解决方案：

是由于jar包冲突引起的。

1.5.9 pom依赖

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-feign</artifactId>
</dependency>

2.0.x pom 依赖

<dependency>
<groupId>org.springframework.cloud</groupId>
<artifactId>spring-cloud-starter-openfeign</artifactId>
</dependency>
修改一下配置文件！

之后updatemaven一下

如果上面方法还是不行就把本地下载好的jar包全部删除掉之后在下载jar包就可以了。

Java生鲜电商平台-SpringCloud微服务架构中网络请求性能优化与源码解析

Java生鲜电商平台-SpringCloud微服务架构中网络请求性能优化与源码解析说明:Java生鲜电商平台中,由于服务进行了拆分,很多的业务服务导致了请求的网络延迟与性能消耗,对应的这些问题,我们应该如何进行网络请求的优化与处理呢? 到底有没有一些好的建议与方案呢? 下面这个文章将揭晓上面的问题,让你对SpringCloud微服务网络请求性能有一个全新的认识. 目录简介 01.网络请求异常分类 02.开发中注意问题 03.原始的处理方式 04.如何减少代码耦合性 05.异常统一处理步骤 06

千万级调用量微服务架构实践

微服务架构在大型电商中的运用电商是促销拉动式的场景,也是价格战驱动的场景.618和双11都是典型的促销活动.其实都是在抢用户.扩市场占有率.在这样的场景之下,对秒杀.抢购是很热衷的玩法. 促销式的拉动对系统的挑战是什么呢? 可以从上图里看到:对高可用性的要求是非常高的,需要99.99%的高可用性.快速迭代对对系统容性的要求很高,从几万单变成几十万单.百万单,架构上不能影响快速迭代,所以有空中加油或者是高速公路换轮胎的说法. 另外,为了应对瞬间的海量访问(尤其是秒杀场景),系统需要高可伸缩(快速扩

开发者最佳实践日·第 13 期－实践微服务架构

随着Docker及以移动化浪潮的冲击,系统的架构与设计成为系统构建中重要环节,微服务架构这一全新的企业架构模式也越来越受到关注,使用容器技术实施微服务架构转变,如何更好的利用计算资源,以及更方便的维护越来越复杂的应用程序,微服务作为一种更灵活.可靠.开放的架构的应用实践也越来越多. 微服务架构如何让应用程序的代码库更加敏捷?如何快速迭代和扩充一个代码库并大幅提升开发者生产效率?微服务架构可以让开发团队在研发过程中更加的敏捷和灵活.想要知道更多关于微服务架构的知识,这一场沙龙你不可错过. 开发者最

你所不了解的微服务架构

一直以来,系统的架构设计是IT领域经久不衰的话题,也是构建每一个系统最核心且重要的部分之一.它决定了系统能否满足业务.技术.组织.灵活.可扩展性等多种要求,同时肩负起了解放程序员生产力的作用. 2016年底,由于业务的不断发展,我所在公司维护的项目也越来越"臃肿".随着无数个版本的迭代,以及开发人员的不断增加,开发效率越来越低,每次投产的人力成本和时间成本都逐渐增加,我们一直在思索如何能破局.评估了各种方案后,最终微服务进入了我们的视野. 谈到微服务,大家众说纷纭,但却很难有一个清晰的

细说微服务架构的优势与不足那点事

摘要: 一个微服务一般完成某个特定的功能,比如下单管理.客户管理等等.每一个微服务都是微型六角形应用,都有自己的业务逻辑和适配器.一些微服务还会发布API给其它微服务和应用客户端使用.其它微服务完成一个Web UI,运行时,每一个实例可能是一个云VM或者是Docker容器. 微服务正在博客.社交媒体讨论组和会议演讲中获得越来越多的关注,在Gartner的2014 Hype Cycle上它的排名非常靠前.同时,软件社区中也有不少持怀疑论者,认为微服务不是什么新东西.Naysayers认为这就是S
