SpringMVC项目结构

这里是项目搭建的大致目录结构

需要注意的是：×××Mapper.xml这个文件不能放在com.mvc.mapper这个包中，因为他不是java文件，所以不会一同编译，也就是说，生成的文件中并不包含这个,所以需要将这个×××Mapper.xml放在resources源文件里，但是又要求×××Mapper.xml所在的文件包名要和他所实现的mapper接口保持一致，所以可以在resources里直接新建一个和com.mvc.mapper一样的文件夹，然后放进去，记住，文件夹新建时需要注意的事项，正确的输入：com/mvc/mapper ,其他的也没有需要特别注意的地方，看着上面的目录结构建就可以了。

下面是pom.xml的依赖包和插件，写的有注释
