I personally like your tutorials. Could you also start a tutorial of any cloud (Aws/Azure/GCP) after micro service. It would be really helpful if you could do so.
this is why I'm, again and again, fall in love with java brains, Thank you java brains for enhancing my skills of 'spring profiles'. this is very helpful for me in development. I'm waiting for the actual microservice series.
I am an IT professional but your videos makes me travel back to my college days where I was blessed with some excellent professors. Thanks to you , the way you explain gives me opportunity to feel like I am in the same classroom and you are one of those excellent professors. I personally like your explanation because answer all WHY questions. We know WHAT to use where but you emphasise more on WHY should we use that.
Hey man, this was amazing. Before this video I was wondering how I was gonna set up profiles in maven! It's such a relief that this could be done via jar. Thank you very much!
Thank you. Your tutorials are just too good. In this particular context of spring profiles, I would like to add I needed to start my application with TWO profiles active... My React front end was facing CORS issue when accessing my spring boot backend - so had a special bean with a @Profile("corsSecurity") and to have TWO profiles (dev and prod) had this in my default application.properties spring.profiles.group.dev=dev,corsSecurity spring.profiles.group.prod=prod,corsSecurity and started my application with either java -jar --spring.profiles.active=dev or --spring.profiles.active=prod
Note - This method will work till spring boot 2.3. Starting from 2.4 there can be one single application.properties file separated by #--- for env specific values using spring.config.activate.on-profile= at the start followed by the env specific values
thumbs up for him to sell some merch. I've watch enough of your vids to justify buying some. Think of a nice pc sticker, or cooler sticker. JB-Vids!?!?
at 9:10 you said it overrides but i faced this issue, I did exactly what you did with previous project rather then creating new project with just web dependency, i was able to have two properties but new properties file was not overriding values written in default properties file, but moment i switched to yaml files overriding worked. can someone tell me why?
Hi @JavaBrains , if we define @Profile("dev") on class say ABC then only ABC class bean will be instantiated in whole application when ran in dev environment, is my understanding correct ? can you share your thoughts over this ?
what about unit tests? what profile will they use? how to control it? is it possible to have test profile that will not make it's way to the artifact and will be used only in the tests scope?
I'm enjoying these videos, I really like how they are structured around the desirable properties a configuration system should have. I have a question about the "default profile", though. Is it really correct to say that it's "always active"? My understanding is that, as soon as a different profile is explicitly set with "spring.profiles.active", beans in the default profile won't get loaded into the context. Even beans that are not "overridden" by the explicit profile. Also, is it correct to say (around 15:00) that setting @Profile("default") and not including any @Profile annotation in a bean are equivalent? I believe that no @Profile = "always present", while @Profile("default") = "present only when no explicit profile is given".
at 9:10 you said two properties files can be there in our project but when they are present at same location (src/main/resources) overriding is not working , different profile gets selected but values are not overridden, but two yaml files work how you told even in same location.
V Good explanation. One question , if everything remains in jar , and we have to say change some config value for prod , do we need to change the jar to include that new config value? As the production config sits in jar. We will have to build the code again to generate new build version. Isn't? M I missing something?
Hi Kaushik, thanks for the awesome tutorial, my question , is it possible to define profiles for external Property Files and configuration (properties) without using for example application.prop or Is it also possible to have profiles for external Property Files and configurations.
As always thank you for the great video. On a completely different topic, I am curious to know why you are using package view as opposed to the project files in IntelliJ project explorer. In my optional project view is more intuitive and exactly represents the actual folder structure. That's one of the reasons I switched to intelliJ.
I needed a bean for an integration test. I didn't use a profile annotation so it was instantiated via the default profile. I could see that in the log. However, I got no bean found when autowiring it into my integration test. How can that be when I could see that the bean had been created?
is it ok to have no default profile in the aplication and provide it manually for each environment with only the profile name in it? this could protect from running application with a wrong profile
You can, but remember that there’s always a default profile active. So, even if you have one configuration value in your app that’s common across all profiles, it would be silly to duplicate it across all your profiles. Hope that clarifies
12 step process architecture doesn't like it but selecting beans based upon external input, ie. config file, brings Spring back to inversion of control and code-reuse, which it seems to lose with annotations.
Question: Lets say you have a bean called Repository( in source code with active profile "production") in source code , in test (folder, for functional tests) having another Bean called Repository( to connect embedded H2 instead of actual DB) with active profile as "test" , when we run application will test bean will be injected to container? (It does not worked for me)
@@ayushgupta8239 - we are running test base class with with @activeprofile as test, qq: will spring context will consider Repository bean which is in src/test/jav?
i added this property on application-test.yml file spring.profiles.active: test Still it load the default profile. i am using the spring boot v2.2.4.RELEASE. is there any more change to do ?
@@bikramnarayankundu2924 Suppose i have three version of the profile. 1. Dev 2. QA 3.

Awesome tutorial! Thanks for putting this up! One confusion I still have is, you mention about having multiple configurations (as a result of multiple profiles) in one jar file at ruclips.net/video/P91tqdWUHE4/видео.html. But wouldn't it be ideal to separate out config from the jar files similar to ruclips.net/video/P91tqdWUHE4/видео.html because configs have a different lifecycle than the application itself. For instance, I do not need to release a new version of a jar for a config change.

I never want disappointed by the Explanation of Sir.
Thanks for your videos !!!
You are always the Best.
I searched half the web how it works..(and naming convention in profile!) Java Brains explains and I get it at once!
This is a very good explanation of what @Profile is. Thanks!
I watched this course in most rated paid online learning platform. That is no where near to your explnation. Koushik Your are The Man.
Amazing. Perfect mix between theory and practice. Thanks!
If this video is spring bean, it goes to @Profile("Awesome Explanation") ❤
Lol
Thankyou. Clear, informative and to the point. Spring profiles...done
Very helpful tutorial for learning profile in spring boot , I like the way that sir explain with real time examples in coding.
You are doing a fantastic job Sir
Really liked your tutorials. I was confused that how exactly the profiles are being choosed. You explain it quite nice👌
Nice explanation as always! Please start another series for deploying micro services

I needed to start my application with TWO profiles active...
My React front end was facing CORS issue when accessing my spring boot backend
- so had a special bean with a @Profile("corsSecurity")

spring.profiles.group.dev=dev,corsSecurity

and started my application with either
java -jar --spring.profiles.active=dev or --spring.profiles.active=prod

Nice Tutorial !! One question Can we set XSD of mainframe environment with specific properties with Spring Profiles?
Super excellent..
@Java Brains - Is there a way I can get in contact with you? I would very much appreciate that. Thank you.
useful skills, thank you
what about if we are creating War or EAR and deploying to Different Env, how I will choose profile there.

can we have beans configured for a specific profile but without corresponding specific property file?
Amazing ❤
What if you can't specify the profile in command line arguments because you have to deploy the .war in an environment such as Jboss? thanks

What happened if we have @profile("dev") & @profile("production") and we not activated dev or production profile than which bean should be initiated.

yes but you can override configs from environment variables.
so for minor change you dont have to release the app.
