春季+ Hibernate4 + JTA + JBossTS

Question

为了使用独立的Java应用程序设置JTA，我已经进行了超过2天的努力，但是不幸的是id无法正常工作，我希望能获得一些帮助。

一般信息：

• 春季版：3.2.3
• 休眠版本：4.2.3
• Jbossts版本：4.17.7，我仅将narayana-jta.jar添加到我的类路径中。

Spring配置文件：

<bean class="com.arjuna.ats.jta.TransactionManager" factory-method="transactionManager" id="arjunaTransactionManager" />
<bean class="com.arjuna.ats.jta.UserTransaction" factory-method="userTransaction" id="arjunaUserTransaction" />

<bean class="org.springframework.transaction.jta.JtaTransactionManager" id="transactionManager">
    <property name="transactionManager">
        <ref bean="arjunaTransactionManager" />
    </property>
    <property name="userTransaction">
        <ref bean="arjunaUserTransaction" />
    </property>
</bean>

<tx:annotation-driven />

休眠配置文件：

<?xml version='1.0' encoding='utf-8'?>
<!DOCTYPE hibernate-configuration PUBLIC
  "-//Hibernate/Hibernate Configuration DTD//EN"
  "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd">
<hibernate-configuration>
    <session-factory>
        <!-- Database connection settings -->
        <property name="connection.driver_class">com.microsoft.sqlserver.jdbc.SQLServerDriver</property>
        <property name="connection.url">jdbc:sqlserver://localhost:1433;databaseName=TestDB</property>
        <property name="connection.username">user</property>
        <property name="connection.password">password</property>

        <!-- JDBC connection pool (use the built-in) -->
        <property name="connection.pool_size">1</property>

        <!-- SQL dialect -->
        <property name="dialect">org.hibernate.dialect.SQLServerDialect</property>

        <!-- Enable Hibernate's automatic session context management -->
        <property name="current_session_context_class">jta</property>

        <!-- Disable the second-level cache -->
        <property name="cache.provider_class">org.hibernate.cache.internal.NoCacheProvider</property>

        <!-- Echo all executed SQL to stdout -->
        <property name="show_sql">true</property>

        <property name="transaction.factory_class">org.hibernate.transaction.JTATransactionFactory</property>
        <property name="transaction.jta.platform">org.hibernate.service.jta.platform.internal.JBossStandAloneJtaPlatform</property>
    </session-factory>
</hibernate-configuration>

在这一点上，我需要创建休眠会话工厂，并且要以编程方式创建它，为此，我使用了以下代码片段，在其中创建了一个Spring LocalSessionFactoryBean传递给它的休眠配置资源，并使用它从中检索SessionFactory。 .getObject（）方法。

这段代码可以正常工作并创建一个SessionFactory对象，该对象将在下一个代码段中使用。

LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
JtaTransactionManager trxManager = applicationContext.getBean(JtaTransactionManager.class);
sessionFactoryBean.setJtaTransactionManager(trxManager);
sessionFactoryBean.setConfigLocation(resource);
sessionFactoryBean.afterPropertiesSet();
SessionFactory sessionFactory = sessionFactoryBean.getObject();

之后，我有一个Service类，它可以插入表中：

package com.core.service;

import org.hibernate.Query;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Component;
import org.springframework.transaction.annotation.Transactional;

@Component
@Scope("prototype")
public class TestService {

    @Transactional
    public void testTrx() throws Exception {
        SessionFactory sessionFactory = // retrieve session factory created before

        Session session = sessionFactory.getCurrentSession();
        Query query = session.createSQLQuery("insert into TABLE1 (col1, col2) values (:v1, :v2)");
        query.setParameter("v1", "value1");
        query.setParameter("v2", "value2");

        query.executeUpdate();
    }
}

最后是一个JUnit测试，该测试加载Spring上下文并初始化所有内容，然后执行以下行：

@Test
public void testTransactionRollback() throws Exception {
    TestService testService = applicationContext.getBean(TestService.class);
    testService.testTrx();
}

问题：执行JUnit测试时，出现绿色条，并且看到在表中插入一条SQL语句，并且看到事务已打开并提交，但是如果我去数据库，我不会看不到插入的行。

我的结论：我试图设置休眠配置connection.autocommit = true，并且在数据库中正确创建了该行，因此我假设是的，是打开和关闭了JTA事务，但是休眠会话工厂未使用它们，而是使用了它自己的。 我是否缺少某些配置？

Answer 1

我认为这是因为您的数据库连接未与JTA绑定。 您仅使JTA同步了休眠。 您应该使用com.arjuna.ats.jdbc.TransactionalDriver来创建连接：

TransactionalDriver arjunaJDBC2Driver = new TransactionalDriver();
Connection connection = arjunaJDBC2Driver.connect(url, dbProps);

春天的例子：

 <bean id="dataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
  <property name="driverClassName">
   <value>com.arjuna.ats.jdbc.TransactionalDriver</value>
  </property>
  <property name="url" value="jdbc:arjuna:mysql://host:3306/dbName"/>
  <property name="connectionProperties">
    <ref bean="dsProps"/>
  </property>
 </bean>

希望这个帮助
