搭建springmvc

1,下载jar包,我下的是:
spring-framework-3.1.0.RELEASE-with-docs.zip
spring-framework-3.0.5.RELEASE-dependencies.zip
引入dist目录下除了下面三个其余所有包:
org.springframework.web.struts-3.1.0.RELEASE.jar
org.springframework.spring-library-3.1.0.RELEASE.libd
org.springframework.web.portlet-3.1.0.RELEASE.jar
引入依赖包下:
com.springsource.org.apache.commons.logging-1.1.1.jar,
com.springsource.org.aopalliance-1.0.0.jar


spring框架配置:
1,web.xml配置:

<?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_3_0.xsd"  
    id="WebApp_ID"   
    version="3.0">  
    <context-param>  
        <param-name>contextConfigLocation</param-name>  
        <!-- 应用上下文配置文件 -->  
        <param-value>/WEB-INF/spring-servlet.xml</param-value>  
    </context-param>
    <listener>  
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>  
    </listener>  
    <!-- 配置spring核心servlet -->  
    <servlet>  
        <servlet-name>spring</servlet-name>  
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>  
        <load-on-startup>1</load-on-startup>  
    </servlet>  
    <!-- url-pattern配置为/,不带文件后缀,会造成其它静态文件(js,css等)不能访问。如配为*.do,则不影响静态文件的访问 -->  
    <servlet-mapping>  
        <servlet-name>spring</servlet-name>  
        <url-pattern>/</url-pattern>  
    </servlet-mapping>  
</web-app>

  

2,应用上下文配置:
spring-servlet.xml即配置用于开启基于注解的springMVC功能,照web.xml中设定,路径为WEB-INF下

<beans xmlns="http://www.springframework.org/schema/beans"  
 xmlns:context="http://www.springframework.org/schema/context"  
 xmlns:p="http://www.springframework.org/schema/p"  
 xmlns:mvc="http://www.springframework.org/schema/mvc"  
 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-3.0.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-3.0.xsd">  
     <!-- 启动注解驱动的Spring MVC功能,注册请求url和注解POJO类方法的映射-->  
     <mvc:annotation-driven />  
     <!-- 启动包扫描功能,以便注册带有@Controller、@Service、@repository、@Component等注解的类成为spring的bean -->  
     <context:component-scan base-package="com.mvc.rest" />  
     <!-- 对模型视图名称的解析,在请求时模型视图名称添加前后缀 -->  
     <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/view/" p:suffix=".jsp" />  
</beans>

  

Demo例子:
1、根据spring-servlet.xml配置的包路径(com.mvc.rest)新建Constroller

package com.mvc.rest;  
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
@Controller  
public class RestConstroller {   
    @RequestMapping(value = "/hello.act", method = RequestMethod.GET)  
    public String registPost() {  
        return "/hello";  
    }  
}

  

2、建jsp视图
视图路径在spring-servlet.xml配置(/WEB-INF/view/),据上述RestConstroller 类,我们在WEB-INF下建立view目录,在view下建立welcome.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 'hello.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. hello<br>
  </body>
</html>
