public Interface BeanExpressionResolver

Imports
org.springframework.beans.BeansException, org.springframework.lang.Nullable
Strategy interface for resolving a value by evaluating it as an expression, if applicable.

A raw org.springframework.beans.factory.BeanFactory does not contain a default implementation of this strategy. However, org.springframework.context.ApplicationContext implementations will provide expression support out of the box.
