RestController

pom.xml

To implement a rest controller you need the following dependency in your pom.xml:

<dependencys>
    ...
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    ...
</dependencys>

Example implementation

A sample implementation for a simple RestController is shown below.

import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class ExampleController {

    @GetMapping(path = "/demo/ping")
    ResponseEntity<String> ping() {
        return ResponseEntity.ok("pong");
    }
}

The endpoint can be addressed with the following curl command:

curl localhost:8080/demo/ping
