浅谈springmvc的DispatcherServlet分析
本文介绍了springmvc的DispatcherServlet，分享给大家，具体如下：
一、程序
（一）web.xml文件中的内容
（二）src/main/resource/springmvc/spring-mvc.xml中的内容
p:prefix="/WEB-INF/view/" p:suffix=".jsp"/> （三）src/main/java/com/z/controller/IndexController.java中的内容 package com.z.controller; import javax.servlet.http.HttpServletRequest; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.servlet.ModelAndView; @Controller public class IndexController { @RequestMapping("/index.html") public ModelAndView getIndex(HttpServletRequest request) throws Exception { ModelAndView mav = new ModelAndView("index"); return mav; } } （四）src/main/webapp/WEB-INF/view/index.jsp <%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%> <% String path = request.getContextPath(); String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/"; %>
<html>
p:prefix="/WEB-INF/view/" p:suffix=".jsp"/>
（三）src/main/java/com/z/controller/IndexController.java中的内容
package com.z.controller;
import javax.servlet.http.HttpServletRequest;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.servlet.ModelAndView;
@Controller
public class IndexController {
@RequestMapping("/index.html")
public ModelAndView getIndex(HttpServletRequest request) throws Exception {
ModelAndView mav = new ModelAndView("index");
return mav;
}
}
（四）src/main/webapp/WEB-INF/view/index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>
<html>
This is my JSP page.
