1、结构图

2、class文件

MyIoc.java

package com.zbb.ioc;

public class MyIoc {
    MyService myService;
    public void ioc(){
        myService.service();
    }
    /*public MyIoc(MyService myService) {
        super();
        this.myService = myService;
    }*/
    public MyService getMyService() {
        return myService;
    }
    public void setMyService(MyService myService) {
        this.myService = myService;
    }
    
}

MyService.java

package com.zbb.ioc;

public class MyService {
public void service(){
    System.out.println("service");
}
}

MyTest.java

package com.zbb.ioc;

import org.springframework.context.support.ClassPathXmlApplicationContext;

public class MyTest {

    /**
     * @param args
     */
    public static void main(String[] args) {
        // TODO Auto-generated method stub
        ClassPathXmlApplicationContext classPathXmlApplicationContext = new ClassPathXmlApplicationContext("applicationContext.xml");
        MyIoc bean = (MyIoc)classPathXmlApplicationContext.getBean("myIoc");
        bean.ioc();
    }
    
}

 

3、配置文件

applicationContext.xml

    <!-- 构造器注入 -->

        </constructor-arg>
    </bean>
     -->
     <!-- setter方法注入 -->
     <bean id="myIoc" class="com.zbb.ioc.MyIoc" >
         <property name="myService" >
