Spring Data Neo4j InvalidDataAccessapiUSAGEException：事务不是该线程的当前事务

Question

@Configuration
@EnableWebMvc
@ComponentScan({"eu.bm"})
@EnableNeo4jRepositories("eu.bm.repository")
@EnableTransactionManagement
public class bmConfiguration extends WebMvcConfigurerAdapter {

@Bean
public OpenSessionInViewInterceptor openSessionInViewInterceptor() {
    OpenSessionInViewInterceptor openSessionInViewInterceptor =
            new OpenSessionInViewInterceptor();
    openSessionInViewInterceptor.setSessionFactory(sessionFactory());
    return openSessionInViewInterceptor;
}

public void addInterceptors(InterceptorRegistry registry) {
    registry.addWebRequestInterceptor(openSessionInViewInterceptor());
}

@Bean
public static SessionFactory sessionFactory() {
    return new SessionFactory("eu.bm.domain");
}

@Bean
public Neo4jTransactionManager transactionManager() throws Exception {
    return new Neo4jTransactionManager(sessionFactory());
}

@Repository
public interface UserRepository extends GraphRepository<User>{

@Query("MATCH (user:User) where user.name={0} return user ")
User findUser(String username);

@Query("MATCH (user:User) where user.name={0} delete user ")
User deleteUser(String username);

@Query("match (user:User) delete user")
User deleteAllUsers();

}

@Component
public interface UserManagementService {

List<User> listAll();

User save(User user);

User findUser(String username);
}

@Service
@Transactional
public class UserManagementServiceImpl implements UserManagementService {

private UserRepository userRepository;

@Autowired
public UserManagementServiceImpl(UserRepository userRepository) {this.userRepository = userRepository;}

@Override
public List<User> listAll() {
    List<User> users = new ArrayList<>();
    userRepository.findAll().forEach(users::add);
    return users;
}

@Override
public User save(User user) {
    userRepository.save(user);
    return user;
}

@Override
public User findUser(String username) {
    return userRepository.findUser(username);
}

然后执行一个简单的写-读测试，如下所示：

@RunWith(SpringJUnit4ClassRunner.class)
@SpringBootTest
public class DatabaseConnectionTest {

// User 1
private static final String UNAME1 = "Paul";
private static final String EMAIL1 = "[e-mail]";
private static final String PASSWORD1 = "p@ss";
private static final String USERNAME1 = "paul";

@Autowired
private UserRepository userRepository;

@Before
public void setUp() throws Exception {

    // Clear database before adding new user
    userRepository.deleteAllUsers();

    // Creating user
    User user = new User(UNAME1, USERNAME1, PASSWORD1, EMAIL1);
    userRepository.save(user);
}

@Test
public void testPersistence() {

    Assert.assertEquals(UNAME1, userRepository.findUser(UNAME1).getName());
    Assert.assertEquals(USERNAME1, userRepository.findUser(UNAME1).getUsername());

}

上面的结果就是这个错误：

2017-08-16 14:59:38.990信息6496---[main]E.B.repository.DatabaseConnectionTest：7.131秒内启动DatabaseConnectionTest（JVM运行于8.331）2017-08-16 14:59:39.872信息6496---[main]o.n.o.drivers.http.request.httprequest:Thread:1，URL:http://localhost:7474/db/data/transaction/39，请求：{“语句”：[{“语句”：“Unwind{rows}as row CREATE(n:user f,ID(n)为ID,row.type为type”,“parameters”：{“rows”：[{“noderef”：-1821370276,“type”：“node”,“props”：{“password”：“p@ss”,“name”：“paul”,“email”：“[e-mail]”,“username”：“paul”}}]},“resultdatacontents”：[“row”],“includestats”：false}]}2017-08-16 14:59:40.358错误6496---[main]

• 为什么userrepository.save（user）在数据库中创建记录但抛出异常？
• “此线程的事务不是当前的”是什么意思？
• 为什么userrepository.save（user）最终失败，但userrepository.deleteallusers（）工作？

Answer 1

您的SessionFactorybean不应声明为static:

@Bean
public static SessionFactory sessionFactory() {
    return new SessionFactory("eu.bm.domain");
}

应该是

@Bean
public SessionFactory sessionFactory() {
    return new SessionFactory("eu.bm.domain");
}
