Awesome Explanation .... In my company we are using the same technology. These videos helping me lot to understand the microservices cloud concept....!! Thanks
if you getting whitelabel error after configuring to git then I know that I'm posting this answer very very late. But, still posting it so that other folks can find this helpful. Now a days, default branch name of GitHub is "main", but Spring Cloud Config still looks for "master" as a label name. So, if you want to change the default behavior, you can always change the label name look up using below property in application.yml or application.properties: spring.cloud.config.server.git.default-label=main This worked very well for me. I'm using Spring Boot 2.3.6.RELEASE
Really thank. I thought it was too difficult but u make it clear. I have doubts about if I have multiple rest control then all the urls should added in the git repository?
Somehow refresh scope not refreshing properly.. whenever I chnages the provider url.. and chnaged same in properties file and when I add/chnaged something for the shake of devtools refreshing then only it is working .
Thank you for all the videos. You have made multiple videos around spring cloud, how to connect all these videos and do a project so that we are confident as a production ready developer. Kindly help if there is a overall video or course.
Sir i am facing problem with @refreshscope while setting the datasource. When i am adding @refreshscope in both class and method then after changing the profile from git repo it is changing the one database like if currently i am in devservice database then it is changing to prodservice but again when i am hitting the refresh endpoint it is not changing to devservice. I have also tried the spring bus but nothing is working. I think the problem is i am adding @Refreshscope at wrong place. But if i am removing the @Rscope annotation from method then i am getting an exception that my project is not connected with any database so for that i have moved datasource to the main method and autowired the class in which i am reading the properties using @Value both this is also not working but when i am adding @Rscope on datasource bean then it is changing the db connection for one environment as i said earlier. Please respond sir
Followed same code as yours..getting exception while starting insurance-client app...error is .. lang.illegalArguementException: could not resolve placeholder 'insurance.provider.url' in value "${insurance.provider.url}" .... Can you please help.
Hi sir, Thanks for the video. I have some doubts like, 1. Can we fetch property file from any other branch rather than master branch. 2. If we save a file in git and name it as "application.properties" or "our config service project name.properties" , it is fetching data from both for default profile. How to differentiate between them?
when i run insurance-client i got this error please solve if is possible?? No spring.config.import property has been defined Action: Add a spring.config.import=configserver: property to your configuration. If configuration is not required add spring.config.import=optional:configserver: instead. To disable this check, set spring.cloud.config.enabled=false or spring.cloud.config.import-check.enabled=false.

Awesome example. Ek doubt tha. In client you just declare String url with @Value(${insurance.provide.url}), ab this is read from config server. But how does it know that for "/getPlan" URI i have to hit this URL that i get from config server. What happens when you write a new URI in client same Controller class. Say "/secondApi", what happens in that case ?
No if you observe in yml file we are giving the link of git that's how it search application.yml and properties and map that value to property place holder
Nice explaination. I have one question. Could you please help to elaborate the differences between Netflix Eureka and Spring Cloud Config? This would help us understand the which should be used when?
Vivek very simple Both are having different purposes Spring cloud eureka is used to register your microservice where spring cloud config used to centralize common configuration accross all the microservice
Eureka is service discovery and Spring Cloud Config globally managing the configuration for multiple micro service with externalization, consistency and real time.
@@Javatechie Ok so can you put eureka configuration code in config server instead of inside the microservice instance? Suppose there is like 11 instances for a microservice and we changed the gateway server ip address, then we would have to make changes in each of those instances. So can Euraka pick up the gateway server's ip address from the configuration server via github repository?
Even if we add @refreshScope annotation ,we need to hit post with /actuator/refresh then only will take the changes from,is it's right na sir, please reply this
Guys if anyone working in 2.4 version please add below setup in the config client application application.properties file. spring.config.Import=optional:configserver:localhost:9898(give your config server port) Management.endpoints.web.exposure.include=*
Please, explain how to use a Private GitHub Repository. No client wants a Public Repository with Configurations. Even if they are encrypted. Please, help us with the Certificates recommended solution.
Once you commit in GIT, Your Config-Server will start providing the updated properties... @RefreshScope will make the variables as refreshable but unless you CALL THE ACTUATOR/REFRESH end-point they won't update in run-time. If you want that to happen try implementing ApplicationListeners in your @Configuration files.

If we are using spring cloud config then spring will read properties from git right? 1. Here my question is whether we will get same git repository Properties file data in Enviroment variable or we will get our project application.properties data in Enviroment variable.? Or both? 2 .In your application you have used @value annotation, if we will use Enviroment it will work or not?
Hi sir I have worked on this feature I am not getting updated value from properties until unless I refresh actuator but you are not doing any actuator refresh some stackoverflow answers also suggest to do actuator refresh Please have a look once and please let me know the reason.github.com/PradeepKumarHE/spring-cloufd-config-profjects

private String url; I have got a confusion. How could we get the value in client Project which is available at config Server Project.
Didn't get you client project means you are talking about any UI client?
@@Javatechie insurance-client project getting the url using (@Value("${insurance.provider.url}")
private String url; ) . How it got the url value. How this value made available to insurance client. This value would be available to insurance-config-server project only since git was configured in that project.
My actuator/default always show 404. If I check with health it is showing down. please help with this sir
Can you please check is any service is down ?
Also verify did you enable all endpoints in your application.properties or application.ymk
@@Javatechie I am only running this service.in the sts its showing application started. But when I check the actuator/default it is showing 404 and health is down.
in application.properties i have include all the endpoints(*)
Please checkout my microservice playlist config server example , I used latest spring boot version
Please follow the same , I believe it's issue with spring version
@@jayashrim4329 facing the same issue
@@sunilroshan8375 please check your branch in github. and try add your branch name in application.yml , It work for me. Please try it also
Sir when i change the url it need client app restart otherwise it is not woking
Did you annotated @RefreshScope
@@Javatechie yes sir @ResfeshScope over the class and also @Lazy on top of RestTemplate
Could you please confirm whether Enviroment variable will work at Config server application.properties or not?
Didn't get your question could you please repeat it with clarity
If we are using spring cloud config then spring will read properties from git right?
1. Here my question is whether we will get same git repository Properties file data in Enviroment variable or we will get our project application.properties data in Enviroment variable.? Or both?
2 .In your application you have used @value annotation, if we will use Enviroment it will work or not?
It should be in your application.properties
Why you need Environment.getProperties() spring is smart enough to load it from your application.yml file or properties file .
Please tag your issue 🙏
