使用Spring MVC,配置DispatcherServlet是第一步。 DispatcherServlet是前置控制器,配置在web.xml文件中的。他用来拦截匹配的请求,Servlet拦截匹配规则要自已定义,把拦截下来的请求,依据某某规则分发到目标Controller(我们写的Action)来处理。   “某某规

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

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

[html] view plain copy print ?
  1. <beans xmlns="http://www.springframework.org/schema/beans" 
  2. xmlns:context="http://www.springframework.org/schema/context" 
  3. xmlns:p="http://www.springframework.org/schema/p" 
  4. xmlns:mvc="http://www.springframework.org/schema/mvc" 
  5. xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
  6. xsi:schemaLocation="http://www.springframework.org/schema/beans 
  7.       http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
  8.       http://www.springframework.org/schema/context 
  9.       http://www.springframework.org/schema/context/spring-context.xsd 
  10.       http://www.springframework.org/schema/mvc 
  11.       http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd"> 
  12.      <!-- 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--> 
  13.      <mvc:annotation-driven /> 
  14.      <!-- 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 --> 
  15.      <context:component-scan base-package="com.mvc.rest" /> 
  16.      <!-- 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 --> 
  17.      <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/view/" p:suffix=".jsp" /> 
  18. </beans> 
<beans xmlns="http://www.springframework.org/schema/beans"
 xmlns:context="http://www.springframework.org/schema/context"

     <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

[html] view plain copy print ?
  1. package com.mvc.rest; 
  2. import javax.servlet.http.HttpServletRequest; 
  3. import javax.servlet.http.HttpServletResponse; 
  4. import org.springframework.stereotype.Controller; 
  5. import org.springframework.ui.ModelMap; 
  6. import org.springframework.web.bind.annotation.PathVariable; 
  7. import org.springframework.web.bind.annotation.RequestMapping; 
  8. import org.springframework.web.bind.annotation.RequestMethod; 
  9. import org.springframework.web.servlet.ModelAndView; 
  10. @Controller 
  11. public class RestConstroller { 
  12.     public RestConstroller() {} 
  13.     @RequestMapping(value = "/login/{user}", method = RequestMethod.GET) 
  14.     public ModelAndView myMethod(HttpServletRequest request,HttpServletResponse response,  
  15.             @PathVariable("user") String user, ModelMap modelMap) throws Exception { 
  16.         modelMap.put("loginUser", user); 
  17.         return new ModelAndView("/login/hello", modelMap); 
  18.     } 
  19.     @RequestMapping(value = "/welcome", method = RequestMethod.GET) 
  20.     public String registPost() { 
  21.         return "/welcome"; 
  22.     } 
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:

[html] view plain copy print ?
  1. <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 
  2. <% 
  3. String path = request.getContextPath(); 
  4. String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; 
  5. %> 
  6. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> 
  7. <html> 
  8. <head> 
  9. <base href="<%=basePath%>"> 
  10. <title>My JSP 'hello.jsp' starting page</title> 
  11. <meta http-equiv="pragma" content="no-cache"> 
  12. <meta http-equiv="cache-control" content="no-cache"> 
  13. </head> 
  14. <body> 
  15.     你好:<%=request.getAttribute("loginUser") %>,现在时间是<%= new Date() %> 
  16. </body> 
  17. </html> 
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
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">
</head>
<body>
	你好:<%=request.getAttribute("loginUser") %>,现在时间是<%= new Date() %>
</body>
</html>


3、部署访问
http://localhost:8080/kdzj/welcome
