spring.datasource.url=jdbc:h2:file:~/h2/testdb  
spring.datasource.username=sa  
spring.datasource.password=  
spring.datasource.driverClassName=org.h2.Driver  
spring.jpa.hibernate.ddl-auto = update  
spring.jpa.show-sql=true
