Spring

Episode 87. Ok, it’s time to get Reactive!

It’s that Streaming-new-deal that has been taken over the web world, Reactive! You’ve heard about it, and maybe even tried to learn it a couple of times but find it confusing? Well, be confused no more since on this episode Bob and I explore the basic foundations of Reactive (and explain what is that makes is so confusing to begin with)

But that’s not all. We also dive on why is such a “hot” technology and why is the recommended approach on new microservices, even so, we also explore its drawbacks and why we shouldn’t rip everything apart to make “reactive” things.

Lastly we start exploring one of the “reactive” frameworks with Spring WebFlux, and explore how to “think” about Reactive (and came with the marble track analogy). In all, this episode will shed light on a topic that has been hard to understand, but on which, if done correctly can bring a very large performance gain!

Episode 83. Hey! Your app needs its yearly HealthCheck as well!

You got your new project, it’s a brand new service, and is ready to go! But… have you done a health check endpoint for your app? In this day and age of microservices with auto-remediation and auto-scaling, having a well-behaved, functioning health-check is very important since it dictates when to evict, scale up (or down) your service.

And the great news is, that for the “bigger” frameworks (like Spring or Microprofile) the work is almost done for us! With Spring Boot Actuator and Microprofile, we have tons of support and annotations, and built-in healthchecks for the main “things”, like database connectivity, Message Queue connectivity, even Email settings!.

So don’t put it off…start listening to this podcast, and then start creating that oh-so-needed health check for your app! Also, stay tuned to this episode as we give a “hint” of new podcast series to come!

Episode 82. Uh-oh Spring… you got some serious competition from Micronaut!

So the internet is all raging about this (not so little) framework that is doing it all. Created with a “cloud-first” mentality, @Micronautfw is aiming to be your next Spring Boot! And, oh gosh, how easy they are making it.

We dive into what makes Micronaut such a darling of the internet right now (not using reflection, GraalVM ready, better memory consumption) and see how much “stuff” is in there (the TLDR; A Lot). We go from creating a microservice, to looking at the different already-implemented features like circuit breakers, properties/profiles, beans, support for lambdas, micrometer, reactive programming, and all. While it might not have “everything” that Spring does, the reality is that it’s pretty solid.

Would you consider Micronaut for your next project? The answer is maybe (and for some cases, maybe Yes). So come, and take a listen to the underdog framework (Micronaut) that’s stepping up to definitively take the reigning Champ (Spring)

Episode 73. Spring Boot 2.0 is out! Hear all about it with Greg Turnquist

It’s new, it’s shiny, and is powerful! The new Spring Boot 2.0 framework is out! And we interviewed Spring’s own @gregturn to tell us what’s new, what’s improved and what has changed in 2.0. Diving into a bunch of topics including Reactive APIs, Bob, Greg and I set to explore Spring Boot 2.0 (and why you should upgrade). @gregturn is also the author of Learning Spring Boot 2.0, and he is an authority on many thing Spring.

This is an episode you don’t want to miss!

Episode 66. Ok, how about consuming Rest services

So we talked about how to create a rest service (using things like Apache CXF and Spring MVC), but sometimes, we actually need to consume these rest services. Luckily within the Java ecosystem there is a lot of way to skin that cat, and in today’s episode we at least cover 4 ways of doing so (including my favorite of the day, Feign). Come take a listen as we dive into Appache HttpComponents, Apache CXF with JaxRS, Spring RestTemplate and Netflix Feign on this fully-loaded episode.

Episode 64. Oh it’s time to re-boot Spring in Spring!

You heard about it, and you are probably using it already. It is the Spring framework that took over the Web (Spring Boot!). But what makes it so special? and what lurks under the covers? How did it became a thing and what is it really trying to accomplish? Come take a listen with our own Pivotal insider, Michael Minella! (@michaelminella)

Episode 53. It’s here, Spring EMMM…VEEEE…SEEE….(MVC!)

You always hear about it, Spring MVC this, Spring MVC that, wondering what really happens under the hood. Well, wonder no more! In this episode we break up and analyze Spring MVC to the core, so that you know exactly what happens! Taking it from the last episode (JavaEE), we push forward to how modern software development happens today!

Episode 51. Spring is in the air! What better than to talk about The Spring Framework and Spring Beans

If you stepped into the Java EE world, you must have run into Spring. There is Spring XD, Spring Batch, Spring everything-under-the-sun. Sometimes we keep using it as a rut, but today we take a look at Spring (and Spring Core) with a new set of eyes and learn the real reason for Spring Beans. A great introduction if you never been exposed to Spring, and a even better reminder of why Spring Beans exists in the first place!

Episode 44. Let’s show MicroServices some luv!

So it’s all the rage, and things have been getting smaller and slimmer (think your first cell phone), well, code is no different! Today we cover a trend on what is considered one of the better ways to scale, yet like everything else there are caveats. Bob is actually going to take us for a spin on creating our own MicroService by using Spring Boot!
