Question

我必须在我的mule流中实现支持XA事务的jdbc连接池。使用spring，我已经实现了数据源，如下所示

但我面临以下例外情况。如何使用spring实现XAconnection以上池的支持？

ERROR 2015-12-17 15:51:37,626 [[apikey_load_phase3].Mule.02] org.mule.retry.notifiers.ConnectNotifier: Failed to connect/reconnect: EEJdbcConnector

  numberOfConcurrentTransactedReceivers=4
  createMultipleTransactedReceivers=false
  connected=false
  supportedProtocols=[jdbc]
  serviceOverrides=<none>
}
 *Root Exception was: Connection from pool does not implement javax.sql.XAConnection(SQL Code: 0, SQL State: + null). Type: class java.sql.SQLException*

您需要替换：

com.mysql.jdbc.Driver

使用：

com.mysql.jdbc.jdbc2.optional.MysqlXADataSource

如何使用弹簧在tomcat连接池中实现XA连接支持？
