Java JTA、Hibernate和atomikos多个XA数据源不在SpringBoot中维护事务

我有2个

MySQL

schema和相应的

MysqlXADataSource

配置如下-

@Bean(name = "sourceDataSource")
@Primary
public DataSource dataSource() {
    MysqlXADataSource dataSource = new MysqlXADataSource();
    dataSource.setPinGlobalTxToPhysicalConnection(true);
    dataSource.setUrl(DB_URL);
    dataSource.setUser(DB_USERNAME);
    dataSource.setPassword(DB_PASSWORD);

    AtomikosDataSourceBean atomikosDataSourceBean = new AtomikosDataSourceBean();
atomikosDataSourceBean.setUniqueResourceName("SourceDB");
    atomikosDataSourceBean.setXaDataSource(dataSource);

    /*DriverManagerDataSource dataSource = new DriverManagerDataSource();
    dataSource.setDriverClassName(DB_DRIVER);
    dataSource.setUrl(DB_URL);
    dataSource.setUsername(DB_USERNAME);
    dataSource.setPassword(DB_PASSWORD);*/
    System.out.println("Creatign Source data source.");
    return atomikosDataSourceBean;
}

@Bean(name = "sourceSessionFactory")
public LocalSessionFactoryBean sessionFactory(@Qualifier("jtaTransactionManager") JtaTransactionManager jts) {
    LocalSessionFactoryBean sessionFactoryBean = new LocalSessionFactoryBean();
    sessionFactoryBean.setDataSource(dataSource());
    sessionFactoryBean.setPackagesToScan(ENTITYMANAGER_PACKAGES_TO_SCAN);
    Properties hibernateProperties = new Properties();
    hibernateProperties.put("hibernate.dialect", HIBERNATE_DIALECT);
    hibernateProperties.put("hibernate.show_sql", HIBERNATE_SHOW_SQL);
    hibernateProperties.put("hibernate.hbm2ddl.auto", HIBERNATE_HBM2DDL_AUTO);
    hibernateProperties.put("hibernate.transaction.factory_class", "org.hibernate.engine.transaction.internal.jta.CMTTransactionFactory");
    hibernateProperties.put("hibernate.transaction.coordinator_class", "jta");
    hibernateProperties.put("hibernate.transaction.jta.platform", "com.atomikos.icatch.jta.hibernate4.AtomikosPlatform");

    //hibernateProperties.put("hibernate.transaction.jta.platform", AtomikosJtaPlatform.class.getName());
    sessionFactoryBean.setJtaTransactionManager(jts);
    sessionFactoryBean.setHibernateProperties(hibernateProperties);
    System.out.println("Creatign Source Session Factory.");
    return sessionFactoryBean;
}

及

事务配置

@Bean("transactionManager")
public UserTransactionManager transactionManager(){
    UserTransactionManager userTransactionManager = new UserTransactionManager();
    return userTransactionManager;
}

@Bean("userTransaction")
public UserTransaction userTransaction(){
    J2eeUserTransaction userTransaction = new J2eeUserTransaction();
    return userTransaction;
}

@Bean("jtaTransactionManager")
public JtaTransactionManager jtaTransactionManager(@Qualifier("transactionManager") UserTransactionManager userTransactionManager, @Qualifier("userTransaction") UserTransaction userTransaction) {
    JtaTransactionManager transactionManager = new JtaTransactionManager();
    transactionManager.setTransactionManager(userTransactionManager);
    transactionManager.setUserTransaction(userTransaction);
    //transactionManager.setSessionFactory(sessionFactory().getObject());
    System.out.println("Creatign JTA Transaction Manager.");
    return transactionManager;
}

服务

@Transactional(transactionManager = "jtaTransactionManager", propagation=Propagation.REQUIRES_NEW, rollbackFor=Exception.class, timeout=500000)
public void transform() throws JobExecutionException{
    System.out.println("START == Starting Trandformation ... ");

    //Clean Up
    transformProduct.cleanUp();
    transformService.cleanUp();
    transformResources.cleanUp();

    transformResources.transform();
    transformService.transform();
    transformProduct.transform();
    LOG.info("END == Starting Transformation ... ");
    throw new JobExecutionException();
}

还有相应的子服务类

transformProduct

，

transformService

和

transformResources

，这些类使用

sessionFactory

实现的dao类。我没有提到提交或回滚。一切都应该是跨国的。但不知怎么的，它不起作用了。。代码中有错误-

XA数据源必须用

AtomikosDataSourceBean

ans返回

AtomikosDataSourceBean

reference进行包装

为AtomikosDataSourceBean分配唯一的名称

服务方法应该是事务性的（transactionManager=“jtaTransactionManager”…），提供Spring

jtaTransactionManager

JtaTransactionManager

应与

javax.transaction.UserTransaction

一起引用，并具有

com.atomikos.icatch.jta.J2eeUserTransaction

实现

JtaTransactionManager

应与

com.atomikos.icatch.jta.UserTransactionManager

实现一起引用

问题中代码的其余部分是正确的

这是对Atomikos的直接开箱即用支持

什么不起作用？还有，为什么不直接使用Atomikos的开箱即用支持呢？您正在抛出一个选中的异常，回滚只发生在

RuntimeException

s上。您的

jtaTransactionManager

应该命名为

transactionManager

，因为这是Spring期望的默认名称。如果不匹配，您需要明确告诉

@EnableTransactionManagement

使用哪个事务管理器。我认为使用了错误的事务管理器。默认情况下，

@Transactional

获得了您的UserTransactionManagerbean@M.Deinum@StanislavL我已经改变了一些返回atomikosDataSourceBean的数据源，并为它们添加了唯一的名称。我认为这就是问题所在。现在事务正在回滚，但需要验证。如我的评论中所述，将在出现任何问题时发布。添加了

@Transactional（transactionManager=“jtaTransactionManager”…）

@M.Deinum。。添加这些额外的代码解决了这个问题。谢谢你的帮助和支持。

@Transactional(transactionManager = "jtaTransactionManager", propagation=Propagation.REQUIRES_NEW, rollbackFor=Exception.class, timeout=500000)
public void transform() throws JobExecutionException{
    System.out.println("START == Starting Trandformation ... ");

    //Clean Up
    transformProduct.cleanUp();
    transformService.cleanUp();
    transformResources.cleanUp();

    transformResources.transform();
    transformService.transform();
    transformProduct.transform();
    LOG.info("END == Starting Transformation ... ");
    throw new JobExecutionException();
}
