Best way to propagate credentials between micro services using spring-session

由 ￡可爱￡侵袭症＋ 提交于 2019-12-07 08:45:49
问题 We are using an architecture very similar to the one described in this great guide on spring.io. Our gateway handles authentication, and sessions are stored in Redis using spring-session. Endpoints of our micro services are secured and also use spring-session. In a micro service I need to call an endpoint of another micro service. I get the URL easily through the discovery client, but I need to provide credentials and I'm not sure of the best way to achieve that. I am thinking about getting

Authentication issue with repo accessed from Spring Cloud Config Server hosted on GitHub

问题 I'm hosting a configuration in a repo on GitHub. If I keep the repo public all's good, but if I make it private I face: org.eclipse.jgit.errors.TransportException: https://github.com/my-user/my-repo: Authentication is required but no CredentialsProvider has been registered the property I use to target the repo is spring.cloud.config.server.git.uri=https://github.com/my-user/my-repo What should I do to configure this properly with the private repo, thanks 回答1: you need to add the spring.cloud

Spring-Cloud系列第4篇：spring-cloud-Hystrix

由 大憨熊 提交于 2019-12-07 01:05:36
自学spring-cloud系列，越来越感觉spring-cloud很强大！ 主要分为以下几篇： spring-cloud-config: 分布式配置管理 spring-cloud-eureka: 服务注册与发现 spring-cloud-eureka-consumer: 远程服务调用和及其负载均衡 spring-cloud-Hystrix: 熔断器保证服务高可用 spring-cloud-config-eureka-ribbon: 分布式配置管理的高可用 spring-cloud-bus: 配置信息的实时更新 spring-cloud-zuul: 网关基础服务 熔断器介绍 说起springcloud熔断让我想起了去年股市中的熔断，多次痛的领悟，随意实施的熔断对整个系统的影响是灾难性的，好了接下来我们还是说正事。 雪崩效应 在微服务架构中通常会有多个服务层调用，基础服务的故障可能会导致级联故障，进而造成整个系统不可用的情况，这种现象被称为服务雪崩效应。服务雪崩效应是一种因“服务提供者”的不可用导致“服务消费者”的不可用,并将不可用逐渐放大的过程。 如果下图所示：A作为服务提供者，B为A的服务消费者，C和D是B的服务消费者。A不可用引起了B的不可用，并将不可用像滚雪球一样放大到C和D时，雪崩效应就形成了。 熔断器（CircuitBreaker） 熔断器的原理很简单，如同电力过载保护器

Cannot disable Spring Cloud Config via spring.cloud.config.enabled:false

由 孤街醉人 提交于 2019-12-06 21:36:03
问题 Let me preface this by saying that I'm not using Spring Cloud Config directly, it is transitive via Spring Cloud Hystrix starter. When only using @EnableHystrix , Spring Cloud also tries to locate a configuration server, expectedly unsuccessfully, since I'm not using one. The application works just fine, as far as I can tell, but the problem is in the status checks. Health shows DOWN because there is no config server. Browsing the source of the project, I'd expect spring.cloud.config.enabled
