我在spring-boot Web应用程序中对jpa存储库的集成测试存在问题。 对服务方法的测试失败，因为访问的存储库不会返回任何结果。但是数据库的事务应该包含数据，因为在日志显示测试的事务已经开始之后，SQL脚本会正确执行。
如果代码用作Web服务，则可以按预期访问数据，因此测试事务似乎存在问题。
有人能指出我正确的方向来解决这个问题吗？
PS：@Data来自https://projectlombok.org/，它创建了一个完整的bean。
这是我的相应代码：
实体
@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;
}
存储库
public interface ConcreteEventRepository
extends PagingAndSortingRepository<ConcreteEvent, Long> {
}
服务
@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;
}
}
测试
@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脚本
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'));

依赖关系
答案 0 :(得分：2)
我发现了我的错误。
在班级HibernateConfiguration中，我覆盖了transactionManager。这是从教程中获取的，似乎没必要。
因此已从类中删除了bean transactionManager。
此外，还可以删除注释@EnableJpaRepositories("api")，@EnableTransactionManagement和bean entityManagerFactory。

配置H2数据库
打开application.properties文件，添加配置：
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
