Question

我正在尝试让hibernate使用spring托管事务。无论我做什么，我总是得到“没有交易正在进行中”的例外。我唯一不明白的是：

如果我没有在我的sessionFactory.getCurrentSession()方法中调用@Transactional，一切正常，我可以看到HibernateTransactionManager调用了事务生命周期方法 - doGetTransaction(...), doCommit(...)等等。错误被抛出。

当我在方法中添加sessionFactory.getCurrentSession()时，我仍然会看到doGetTransaction()（很明显），但只要getCurrentSession()被调用，我就会开始看到doRollback()最后我得到'没有交易正在进行'的例外。我已经花了一整天时间，希望有人帮忙。尝试改变事务范围，xml配置，基本上我能想到的一切。使用最新的spring和hibernate版本（分别为4.3.3和5.2.3）

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;
    }
}

spring-servlet.xml（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>

显然问题在于将Java DCEVM与HotswapAgent一起使用。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。我对这些事情的了解太小，甚至无法猜测实际问题是什么。
