java – bitronix-无法找到当前的JTA事务
作者：互联网
嗨,我有一个使用spring和hibernate的Java Web应用程序.
我有一个名为Role的模型类.对于所有模型类,都有常见的GenericDao.java
public interface GenericDao<T>{
public void insert(T transientInstance);
public T findById(Class<?> clazz, Serializable id);
}
GenericHibernateDao.java
@Repository
public class GenericHibernateDao<T extends Serializable>
implements GenericDao<T>{
@Resource
protected SessionFactory sessionFactory;
@Override
public void insert(T transientInstance) {
sessionFactory.getCurrentSession().persist(transientInstance);
}
@SuppressWarnings("unchecked")
@Override
public T findById(Class<?> clazz, Serializable id) {
return (T) sessionFactory.getCurrentSession().get(clazz, id);
}
}
RoleService.java
public interface RoleService {
public void insert(Role role);
public Role findById(Integer id);
}
并且有它的实现RoleServiceImpl.java
@Service
public class RoleServiceImpl implements RoleService {
@Autowired
private GenericDao<Role> roleDao;
@Override
public void insert(Role role) {
roleDao.insert(role);
}
@Override
public Role findById(Integer id) {
return roleDao.findById(Role.class, id);
}
}
我有一个控制器调用这个findbyid methid并传递一个值 – RegisterController.java
@Controller
public class UserRegisterController {
@Autowired
public RoleService roleService;
@RequestMapping(value = "/register", method = RequestMethod.POST, consumes= MediaType.APPLICATION_JSON_VALUE)
@ResponseBody
public void registerUser(@RequestBody User user)
{
Role role=new Role();
role=roleService.findById(1);
System.out.println("Saved");
}
}
最后我的spring applicationContext.xml是
<bean id="dataSource" class="bitronix.tm.resource.jdbc.PoolingDataSource"
init-method="init" destroy-method="close">
<property name="className"
value="com.mysql.jdbc.jdbc2.optional.MysqlXADataSource" />
<property name="uniqueName" value="ocr/DocumentDatabase" />
<property name="minPoolSize" value="1" />
<property name="maxPoolSize" value="5" />
<property name="automaticEnlistingEnabled" value="true" />
<property name="allowLocalTransactions" value="true" />
<property name="useTmJoin" value="true" />
<property name="shareTransactionConnections" value="true" />
<property name="driverProperties">
<props>
<prop key="url">${jdbc.url}</prop>
<prop key="user">${jdbc.username}</prop>
<prop key="password">${jdbc.password}</prop>
</props>
</property>
</bean>
<bean id="bitronixTransactionManager" factory-method="getTransactionManager"
class="bitronix.tm.TransactionManagerServices" depends-on="btmConfig, dataSource"
destroy-method="shutdown" />
<bean id="transactionManager"
class="org.springframework.transaction.jta.JtaTransactionManager">
<property name="transactionManager" ref="bitronixTransactionManager" />
<property name="userTransaction" ref="bitronixTransactionManager" />
</bean>
<tx:annotation-driven transaction-manager="transactionManager" />
<bean id="sessionFactory"
class="org.springframework.orm.hibernate4.LocalSessionFactoryBean"
destroy-method="destroy">
<property name="dataSource" ref="dataSource" />
<property name="jtaTransactionManager" ref="transactionManager"/>
<property name="configLocation" value="classpath:hibernate.cfg.xml" />
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">${hibernate.dialect}</prop>
<prop key="hibernate.query.substitutions">true 'Y', false 'N'</prop>
</props>
</property>
</bean>
我在tomcat中运行此应用程序.它给出以下错误.

当我调用roleService.findById(1)时会发生这种情况;
为什么会这样？我该如何解决？
我使用的是spring 3.2.1.RELEASE,Hibernate 4.2.0.Final,btm 2.1.3
解决方法:
sessionFactory配置为使用JtaTransactionManager.当你这样做时,hibernate足够聪明,可以查看当前的事务资源来查找会话.
您的spring配置允许您使用注释来进行事务划分.
您的事务管理器似乎已正确配置
所以,一切看起来都很好.唯一缺少的部分是交易注释！
只需在服务层添加@Transactional：
@Override
@Transactional
public Role findById(Integer id) {
return roleDao.findById(Role.class, id);
}
(您也可以将此注释放在服务类上)
