Currently, I'm building urls using string concatenation.

String url = "http://localhost:8080/bo/" + docId;

HttpEntity<String> httpEntity = this.handleJWT();

restTemplate
    .exchange(
        url,
        HttpMethod.DELETE,
        httpEntity,
        Void.class
    );

Is there more elegant to build rest url using java?

You can also use UriComponentsBuiler

String url = "http://localhost:8080/bo/{docId}"
UriComponentsBuilder
            .fromHttpUrl(url)
            .buildAndExpand(docId)
            .toUriString();

And url should be injected from properties.

How do you design a great REST API? Build a Standard Organization-Wide REST API Framework. The typical frameworks that are used to build RESTful web services in the Java world, are Spring MVC, import org.springframework.util. How I Built a Smart Coffee Machine With the Cloud Wallet API.

You could do it this way:

String url = "http://localhost:8080/bo/{docId}";

restTemplate
.exchange(
    url,
    HttpMethod.DELETE,
    httpEntity,
    Void.class,
    docId
);

Now, look that the SpringBootRest2Application.java file, which is created by import java.util. In spring's approach to build a RESTful web services, HTTP requests are handled @RequestMapping(method = RequestMethod. Follow step 10 and insert the below URL in the address box and click OK. You create a web service class with annotations that converts your methods into callable REST URLs. Finally, you package your Java REST application into a single portable JAR file which can be executed pretty much anywhere. Grizzly Web Server. Project Grizzly is a pure Java web service built using the NIO API.

Yes, there is. Hard-coding URLs like you do is certainly not recommended.

Spring Boot Rest allows you to map requests to URLs via annotations like @RequestMapping.

In your case a method signature in a with @RestController annotated class could like this:

@RequestMapping(value = "/bo/{docId}", method = RequestMethod.DELETE)
public void request(@PathVariable("docId") int docId){
   ...
}

E.g. entering localhost:8080/bo/123 in your browser would then result in a method call with "123" being the passed parameter.

With this layout you can trigger method calls pretty conveniently. I recommend you to go through this Spring Boot Rest tutorial. It provides a good starting point on how to properly set up a Spring Boot application with restful interaction.
