首先，是要放入spring mvc所需要的包：
如果不用json功能就不需要json和gson包,还有数据库驱动包，我这里是用的postgresql数据库，其他数据库需替换掉这个包
然后就是配置文件：
先是web.xml中需要加入以下内容：
<servlet>
<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>
classpath:applicationContext.xml
</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>Spring MVC Dispatcher Servlet</servlet-name>
<url-pattern>/</url-pattern>
</servlet-mapping>
然后是spring的配置文件applicationContext.xml：
<?xml version="1.0" encoding="UTF-8"?>

这样配置就差不多了，然后就可以写业务逻辑代码，和显示界面了。
未完待续。
