web框架之Spring-MVC环境搭建

spring框架jar包

1、下载spring源包
spring地址：http://www.springsource.org/download
我下的是spring-framework-3.1.0.RELEASE-with-docs.zip
下载依赖包：spring-framework-3.0.5.RELEASE-dependencies.zip
注意官网上3.0.3版本以后同版本依赖包不提供下载

2、导入所需jar包
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及com.springsource.org.aopalliance-1.0.0.jar

spring框架配置

1、web.xml配置

	
        contextConfigLocation
        
        /WEB-INF/spring-servlet.xml
  	
	
        org.springframework.web.context.ContextLoaderListener
 	
 	
	
		spring
		org.springframework.web.servlet.DispatcherServlet
		1
	
	
	
		spring
		/
	

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

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 javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.stereotype.Controller;
import org.springframework.ui.ModelMap;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class RestConstroller {
	public RestConstroller() {}
	@RequestMapping(value = "/login/{user}", method = RequestMethod.GET)
	public ModelAndView myMethod(HttpServletRequest request,HttpServletResponse response, 
			@PathVariable("user") String user, ModelMap modelMap) throws Exception {
		modelMap.put("loginUser", user);
		return new ModelAndView("/login/hello", modelMap);
	}
	@RequestMapping(value = "/welcome", method = RequestMethod.GET)
	public String registPost() {
		return "/welcome";
	}
}

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及login/hello.jsp
welcome.jsp随意，hello.jsp代码如下：

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>









	你好:<%=request.getAttribute("loginUser") %>，现在时间是<%= new Date() %>
