Spring Boot应用程序可以向自身发出HTTP请求吗？

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

@SpringBootApplication
@RestController
public class MyApplication {

    @Autowired
    private RestTemplate restTemplate;

    public static void main(String[] args) {
        SpringApplication.run(MyApplication.class, args);
    }

    @GetMapping("/example")
    public String example() {
        ResponseEntity<String> response = restTemplate.getForEntity("http://localhost:8080/api/data", String.class);
        return response.getBody();
    }
}
