今天初步学习了下spring框架，现在把学习过程总结一下。

一、创建项目

1、项目结构图

2、工程配置文件web.xml

<context-param><param-name>contextConfigLocation</param-name><param-value>/WEB-INF/applicationContext.xml,/WEB-INF/aspect-spring.xml</param-value></context-param><listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener>

3、创建业务逻辑接口

package com.intf;import com.bean.Student;public interface IGame {String play(Student stu);}

4、创建两个接口实现类

[1]

package com.bean;import com.intf.IGame;public class LianLianKanGame implements IGame{public String play(Student stu){return stu.getName()+" is doing LianLianKanGame now!";}}

[2]

package com.bean;import com.intf.*;public class PingTuGame implements IGame{public String play(Student stu){return stu.getName()+" is doing PingTuGame now!";}}

5、创建一个实体类

package com.bean;public class Student {private String id;private String name;public Student(String id){this.id = id;}public String getId() {return id;}public void setId(String id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}

6、创建applicationContext.xml

        <bean id="IGameImpl" class="com.bean.PingTuGame" /><bean id="stu_default" class="com.bean.Student" >     <!--构造器注入--> <constructor-arg><value>110</value></constructor-arg><!-- Setter注入--><property name="name">    <value>zhaozp</value></property></bean>

7、创建主测试页面

<%@page import="org.springframework.web.context.support.WebApplicationContextUtils"%><%@page import="org.springframework.web.context.WebApplicationContext"%><%@page import="com.intf.*"%><%@page import="com.bean.*"%><html><head><meta http-equiv="Content-Type" content="text/html charset=utf-8"><title>Game Start!</title></head><body><%WebApplicationContext iocBeanFactory =WebApplicationContextUtils.getWebApplicationContext(application);Student stu_default = (Student)iocBeanFactory.getBean("stu_default");IGame game = (IGame)iocBeanFactory.getBean("IGameImpl");out.println(game.play(stu_default));%></body></html>

运行结果：

zhaozp is doing PingTuGame now!
