JPA for Beginners

These courses are included in the Persistence Hub:

JPA for Beginners
If you are new to JPA / Hibernate / Spring Data JPA, this course is for you. You will learn all basic concepts, mapping annotations, and query features. After completing this course, you will be able to create simple persistence layers yourself and help your team to work on more complex projects.

Advanced Hibernate
If you want to learn about JPA’s and Hibernate’s more advanced and complex mapping and query features, this course is for you.
You will learn how to use embeddables, composite primary keys, custom data types, inheritance mapping strategies, lifecycle callbacks, and common patterns to model your persistence layer. I will also show you how to use Hibernate’s multi-tenancy feature, the Criteria API, and some of Hibernate’s proprietary APIs to implement complex business requirements. To get the most out of this course, you should be familiar with the basic concepts, mappings, and query features.

Hibernate Performance Tuning
This course is for you if you want to improve the performance of your persistence layer. I will show you how to monitor Hibernate during development so that you can find performance problems as early as possible. You will learn how to use the best projection for each use case, avoid inefficient mappings, fetch associations as efficiently as possible, use Hibernate’s caches, and much more.
To get the most out of this course, you should be familiar with Hibernate’s basic concepts, mappings, and query features. You should also have built a few persistence layers with Hibernate and deployed them to production.

Spring Data JPA
This course is for you if you’re using Spring Data JPA to implement your persistence layer.
You will learn to configure Spring Data JPA, use its standard repositories, and test your persistence layer. I will also show you how to avoid performance problems, extend Spring’s repositories with and without implementing your own methods, and give you an introduction to several integrations of other frameworks to provide auditing, create more complex queries, migrate your database, and much more.
To get the most out of this course, you should at least be familiar with JPA’s basic concepts, mappings, and query features.

Data and Communication Patterns for Microservices
This course is for you if you want to design a microservice architecture for your application and wonder how these services will communicate. Unfortunately, that’s not as easy as some conference speakers want to make you believe.
I will explain why most of the concepts used in a monolith no longer work in a microservice architecture. You will learn patterns to avoid distributed read operations, or if that’s not possible, to at least make them as resilient as possible. I will also show you how to design distributed write operations that ensure data consistency without requiring any locks or causing other scalability issues.
To get the most out of this course, you should have a basic understanding of Spring Boot and some experience in system design.

Patterns for Persistence Layers
This course is for you if you’re looking for patterns to structure and implement your application or if you want to get a better understanding of the patterns used by your persistence framework.
You will learn about commonly used patterns with their strengths and weaknesses. I also explain the available alternatives and how to decide which one to use in your application.
To get the most out of this course, you should have some experience in application and system design.
