kandi X-RAY | springcloud Summary

springcloud is a Java library typically used in Architecture, Microservice, Spring Boot, Spring applications. springcloud has no bugs, it has no vulnerabilities, it has build file available and it has low support. You can download it from GitHub.

由于hystrix 篇幅较大,故单独成文,请见: Spring Cloud Hystrix 断路器. Feign 内部集成了Ribbon和Hystrix 先后启动生产者spring-cloud-04-feign-provider 、消费者spring-cloud-04-feign-consumer 调用消费端API (带有Hystrix降级) 注意:在写断路器的实现HelloFeignClientHystrixFallback时,不要忘了把它注入到spring容器中。. 1.启动两个服务 spring-cloud-05-hello-service spring-cloud-05-luck-service 2.启动网关 spring-cloud-05-gateway 3.确认两服务一网关都已开启 启动之后访问会发现返回了git-dev 。正好是evn-dev.properties中的内容 3. 动态刷新:若更改了github上的配置文件信息,需要不重启服务来刷新时,需要用post方式请求服务端的refresh接口

            SpringCloud 2020.0.2 upgrade generates testing error
            Asked 2021-Apr-27 at 10:44

            I'm trying to upgrade a project from SpringCloud BOM 2020.0.1 to 2020.0.2

            When I change the BOM and re-build, I get an error in JUnit tests, saying that the new parameter spring.config.import is not set for configserver.

            This project is not a ConfigServer, neither use ConfigServer (commented config client)

            This is the reported error in tests contextLoads()

            I have noted the same problem after upgrading to SpringCloud 2020.0.2

            Adding spring.cloud.config.enabled=false in the tests solved the issue.

            What version are you using?

            In 3.1, autoCommitOffset was deprecated in favor of setting the ackMode (to manual in this case); however, it looks like autoCommitOffset is now completely ignored rather than deprecated.

            This looks like Inbound Rules issue. In the AWS tutorial that uses a web application that uses AWS RDS, Inbound Rules are mentioned. You need to make sure the IP address of the Elastic Beanstalk instance is specified. If you do not do this, then the connection does not work.

            Here is the AWS RDS tutorial that discusses this subject matter:

            bootstrap.yml configuration not processed anymore with Spring Cloud 2020.0
            Asked 2020-Dec-25 at 04:28

            In my Spring Boot project, I defined 4 profiles

            1. demo
            2. dev
            3. test
            4. prod

            properties in YAML files will be replaced by HashiCorp Vault properties during startup. For this, I use Spring Cloud Vault library. Everything works as expected in Spring Boot 2.3.x

            When I try to upgrade the project to Spring Boot 2.4.0 with Spring Cloud Vault 3.0.0-SNAPSHOT version, the properties are not being replaced




            Answered 2020-Nov-30 at 18:57

            As pointed put by Nicoll, With Spring Cloud Vault 3.0 and Spring Boot 2.4, the bootstrap context initialization (bootstrap.yml, bootstrap.properties) of property sources was deprecated. This can be fixed in one of the 2 ways

            1. Use Spring Boot 2.4.0 Config Data API to import configuration from Vault
            2. Enable the bootstrap context either by setting the configuration property spring.cloud.bootstrap.enabled=true or by including the dependency org.springframework.cloud:spring-cloud-starter-bootstrap

            1. Use Spring Boot 2.4.0 Config Data API

            Move bootstrap.yml configuration to application.yml and define spring.config.import to import all profiles. And it looks like below

            Spring Cloud Config Client is not fetching automatically configuration from server
            Asked 2020-Nov-21 at 00:47

            I am implementing Spring Cloud config, but the clients are not fetching the config automatically... When I start up my client gets the data from the server properly, but never retrieves it again.

            This is my CloudConfig Server.



            Answered 2020-Nov-21 at 00:47

            if you want your config to be refresh you have to use @RefreshScope spring doc the config won't get update by magic himself because you call @Scheduled.

            But base on how you fetch the value in Configuration component they might be limitation and @RefreshScope will not work refreshscope

            I suggest create a bean a @ConfigurationProperties and annotate with @RefreshScope when you hit from actuator endpoint /refresh everything should update or maybe combination of @Schedule you might achieved what you want
