Mule Studio如何創建全局變量

Question

click hear to see my flow Image

我的測試騾應用程序。 我用捲曲的JSON數據發佈到HTTP的終點和tranforms JSON反對，並與域名（＃[message.payload.name]）

在我的數據庫中插入我使用追趕異常策略保持錯誤日誌（情況下的唯一名稱）

我想更新我的狀態表中字段＃[message.payload.name] - 意味着更新mytable的設置姓=＃[message.payload.name]

但在catch-exception-strategy無法訪問＃[message.payload.name]

我的配置

根據你想有一個某種全局變量的標題，一個辦法是，你可以嘗試使用flowVars作爲速戰速決。使用Mule Studio它與變量（在變形金剛下）相同。

您在catch catch例外策略中得到的消息是例外。
