如何在 mule 3 中链接肥皂请求和响应答案

【问题标题】：How to link a soap request and response in mule 3如何在 mule 3 中链接肥皂请求和响应
【发布时间】：2012-01-15 20:29:15
【问题描述】：

我需要将文件发送到外部 Web 服务。当响应为1时，删除文件，否则保留文件。

我使用文件连接器发送文件，并在 Oracle 中插入一条记录。文件发送出去的时候，key就是文件connect的message id。我想保留消息 ID，以便在响应返回时使用此 ID 更新记录。

我尝试使用 MessagePropertiesTransformer 添加自定义属性，但响应没有保留它。有什么办法可以保留消息ID？

我的配置：

当我一个一个复制文件的时候是可以的，但是当我复制超过五个文件到目录时，有些记录无法更新。

 Executing SQL statement: 0 row(s) updated

【问题讨论】：

您是否尝试过在 message-properties-transformer 中使用“会话”范围而不是“出站”，然后使用 #[header:SESSION:test] 稍后检索它？

【解决方案1】：

将您的 JDBC 出站端点设置为请求-响应，以确保流程将在单个线程中执行。使用您当前的配置，2 个单独的 JDBC 请求将从流中“分离”并并行执行。
