I know this is a duplicate and you people are gonna chide me for it, but I didn't get a proper solution after reading all the posts.
I am trying to build a Spring Template application in Spring Source Tool Suite. I am getting the following error.

我知道这是重复的，你们会因此而责备我，但在阅读所有帖子后我没有得到正确的解决方案。
我正在尝试在 Spring Source Tool Suite 中构建一个 Spring 模板应用程序。我收到以下错误。

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException: Line 16 in XML document from ServletContext resource [/WEB-INF/spring/appServlet/servlet-context.xml] is invalid; nested exception is org.xml.sax.SAXParseException: cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'resources'.

org.springframework.beans.factory.xml.XmlBeanDefinitionStoreException：来自 ServletContext 资源 [/WEB-INF/spring/appServlet/servlet-context.xml] 的 XML 文档中的第 16 行无效；嵌套异常是 org.xml.sax.SAXParseException：cvc-complex-type.2.4.c：匹配的通配符是严格的，但找不到元素“资源”的声明。

Please let me know if there is a jar file missing in my application.
These are the only jar files I have in my application:

如果我的应用程序中缺少 jar 文件，请告诉我。
这些是我的应用程序中仅有的 jar 文件：

Your XML is fine, but according to this comment on a SpringSource blog post about Spring MVC 3

您的 XML 很好，但根据有关 Spring MVC 3 的 SpringSource 博客文章的评论

The <mvc:resources/>tag is a new feature coming in Spring Framework 3.0.4

该<mvc:resources/>标签是Spring框架未来的一个新功能3.0.4

Your application uses Spring 3.0.3, so you need to upgrade to 3.0.4 or later to be able to use the resources tag.

您的应用程序使用 Spring 3.0.3，因此您需要升级到 3.0.4 或更高版本才能使用资源标签。
