【spring教程之十】spring注自动检测标注bean

1、该章主要讲解，不在xml文件中，手动的配置每个bean文件，而是通过统一自动检测的方法，主要就是在spring的配置文件加上一句话

<context:component-scan base-package="com.test.pro"></context:component-scan>

2、xml配置文件

<context:annotation-config></context:annotation-config><!-- 自动装配 -->
 
		<context:component-scan base-package="com.test.pro"></context:component-scan>

package com.test.pro;

import org.springframework.stereotype.Component;


@Component("piano")
public class Instrument {
	private String name="test";

	public String getName() {
		return name;
	}

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

package com.test.pro;

import javax.inject.Inject;

import org.springframework.stereotype.Component;


@Component
public class Singer {
	@Inject  /*这个地方加上注解，会自动注入*/
	private Instrument piano;

	public void saying()
	{
		System.out.println(piano.getName());
	}
}

package com.test.pro;

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

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		ApplicationContext ctx=new ClassPathXmlApplicationContext("spring.xml");
		Singer singer=(Singer)ctx.getBean("singer");
		singer.saying();

		
	}
	
	

}
