1.創建web項目
2.引入類庫
com.springsource.javax.servlet.jsp.jstl-1.1.2.jar
com.springsource.org.aopalliance-1.0.0.jar
com.springsource.org.apache.commons.logging-1.1.1.jar
com.springsource.org.apache.taglibs.standard-1.1.2.jar
org.springframework.aop-3.0.0.RELEASE.jar
org.springframework.asm-3.0.0.RELEASE.jar
org.springframework.beans-3.0.0.RELEASE.jar
org.springframework.context.support-3.0.0.RELEASE.jar
org.springframework.context-3.0.0.RELEASE.jar
org.springframework.core-3.0.0.RELEASE.jar
org.springframework.expression-3.0.0.RELEASE.jar
org.springframework.web.servlet-3.0.0.RELEASE.jar
org.springframework.web-3.0.0.RELEASE.jar
3在web.xml文件中配置DispatcherServlet
<?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/web-app_2_5.xsd"
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">
<display-name>lsn_springmvcold414</display-name>
<!-- 配製spring分發器servlet -->
<servlet>
<servlet-name>action</servlet-name>
<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
</servlet>
<servlet-mapping>
<servlet-name>action</servlet-name>
<url-pattern>*.action</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>index.html</welcome-file>
</welcome-file-list>
</web-app>
4.創建控制器HomeController
public class HomeController extends AbstractController {
@Override
protected ModelAndView handleRequestInternal(HttpServletRequest req,
HttpServletResponse resp) throws Exception {
System.out.println("HomeController-------" + req.getParameter("name"));
//req.setAttribute("msg", "hello " + req.getParameter("name"));
return new ModelAndView("home","msg","hello " + req.getParameter("name"));//home爲邏輯名
}
}
5創建spring配置文件/WEB-INF/action-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"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.0.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.0.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.0.xsd ">
<!-- 控制器 -->
<bean name="/home.action" class="cn.itcast.springmvc.controller.HomeController">
</bean>
<!-- 內部資源視圖解析器 -->
<bean id="internalResourceViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- 前綴 -->
<property name="prefix" value="/WEB-INF/jsps/" />
<!-- 後綴 -->
<property name="suffix" value=".jsp" />
</bean>
</beans>
6.創建jsp./WEB-INF/jsps/index.jsp
<%@ page language="java" contentType="text/html; charset=utf-8"%>
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<title>index.jsp</title>
</head>
<body>
hello world
</body>
</html>
幾種HandlerMapping介紹
* BeanNameUrlHandlerMapping （默認）
* SimpleUrlHandlerMapping
* ControllerClassNameHandlerMapping
<!-- bean名url處理器映射 -->
<bean id="beanNameUrlHandlerMapping" class="org.springframework.web.servlet.handler.BeanNameUrlHandlerMapping">
<property name="order" value="1" />
</bean>
<!-- 簡單url處理器映射 -->
<bean id="simpleUrlHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
<property name="mappings">
<props>
<prop key="/bbb.action">helloController</prop>
</props>
</property>
<property name="order" value="2" />
</bean>
<!-- 控制器類名處理器映射 -->
<bean id="controllerClassNameHandlerMapping" class="org.springframework.web.servlet.mvc.support.ControllerClassNameHandlerMapping">
<property name="order" value="3" />
</bean>
以上HandleMapping建議使用默認的
