1.拷贝jar文件

2.填充Web.xml

在/WEB-INF/web.xml中写入如下内容：

<?xml version="1.0" encoding="UTF-8"?>

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

<context-param>

<param-name>contextConfigLocation</param-name>

<param-value></param-value>

</context-param>

<listener>

<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>

</listener>

<servlet>

<servlet-name>x</servlet-name>

<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>

<init-param>

<param-name>contextConfigLocation</param-name>

<param-value>classpath*:x-servlet.xml</param-value>

</init-param>

</servlet>

<servlet-mapping>

<servlet-name>x</servlet-name>

<url-pattern>/</url-pattern>

</servlet-mapping>

</web-app>

?

context-param:指定applicationContext（bean定义）的位置；

servlet指定了ServletDispatcher以及servlet配置文件路径，如果是WEB-INF下面，"contextConfigLocation"节点的value采用"/WEB-INF/XX-servlet.xml"形式进行定义；如果是其他文件夹，则采用classpath形式进行指定；前者意味着servlet配置文件路径在WEB-INF下；后者意味着到编译后的文件夹中找配置文件；

?

3.填充x-servlet

在resources文件夹或者/WEB-INF/目录下创建x-servlet.xml，并填充如下内容：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

????xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:mvc="http://www.springframework.org/schema/mvc"

????xmlns:context="http://www.springframework.org/schema/context"

????xsi:schemaLocation="

????????http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd

http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd">

????<mvc:annotation-driven />

????<context:component-scan base-package="neusoft.monitor.controller" />

????<!-- jsp视图 -->

????<bean id="jspViewResolver"

????????class="org.springframework.web.servlet.view.InternalResourceViewResolver">

????????<property name="prefix" value="/WEB-INF/pages/" />

????????<property name="suffix" value=".jsp" />

????</bean>

</beans>

mvc:annotation-driven，代表通过注解进行设置controller；

context:component-scan，代表要进行扫描注解的包；

<bean id="jspViewResolver">定义了如何找到jsp页面；

4. 编写controller

@Controller

public class HomeController {

????@RequestMapping(value = "/home")

????public String showHomePage() {

????????return "home";

????}

}

编写home.jsp页面

随便写点什么；

5. 尝试访问

敲入网址localhost:8080/myspringmvc/home即可看到home.jsp内容。（myspringmvc是eclipse中工程的名称）
