可能是什么问题？

注意：我也试过https://docs.wso2.com/display/ESB481/Transaction+Mediator+Example有一个数据库和2个表，但是有MySQL。

在故障序列结束时标记。您的故障顺序应如下所示。

     <faultSequence>
        <property name="SET_ROLLBACK_ONLY" value="true" scope="axis2"/>
        <log level="custom">
           <property name="Transaction Action" value="Rollbacked"/>
        </log>
        <transaction action="rollback"/>
        <send/>
     </faultSequence>
