</beans>

 使用的时候这样写就ok了：

 

@PersistenceContext(unitName = "first") 
    private EntityManager em ;
	
	@Autowired
	private SessionFactory thirdSessionFactory;

 对指定的业务方法加上@Transactional就可以实现事物的管理。

下面是hibernate4的写法atomikos-hibernate4.xml：

hibernate4多了一个类AtomikosJtaPlatform：

 

package org.lmc.platform.jta;

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

import org.hibernate.engine.transaction.jta.platform.internal.AbstractJtaPlatform;

public class AtomikosJtaPlatform extends AbstractJtaPlatform {
	private static final long serialVersionUID = 4896569440655581002L;
	private static TransactionManager transactionManager;
	private static UserTransaction userTransaction;
	
	@Override
	protected TransactionManager locateTransactionManager() {
		return AtomikosJtaPlatform.transactionManager;
	}

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

	public void setTransactionManager(TransactionManager transactionManager) {
		AtomikosJtaPlatform.transactionManager = transactionManager;
	}

	public void setUserTransaction(UserTransaction userTransaction) {
		AtomikosJtaPlatform.userTransaction = userTransaction;
	}

	
}

 

 

oracle记着要授权，并且使用11的驱动包，jdbc注意连接的配置，

以sysdba登录数据库，给相应地用户赋予以下权限：

  • grant select on sys.dba_pending_transactions to <当前数据库用户>;
  • grant select on sys.pending_trans$ to <当前数据库用户>;
  • grant select on sys.dba_2pc_pending to <当前数据库用户>;
  • grant execute on sys.dbms_system to <当前数据库用户>;

mysql注意使用5以上，加上pinGlobalTxToPhysicalConnection参数。

你好，我看了你的博客，我这完全从你那上面copy下来的代码，一开始是提示找不到META-INF/persistence.xml这个文件，后来我把你的代码classpath:META-INF/persistence.xml改成classpath*:META-INF/persistence.xml就没这个提示了，但再重新启动就提示No persistence unit with name 'second' found，能帮我看一下是啥问题不？

META-INF/persistence.xml和web.xml的代码能贴出来不？我按你这个配置走不通呀，hibernate4的，能加扣扣聊一下不？扣扣407073846

persistence.xml已经贴出来了。web.xml没有
