@Target(value=TYPE)

public @interface Controller

Indicates that an annotated class is a "Controller" (e.g. a web controller).

This annotation serves as a specialization of @Component, allowing for implementation classes to be autodetected through classpath scanning. It is typically used in combination with annotated handler methods based on the org.springframework.web.bind.annotation.RequestMapping annotation.
