今天跟着教学视频一同搭建SSM框架，配置文件写完后跑了个测试

在此同时，存放mybatis配置文件的文件夹也大意拼错了，修正了之后

重新自信的重新跑一次。。。。结果又报错

看了下第一行，DispatcherServlet应该是springWebMVC下的类，难道是jar包出现了问题？还是pom文件配置错了？
我的spring版本为4.1.3，结果重新导入jar包也没有见效，最后想了一下，在web.xml中配置前端控制器的代码，按住ctrl左键果然没有跳过去，因为我的eclipse装有springIDE插件（强烈推荐使用，可以加强代码提示，再也不用一下一下的写出spring容器和前端控制器的复杂代码了），然后删除了源码，使用springIDE代码提示的DispatcherServlet，ctrl左键有了链接提示，重新跑了下。。。成功了。。。欣慰
