HTTP状态500 – servlet appServlet的Servlet.init（）引发exception
我想尝试一个简单的程序，但得到以下错误。 我正在使用Eclipse Kelper和Tomcat 7.0。 尝试过很多东西，但没有什么对我有用。

servlet的context.xml中：

有人可以解释一下是什么问题吗？
尝试此配置或相应地重命名您的配置：我更喜欢将servlet命名为“dispatcher”，将其上下文文件命名为dispatcher-servlet.xml。 它对我来说很好。
dispatcher org.springframework.web.servlet.DispatcherServlet contextConfigLocation /WEB-INF/spring/appServlet/dispatcher-servlet.xml 1 dispatcher /
Servlet.init（）错误主要是由于您的spring MVC的Jar文件版本不匹配而导致的，通过右键单击项目> properties> build path检查所有库，并删除任何不匹配的jar版本。
还要从lib文件夹中删除jar库。 再次构建项目并运行它。
试试这个：servlet-context.xml：
