搭建SpringMVC+MyBatis开发框架一

大部分 Java 应用都是 Web 应用，展现层是 Web 应用不可忽略的重要环节。Spring 为展现层提供了一个优秀的 Web 框架—— Spring MVC。和众多其他 Web 框架一样，它基于 MVC 设计理念，此外，它采用了松散耦合可插拔组件结构，比其他 MVC 框架更具扩展性和灵活性。

SpringMVC + Mybatis 框架非常成熟，能够快速搭建项目。各大电商网站如京东、珍品网等都在使用这一框架组合。

本篇在前面“用Maven创建第一个项目”的代码基础上，将这个项目配置为支持SpringMVC框架。

将pom.xml的配置拷贝进去，更新maven引用包依赖：

注意：

1.从“<properties>”开始一直到结尾的都可以直接拷，原来顶部的的项目信息可以保留：

2.拷贝前可以到“http://mvnrepository.com”查询各个jar包的最新版本号：



3.保存pom.xml后，Eclipse会自动运行Building workspace从远程获取相应的jar包，耐心等待完成。

4.发现Markers下面提示了一个错误，可以用"Command + 1"进行修复：



5.现在多了很多jar包引用：
