@Service,@Resource和@Qualifier的简单使用
当一条业务线需要多种逻辑时，但是接口已经写好了，如果在接口上新增新的方法，务必使得实现该接口的类又要使用多余的方法，可以使用新的类继承老的类，重写该方法

pom文件依赖
对于两个不同的实现类实现了同一个接口，同时可以使用@Qualifier来匹配到我们需要的调用的实现类
其中@Service里面的双引号是给不同的实现类定义的不同的名字，类似xml文件中<bean id="">中的id一样
下面给出如何使用
根据业务需要不同的功能调用对应的接口下不同的实现类，其中引入的包路径是
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Qualifier;
