新手一枚，希望有错误的地方多多指教。
工程所用到网址——Maven Repository、MyBatis Genetator、Bootstrap
配置文件
pop.xml——导入所要的jar包（Spring、SpringMVC、MyBatis.....)
——Spring MVC:spring webmvc、spring jdbc、spring aspect、
——MyBatis:mybatis、mybatis spring、c3p0、mysql、
——其他:jstl、servlet-api、junit、Mybatis Generator Core
dispatcherServlet-servlet.xml对应SprinfMVC配置文件
applicationContext.xml对应Spring配置文件
mybatis-config.xml
web.xml
mbg.xml逆向工程生成文件
dbconfig.properties文件封装连接数据库的文件
