Hybris中的商业外观范围
[英]scope of commerce facade in hybris
问题描述
why is the scope of commerce facades marked prototype by default ? 
为什么默认情况下将商务外观的范围标记为原型？ Is it that we always need a new instance of the requested facade every time we refer it or am I missing something here while understanding the concept of commerce facades in hybris ? 是我们每次引用它时总是需要一个所请求的外观的新实例吗？还是我在理解hybris中的商业外观的概念时在这里遗漏了什么？

In commercefacades-spring.xml only some populators and some POJOs are marked prototype. 在commercefacades-spring.xml中，只有一些填充器和一些POJO被标记为原型。
The facades are still singletons since they are noting but special services. 外墙仍然是单例，因为它们只是特殊的服务。

Facades are singleton scoped beans by default. 外观默认情况下是单例作用域的bean。 There is no need to create a new instance of facade object on every request. 无需在每个请求上创建一个Facade对象的新实例。
