如何从 Spring 应用程序中的 URL 获取延续映射？

Question

I have this spring application where I want to get the values from a URL, for example:

The url send to the spring application is www.example.com/app/account/register . How do I get the /register part after /account when my code looks like this.

For this example I used /register but this can be /login , /something as well.

@RestController
@RequestMapping("/app")
public class MainController {

    @RequestMapping(value = "/account")
    public boolean AccountServer(@RequestHeader HttpHeaders httpHeaders, @RequestBody Map<String, String> payLoad){
        return true;
    }
}

Answer 1

You can use the @PathVariable annotation to get the value.

@RestController
@RequestMapping("/app")
public class MainController {

    @RequestMapping(value = "/account/{operation}")
    public boolean AccountServer(@RequestHeader HttpHeaders httpHeaders,
                                 @RequestBody Map<String, String> payLoad,
                                 @PathVariable("operation") String operation){
  
        return true;
    }
}

Use UriComponentsBuilder as a parameter, it will be injected by Spring and initialized with current URI. You can then convert to UriComponents UriComponents to query the path.

@RestController
@RequestMapping("/app")
public class MainController {

    @RequestMapping(value = "/account")
    public boolean AccountServer(UriComponentsBuilder builder, @RequestHeader HttpHeaders httpHeaders, @RequestBody Map<String, String> payLoad){
        List<String> pathSegments = builder.build().getPathSegments();
        ...
        return true;
    }
}
