Transactions WSO2数据服务服务器分布式事务无法针对不同类型的数据库回滚

transactions wso2

Transactions WSO2数据服务服务器分布式事务无法针对不同类型的数据库回滚,transactions,wso2,distributed,rollback,wso2dss,Transactions,Wso2,Distributed,Rollback,Wso2dss,下面我将测试DSS的分布式事务没关系。由于addAccountToBank2操作中的错误，addAccountToBank1服务调用回滚。在本试验中，两个操作均涉及H2 DB 然后我做另一个测试：在这个测试中，我将其中一个H2DB替换为MySQL DB。以下是我的步骤：运行begin_boxcar操作在MySQL数据库中插入一些数据运行addToAccountBalanceInBank2操作，并为“accountId”字段指定值“1”，为“value”字段指定值“h200” 运行尾车

下面我将测试DSS的分布式事务

没关系。由于addAccountToBank2操作中的错误，addAccountToBank1服务调用回滚。在本试验中，两个操作均涉及H2 DB

然后我做另一个测试：

在这个测试中，我将其中一个H2DB替换为MySQL DB。以下是我的步骤：

运行begin_boxcar操作

在MySQL数据库中插入一些数据

运行addToAccountBalanceInBank2操作，并为“accountId”字段指定值“1”，为“value”字段指定值“h200”

运行尾车操作

运行getAccountBalanceFromBank2操作。（余额不变）

查询MySQL数据库中的数据。（已通过插入操作更改）

我不知道为什么MySQL数据库没有回滚？ DSS的分布式事务回滚需要什么条件

您似乎没有正确地将MySQL数据源配置为XA数据源。请在您的案例中使用“MySQL”数据源的此示例配置

你能在这里发布相关.dbs文件的内容吗？我已经添加了相关.dbs文件的内容。请确认。谢谢你的帮助，它很有效！我还有一个问题。控制台的向导似乎无法完成此配置。但只能通过直接编辑dbs文件的方式。如果开发人员不熟悉dbs文件，则无法完成此配置。如果您愿意将数据源添加为XA数据源，则必须通过提供必要的属性从向导中将其添加为外部数据源。请参阅中的“数据源提供程序”部分。感谢您的帮助。您知道如何配置Oracle和MongoDB的XA数据源吗？Oracle.jdbc.XA.client.oraclexadasource中的Oracle XA驱动程序类
