public @Interface Controller

Declares a method as a controller. If declared at the type level, it applies to all methods in the type.

A controller method that returns void is required to be annotated with View. A controller method can return a view path as a java.lang.String or a jakarta.ws.rs.core.Response. If a controller returns null and it is annotated with View, then the value of this annotation is used as a default.

Example:

    @Controller
    public String sayHello() {
        return "hello.jsp";
    }
