如何获得spring boot控制器端点的完整url？

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.support.ServletUriComponentsBuilder;

@RestController
@RequestMapping("/api")
public class MyController {

    @GetMapping("/endpoint")
    public String myEndpoint() {
        String baseUrl = ServletUriComponentsBuilder.fromCurrentContextPath().build().toUriString();
        String endpointUrl = ServletUriComponentsBuilder.fromCurrentRequest().build().toUriString();

        return "Base URL: " + baseUrl + "\nEndpoint URL: " + endpointUrl;
    }
}
