搭建spring MVC项目

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：
