Using Transactions

Transactions play a crucial role when working with databases to ensure data consistency and integrity. In Spring Data JPA, you can manage transactions using the Spring Framework’s transaction management capabilities.

In previous recipes, we implicitly used transactions, as some features require its usage; for instance, using @Modifiying annotation creates a transaction behind the scenes. In this recipe, we will learn more about transactions and how to use them in Spring Boot applications.

As an example of using transactions in Spring Boot applications, we will use them to manage the trading card operations between users. In a high-concurrency scenario, we want to ensure that users can exchange their cards with consistency and integrity.

Getting ready

For this recipe, we don’t need additional tools compared to previous recipes. As a starting point of this exercise, you can use a project that I prepared with the previous recipes in this chapter...
