java Reformation onFailure（）方法调用次数

Question

我正在使用改型，并为远程API调用失败的场景实现了重试逻辑。我创建了以下类，我从以下线程中获取： Retrying the request using Retrofit 2

public abstract class CallbackWithRetry<T> implements Callback<T> {

    private static final int TOTAL_RETRIES = 3;
    private int retryCount = 0;

    @Override
    public void onFailure(Call<T> call, Throwable t) {
        if (retryCount++ < TOTAL_RETRIES) {
            log.info("Retrying... (" + retryCount + " out of " + TOTAL_RETRIES + ")");
            retry(call);

            try {
                Thread.sleep(10000);
            } catch (InterruptedException e) {
                e.printStackTrace();
            }
        }
    }

    private void retry(Call<T> call) {
        call.clone().enqueue(this);
    }
}

我是这样用的：

    call.enqueue(new CallbackWithRetry<String>() {
        @Override
        public void onResponse(Call<String> call, Response<String> response) {
            log.info("Response received from remote API: {}", response.body());
        }
    });

它按预期工作，但我在日志中看到以下内容，我试图理解原因：

onFailure方法是否通过改造执行/调用了5次？为什么
