爲計劃方法

Question

我工作的一個Spring Roo的Web應用程序，並需要使用，在後臺運行，每隔一定時間排定方法Spring的ApplicationContext的配置，然後我添加了一些 行我applicationContext.xml中，並且該方法跑了好了，但隨後發生 該應用程序無法設置/讀取 transactionManager的，控制檯說：The matching wildcard is strict, but no declaration can be found for element 'tx:annotation-driven'.

我已經搜查，並在此網站上發現，2個或3回答此錯誤消息，這樣的aS：

1. add xmlns:tx="http://www.springframework.org/schema/tx to th Ë 頭[已經完成]
2. tx:annotation前加component:scan [已經完成]但是當我嘗試在服務器上運行我的應用程序，它拋出一個 HTTP Status 404 The Requested Resource is not available，你能 幫我解決xml文件？

這是我的applicationContext.xml文件：

你做

xmlns:tx="http://www.springframework.org/schema/tx" 

宣佈tx命名空間的使用，但你忘了申報XSD的位置，此命名空間中xsi:schemaLocation屬性：

http://www.springframework.org/schema/tx 
http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
