Question

我正在开发一个Spring Roo网络应用程序，并且需要使用每隔一段时间在后台运行的Scheduled方法，然后我添加了一些到我的applicationContext.xml的行，该方法运行正常，但随后发现应用程序无法设置/读取事务管理器，控制台说The matching wildcard is strict, but no declaration can be found for element 'tx:annotation-driven'.

我已经搜索过了，并在本网站上找到了这个错误消息的2或3个答案，例如：

将xmlns:tx="http://www.springframework.org/schema/tx添加到标题[已完成]
在component:scan [已完成]之前添加tx:annotation但是当我尝试在服务器上运行我的应用时，它会抛出一个HTTP Status 404 The Requested Resource is not available，你能吗？帮我修复xml文件？

这是我的applicationContext.xml文件：

您通过执行

声明了tx命名空间的用法

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

但您忘记在xsi:schemaLocation属性中声明此命名空间的xsd位置：

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