Question

我在下面提供了一个REST端点

    @PutMapping("/calculateReward")
    public ResponseEntity<String> calculateReward(@RequestParam("userId") Long userId) {

        Optional<User> optional = userService.findById(userId);

        if (!optional.isPresent()) {
            return ResponseEntity.status(HttpStatus.NO_CONTENT).build();
        }

        User user = optional.get();

        double reward = user.getCurrentSteps() * Parameters.REWARD_PER_STEPS_EUR;

        RewardList list = new RewardList();

        list.setUser(user);
        list.setReward(reward);

        user.setCurrentSteps(0);
        user.setRewardLists(list);

        userService.save(user);
        rewardListService.save(list);

        JSONObject json = new JSONObject();

        double convertionRateToEuro = currencyMap.get(user.getCurrencyName());
        double rewardConverted = reward * convertionRateToEuro;

        json.put("name", user.getName());
        json.put("currency", user.getCurrencyName());
        json.put("reward", rewardConverted);

        return ResponseEntity.status(HttpStatus.CREATED).body(json.toString());
    }

ATM我进入另一个端点，需要从上面提供的端点获取奖励值。

    @PostMapping("/paypal/make/payment")
    public ResponseEntity<String> paymentUsingPaypal(@RequestParam("userId") Long userId) {

        Optional<User> optional = userService.findById(userId);

        if (!optional.isPresent()) {
            return ResponseEntity.status(HttpStatus.NO_CONTENT).build();
        }

        User user = optional.get();


        // How do I get the "reward" in double here?
    }

在第二种方法的末尾，如何从calculateReward方法中获得双倍的“奖励”？

Answer 1

如果是同一应用程序，为什么不直接调用：

nameOfController.calculateReward(userId);

如果无法调用该方法，则必须使用例如feign编写客户端。

从另一个呼叫REST端点
