I am not someone who writes a comment regularly or likes a video. But I have to say about this video: well job done!

[@ProgrammingTechie]

Thank you

[@huseyinturkmen06]

Very usefull video but i think u forgot a little point that can make confused a programmer who hasn't experience so much about spring. The point is that you had created a db named "order-service" in mysql before running the order service but if i havn't missed you didn't show it in the video but you showed the right way of it while running the inventory-service. Summary: You should have created the database in mysql management interface with the same name in application.properties before running the API or you will be having an annoying error which isn't easy to solve without knowing this ))

Instead of making ddl-auto to create-drop you can simply put condition in bean for Inventory service to check if table already has data using findAll() and if it's null only then insert data into table. That way you don't have to make any changes to properties file.

Just a hint: you don't need to create new package and then new class inside it. You can name your class packagename.Classname and the package will be create automatically. Quicker

[@SampathkumarP]

Fantastic video. Really appreciated. for the work

[@tarunsoni6971]

Great tutorial, One thing which I noticed right after 1hr in the video that when you were creating repository and service references in the Service and Controller classes you wrote it like you were going to use the @Autowired annotation there but instead you went with a constructor injection which means reference will be initialized at construction time but then didn't use the annotation which left me wondering that now spring won't be managing that object neither creating and nor destroying and won't inject and inside that constructor which will be created by lombok will have a new key word in it to initialize the object?

[@samirpanchal5883]

Those who are facing problem recognizing inventory or order service module in intellij try following steps: go to File->project structure->click on modules tab on the left side-->click on the plus icon-->click Import Module --> and select module from the popup and hit OK. If your submodule is not visible then make sure you extracted in the right folder or reload project from disk. Hit like if it solve your problem so others can see it. I wasted 1 hour on this issue AND thanks for this course.

thanks sir this is the great one..

[@turgaycabalak9712]

Thank you so much for the lecture. Btw I used the docker image for mongo and used the properties like below: spring: application: name: product-service data: mongodb: auto-index-creation: 'true' authentication-database: admin database: product-service username: root password: root port: '27017' host: localhost instead of defining uri. That's why I'm little confused especially in the integration test(because you are using uri there but i don't have). Still it is going well please keep going. Appreciated...

[@IvanRandomDude]

You can use both ways, just make sure you don't MIX them lol

[@kennedydre8074]

Also, is there some way to run validation on the request object in the API layer (I would like to fail early)? Something like Joi but for Java? This is also to ensure that all required fields are passed.

[@ascar66]

thank you, nice video

[@codegeek8256]

Hi @Programming Techie i hope you are well. Thanks for this part 2 series, I can already see it is going to be exciting. Please introduce docker and kubernetes so that we can at a go orchestrate the services as they grow. And Please use Kafka this time around. I wish we could also add a UI service. Thanks very much. Your work is helpful and Impactful, Looking forward to what is coming.

[@ProgrammingTechie]

Hi, there is no plan to add UI also this time, but I am going to use docker and Kubernetes in this tutorial.

[@antonvovk8867]

Thanks for this wonderful content! Could you please advice why Ide does not allow me to Autowire Mock MVC and ObjectMapper in my ProductService tests? Autoriwing works fine for Product repository but not for the above ( Test cannot not run because of this I assume.

[@sebastiansilvavidal452]

hi, in the minute 14:00 when you add the anotation "RequiredArgsConstructor" to the ProductService class; is that the same as putting @Autowired on top of "private ProductRepository productRepository" ? (without the modifier 'final'), or is there any difference? thanks for your videos.

[@khoa-hd]

When you add @RequredArgsConstructor above the class and declare private final ProductRepository productRepository, that means you are using Constructor injection.

[@melihcankilic5918]

thank you bro, it is very good.

[@user-uw8eq1xw3h]

Hi Sir , Firstly Thank you for your great work !! As a Beginner It is helping alot !! Can you also please share the Database scripts for creating the Table structure as well . So that it would be easy to execute and run the application . Like Order service , Inventory service scripts.

[@rockdynamics7766]

This videos is so helpful to me .Pls where is the kubernetes deployments tutorial ?

[@rajatverma1688]

I have just started the series, definitely enjoying your content. Thank you. Quick question: At 43:13, I was expecting that the size of the products should be 2 because you already created an object before. Do the mock post request to create object does not actually creates the product, or did you deleted it previously?

[@Mallikarjundev-mh6ge]

Test containers are using db from the docker image which is online. But other services are using Mongodb from the system(computer). That’s why used 1 as it was empty from the beginning.

[@miajia5151]

谢谢！

[@SergioGonzalez-pq3gc]

Hi! Great video, I just wanted to know if you could shed some light into this warning of vulnerability within the dependencies of springframework that are highlighted by the IDE saying: vulnerability info for maven:ch.qos.logback:logback-classic:1.4.11. Is it something we should be concerned about? Is it exploitable? Thank you.

[@catty1020]

Great video with in depth explanation of concepts. If anyone can help me it would be great, I am actually facing an issue where on compiling the project the tomcat port and connection is not showing up the messages like it did in the video at 22:09 minute. I have downloaded the plugins, and tested the connection.

1:28:48 I recently downloaded my projects from Spring Initializers. While it gave me spring-boot-maven-plugin .. there was no compiler plugin in the code generated by initializr. So as it wasn't there in single module projects, i'm not adding it in multi module project's root pom.

A small Question from my understanding so far the Database in the ProductService will be mainly used just for storing Data right? Why do we use MongoDB here since normally SQL Databases are considered better for storing data right? Or did i misunderstand something here?
