我用SpringBoot, Spring Test DBUnit。我写了一个测试：

ShortenerAppTest：

@TestPropertySource(locations = "classpath:application-test.properties")
@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest(classes = ShortenerApp.class)
@WebAppConfiguration
public class ShortenerAppTest {
   @Test
   public void contextLoads() {
   }
}

repositories/AbstractRepositoryTest：

@TestPropertySource(locations = "classpath:application-test.properties")
@TestExecutionListeners(DbUnitTestExecutionListener.class)
@SpringBootTest(classes = ShortenerApp.class)
@DirtiesContext
abstract class AbstractRepositoryTest extends AbstractTransactionalJUnit4SpringContextTests {
}

repositories/LinkRepositoryTest：

@DatabaseSetup(LinkRepositoryTest.DATASET)
@DatabaseTearDown(type = DatabaseOperation.DELETE_ALL, value = LinkRepositoryTest.DATASET)
public class LinkRepositoryTest {
   final static String DATASET = "classpath:datasets/link-table.xml";
   private final static Long LINK_1_ID = 100500L;
   private final static String LINK_1_TEXT = "http://www.www.ya.ru";

@Autowired
LinkRepository repository;

@Test
public void findOneExisting() {
    System.out.println(DATASET);
    Optional<Link> got = repository.findOne(LINK_1_ID);
    assertThat(got.isPresent(), equalTo(true));
    Link linkFromDb = got.get();
    Link link = new Link();
    link.setId(LINK_1_ID);
    link.setUrl(LINK_1_TEXT);
    assertThat(linkFromDb, equalTo(link));
}
}

并且dataset：

<?xml version="1.0" encoding="UTF-8" ?>
<dataset>
    <links id="100500" url="http://www.ya.ru"/>
    <links id="100501" url="http://www.mail.ru"/>
    <links id="100502" url="http://www.google.com"/>
</dataset>

application-test.properties：

spring.datasource.url=jdbc:h2:mem:test
spring.datasource.username=sa
spring.datasource.password=sa
spring.datasource.driverClassName=org.h2.Driver
spring.jpa.show-sql=true
spring.jpa.hibernate.ddl-auto=create-drop

但是，当我尝试运行测试时，我有java.lang.NullPointerException. 我猜这是因为数据库没有必要的记录。

从日志可以看出，他是在尝试使用真实的数据库，而不是测试库。出于某种原因，它没有读取我的测试配置。 在此处输入图像描述 我究竟做错了什么？

更新：

当我这样写时ShortenerAppTest：

@DatabaseSetup("/datasets/link-table.xml")
@TestExecutionListeners({DependencyInjectionTestExecutionListener.class,
    DirtiesContextTestExecutionListener.class,
    TransactionalTestExecutionListener.class,
    DbUnitTestExecutionListener.class})
public class ShortenerAppTest {
@Autowired
LinkRepository repository;
@Test
public void contextLoads() {
   Optional<Link> got = repository.findOne(100500L);
    System.out.println(got);
}
}

它的工作，但我仍然得到我的错误LinkRepositoryTest
