Can DTOs be spring managed beans? [closed]

问题:

I am using spring 3.0.

I have few DTOs. Can I declare them as spring beans? If so what should be the bean scope?

回答1:

Usually, DTOs instantiation is not managed by spring (for instance Hibernate often instantiates DTOs).

Spring does have a prototype scope where a new object is created each time you lookup the object from the ApplicationContext. This scope is useful when you want to define default values in spring config.

See the documentation on prototype scope, here.
