问题描述
我努力使声明式事务的工作。
i try to make declarative transaction work.
这是我的spring.xml文件：
This is my spring.xml file:
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:tx="http://www.springframework.org/schema/tx"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation=
"http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property name="url" value="jdbc:h2:tcp://my/db/path" />
<property name="username" value="username" />
<property name="password" value="password" />
</bean>
<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource" ref="dataSource" />
<property name="packagesToScan" value="data" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.H2Dialect</prop>
<prop key="hibernate.current_session_context_class">thread</prop>
<prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.hbm2ddl.auto">update</prop>
</props>
</property>
</bean>
<context:component-scan base-package="test" />
<tx:annotation-driven/>
<bean id="transactionManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory" />
</bean>
</beans>
这是我的控制器实现：
And this is my controller implementation:
//file TestController.java
public interface TestController {
public List<Test> findAll();
}
//file TestControllerImp.java
@Controller
public class TestControllerImp implements TestController{
@Autowired
private SessionFactory sessionFactory;
/**
* @return the sessionFactory
*/
public SessionFactory getSessionFactory() {
return sessionFactory;
}
/**
* @param sessionFactory the sessionFactory to set
*/
public void setSessionFactory(SessionFactory sessionFactory) {
this.sessionFactory=sessionFactory;
}
@Transactional
public List<Test> findAll() {
return sessionFactory.getCurrentSession().createQuery("from Test").list();
}
}
两者都在里面的包叫做测试。
Both are inside package called test.
这是我的尝试：
TestController tc=context.getBean(TestController.class);
List<Test> list=tc.findAll();
但是，这引发异常：
But this throw an exception:
org.hibernate.HibernateException：的createQuery是无效的无活动事务
为什么transactionManager在不工作？我希望与@Transactional注释的所有交易将被Spring框架进行管理。
我能做些什么？
Why transactionManager doesn't work? I hope with @Transactional annotation all transactions will be managed by spring framework.What can i do?
谢谢大家。
推荐答案
删除以下行，当交易由Spring管理是不需要的：
Remove the following lines, they are not needed when transactions are managed by Spring:
<prop key="hibernate.current_session_context_class">thread</prop>
<prop key="hibernate.transaction.factory_class">org.hibernate.transaction.JDBCTransactionFactory</prop>
其实，设置的hibernate.current_session_context_class 有效地禁止Spring的事务管理，看<$c$c>AbstractSessionFactoryBean.setExposeTransactionAwareSessionFactory() javadoc的：
Actually, setting hibernate.current_session_context_class effectively disables Spring transaction management, see AbstractSessionFactoryBean.setExposeTransactionAwareSessionFactory() javadoc:
关闭这个标志，露出平原
Hibernate的SessionFactory与
Hibernate的默认
的getCurrentSession（）的行为，
支持普通的JTA同步
只要。或者，干脆重写
相应的Hibernate属性
的hibernate.current_session_context_class。
