parallelStream()并发远程调用服务导致异常_could not find class [org.springframework.boot.aut-优快云博客

问题描述

商城首页有许多商品组件、优惠券组件信息需要同步更新。比如：当时配置优惠券时，由于没有用户信息，默认都是未领取状态。当一个登录用户访问首页时，这时候首页配置的优惠券状态就要根据当前用户信息进行更新：已领取/未领取/已领完等。

由于组件更新都需要进行远程服务调用，商品最新价格需要远程调用商品服务，优惠券针对用户状态需要远程调用优惠券服务，如果首页配置的组件非常多，同步串行调用将非常耗时，首页加载速度非常慢，影响用户体验。

基于上述情况，为了提高首页加载速度，采用了并行请求模式。具体代码如下：

// itemList是组件对象列表，包括：商品组件、优惠券组件等
itemList.parallelStream().forEach(item -> {
	JSONObject listItem = (JSONObject) item;

	ParallelParam parallelParam = new ParallelParam(listItem, Objects.nonNull(user) ? user.getId() : null);
	itemConsumer.accept(parallelParam);
});

Consumer<ParallelParam> itemConsumer = parallelParam -> {
	// 如果是商品组件，更新商品信息
	if(goodsTypes.contains(parallelParam.item.getString("type"))) {
		goodsItemConsumer.accept(parallelParam);
	}
	
	// 如果是优惠券组件，则获取最新的个人-优惠券状态
	if("coupon".equals(parallelParam.item.getString("type"))) {
		couponItemConsumer.accept(parallelParam);
	}
};

// 在上述goodsItemConsumer和couponItemConsumer中均会远程调用对应的服务

这里顺便提一句咱们的部署方式，采用K8s+Docker容器的方式部署服务。服务部署完成后，在实际运行中出现异常：Could not find class [org.springframework.boot.autoconfigure.condition.OnPropertyCondition]，具体报错内容如下：
