Can you make a video on propertly error handling?

You've mentioned at the testing part, that we should not use a different database from the production one (eg.: postgres / h2), I would really be interested in seeing a video about these types of best practices, thanks😁

Thank you very much for this detailed Spring/Spring Boot, "How Not Tos". It's great to see a teacher who consistently and effectively communicate best practices.

For the @Autowired annotation, you should use it if you have more than one constructor otherwise Spring will fail to inject the dependencies, it is a kind of a hint to tell spring which constructor to use. Nice video and very good explanation, keep going 💪🏻

Thank you for this video. I'm a trainee and you videos are very helpful. Waiting for lesson about proper testing of a Spring Boot application.

I would really like a video about testing the databese and querys!

Thanks for this! I would really indeed like a video for the case against using H2 for testing. We use Oracle in production (migrating to postgres enterprise in a year or so) and would like to hear what you would suggest here. Thanks again!! :)

wow it's 2024 and you're still the best spring youtuber in the whole world

Great video, thanks a lot! We'll love to see a video where you explain how to test with the same DB and not use H2.

Thank you very much for the explanation. Would love to see why we should not use H2 for testing video! :)

Great content...your points are ones that I do see fairly often. Keep the vids coming 😀

A small glance of how beautiful code can be, thanks for sharing

It would be nice to record one video only about testing in spring-boot, I am currently struggling with testing in spring-boot.

To Error handling, since Spring 6 you can use "Problem Details" like standard and not have your own ErrorDto

Thank you, I did not know about records. Seems like a pretty essential, powerful, and very simple to use feature. If I might suggest a topic for a future tutorial that has NOT been covered properly by anybody: Spring Boot 3 + Spring Security 6 + Tomcat 10 (deploy webapp as WAR) + Azure AD authentication & authorization using Microsoft's spring-cloud-azure-starter-active-directory Maven dependency. For extra points or as part of another tutorial... how to handle libraries (like the microsoft dependency above) that use logback when you are deploying to a Tomcat 10 that is configured for log4j2 logging (throws a logback exception when it tries to cast LogbackServletContainerInitializer to jakarta ServletContainerInitializer). Both of the tutorial topics I mention are fairly common configurations that nobody seems to be covering.

Awesome content. I'm new to Spring Boot and this was very informative. I didn't know about Java records at all.

Thank you nelson, please continue this form of videos

Thanks for your content. Please, make video tutorials on testing in Spring Boot, especially integration testing, test containers.

Great content as always. Could you please make more in-depth testing videos

I've been looking up on how to make the switch from H2 database to tests containers. I would really appreciated a video on it, thank you!

I learned a lot. Thank you

I have learnt something new. Thank you very much Nelson

Please make other testing video like what you said in this video. Very grateful for this Thanks in advance! Lovely videos like always

Hi Nelson, please make a series on testing Spring Boot applications.

Thank you brother, very usefull info

Great video @amigoscode Thanks a lot for sharing your knowledge!

Hi, you are my fav youtuber, you explain clearly and i understand almost everything. I wait from you the best tutorial about functional programming, lamda, streams and etc from zero to hero with simple explanation

@Valid was correct...@Validated is for partial or group based validation...

Great video as always! Can you please make a video on why not to use h2 for testing? Thanks 🙏

👍👍👍👍Thanks for the video tutorial

Thanks you Buddy!

I see that you have here at 12:00 FakeS3 class, so it means you modify your production code to be able to test it. Why you do not use in this case localstack, it is also a standard defacto like testcontainers for testing. Correct me if I am wrong and this is just for Demo purpose

Excellent! to the point!

Thank you very much good luck

Setter injection is allowed when more then 7 dependencies required in the given class to avoid the "Method should not have more then X parameters" Sonar issue (if you use any static code analysis tools).

Salamu alaykum brother, could you do a video on @Async and CompletableFuture?

thanks a lot !

Very good video! Yes please go ahead and do a video on testing!! Another mistake: not using lombok!!!

great video! well explained, thanks can you please show how to manage authentication with jwt, redirecting after success login and managing roles?

this is goldmine!

So cool, very nice tips, thank you buddy

Hi Nelson! :) Great video, I would love to see a video about database testing with an practical example

Amazing content man, I'll watch every video you have. Amazing, simply amazing!!! 🤩

Happy to learn, I thought Field injection was the that makes it hard to unit test, and Setter and Constructor injection were fine 👏🏾

this video gives me enlightenment, جَزَاكَ ٱللَّٰهُ

nice video thanks!!!...why your courses are not available at Udemy??...please start your channel there as well!!

Thanks a lot. I learned a lot. Please let me know, how i can learn better testing within spring boot, e.g. use right and necessary parts of apllication context

Salam alikom akhy(Brother) good job, keep do it. Ramadan moubarak👉

Hi @Amigoscode, your'e an amazing teacher and mentor, we want to buy your full stack course and learn from you, however the price is too high for people in India, as we have to pay in USD...

Salam alykun Nelson. Please make a video on why we should not use H2 for testing. Thank you.

I understand for most instances constructor injection is better than setter injection but what do you mean by you can't mock the dependencies with setter injection. Surely you can just Create the object and then create a mock of the dependency and pass that dependency in through the setter.

thanks

What's the theme called. How to apply it. Looks dope

Great content. Keep going

Your video is very clear. Whats your setup?

Can you give more insights about that logger part? What to log, what not to log, best way to use log, and when to use info, debug, warn and error

Could you release a full course of Spring boot testing please ?

Thanks sir for making useful videos for us. But I request you very respectfully to work in a project in spring boot having at least 6 entities/tables using spring boot in the back end and React/Angular/Next in the front end

Essalamu Aleytkum Nelson, I love the way that your IDE looks. Would you make a video of what plugins do you use?

Please record a video on testing 👏🏾🙏🏾

please make tutorials about XLD , Jenkins and déploiement of an application , it's important and you can make it simple

Would you suggest to use Lombok annotations for getter and setters? Or it is better to do it without lombok?

could you please create a detailed video on error handling?

Highly recommend his full stack course

Though xml is verbose it does separation of concerns better. The framework is less invasive as all you have is pojos.

Hey, brother! If it's alright with you, could you possibly make a dedicated video that covers the topic of testing in Spring Boot? It has the potential to greatly benefit your audience.

nice video ❤❤ thanks

Tests, I'm not doing that enough. We write lots of code at work, and I believe we should also be writing tests along side. But our output rate doesn’t allow it. Can we start writing tests now? It looks like a daunting task

The main reason to use dependency injection is NOT "to have Spring do things for you" or "so that you can use singletons". It is used to do dependency INVERSION. Also, leaving the @Autowired on constructors is not a mistake, it servers a role as documentation.

Can't wait to see what mistakes I'm already making! 😊

Great video. Can I request for another video for possible solution in one of those mistakes? Thank you.

Could you please make video about domain driven design (ddd) design pattern with spring boot?

One of the best videos on the channel! Congratulations again, you are an inspiration!

what extensions do you use in the intellij?

Please make a video on testing Spring Boot Application using Data Sources

Assalam mu alaikum brother, Can you please make video on Muslim Software Engineer Routine in Ramadan… eagerly wait for it😊. And yes love from India🫶🏻

Hello Nelson! I really would like to see how you test with real database, because recently I saw your video with a h2 in junit testing.

Hi, If I am using java 1.8 where the records are not present, which would be the best approach? create a mapper also? or should we use JPA Projections always instead? Could you please make a video about it? thanks

Your points are valid, but I don't think record really matters in terms of exposing internal data..you are on the right path, mapping your entity to dto like that is pretty crude..of course in the real world tools like mapstruct or dozer are used to seamlessly map to DTOs.

salam alaikum brother thanks for everything. you are the best. hi from türkiye

Whats the theme that you are using? it looks nice

Salam, can make a video of what is the difference between using lombok @Data annotation and the record classes and which is better? I couldn't find a good compression and really carious about it

Please please please do a video on testing database without H2. I'm struggling in my work with this 😢

could you explain why we shoulnt use xml? do u recommend using gradle?

what is the particular IDE you are using in this video?

Yeah i gotta take some time to learn more about Records. They seem simple yet powerful. Anyone seeing the benefits of them, and mind further explaining their uses?

It's constructor vs setter injection, btw.

if you pls record video how to avoid H2 in testing, should be amazing

hi Nelson, good tricks thank you. which plugins do you use on IntelliJ ?

Good advices for beginners but most of them are not spring boot related. Using DTOs/Records to decouple the database schema from the frontend side or not calling directly the repository in the controller are best practice in every languages

what's the difference between @SpringBootTest and @DataJPATest and why should I only use the former once?

2. Using records, could have some extra explanation as what it does underwater, basically I use a record with the same variabele name and it looks up a record with that variable name? and returns me a single entity with that name? or multiple within that record? 3. Dependancy @Autowired vs constructor injection, the constructor injection is very good for testing the classes as it can be mocked using mockito. @Autowired is deprecated by spring boot. Good that you give one line for testing, as for testing the dependent classes can be mocked. For the testing is there a sample I can look into ? So I can speed up my own code as well? :)

Is this IDEA or what IDE u use in this video?

How is the fasting going? hope its good. Please do a complete tutorial video on testing

Spring Boot provides validation dependency which i more better way to do the validation of request object. Also, I would like to know how do you map the data from request to entity and from entity to response?

@Amigoscode Another mistake what I have seen is not using springdoc to generate OpenAPI documentation. This is a lifesaver to deliver to QA instead of using Microsoft Word.

Que IDE estás utilizando?

How do you run controllers with IntelliJ ?

14:20 what is diffrence between jakarta validation and spring ones?

what about field injection with the annotation @Autowired? is this a good practice or should be avoided? if yes, why?
