原因是因为这里你不能直接访问地址，需要把地址改成你所调用的ur在eureka上注册的application.name

下面这张是注册中心的

下面是配置文件中的

将代码修改为如下，就可以访问了

因为ribbon的作用是负载均衡，那么你直接使用ip地址，那么就无法起到负载均衡的作用，因为每次都是调用同一个服务，当你使用的是服务名称的时候，他会根据自己的算法去选择具有该服务名称的服务

浅析springcloud 整合 zipkin-server 内存日志监控

Zipkin Zipkin是一款开源的分布式实时数据追踪系统(Distributed Tracking System),基于 Google Dapper的论文设计而来,由 Twitter 公司开发贡献.其主要功能是聚集来自各个异构系统的实时监控数据. Zipkin主要包括四个模块 - Collector 接收或收集各应用传输的数据 - Storage 存储接受或收集过来的数据,当前支持Memory,MySQL,Cassandra,ElasticSea
SpringCloud服务注册和发现组件Eureka

本篇文章,我们来讲解springcloud的服务注册和发现组件,上一章节我们讲解了如何搭建springcloud的多模块项目,已经新建了springcloud-eureka-server,springcloud-eureka-client两个模块,本章节就在这基础上直接使用. 想要了解的请参考:一起来学Spring Cloud | 第一章 :如何搭建一个多模块的springcloud项目一.Eureka简介: 1.1 什么是eureka Eureka是一个基于REST的服务,主要用于AWS云中
SpringCloud实现Eureka服务注册与发现

GitHub地址:https://github.com/yudiandemingzi/spring-cloud-study 一.Eureka概述 1.Eureka特点 (1) Eureka是一个基于REST的服务,用于定位服务,以实现云端中间层服务发现和故障转移. (2) Eureka 主管服务注册与发现,在微服务中,以后了这两者,只需要使用服务的标识符(==就是那个在每个服务的yml文件中取得服务名称==), 就可以访问到服务,不需要修改服务调用的配置文件. (3) Eureka遵循AP原则(
SpringCloud微服务之Config知识总结

一.什么是Spring Cloud Config? Spring Cloud Config 可以为微服务架构中的应用提供集中化的外部配置支持,它分为服务端和客户端两个部分. Spring Cloud Config 服务端被称为分布式配置中心,它是个独立的应用,可以从配置仓库获取配置信息并提供给客户端使用. Spring Cloud Config 客户端可以通过配置中心来获取配置信息,在启动时加载配置. Spring Cloud Config 的配置中心默认采用Git来存储配置信息,所以天然就支持
基于SpringCloud手写一个简易版Sentinel

Sentinel 是什么? 随着微服务的流行,服务和服务之间的稳定性变得越来越重要.Sentinel 以流量为切入点,从流量控制.熔断降级.系统负载保护等多个维度保护服务的稳定性. 不可否认的是,Sentinel功能丰富,并且在提供好用的dashboard提供配置,但是Sentinel在集成到项目中时需要引入多个依赖,并且需要阅读相关文档,以及dashboard中的相关配置才可以接入到项目中,这个过程还是较为复杂的. 如果我们的项目并不需要这么多的功能,只是需要当某个方法或者某个功能发生异常的时
SpringCloud整合分布式服务跟踪zipkin的实现

1.zipkin zipkin是Twitter的一个开源项目,它基于Google Dapper实现.我们可以使用它来收集各个服务器上请求链路的跟踪数据,并通过它提供的REST API接口来辅助我们查询跟踪数据以实现对分布式系统的监控程序,从而及时地发现系统中出现的延迟升高问题并找出系统性能瓶颈的根源.除了面向开发的API接口之外,它也提供了方便的UI组件来帮助我们直观的搜索跟踪信息和分析请求链路明细,比如:可以查询某段时间内各用户请求的处理时间等. zipkin的架构图如下: 由上面的架构图可以
