经过今天上午的学习发现spring上手开发一个"hello world"真的非常简单。
开发环境搭建：
1、去spring官网下载spring-framework-3.2.11.RELEASE-dist.zip 。这里带dist的是二进制的jar包，不带dist的是源代码
2、eclipse下新建一个java项目，把上面的包解压后的jar都引用到项目里去，还要再引入一个commons-logging.jar不然会报日志logging factory找不到的错误。
运行《spring in action 3rd Edition》chapter 2中的例子：
package com.springinaction.springidol; public interface Performer { void perform() throws PerformanceException; }
package com.springinaction.springidol; public class Juggler implements Performer{ private int bags = 3; public Juggler(){ } public Juggler(int bags){ this.bags = bags; } public void perform() throws PerformanceException{ System.out.println("Juggling "+ this.bags + " bags."); } }
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd"> <!-- Beans declararions go here --> <bean id="duke" class="com.springinaction.springidol.Juggler"></bean> </beans>
ApplicationContext ctx = new ClassPathXmlApplicationContext("com/springinaction/springidol/spring-idol.xml");
Performer performer = (Performer)ctx.getBean("duke");
performer.perform();
运行结果：Juggling 3 bags.
