为了简单，将spring-framework中dist下的所有jar包拷贝到项目的WEB-INF/lib目录下
需要添加Apache commons logging日志，此处使用的是commons.logging
web.xml中添加如下配置：
<?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">
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<session-config>
<session-timeout>30</session-timeout>
</session-config>
<filter>
<filter-name>CharacterEncodingFilter</filter-name>
<filter-class>
org.springframework.web.filter.CharacterEncodingFilter
</filter-class>
<init-param>
<param-name>encoding</param-name>
<param-value>utf-8</param-value>
</init-param>
<init-param>
<param-name>forceEncoding</param-name>
<param-value>true</param-value>
</init-param>
</filter>
<filter-mapping>
<filter-name>CharacterEncodingFilter</filter-name>
<url-pattern>/*</url-pattern>
</filter-mapping>
<servlet>
<servlet-name>dispatcherServlet</servlet-name>
<servlet-class>
org.springframework.web.servlet.DispatcherServlet
</servlet-class>
<init-param>
<param-name>contextConfigLocation</param-name>
<param-value>/WEB-INF/spring/*.xml</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>dispatcherServlet</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
以上配置已经增加了由spring提供的编码过滤器来解决乱码问题
编写MVC控制配置文件mvc-config.xml，该文件在WEB-INF的spring文件下，而web.xml中已经配置加载该文件夹下的所有xml文件
<?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:p="http://www.springframework.org/schema/p"
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">
<!-- prefix和suffix：查找视图页面的前缀和后缀（前缀[逻辑视图名]后缀）
比如传进来的逻辑视图名为hello，则该该jsp视图页面应该存放在“WEB-INF/jsp/hello.jsp” -->
<bean
class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
<bean name="/hello.do" class="test.HelloWorldController" />
</beans>
编写控制的类，该类接受参数，设置该参数为视图数据
package test;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.Controller;
// http://localhost:8080/spring/hello.do?user=java
public class HelloWorldController implements Controller{
public ModelAndView handleRequest(HttpServletRequest request,
HttpServletResponse response) {
ModelAndView mv = new ModelAndView();
// 添加模型数据 可以是任意的POJO对象
mv.addObject("user", request.getParameter("user"));
// 设置逻辑视图名，视图解析器会根据该名字解析到具体的视图页面
mv.setViewName("hello");
return mv;
}
}
视图使用JSP，页面很简单。在WebRoot下新建文件夹jsp，新建jsp命名为hello.jsp。
<%@ page language="java" pageEncoding="UTF-8"%>
<html>
<head>
<title>SpringMVC</title>
</head>
<body>
您好，${user }!
</body>
</html>
访问路径http://localhost:8080/spring/hello.do?user=java 看效果。
