1.写需要注解注入的类:

Propertie.java



package study;

public class 
Propertie {

    public 
void show() {

      
  System.out.print("我是注解注入的!");

  
  }

}

2.Person接口:



package study;
public interface Person {
  
   public void 
output();
 }

3.Chinese实现Person接口:



package study;
//必要的包
import javax.annotation.Resource;

public class 
Chinese implements Person {
    
    //注解注入符合@Resource
    
@Resource private Propertie p;
  
  private String name;
    
    public void output() {
        
p.show();
    }
}

4.测试类TestPerson.java



package study;

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

public class 
TestPerson {

    /**
    
 * @param args
     */
    public static 
void main(String[] args) {
    
    // TODO Auto-generated method 
stub
        ApplicationContext ctx = 
new ClassPathXmlApplicationContext("bean3.xml");
        Person p 
= (Person) ctx.getBean("chinese");
        
p.output();
    }

}

5.bean3.xml配置文件
