Class ServerlessMVC

java.lang.Object

org.springframework.cloud.function.serverless.web.ServerlessMVC

public final class ServerlessMVC
extends Object

Represents the main entry point into interaction with web application over light-weight proxy. After creating an instance via INSTANCE(Class...) operation which will initialize the provided component classes of your web application (effectively starting your web application less web server), you use service(HttpServletRequest, HttpServletResponse) operation to send request and receive a response.
