<!--
bean的scope属性为singleton
当scope="singleton"时，无论这个bean被引用(获取)多少次都将指向同一个地址也就是同一个对象
可省略不写，因为此作用域为spring的默认作用域
-->
<bean id="singletonBean" class="com.spring.bean.scope.Scope" scope="singleton"></bean>
<!--
bean的scope属性为prototype
当scope="prototype"时，效果：每一次被引用(获取)的bean都被重新创建，也就是每当被引用时存储在内存中的位置都不同，
场景：用在需要保持会话或一个实例被持续操作的时候
-->
