such an awesome explanation, thanks a lot sir.

[@harshsinha6067]

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

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?

[@Javatechie]

1. Yes we can 2. Didn't get you properly

How to differentiate between multiple property files for different environments?

[@codingispassion6376]

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

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 ?

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?

[@Javatechie]

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

[@pratappadhy2005]

Eureka is service discovery and Spring Cloud Config globally managing the configuration for multiple micro service with externalization, consistency and real time.

[@bkit5]

@@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?

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.
