Spring MVC 案例一：环境配置

Spring MVC 案例一：环境配置

1. maven导入jar包

<dependency>
    <groupId>org.springframeworkgroupId>
    <artifactId>spring-webmvcartifactId>
    <version>4.3.8.RELEASEversion>
dependency>

2. web.xml中配置DispatcherServlet（前端控制器）
   前端控制器收到请求后自己不进行处理，而是委托给其他的解析器进行处理，作为统一访问点，进行全局的流程控制；

<servlet>
	<servlet-name>DispatcherServletservlet-name>
	<servlet-class>org.springframework.web.servlet.DispatcherServletservlet-class>
	<init-param>
		<param-name>contextConfigLocationparam-name>
		<param-value>classpath:springmvc.xmlparam-value>
	init-param>
servlet>
<servlet-mapping>
	<servlet-name>DispatcherServletservlet-name>
	<url-pattern>*.actionurl-pattern>
servlet-mapping>

3.在classpath下创建配置文件springmvc.xml(使用插件向导)

<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

beans>
