如何将springrest控制器从springhateoas0.x迁移到1.x？

我试图在一个定制的rest控制器类中重新创建springdatarest控制器的功能，这样我就可以得到hal格式的json并能够使用投影。现在，我可以在springboot1.5.17中使用以下代码来实现它。

@RequestMapping(method = GET, value = "students/fetchProfile")
public @ResponseBody
ResponseEntity<?> fetchStduentProfile(@RequestParam(required = true) String idNumber,
                                      PersistentEntityResourceAssembler resourceAssembler) {

    Student student = studentHandler.fetchStudent(idNumber);

    if (student != null) {
        return ResponseEntity.ok(resourceAssembler.toResource(student));
    } else {
        return new ResponseEntity<>(null, HttpStatus.NOT_FOUND);
    }
}

但一旦我升级到SpringBoot2.3.8，我就会得到一个httpmessagenotwritableexception

现在我知道springhateoas有了很大的变化，但是我不知道如何将这个控制器迁移到新的hateos类中。我甚至尝试过resourceSassembler.tomodel（），它产生了相同的异常。
那么，如何使这个控制器与新版本的springhateoas一起工作，以便获得hal格式的json并使用投影参数呢？
