基于配置的Spring MVC3

网上查找的spring mvc3大部分都是基于注射的方式，总感觉注射有点怪怪。不利于后期扩展和项目管理，于是特意写下这篇基于xml配置的Spring MVC3。以供大家參考。

怎么建立web项目和下载相关jar这里就不说了，直接写下关键内容。

1. 所需jar

aopalliance-1.0.0.jar

commons-logging.jar

jsp-api.jar

jstl-1.2.jar

servlet-api.jar

spring-aop-3.2.9.RELEASE.jar

spring-beans-3.2.9.RELEASE.jar

spring-context-3.2.9.RELEASE.jar

spring-context-support-3.2.9.RELEASE.jar

spring-core-3.2.9.RELEASE.jar

spring-expression-3.2.9.RELEASE.jar

spring-web-3.2.9.RELEASE.jar

spring-webmvc-3.2.9.RELEASE.jar

standard-1.1.2.jar

<span style="font-family: Arial, Helvetica, sans-serif; background-color: rgb(255, 255, 255);">2. web.xml配置</span>

<?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" 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">

  <display-name>baseweb</display-name>
  <context-param>
     <param-name>webAppRootKey</param-name>
     <param-value>web.base</param-value>
  </context-param>

  <!-- Spring配置 -->
  <!-- ====================================== -->
  <listener>
	   <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
  </listener> 

  <!-- 指定Spring Bean的配置文件所在文件夹。默认配置在WEB-INF文件夹下 -->
  <context-param>
	   <param-name>contextConfigLocation</param-name>
	   <param-value>/WEB-INF/webxml/applicationContext.xml</param-value>
  </context-param>

  <servlet>
    <servlet-name>dispatcher</servlet-name>
    <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
      <init-param>
        <param-name>contextConfigLocation</param-name>
	    <param-value>/WEB-INF/webxml/dispatcher-servlet.xml</param-value>
      </init-param>
    <load-on-startup>1</load-on-startup>
  </servlet>

  <servlet-mapping>
    <servlet-name>dispatcher</servlet-name>
    <url-pattern>*.do</url-pattern>
  </servlet-mapping>

  <welcome-file-list>
    <welcome-file>index.html</welcome-file>
    <welcome-file>index.htm</welcome-file>
    <welcome-file>index.jsp</welcome-file>
    <welcome-file>default.html</welcome-file>
    <welcome-file>default.htm</welcome-file>
    <welcome-file>default.jsp</welcome-file>
  </welcome-file-list>
</web-app>

3. 在WEB-INF下新建webxml文件夹，以下新建<span style="font-family: Arial, Helvetica, sans-serif;">dispatcher-servlet.xml和</span><span style="font-family: Arial, Helvetica, sans-serif;">applicationContext.xml</span>文件。

  <pre name="code" class="html"><span style="font-family: Arial, Helvetica, sans-serif;">dispatcher-servlet.xml</span>

<span style="font-family: Arial, Helvetica, sans-serif;">
</span>

<span style="font-family: Arial, Helvetica, sans-serif;"></span><pre name="code" class="html"><?xml version="1.0" encoding="UTF-8"?

34 新建IndexController.java

package com.liuxm.base.web;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.mvc.AbstractController;

public class IndexController extends AbstractController{

	private String success;

	@Override
	protected ModelAndView handleRequestInternal(HttpServletRequest request,
			HttpServletResponse response) throws Exception {
		return new ModelAndView(getSuccess());
	}

	public String getSuccess() {
		return success;
	}

	public void setSuccess(String success) {
		this.success = success;
	}

}

5. 在WEF-INF下新建jsp目录，在jsp新建index.jsp

<%@ page language="java" contentType="text/html; charset=UTF-8"
    pageEncoding="UTF-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>Insert title here</title>
</head>
<body>
This is index page .......
</body>
</html>

6. 在tomcat中执行web，输入http://xxxxxxx/xx/index.do
