类 HandlerTypePredicate

java.lang.Object

cn.taketoday.web.handler.method.HandlerTypePredicate

所有已实现的接口:

Predicate<Class<?>>

public final class HandlerTypePredicate
extends Object
implements Predicate<Class<?>>

A Predicate to match request handling component types if any of the following selectors match:

• Base packages -- for selecting handlers by their package.
• Assignable types -- for selecting handlers by super type.
• Annotations -- for selecting handlers annotated in a specific way.

Composability methods on Predicate can be used :

 Predicate<Class<?>> predicate =
                HandlerTypePredicate.forAnnotation(RestController.class)
                                .and(HandlerTypePredicate.forBasePackage("org.example"));
