In my current setup, I have eureka server config server (running on random ports) zuul gateway server and 2 instances of a service (running on random ports) All these instances are successfully register with Eureka. When all the services are running, The load balancing is done properly through zuul without any issues. when an instance is killed, Zuul is still trying to fulfil the request using the same service which is down. However if waited till the eureka

I have one gateway service with @EnableZuulProxy and a book-service with a status method. Via configuration I can emulate work on the status method by sleeping a defined amount of time. The Zuul route is simple zuul.routes.foos.path=/foos/** zuul.routes.foos.serviceId=reservation-service I run two instances of the book-service . When I set the sleeping time below the Hystrix timeout threshold (1000ms) I can see requests going to both instance of the book services. This

My zuul (edge) service is published in the 8765 port and my organizations service is in the 8083 one. Everything goes smoothly when I access the application with no security, http://localhost:8765/organization/organizations returns the JSON with all the organizations. However, now I want to integrate a Keycloak SSO (OAuth2) server for authorization purposes. I have added the Spring Security adapter in my

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I want to introduce Zuul through Spring Cloud as an API Gateway in front of a few services. I have some design doubts around Authentication. The Authentication would be handled by Spring Security, which comes before Zuul in the servlet filter chain. My concern: the Gateway would sit in front of many services some services may expose endpoints which do not require authentication some services may expose endpoints which need a Session Id and some with a token", an arbitrary opaque value (for example downloading a file if you know a "hard to

sprignclou的zuul的实战

http://www.scienjus.com/api-gateway-and-netflix-zuul/ 就像上图中所描述的一样,Zuul 提供了四种过滤器的 API,分别为前置(Pre)、后置(Post)、路由(Route)和错误(Error)四种处理方式。 一个请求会先按顺序通过所有的前置过滤器,之后在路由过滤器中转发给后端应用,得到响应后又会通过所有的后置过滤器,最后响应给客户端。在整个流程中如果发生了异常则会跳转到错误过滤器中。 一般来说,如果需要在请求到达后端应用前就进行处理的话,会选择前置过滤器,例如鉴权、请求转发、增加请求参数等行为。在请求完成后需要处理的操作放在后置过滤器中完成,例如统计返回值和调用时间、记录日志、增加跨域头等行为。路由过滤器一般只需要选择 Zuul 中内置的即可,错误过滤器一般只需要一个,这样可以在 Gateway 遇到错误逻辑时直接抛出异常中断流程,并直接统一处理返回结果。 原文: https://www.cnblogs.com/fengli9998/p/9353817.html

zuul 是netflix开源的一个API Gateway 服务器, 本质上是一个web servlet应用。 Zuul 在云平台上提供动态路由,监控,弹性,安全等边缘服务的框架。Zuul 相当于是设备和 Netflix 流应用的 Web 网站后端所有请求的前门。 Gateway(网关)是微服务架构的不可获取的一个部分,Gateway为客户点提供了统一访问的入口,Netflix Zuul是 Spring Cloud默认使用的Gateway组件 Zuul是Netflix出品的一个路由和服务端的负载均衡组件 1、打开idea新建springBoot项目 创建完成项目后,可以发现pom.xml文件中的这两个依赖 <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-eureka-client</artifactId> </dependency> <dependency> <groupId>org.springframework.cloud</groupId> <artifactId>spring-cloud-starter-netflix-zuul</artifactId> </dependency> 2、在项目的主类上添加注解

spring cloud 项目在feign client 调用时候用到标题错误 服务提供者 @RequestMapping(value="/getMessageqqtest",method= RequestMethod.POST) public String TestMessage2(Integer num) { return mrc.getMessage(num+2000); } feign client 调用方 @FeignClient(value = "horus-zuul-server") public interface MessageResultFacade{ @RequestMapping(value = "/chaosclient-service-provider/getMessageqq", method = RequestMethod.POST, produces = "application/json; charset=UTF-8") String getMessage(Integer num); } 经过分析 发现是参数没有传过去 参数传到控制器端为null 参考网上思路 要加上requestparam 修改如下 提供者 @RequestMapping(value="/getMessageqqtest1",method= RequestMethod.POST
