web框架之Spring-MVC环境搭建

1、新建web项目，并在web.xml加入spring mvc的servlet

<!-- spring mvc容器和servlet的定义 -->
  <servlet>
    <servlet-name>springMVC</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
    <!-- 这里的参数如果不配置，则默认查找web-inf下的{servlet-name}-servlet.xml文件 -->
    <init-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>/WEB-INF/springMVC.xml</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>
  <servlet-mapping>
    <servlet-name>springMVC</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>

 2、加入spring mvc的依赖jar包

备注:我这里除了spring的jar包外还添加了一些其他的功能（quartz、JSR303的hibernate实现、c3p0连接池、DB2驱动、spring json的支持(jackson)），这里并未完全加入spring的包，可根据项目的需要增减jar.

3、配置spring mvc的配置文件。

  1 <?xml version="1.0" encoding="UTF-8"?>
  2 <beans xmlns="http://www.springframework.org/schema/beans"
  3     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
