当然，我们可以完全不使用显式的范围，只要能确保没有用不适当的类型来实例化类型参数。

Of course, we could simply leave off the explicit bound and just make sure that we never instantiate the type parameter with an inappropriate type.

隐式类装入发生在由于引用、实例化或继承导致装入类的时候(不是通过显式方法调用)。

Implicit class loading occurs when a class is loaded as result of a reference, instantiation, or inheritance (not via an explicit method call).

要想自动装配应用代码中实例化的实体，最简单也是最笨的办法就是通过RichDomainObjectFactory的方式显式进行自动装配。

The easiest but rather clumsy way to autowire entities that are instantiated in application code would be to autowire them explicitly by means of the RichDomainObjectFactory.
