Thanks a lot Kaushik. There are materials and tutorials everywhere but the depth and details of understanding the concepts that I get here are simply amazing.

December 2020: After Spring Boot 2.4.0/Spring Cloud 2020.0.0-M5 you need to include the dependency and create a bootstrap.yml with the spring application name, spring cloud config uri and the management endpoints web exposure include property there

Hey kaushik.... Because of you so many things are easy to learn.... Many many thanks to you make a wonderful video and make a easy to work in It industry.. 🙏🙏🙏🙏🙏

@9:54 I see "config.client.version". but the key "my.greeting" is not showing up. If I delete my spring-boot.config.yml and just use the default everything works. But If I have specific microservice config file.... things don't get udated. Anyone experiencing the same problem?

This is really convoluted. Thank god for good old JMX MBeans.

I think restart microservice is better choice. If we use accuator and @RefreshScope, it have 2 drawbacks: (1) accuator open some hookup API which might lead to security concern. (2) @RefreshScope impact performance a lot. All instances that use the config bean need to refresh ALL of its dependencies, not just the config bean.

Thanks Kousik it is really helping me simple and best.

The refresh scope is not working with microservice.yml file. It worked with application.yml

[pavanmodi]

Really it's very useful, spring cloud configuration, thanks to provide this kind of knowledge 🙏🙏

How would you refresh properties in a Microservice based environment? Like when there are X amount of servers running - and possible them being behind a LoadBalancer

[anshulsatish]

Hi Koushik, As you mentioned in the video could you please help us with the git tutorial which covers most of the use cases, especially reverting a merge request, solving merge conflict, and switching over branches without committing(branch specific or unmerged changes).

Great videos, what is the best practice to automate refresh without using rest calls?

[elangopadmanabhan]

Hi, I have a doubt on that @RefershScope. As you say, in our application perspective we are having n number of controller and we are using so many value from the property files. At that if we update the changes in cloud config server, we need to add the @RefershScope in each and every controller. If that is the case then, it will not be nice as we are going to add in 100's of controller if we are having it. Is there any other alternative, like if we want to use it for a entire application, configure it in a place and let all the get uploaded?

You are Awesome Bro You are A Hero You ROCK THE WORLD BRO YOU ARE SUPER AND THE BEST

[rossxie]

is there security control over who can call the refresh end point？

[StyleTrick]

Is there a good way to automate sending the POST request after making changes to the config server? Perhaps through Jenkins or something of that nature.

[chandrasekharreddyp]

question: in case i have multiple micro services instances for my service, then how do you call /refresh, because if we have 5 instances then though you call /refresh it calls only one instance.
any idea whats the solution for this use case??
