Is the Rest Controller class singleton?

Question

I am learning Spring and Spring Boot. In my Spring boot app, I am using @RestController annotation for one of my classes which receives requests and processes them accordingly.

@RestController
public class SampleController {
......
}

I want to ask would this class annotated with @RestController be a singleton class? My thought is that this SampleController would also be a bean and since the default scope is Singleton, it would be a Singleton class. I want to ask whether I am thinking right.

Yes , seems you think right https://stackoverflow.com/questions/11508405/are-spring-mvc-controllers-singletons — Ali D.A., May 09 '20 at 08:53

Yes, you are right. Any bean you creating via annotations @Component, @Service, @Repository, @Controller, @RestController and @Bean of course by default have Singleton scope. Check Bean scope
