Building REST APIs with Spring Boot

In this live coding session, you will learn how to build REST APIs in Java with Spring Boot. You will learn how to bootstrap your application using Spring Initializr and the New Project Wizard in IntelliJ IDEA. You will learn some best practices to keep in mind when creating your APIs. By the end of this session, you will be able to create a basic CRUD REST API in Spring Boot.

OMG is Mala Gupta, she wrote the best JAVA certification book on market!

[kingstonmocktail]

Thank you for this, wish it was bit longer

[emrekaplan]

excellent video and straight forward !

[ZZZZZZZaaaart]

This is top, top knowledge. THANK YOU SO MUCH Dan was great. Thank you, thank you and thank you!!

[santhoshjke]

Very informative and well explained. Great session. Like you mentioned Dan I'm a big big fan of IntellIJ too and well worth to have the ultimate version.

[rmanamuli]

@Dan Vega thank you for sharing... @18:58...throw 19:00.. how did you generate the fields from the record class LiveStream ?

[WilmanArambillete]

excellent webinar! Very well explained! Kudos

[eddies.]

Great stream. A recommendation would be to maybe annotate sections in the video, so it's easier to navigate through topics when watching it as a video.

[adnansiddiqui]

@DanVega: At 19:00, how did the Model fields populate by doing a lookup on the word "live". You mention something about props. Can you please briefly explain. What IntelliJ plugin was used installed to do that lookup and pull all those fields? Thanks in advance.

[mwatkins]

not to be a doodooface but this sort of implies there is a previous video/project we are following off of here and its a bit confusing not coming from that, and not knowing which video this is a continuation of. I do appreciate the video though, youtube is plagued with a lot of bad java tutorials and this one is pretty good and easy to get up and running with.

you do go a bit fast with the code generations, and for instance someone has to know to import the correction junit packages for the assertion methods, so it might not be the best video to someone who is new to java itself.

I'm a newbie and I have no idea what just happened in this video

[mikojanchannel]

we are missing the part about connecting it to a *database*.
However many useful stuff said thru the video

[ahmede]

Thanks, Will there be other webinars for advanced REST APIs with Spring Boot?

[jmainex]

at 23:30, why was the assertNotNull(stream) and assertEquals("REST APIs with Spring Boot", stream.getTitle()) put inside the constructor and not outside of it?

[sofianezerrouki]

Thank you for this great information,
I want to ask you how to use services, and what's the difference between using repository instead of services on controller?

[saravana-kumar-m]

Great Session.

Where does the concept of "record" fit in the java world? What problem it is trying to solve? Can it be used as JPA entities? Can it be used as a replacement for DTOs. My DTOs have many fields that do not have a direct field in the entity but are computed on the fly based on a few other calculations. Can this be achieved using "record"?

Thanks.

[Mr_too_much]

This is the first time i had to comment something like this.

Why dont you explain a little bit more about things you are doing and how are you doing this? As complete newbie i have hard time to understand how did you create that record class, what is "target" for, why did you decide to generate hash and equal and i am still at the first half of the video.

Unfortunately did not help at all..

[traveho]

For the MutableLiveStream Class inside the model package, Can we use LomBok instead to reduce writing code?
Another question, Is using Service interface, Service Impl, DTO considered as a good idea?
