Spring Expression Language (SpEL) 6.1.4 · org.springframework.expression.ConstructorResolver

A constructor resolver attempts to locate a constructor and returns a ConstructorExecutor that can be used to invoke that constructor.

The ConstructorExecutor will be cached, but if it becomes stale the resolvers will be called again.
