IntelliJ在说：不合适的阻塞方法调用

如何重构此方法以通过此标准？

public List<User> getallUsers(String name) {
        Type userList = new TypeToken<List<User>>() {
        }.getType();

        try {
            RestTemplate restTemplate = new RestTemplate();
            ResponseEntity<String> responseEntity
                    = restTemplate.getForEntity(host,String.class);
            Gson gson = new GsonBuilder().create();


            List<User> users = gson.fromJson(responseEntity.getBody(),userList );

            return users == null ? new ArrayList<>() : users;

        } catch (HttpClientErrorException | HttpServerErrorException e) {
            return new ArrayList<>();
        }
    }
