Transactions in Spring

This training covers the way the Spring Framework lets you control transactions in your application, offering many practical advice directly applicable to real-world projects. The topics covered go beyond just understanding how to use @Transactional, diving into the internals of Spring implementation, Hibernate integration and performance concerns.

During this intense 3.5 hours video course we'll walk through a series of increasingly complex exercises that demonstrate the features that we study. If any concept remains unclear after watching the video, your are invited to ask any questions.

Agenda

• DB Transaction - ACID attributes
• Transaction propagation - practical tips
• When is a transaction rollbacked
• @Transactional internals - proxies, thread locals, pitfalls, programmatic alternative
• Nested transactions - best practices and pitfalls
• Performance - monitoring and tuning transaction size
• Hibernate/JPA Integration: read-write cache, auto-flushing, lazy-loading, streaming queries

What to expect?

The course if extremely hands-on, composed of a series of live-coding exercises through which we will explore and demonstrate the topics we discuss. Then, any tricky concept we encounter is explained via a series of fine-tuned slides.

After purchase you'll get access to the video recording, slides and zipped code so that you can repeat all the work on your local machine too.

This Training is for you because:

• You are working with Spring and you are persisting data in a Relational Database
• You are new to Hibernate and you want to understand an essential part of the Entity Manager runtime behavior
• You want to know more about the internals of @Transactional

Prerequisites:

• Working knowledge of the Java language.
• Prior practical experience with a relational database is recommended.
• Prior contact with Hibernate is nice to have.

Technical Requirements

To solve the exercises yourself, you will need a Java 8+ SDK installed (latest Oracle JDK will do), a decent IDE (preferably IntelliJ Community or Ultimate), and access to GitHub and Maven Central.
