配置springMVC

1、web.xml 前端控制器

配置规则：
*.do: 拦截请求路径所有的后缀为.do;
/* : 拦截所有, .jsp页面也会拦截; 不会使用此配置, 因为视图会无法跳转;
/ : 拦截所有, .jsp页面不会被拦截; 会拦截.js .css .png; (需要配置对静态资源放行)

注意: 本项目中: 后台使用*.do; 前台使用/; 单点登录使用*.aspx;

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee"  
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
    http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">

     <!-- Springmvc -->
    <servlet>
        <servlet-name>console</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <!-- 默认: WEB-INF/[servlet-name]-servlet.xml -->
        <init-param>
            <param-name>contextConfigLocation</param-name>
            <param-value>classpath:springmvc-console.xml</param-value>
        </init-param>
    </servlet>

    <!-- 配置规则-->
    <servlet-mapping>
        <servlet-name>console</servlet-name>
        <url-pattern>*.do</url-pattern>
    </servlet-mapping>

</web-app>

2、 springmvc-console.xml文件中配置：扫描、处理器映射器、适配器、视图解释器
