java - 无法仅在 Neo4J Junit 中将事务标记为回滚

Question

我一直在尝试为 Spring data neo4j(版本 3.0.1.RELEASE) 应用程序设置我的测试框架。我正在使用纯 Java 配置来设置我的测试用例。

这是我的 TestConfig 类

@Configuration
@EnableTransactionManagement
@EnableNeo4jRepositories(basePackages = {"com.sitename.data.repository"})
@ComponentScan(basePackages = "com.sitename.data")
public class TestDataConfig extends Neo4jConfiguration {

    @Bean(destroyMethod = "shutdown")
    public GraphDatabaseService graphDatabaseService() {
        return new TestGraphDatabaseFactory().newImpermanentDatabase();
    }

    @Bean
    public Neo4jTemplate neo4jTemplate() {
        return new Neo4jTemplate(graphDatabaseService());
    }

}

这是我的测试课

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(loader = AnnotationConfigContextLoader.class)
public class TestClass {

    private UserService userService = UserService.getInstance();

    @BeforeClass
    public static void setup() {
        BaseService.configure(TestDataConfig.class);
    }

    @Before
    public void addData() {
        saveOneUser("test@email.com");
    }

    @Test
    public void testMe() {
        Assert.assertEquals(0, userService.findAll().size());
    }

    private User saveOneUser(String email) {
        try {
            User user = new User();
            user.setEmail(email);
            user.setFirstName( new Integer(new Random(new Date().getTime()).nextInt(17) + 1).toString() );
            return userService.save( user );
        } catch(Exception ex) {
            System.out.println(ex.getMessage());
        }
        return null;
    }
}

每次我运行测试时，我都会收到Failed to mark transaction as rollback only错误。

尝试添加

@Transactional

在您的测试类之上，在事务中运行您的测试。
