starting microservice to obtain the Seata XID and then pass it to the ending microser‐ vice through RPC, and call io.seata.core.context.RootContext.bind(rpcXid) in the business function of the endpoint then generates the Statement corresponding to each grammar, which is processed by the appropriate Handler. 9.2.

JDBC 的场景下，跨多个微服务的事务场景需要考虑在起点微服务的上下 文使用 io.seata.core.context.RootContext.getXID() 获取 Seata XID 后通过 RPC 传递 给终点微服务，并在终点微服务的业务函数中调用 io.seata.core.context.RootContext. bind(rpcXid)。 2. 在使用 ShardingSphere 原理介绍 与标准 SQL 一样，DistSQL 由 ShardingSphere 的解析引擎进行识别，将输入语句转换为抽象语法树，进 而生成各个语法对应的 Statement，最后由合适的 Handler 进行业务处理。整体流程如下图所示： 9.2.
