[Spring in Action] 2. Hello Spring

    这一篇就亲自实践一个简单的Spring应用。依旧类似人见人爱的“Hello World”, 不过稍微有些改动，是“Hello Spring”.

    HelloWorld.java

package hello.spring;

public class HelloWorld {
	private String words;

	public String getHello() {
		return words;
	}

	public void setHello(String words) {
		this.words = words;
	}
	
	public void show(){
		System.out.println("Message: "+this.words);
	}
}

    Spring bean配置文件：myspring.xml

<?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-2.5.xsd"
	<bean id="myBean" class="hello.spring.HelloWorld">
		<property name="hello">
			<value>Hello Spring!</value>
		</property>
	</bean>
</beans>

    HelloSpring.java

package hello.spring;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

public class HelloSpring {
	public static void main(String[] args){
		ApplicationContext ctx = new FileSystemXmlApplicationContext("src/myspring.xml");
		HelloWorld hw = (HelloWorld)ctx.getBean("myBean");
		hw.show();
	}
}

    需要的文件已经全部编写完成，赶快运行看看，”Hello Spring!"
