Hibernate Spring事务处理没有事务处理正在进行中

Question

我试图让spring处理spring管理事务。无论我做什么，我都会得到'没有交易正在进行'的例外情况。我不明白的一件事是：

如果我不叫我@Transactional方法sessionFactory.getCurrentSession()，一切顺利，我可以看到被称为HibernateTransactionManager交易生命周期方法 - doGetTransaction(...), doCommit(...)等，并不会引发错误。

当我在我的方法添加sessionFactory.getCurrentSession()我仍然看到doGetTransaction()（明显），但只要getCurrentSession()叫我开始看到doRollback()，最后我得到“没有交易正在进行中”的异常。我已经花了整整一天的时间，希望有人帮助。尝试改变事务范围，XML配置，基本上我能想到的一切。它采用了最新的弹簧和休眠（4.3.3和5.2.3分别）版本

的applicationContext.xml：

<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource"> 
    <property name="driverClassName" value="com.mysql.jdbc.Driver"/> 
    <property name="url" value="jdbc:mysql://localhost:3306/trainings"/> 
    <property name="password" value="xxx"/> 
    <property name="username" value="xxx"/> 
</bean> 

<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean"> 
    <property name="hibernateProperties"> 
     <props> 
      <prop key="hibernate.show_sql">true</prop> 
      <prop key="hibernate.dialect">org.hibernate.dialect.MySQLDialect</prop> 
     </props> 
    </property> 
    <property name="dataSource" ref="dataSource"/> 
</bean> 

<bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager" > 
    <property name="sessionFactory" ref="sessionFactory"/> 
    <property name="dataSource" ref="dataSource" /> 
</bean> 

<context:annotation-config/> 

<context:component-scan base-package="webtrainings.beans"/> 

<tx:annotation-driven transaction-manager="transactionManager" /> 

GenericDAO.java：

@Repository("genericDao") 
@Scope(value = "singleton") 
public class GenericDAO<T> { 

    @Autowired 
    private SessionFactory sessionFactory; 

    @Autowired 
    private ApplicationContext appContext; 

    public void getAll(Class<T> clazz) { 
     factory.getCurrentSession(); 
    } 
} 

MyService.java：

@Service("myService") 
@Transactional 
public class MyService { 

    @Autowired 
    GenericDAO genericDAO; 

    @Transactional 
    public void hehe() { 
     genericDAO.getAll(Training.class); 
    } 
} 

HelloController.java：

@Controller 
@RequestMapping(value = "/welcome") 
public class HelloController { 

    @Autowired 
    MyService myService; 

    @Autowired 
    ApplicationContext applicationContext; 

    @RequestMapping(method = RequestMethod.GET) 
    public ModelAndView handleRequestInternal(HttpServletRequest request, 
               HttpServletResponse response) throws Exception { 
     ModelAndView model = new ModelAndView("hello"); 
     model.addObject("msg", "hello world"); 
     myService.hehe(); 

     return model; 
    } 
} 

弹簧servlet.xml中（MVC）：

<context:component-scan base-package="webtrainings.utils"/> 

<bean id="viewResolver" 
      class="org.springframework.web.servlet.view.InternalResourceViewResolver" > 
     <property name="prefix"> 
      <value>/WEB-INF/jsp/</value> 
     </property> 
     <property name="suffix"> 
      <value>.jsp</value> 
     </property> 
</bean>

显然的问题是在使用Java DCEVM与HotswapAgent。当我从tomcat运行配置中删除-XXaltjvm=dcevm -javaagent:C:\hotswap-agent.jar时，一切都按预期工作。我想这是使用“hacky”软件的副作用之一。我在这些事情上的知识太少，甚至无法猜测实际问题是什么。
