spring4 学习1 javaproject

jar包下载地址：

http://maven.springframework.org/release/org/springframework/spring/4.2.4.RELEASE/

  

 

   spring核心容器需要jar包5个，如果要通过在类上加注解的方式注入容器，则要添加spring-aop jar包

   下面是工程引入的jar包：

   

 源码如下：

 

package com.xx.demo;

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

public class ClientDemoClass {
	public static void main(String[] args) {
		 ApplicationContext context = new FileSystemXmlApplicationContext(   
	                "src/config/application-context.xml");   
		 DemoClass1 demo1 = (DemoClass1) context.getBean("demoClass1");  
		 demo1.print();
	}
}

 

 

package com.xx.demo;

import org.springframework.stereotype.Component;

@Component("demoClass1")
public class DemoClass1 {
	public void print(){
		System.out.println("这是DemoClass1");
	}
}
