实施AsyncCacheApi Play 2.7

Question

 public static Company getCompany() {
        Company company = cache.getOrElseUpdate(session("userSchema") + "c", () -> {
            return overrideCompanyCache();
        }, 300);
        if (company != null) {
        }
        return company;
    }

抛出错误：不存在类型变量T的实例，因此Company符合CompletionStage
