Question

当我在我的服务上运行JUnit测试时，它会成功地将新实体添加到我的数据库中，但是当我从Controller调用该服务时，它不会保存到数据库中。我错过了什么？

jpa.xml

<jpa:repositories base-package="com.mypackage.commons" />

<bean id="jpaVendorAdapter"
    class="org.springframework.orm.jpa.vendor.HibernateJpaVendorAdapter">
    <property name="showSql" value="true" />
    <property name="generateDdl" value="true" />
    <property name="database" value="MYSQL" />
</bean>

<bean id="entityManagerFactory"
    class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="jdbcDataSource" />
    <property name="jpaVendorAdapter" ref="jpaVendorAdapter" />
    <!-- spring based scanning for entity classes -->
    <property name="packagesToScan" value="com.mypackage" />
</bean>

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager" />

<tx:annotation-driven />

UserService

@Service
public class RepositoryUserService implements UserService {

    @Resource
    private UserRepository userRepository;

    @Transactional
    @Override
    public User create(User user) {
        User newUser = userRepository.save(user);
        return newUser;
    }
}

myController的

@Controller
@Path("/users")
public class MyAPI {

    @Autowired
    private UserService userService;

    @POST
    @Path("/add")
    @Consumes(MediaType.APPLICATION_JSON)
    @Transactional
    public Response addUser(User newUser) {
         userService.create(newUser);
    }
}

为事务设置entityManager：

<bean id="transactionManager" class="org.springframework.orm.jpa.JpaTransactionManager">
        <property name="entityManagerFactory" ref="entityManagerFactory" />
    </bean>

以这种方式驱动注释：

<tx:annotation-driven transaction-manager="transactionManager"
    proxy-target-class="true" />

尝试从控制器中删除@Transactional，定义传播并刷新会话

  @Transactional(propagation= Propagation.REQUIRED)
    @Override
    public User create(User user) {
       try{
        return userRepository.saveAndFlush(user);
        } catch(DataIntegrityViolationException e){
         // handle the exception in here to find out what  is wrong            
        }
    }

Spring JPA没有存储到数据库
