Spring学习-helloworld使用xml配置

Spring3对Java JDK版本的最低要求是1.5

1、新建Java project，在build path中加入org.springframework.core-3.0.3.RELEASE.jar，org.springframework.beans-3.0.3.RELEASE.jar两个jar包

2、新建spring3包，新建Spring3HelloWorld类，代码如下：

package spring3;
public class Spring3HelloWorld {
 public void sayHello(){
       System.out.println("Hello world~!!");
}
}

 3、新建Spring3HelloWorld.xml文件，代码如下：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:aop="http://www.springframework.org/schema/aop"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">
<bean id="Spring3HelloWorldBean" class="spring3.Spring3HelloWorld" />
</beans>

 4、新建Spring3HelloWorldTest类，代码如下：

package spring3;

import org.springframework.beans.factory.xml.XmlBeanFactory;
import org.springframework.core.io.ClassPathResource;

public class Spring3HelloWorldTest {
/**
* @param args
*/
public static void main(String[] args) {
XmlBeanFactory beanFactory = new XmlBeanFactory(new ClassPathResource(
"spring3/Spring3HelloWorld.xml"));
Spring3HelloWorld myBean = (Spring3HelloWorld) beanFactory
.getBean("Spring3HelloWorldBean");
myBean.sayHello();
}
}

 5、运行程序需要commons-logging-1.1.jar，到http://commons.apache.org/logging/下载
