BeanExpressionResolver (Spring Framework 5.2.12.RELEASE API)

所有已知实现类:
StandardBeanExpressionResolver
```
public interface BeanExpressionResolver
```
Strategy interface for resolving a value through evaluating it as an expression, if applicable.
A raw BeanFactory does not contain a default implementation of this strategy. However, ApplicationContext implementations will provide expression support out of the box.
