Build Efficient Persistence Layers with Spring
Spring Data JPA is incredibly popular because it's so easy to use. It utilizes established JPA implementations, like Hibernate or EclipseLink, to provide an efficient and rock-solid object-relational mapping. On top of that, Spring Data JPA adds a layer that encapsulates almost all the complexity and boilerplate code required by JPA.
You usually only need to extend one of Spring Data JPA's repository interfaces to get a fully functional repository that handles the standard CRUD operations for one of your entities. In the next step, you can add query methods to your repository definition, and Spring Data JPA provides you with the required query and all the boilerplate code required to execute it.
All of this enables you to focus on your business code and improves your developer productivity. But it also comes with a price.
The complexity is still there; you just don't see it!
Spring Data JPA's abstractions make it seem easy to implement your persistence layer because you no longer see the complexity. This is great if you know how JPA and Spring Data JPA work. But it makes learning all of this much harder than most developers expect.
Using Spring Data JPA, you not only need to know how to use its APIs, but you also need to understand the complexity it's handling for you. Otherwise, you will always wonder if your code produces the expected results, and you will often get surprised by unexpected SQL statements and other inefficiencies.
Learning Spring Data JPA in a structured way makes the difference.
I experienced this first hand when I started to learn Spring Data JPA myself. I had been using JPA for a few years and expected that switching to Spring Data JPA would be easy. Unfortunately, I didn't have the time and materials for learning Spring Data JPA in a structured way.
I made the same mistake that I see so many other developers make: I thought I could learn everything I need by using Spring Data JPA in my project.
Well, it somehow worked in the end, but I could have saved myself a lot of frustration and lots of overtime. I could have easily avoided most of the problems if I had a deeper understanding of the framework. But that's hard to get if the important parts are not directly visible.
In my consulting and coaching projects, I see a lot of developers go through the same struggles. They do their best to learn what they need and to understand how Spring Data JPA works. But how shall somebody ask questions about something they don't even know exists?
That quickly changes when someone guides you along the way and points out the important but sometimes invisible details. That's what I'm doing in this course. You should already know JPA's basic concepts, and we will then add Spring Data JPA on top of it. We will dive deep into all of its usability features and the extra functionality it provides.
Create reliable and scalable persistence layers
Having completed this course, you will be well prepared to design and implement robust and scalable persistence layers using Spring Data JPA.
Instead of hoping that Spring Data JPA magically performs the right operation, you will know which APIs you have to use. You will understand how Spring Data JPA works internally, which operations it performs, and the boilerplate code it provides for you. You will be able to confidently use its features to build maintainable and efficient persistence layers.
Your new skills will not only improve the way you write software. They will also establish you as a true expert within your team. With your expertise in the most popular persistence technology in the Java world, you will be well-prepared to take on new, interesting tasks and grow your technical career.
