在寫springMVC時，導入所有需要的包后，運行程序，控制台報以下錯誤：

嚴重: Servlet [springDispatcherServlet] in web application [/SpringMVC-1] threw load() exception

隨便在一個java文件中都無法import org.springframework.web.servlet.DispatcherServlet，這個類主要是在spring-webmvc jar包下，所有導入的jar包如下：

都已經導入，沒有問題。但是實際上還要把依賴都加進classpath下。步驟：

項目右擊-->properties-->Deployment Assembly-->add-->Java Build Path Entries-->導入所有依賴的Jar包，重新start tomcat即可。
