创建IInterface
IOneInterface
package com.spring.ioc.interfaces;
public interface IOneInterface {
public void say(String arg);
}
创建实现类
IOneInterfaceImpl
package com.spring.ioc.interfaces;
public class IOneInterfaceImpl implements IOneInterface {
@Override
public void say(String arg) {
System.out.println("ServiceImpl say: " + arg);
}
}
