spring mvc + ibatis + Oracle + ajax 轻量级架构搭建及详解

feinifi 2014-10-29

       现在主流的Web MVC框架除了Struts这个主力 外,其次就是Spring MVC了,因此这也是作为一名程序员需要掌握的主流框架,框架选择多了,应对多变的需求和业务时,可实行的方案自然就多了。不过要想灵活运用Spring MVC来应对大多数的Web开发,就必须要掌握它的配置及原理。

一、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

二、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

三、spring框架配置

1、web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 
	xmlns="http://java.sun.com/xml/ns/javaee" 
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
	xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
	http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
	<!--配置Sring MVC的核心控制器DispatcherServlet -->
    <servlet>
        <servlet-name>dispatcherServlet</servlet-name>
        <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
        <init-param>  
	        <param-name>contextConfigLocation</param-name>  
	        <param-value>classpath*:/spring-*.xml</param-value>  
    	</init-param>  
    	<load-on-startup>1</load-on-startup>
    </servlet>
    <!-- 为DispatcherServlet建立映射 -->
    <servlet-mapping>
         <servlet-name>dispatcherServlet</servlet-name>
         <url-pattern>*.html</url-pattern>
    </servlet-mapping>
    
	<context-param> 
	  <param-name>log4jConfigLocation</param-name> 
	  <param-value>classpath:/log4j.properties</param-value> 
	</context-param> 

	<!-- 配置log4j.xml监听器 --> 
	<listener> 
	<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class> 
	</listener> 

	<!-- 解决工程编码过滤器 -->  
	<filter>  
        <filter-name>encodingFilter</filter-name>  
        <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class>  
        <init-param>  
            <param-name>encoding</param-name>  
            <param-value>UTF-8</param-value>  
        </init-param>  
    </filter>  
    <filter-mapping>  
        <filter-name>encodingFilter</filter-name>  
        <url-pattern>/*</url-pattern>  
    </filter-mapping>
    
  <display-name></display-name>	
  <welcome-file-list>
    <welcome-file>index.jsp</welcome-file>
  </welcome-file-list>
</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
