一：

1.框架

　　

 

2.pom

　　需要spring core与spring context。

3.接口HelloWorld

1 package com.it.service;2 3 public interface HelloWorld {4     public void sayHello();5 }

 

4.实现类

1 package com.it.service;2 3 public class SpringHelloWorld implements HelloWorld {4 5     public void sayHello() {6         System.out.println("say hello");7     }8 }

 

5.bean

1 package com.it.bean; 2  3 import com.it.service.HelloWorld; 4  5 public class HelloWorldService { 6     private HelloWorld helloWorld; 7  8     public HelloWorldService() { 9 10     }11 12     public void setHelloWorld(HelloWorld helloWorld) {13         this.helloWorld = helloWorld;14     }15 16     public HelloWorld getHelloWorld() {17         return this.helloWorld;18     }19 }

 

6.运行main

1 package com.it.main; 2  3 import com.it.service.HelloWorld; 4 import com.it.bean.HelloWorldService; 5 import org.springframework.context.ApplicationContext; 6 import org.springframework.context.support.ClassPathXmlApplicationContext; 7  8 public class HelloMain { 9     public static void main(String[] args) {10 11         ApplicationContext context = new ClassPathXmlApplicationContext("beans.xml");12 13         HelloWorldService service = (HelloWorldService) context.getBean("helloWorldService");14 15         HelloWorld hw= service.getHelloWorld();16 17         hw.sayHello();18     }19 }

 

7.beans.xml
