"TransactionRequiredException:没有正在进行的事务“，即使应用了事务拦截器- hibernate-5和spring-4.3

Question

即使在使用事务拦截器的情况下，我也要面对这个TransactionRequiredException：

下面是我使用的代码：

Hibernate-5.2 (hibernate-entitymanager-5.1, hibernate-commons-annotations-5.0.1)
Spring-4.3.3 - (tried 4.3.2 as well, same error)

我的dispatcher -servlet.xml是空的，所有的spring配置都在applicationContext.xml中：

<context:annotation-config />
<context:component-scan base-package="my.pkg.controller, my.pkg.entity"></context:component-scan>
<mvc:annotation-driven enable-matrix-variables="true" content-negotiation-manager="contentNegotiationManager" />
<import resource="db-config.xml" />

db-config.xml包含：

<bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    <property name="dataSource" ref="dataSource"></property>
    <property name="mappingResources">
        <list>
            <value>.......hbm.xml</value>
        </list>
    </property>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.connection.autocommit">false</prop> 
            <prop key="current_session_context_class">thread</prop >
        </props>
    </property>
</bean>

<bean id="dataSource" class="org.apache.commons.dbcp2.BasicDataSource" destroy-method="close">
    .......
</bean>

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

<tx:advice id="transactionalAdvice" transaction-manager="transactionManager">
    <tx:attributes> 
        <tx:method name="get*" read-only="true"/>
        <tx:method name="find*" read-only="true"/>
        <tx:method name="*" />  
    </tx:attributes>
</tx:advice>
<aop:config>
    <!-- applying this aop on other job classes -->
</aop:config>

<tx:advice id="traxSupportedAdvice" transaction-manager="transactionManager">
    <tx:attributes>
        <tx:method name="*" propagation="SUPPORTS" />
    </tx:attributes>
</tx:advice>
<aop:config>
    <aop:advisor pointcut="execution(* my.pkg.entity.*Home.*(..))" advice-ref="traxSupportedAdvice" />
</aop:config>

我的my.pkg.entity.impl.*Impl类从my.pkg.entity扩展而来。*Home类(我正在使用jboss工具自动生成和Home类)，所有*Impl类(不是*Home类)也都用@Transactional注释。*主页在aop中用传播“支持”建议指示。LoginController.setClient()用@Transactional注解。

我不知道我做错了什么或遗漏了什么。我确实试着在SOF和google上搜索，但找不到可以在这里应用的。

如果需要任何其他信息，请让我知道。如果我在这里偏离了任何std/首选配置方法，也请让我知道。

谢谢你的帮助。

Answer 1

未应用LoginController.setClient的@Transactional批注。因为它是一个bean内部调用。您可以在Stacktrace中看到这一点

at my.pkg.controller.LoginController.setClient(LoginController.java:243)
at my.pkg.controller.LoginController.setupUserSession(LoginController.java:185)
at my.pkg.controller.LoginController.login(LoginController.java:121)

您也许可以从login方法开始。但我没有足够的细节可以告诉你。
