咸鱼界的希望 虽然在各位回答之前我已经解决了问题,但是,你的回答是正确的,这80c应该给你!
一年多之前 回复

@SpringBootApplication
@EnableDiscoveryClient
@EnableFeignClients

把eureka启动起来 ,然后通过浏览器查看,一般是127.0.0.1:8761,在然后把 这几个注解注解放上面试试!具体你的代码,我也不知道!不过你可以试试!

是不是包冲突呀?去掉com.google.common.collect.MapMaker.keyEquivalence的这个包试一下
可以参考下面配置springcloud

spring微服务调用,没有注册中心也能用吗?
几个spring微服务的问题,请指教: 1、springboot开发用RestTemplate和feign方式,如果没有部署注册中心,也可以调用吧,也可以分布式部署微服务?那么很多场景下用户不需要对服务调用进行细粒度管控,是否可以不部署注册中心? 2、如果部署了注册中心如Eureka,是否所有controller都会被注册?注册中心会记录服务的调用情况包括日志等,那么正常从浏览器和APP发起的调用也会被记录吗? 3、服务提供者和消费者都要注册到注册中心,那么从浏览器和APP发起的调用应该没有注册消费者吧?这样注册中心的服务调用管理并不全面吧?是只包括微服务之间的调用吧?是否应只注册需要被其它微服务调用的controller而不是全部? 4、服务调用好像都是调用controller,能否调用其它微服务应用的service层?controller通常是为前端调用设计的,参数是DTO,而service的参数是DO|PO,在写业务时,可能更多使用后者。 5、用RestTemplate调用服务时,@LoadBalanced注解可实现负载均衡,如果没有部署注册中心,调用时直接写的服务方地址,怎么可能实现负载均衡呢?是否@LoadBalanced必须和注册中心一起用?没有注册中心的情况下如果一个微服务部署多个实例,我们是在nginx中配置集群的,调用地址就是集群的域名,即负载均衡是由nginx实现的,spring的负载均衡是由什么实现的?
springcloud 服务注册与发现的理解
假如一个系统我有三个服务 :服务A,  服务B, 服务C, 每个服务都有三个实例组成集群, 是不是每个服务的集群都要至少单独创建一个eureka server来给每个实例注册信息,如果这样都话,三个服务各自的eureka server之间如何同步各自的服务列表? 不知道这样理解对不对,还是说三个服务集群只需共用一个eureka server就行了,不用单独创建各自的eureka server,那么这样的话, 各自服务的eureka client集群如何创建?

SpringCloud将服务提供者注册到Eureka中,服务消费者怎么知道服务提供者具体提供的接口(方法)有哪些?
(新手问题)如题,网上看过部分SpringCloud的文章都提到了将一个微服务注入到Eureka中,然后服务消费者使用Feign或rest+ribbon调用服务提供者的具体接口进行消费。 但是其中有一个比较关键的问题好像都没有提到(个人理解为应该是过于简单,懒得说了),就是: 如果一个服务提供者,提供了多个接口(如:getUser()、getRole()...),那么服务消费者是怎么知道有这些方法(接口)的呢?因为有可能不同的微服务是由不同的人开发的,难道要靠文档传播? 还望不吝赐教。

Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它
程序员必须掌握的核心算法有哪些?

比特币原理详解
一、什么是比特币 比特币是一种电子货币,是一种基于密码学的货币,在2008年11月1日由中本聪发表比特币白皮书,文中提出了一种去中心化的电子记账系统,我们平时的电子现金是银行来记账,因为银行的背后是国家信用。去中心化电子记账系统是参与者共同记账。比特币可以防止主权危机、信用风险。其好处不多做赘述,这一层面介绍的文章很多,本文主要从更深层的技术原理角度进行介绍。 二、问题引入  假设现有4个人
程序员接私活怎样防止做完了不给钱?
首先跟大家说明一点,我们做 IT 类的外包开发,是非标品开发,所以很有可能在开发过程中会有这样那样的需求修改,而这种需求修改很容易造成扯皮,进而影响到费用支付,甚至出现做完了项目收不到钱的情况。 那么,怎么保证自己的薪酬安全呢? 我们在开工前,一定要做好一些证据方面的准备(也就是“讨薪”的理论依据),这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发
