最后的报错关键报错:Servlet mapping specifies an unknown servlet name springMVC
解决办法:找到项目的web.xml中配置的文件

    
        spring
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:/spring/springmvc.xml
        
        1
    
    
        spring
        *.do
    
    
        springMVC
        /
    

一个最明显的错误:其中...spring...与springMVC的servlet-name不相同.
修改后可以正常运行
