Hateoas java.lang.IllegalStateException：无法通过RequestContextHolder找到当前请求

Question

我正在使用Hateoas功能调用Controller的post方法url。但是当我尝试使用ControllerLinkBuilder类的linkTo方法时，我会遇到异常，如下所述：

Java类：

import static org.springframework.hateoas.mvc.ControllerLinkBuilder.linkTo;

import org.springframework.stereotype.Component;

@Component
public class CallController{  

    public String doThis()
    {  
        ManagementResource resource = new ManagementResource();
        resource.add(linkTo(DataController.class).withRel("postData"));
        return ""; 
    }

}  

控制器类

@Controller
@RequestMapping("/data")
public class DataController {

    @RequestMapping(method = RequestMethod.POST, value = "")
    public ResponseEntity<ManagementResource> postData(@RequestBody Data1 data) {
        RSResponse<Data1> response = new RSResponse<Data1>();
        response.setStatus(RSResponse.Status.SUCCESS);
        response.setData(data);
        return new ResponseEntity<ManagementResource>(HttpStatus.CREATED);
    }
}

如果有人对此有所了解，我在这里做错了，请告诉我。提前谢谢。
