我从 Hibernate 4.2 切换到 Hibernate 4.3，我的项目不再工作了。我得到一个

HibernateException：无法定位当前的 JTA 事务

当我做

Session s = sessionFactory.getCurrentSession();

我已经意识到 org.hibernate.transaction.TransactionManagerLookup 不再存在。它在 Hibernate 4.3 中被删除。我应该如何更改我当前的配置？

<hibernate-configuration>
<session-factory>
    <property name="connection.datasource">testDS</property>

    <property name="current_session_context_class">jta</property>
    <property name="transaction.manager_lookup_class">com.atomikos.icatch.jta.hibernate3.TransactionManagerLookup</property>
    <property name="transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</property>
    <property name="connection.release_mode">auto</property>
    <property name="cache.provider_class">org.hibernate.cache.NoCacheProvider</property>

    <property name="hibernate.hbm2ddl.auto">create-drop</property>
    <property name="hibernate.show_sql">true</property>
    <mapping class="test.entities.Person" />
    <mapping class="test.entities.CreditCard" />
    <mapping class="test.entities.ExampleRevEntity" />
</session-factory>

在 Hibernate 4.3 中，长期弃用的 TransactionManagerLookup 被删除。现在 JTA 提供者必须实现 org.hibernate.engine.transaction.jta.platform.spi.JtaPlatform。JTA Platform 的抽象实现已经在 Hibernate 中可用，即 org.hibernate.engine.transaction.jta.platform.internal.AbstractJtaPlatform。使用它为 Atomikos 编写 JTA 平台非常简单：

package test;

import javax.transaction.TransactionManager;
import javax.transaction.UserTransaction;
import org.hibernate.engine.transaction.jta.platform.internal.AbstractJtaPlatform;
import com.atomikos.icatch.jta.UserTransactionManager;

public class AtomikosJtaPlatform extends AbstractJtaPlatform {

  private static final long serialVersionUID = 1L;
  private UserTransactionManager utm;

  public AtomikosJtaPlatform() {
    utm = new UserTransactionManager();
  }

  @Override
  protected TransactionManager locateTransactionManager() {
    return utm;
  }

  @Override
  protected UserTransaction locateUserTransaction() {
    return utm;
  }
}

此外，必须将平台实现类的名称添加到休眠配置中：

<property name="hibernate.transaction.jta.platform">test.AtomikosJtaPlatform</property>

要将 Hibernate JTA Platform 与 Spring 一起使用，请编写并编译此代码

package my.domain.spring.hibernate.jta;

import javax.transaction.TransactionManager;
import javax.transaction.UserTransaction;

import org.hibernate.engine.transaction.jta.platform.internal.AbstractJtaPlatform;
import org.springframework.transaction.jta.JtaTransactionManager;
import org.springframework.util.Assert;

@SuppressWarnings("serial")
public class SpringJtaPlatformAdapter extends AbstractJtaPlatform {

    private static TransactionManager sTransactionManager;
    private static UserTransaction sUserTransaction;


    @Override
    protected TransactionManager locateTransactionManager() {
        Assert.notNull(sTransactionManager, "TransactionManager has not been setted");
        return sTransactionManager;
    }


    @Override
    protected UserTransaction locateUserTransaction() {
        Assert.notNull(sUserTransaction, "UserTransaction has not been setted");
        return sUserTransaction;
    }


    public void setJtaTransactionManager(JtaTransactionManager jtaTransactionManager) {
        sTransactionManager = jtaTransactionManager.getTransactionManager();
        sUserTransaction = jtaTransactionManager.getUserTransaction();
    }


    public void setTransactionManager(TransactionManager transactionManager) {
        sTransactionManager = transactionManager;
    }


    public void setUserTransaction(UserTransaction userTransaction) {
        sUserTransaction = userTransaction;
    }

}

添加到您的弹簧配置中

  <bean id="txObjcoreManager" class="org.springframework.transaction.jta.JtaTransactionManager">
        <property name="transactionManager">
            <bean class="com.atomikos.icatch.jta.UserTransactionManager" init-method="init" destroy-method="close">
                <property name="forceShutdown" value="true" />
            </bean>
        </property>
        <property name="userTransaction">
            <bean class="com.atomikos.icatch.jta.UserTransactionImp">
                <property name="transactionTimeout" value="300" />
            </bean>
        </property>
    </bean>

    <bean id="springJtaPlatformAdapter" class="my.domain.spring.hibernate.jta.SpringJtaPlatformAdapter">
        <property name="jtaTransactionManager" ref="txObjcoreManager" />
    </bean>

不要忘记添加依赖项

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean"
        depends-on="springJtaPlatformAdapter">

最后改变一个像这样的休眠配置 hibernate.transaction.jta.platform=my.domain.spring.hibernate.jta.SpringJtaPlatformAdapter

给 Spring 用户的一些提示——如果你使用工厂 bean 设置东西，只需使用这个实现：

public class AtomikosPlatform extends AbstractJtaPlatform {

  private static final long serialVersionUID = -1L;

  @Override
  protected TransactionManager locateTransactionManager() {
    return new J2eeTransactionManager();
  }

  @Override
  protected UserTransaction locateUserTransaction() {
    return new J2eeUserTransaction();
  }

}

您可以尝试将 org.springframework.orm.hibernate4.LocalSessionFactoryBean 的 jtaTransactionManager 属性设置为 Spring 的 JtaTransactionManager 吗？我有类似的问题，但通过这个解决了。顺便说一句，HibernateTemplate 又回到了 Spring 4.0.1。虽然不推荐，但我喜欢用它。它帮助处理了很多事情。（我使用的是 Spring 4.0.5 + Hibernate 4.3.5 + Atomikos 3.9.3）

<bean id="atomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager" init-method="init" destroy-method="close" depends-on="userTransactionService">
   <property name="forceShutdown" value="true" />
</bean>

<bean id="atomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp" depends-on="userTransactionService">
   <property name="transactionTimeout" value="180" />
</bean>

<bean id="JtaTransactionManager" class="org.springframework.transaction.jta.JtaTransactionManager">
   <property name="transactionManager" ref="atomikosTransactionManager" />
   <property name="userTransaction" ref="atomikosUserTransaction" />
   <property name="allowCustomIsolationLevels" value="true"></property>
</bean>

<bean id="rentSessionFactory" class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">
    <property name="dataSource"><ref bean="rentXADataSource" /></property>
    <property name="mappingLocations" value="classpath:com/kj/model/web/*.hbm.xml"/>
    <property name="hibernateProperties">
        <props>
            <prop key="hibernate.dialect">org.hibernate.dialect.SQLServerDialect</prop>
            <prop key="hibernate.cache.region.factory_class">org.hibernate.cache.ehcache.EhCacheRegionFactory</prop>
            <prop key="hibernate.show_sql">false</prop>
            <prop key="hibernate.transaction.factory_class">org.hibernate.transaction.CMTTransactionFactory</prop>          
            <prop key="hibernate.cache.use_query_cache">true</prop> 
            <prop key="hibernate.cache.use_second_level_cache">true</prop>
            <prop key="hibernate.format_sql">false</prop>
            <prop key="hibernate.bytecode.use_reflection_optimizer">true</prop>
        </props>
    </property>
    <property name="jtaTransactionManager" ref="JtaTransactionManager"></property>
</bean>

以下是与 Spring 配置一起使用的替代方法。这与 Anton 的方法不同，因为它不依赖实例方法写入静态字段（这通常被认为是不好的做法）。

@SuppressWarnings("serial")
public class AtomikosJtaPlatform extends AbstractJtaPlatform {

    private static TransactionManager transactionManager;
    private static UserTransaction userTransaction;

    public static void factoryInit(TransactionManager transactionManager, UserTransaction userTransaction) {
        AtomikosJtaPlatform.transactionManager = transactionManager;
        AtomikosJtaPlatform.userTransaction = userTransaction;
    }

    @Override
    protected TransactionManager locateTransactionManager() {
        return transactionManager;
    }

    @Override
    protected UserTransaction locateUserTransaction() {
        return userTransaction;
    }

}

然后在 Spring 配置中：

    <bean id="AtomikosTransactionManager" class="com.atomikos.icatch.jta.UserTransactionManager" init-method="init"
        destroy-method="close">
        <property name="startupTransactionService" value="false" />
        <property name="forceShutdown" value="false" />
    </bean>

    <bean id="AtomikosUserTransaction" class="com.atomikos.icatch.jta.UserTransactionImp">
        <property name="transactionTimeout" value="300" />
    </bean>

    <!-- AtomikosJtaPlatform is created by Hibernate using reflection. This ensures it uses our Spring configured beans --> 
    <bean id="JtaPlatformInitializer" class="org.springframework.beans.factory.config.MethodInvokingBean">
        <property name="targetClass" value="com.mycompany.a.b.AtomikosJtaPlatform" />
        <property name="targetMethod" value="factoryInit" />
        <property name="arguments">
            <list>
                <ref bean="AtomikosTransactionManager" />
                <ref bean="AtomikosUserTransaction" />
            </list>
        </property>
    </bean>

<bean id="emf" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean" depends-on="JtaPlatformInitializer">
        <property name="jpaProperties">
            <props>
                <prop key="hibernate.transaction.jta.platform">com.mycompnay.a.b.AtomikosJtaPlatform</prop>
