1.新建工程，把spring所需的包copy到工程里
2.配置前端控制器Dispatcher
web.xml
<?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">
<display-name></display-name>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
<servlet>
<servlet-name>springmvc</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>springmvc</servlet-name>
<url-pattern>*.do</url-pattern>
</servlet-mapping>
</web-app>
3.在WEB-INF下创建一个spring mvc的xml配置文件，servletname（springmvc）-servlet.xml(命名规则)
配置handlermapping（可以省略此步）
springmvc-servlet.xml
<?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"
xsi:schemaLocation="
http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean class="org.springframework.web.servlet.mvc.support.ControllerBeanNameHandlerMapping" />
<bean name="hello.do" class="zou.huiying.HelloController"></bean>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/view/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
4.创建jsp页面
hello.jsp
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8" %>
<html>
<head>
<title>this is helloworld</title>
</head>
<body>
<form action="hello.do" method="post">
hello:<input type="text" name="hello" />
<input type="submit" value="tijiao" />
</form>
</body>
</html>
5,创建controller
HelloController.java
package zou.huiying;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;
public class HelloController extends AbstractController {
@Override
protected ModelAndView handleRequestInternal(HttpServletRequest request,
HttpServletResponse response) throws Exception {
// TODO Auto-generated method stub
String hello=request.getParameter("hello");
System.out.println("---------"+hello);
ModelAndView mav= new ModelAndView("aa");
mav.addObject("helloworld", "nihao"+hello);
System.out.println("---------");
return mav;
// return new ModelAndView(new RedirectView(this.getViewPage()));
}
}
6.指定返回页面
aa.jsp
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">
<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">
<meta http-equiv="expires" content="0">
<meta http-equiv="keywords" content="keyword1,keyword2,keyword3">
<meta http-equiv="description" content="This is my page">
<!--
<link rel="stylesheet" type="text/css" href="styles.css">
-->
</head>
<body>
This is my JSP page. <br>
<h1>${helloword}</h1>
</body>
</html>
7.配置视图解析器
8.配置controller
上面已经配置好
