Narayana事务回滚流程

Narayana 事务回滚流程

当用户手动调用 connection.rollback() 回滚当前全局事务时，会走如下流程。

总体流程

遍历每个 resource
    执行 xa end;
    执行 xa rollback;
清理缓存

使用

TransactionManager transactionManager = jtaPropertyManager.getJTAEnvironmentBean().getTransactionManager();
// 开启事务
transactionManager.begin();
// 执行 sql 语句
// ...
// 回滚事务
transactionManager.rollback();

调用链路

    com.arjuna.ats.arjuna.coordinator.BasicAction#status
    获取当前事务状态
