HelloSpring經典入門

首先新建一個web工程，並通過MyEclipse加入Spring jar包

 

編寫Hello接口

package com.bean;

public interface Hello {

	public void hello();
}

 

編寫Hello接口實現類

 

package com.bean;

public class HelloBean implements Hello {

	private String name;
	
	public void hello() {
		
		System.out.println("hello,"+name);
	}

	public void setName(String name) {
		this.name = name;
	}

}

 

 編寫 bean-config.xml配置文件

<?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-2.0.xsd">

	<bean id="hello" class="com.bean.HelloBean">
		<property name="name">
			<value>tom</value>
		</property>
	</bean>
	
</beans>

 

OK!測試一下：編寫 Test類

package com.test;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.FileSystemXmlApplicationContext;

import com.bean.Hello;

public class Test {

	public static void main(String[] args) {
		ApplicationContext context = new FileSystemXmlApplicationContext("src/bean-config.xml"); 
		
		Hello hello = (Hello)context.getBean("hello");
		hello.hello();
	}

}

 

最後執行Test類運行程序！
