THat annotation @Load Balancing OMG... I was trying to solve an error of unknown host exception. After watching this video it was solved...

Field authorRepository in io.springbootproject.betterreadsdataloader.BetterReadsDataLoaderApplication required a bean of type 'com.author.AuthorRepository' that could not be found. The injection point has the following annotations: - @org.springframework.beans.factory.annotation.Autowired(required=true) Action: Consider defining a bean of type 'com.author.AuthorRepository' in your configuration.

Straight to point

Hi anyone can help me , how can we connect database by using eclipse ide with spring boot application and api

Thank you 🙂

Got this error after adding the @EnableHystrixDashboard and properties: Caused by: java.lang.IllegalStateException: Failed to introspect Class org.springframework.cloud.netflix.hystrix.dashboard.HystrixDashboardConfiguration

any one who is watching this video make sure you know run command is deleted for versions after 3.0.0 so you can skip this video as or use `mvn spring:boot run` command

Good course (thanks!), but it misses to explain two points which I think most would stumble on. 1) By using a Mono (and delayElement), you're freeing up one thread, but it's still another thread in the JVM that must "delay" (except it's handled by Spring webflux). Same for real I/O operations. There's no magic going on here, I think the video should make that clear. If you have slow blocking code (i.e., a long-lived DB call), you will have a thread blocked somewhere at some point. And if you have 10 of these, you'll have 10 blocked threads (or worse, less than 10 but with subsequent requests queued) -- just for a crude example. 2) Nowhere in this video series did it cover the critically important fact that actually, you get no threading by default unless you specify it somewhere; all rails would be on the same thread. You in your example Fluxes happen to be getting parallel threading, perhaps unknowingly, by using delayElement() (look at the source: return delayElements(delay, Schedulers.parallel())). Without that, everything would be executed sequentially on the same thread that you created the Flux. In reality, nobody will be using anything like the example Fluxes in production code. Crucial methods like runOn(), publishOn(), subscribeOn(), etc., should have been covered -- the whole concept and benefits of Reactor is lost otherwise, IMO. See: projectreactor.io/docs/core/release/reference/#schedulers

Great video as always 🔥

Love this.

I absolutely love this

This video is so amazing. This explanation is so simple to understand. The way this is broken down with a Java example is just superb. Thank you x 100

I was doing well until session #29 when adding the embedded Derby DB. I get this on startup. Any clues on how to fix it?

super content sir

Jwt bhi jaat h

Hi @Java brains can you give me free access to members only content

Way too many advertisements in the video.

Hi, would really help if you could do a video on arrays, list, and arraylists private List<Topic> topics = new ArrayList<>(Arrays.asList( new Topic("Spring", "Spring Framework", "Spring Framework Description"), new Topic("Spring1", "Spring Framework1", "Spring1 Framework Description"), new Topic("Spring2", "Spring Framework2", "Spring2 Framework Description"), new Topic("Spring3", "Spring Framework3", "Spring3 Framework Description"))); The above is quite confusing for me. Appreciate your guidance. Tq

Thanks, this is the clearest from scratch video i found so far..so difficult to explain yet you made it look easy

fresh video

C

No AQL Exception solved with adding @Component in the Entity class

Constructor injection not just helped in removing @Autowired but also gave the ability to make the repo variable final.

Awesome explanation

Thank you! I am getting ready for Level 2 course =)

Funny you should mention Kissinger. It took a seasoned Indian diplomat to remind him of his heritage of being progeny of Jew refugees from WW2 and who was now turning a blind eye to the genocide in Bangladesh. You should look it up on the internet; he apparently pulled the table cloth from the breakfast table yelling he ain't a refugee. But the points you've mentioned are really good face savers when staring at an unknown problem. Good content, as usual.

love the way you explain by giving some random dialogs like "Hey Spring Security, I want you to blablabla"

This problem reminds me of a game i used to play when i was young with 3 and 7 with a group of friends. We were counting one by one and every time when someone missed the BUZZ ( in our country we would call it BOLTZ instead of BUZZ :D ) had to drink the BOOZE. Nice job anyway

Shopify sent me here :rofl:

But how many good Interviwers are there, most of them are trying to show you that you don't know this

Is using Method References a good practice for maintainable code? I see that the reader has to actually look into the parameters of the and keep both of them side by side.

Best explanation

Good one ❤❤

Besides providing sharp intelligent know-how, these latest videos have a totally fresh wit. Thanks, Java Brains.

We can also use Java Streams for this Step2 : personList.forEach(person -> System.out.println("lambda person : " + person)); Step 3 : personList.stream(). filter(person -> { return (person.getLastName().charAt(0) == 'C'); }).forEach(person -> System.out.println("stream person : " + person));

Hi Kaushik Are you planing vedioes on ai in java

In the world of paid courses, you're the savior.

Great video

Awesome! I was asked this in an interview.

the last two sentences are brilliant :)

Thanks a ton.

Thank u for your video )

Nice and informative, thank you so much....🙏

hey Koushik, thanks for this content. I really appreciate the efforts you are taking for video aesthetics as well. Hence a small suggestion as your fan, if one of your background walls, if not both, are painted in a darker tone, say a dark blue or so, your video will look a even better. ❤

Thanks for this 😁😁

Please make a series on Java 21 features.
