bitronix-無法找到目前的JTA交易

Question

您好我有一個使用spring和hibernate的Java web應用程序。

我有一個模型類叫做角色。對於所有的模型類有共同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); 
} 

，並擁有實現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); 
    } 
} 

我有一個控制器調用該findbyid methid和傳遞價值 - 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"); 
    } 
} 

最後我春天的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> 

I在tomcat運行此應用程序。它給出了以下錯誤。

當我打電話了roleService.findById(1);

它爲什麼發生這種事？我該如何解決？

我使用彈簧3.2.1.RELEASE，休眠4.2.0.Final，BTM 2.1.3

Answer 1

SessionFactory則是配置爲使用JtaTransactionManager中。當你這樣做時，hibernate足夠聰明，可以查看當前事務資源來查找會話。

您的彈簧配置允許您使用註釋來執行事務劃分。

您的事務管理器似乎配置正確。

所以，一切都看起來不錯。唯一缺少的部分是交易註釋！

只是在你的服務層添加@Transactional：

@Override 
@Transactional 
public Role findById(Integer id) { 
    return roleDao.findById(Role.class, id); 
} 

（你也可以把服務類此批註）
