Explore master transaction management with Spring Boot and Data JPA by implementing a real-world use case, covering rollbacks, isolation, and transactional concepts through hands-on practice.
Set up the Java development environment with the JDK, IntelliJ IDEA, and Maven, then create a Spring Boot project via Spring Initializer with Web, Data JPA, and Lombok dependencies.
Explore how a train ticket booking uses a transaction to combine passenger details and payment, and how Spring transaction management with Data JPA ensures atomicity through rollback on failure.
Create a passenger entity in a spring boot data jpa project, define fields like email, origin, destination, pickup time, and travel day, and map to passenger_info with json date handling.
Create a payment info entity with fields for payment details and map a passenger to multiple payments via a one-to-many relationship for transaction management in Spring Boot and Data JPA.
Develop and connect repository and DTO classes in Spring Boot, build booking request and response models, and handle booking status and total fare while integrating interceptors for data flow.
Develop the service layer to orchestrate booking requests by injecting repositories, persisting passenger and payment information, and coordinating booking flow in the database.
Create a simulated payment gateway and integrate it into the service layer. Model bank balances, validate payments, and throw an insufficient balance exception when funds are inadequate.
Implement basic transaction management in a Spring Boot app by wiring a booking controller and service, validating payment and passenger data, and demonstrating rollback on insufficient balance.
Explore core transaction concepts, including propagation strategies, isolation levels, and rollback with exceptions, and learn how transaction boundaries relate to public methods in SpringBoot and Data JPA.
In this course, you will learn about Transaction Management in general.
Why Transaction Management is important in any application.
We will start by setting up Java, Intellij, maven, postman and springboot from spring initializer.
We will first create entities with some fields then we will create the controller, repository layer along with the service.
Then we will go ahead and implement Transaction in our application.
You will learn to implement Transaction Management in your project
You will learn various strategies around Transaction rollback
You will learn about Transaction Isolation
You will learn about Transaction propagation.
will also create different entity classes and different data transfer objects, entity classes will help us save and retrieve the data in/from database.
Similarly the data transfer objects will help us take data from service layer and convert it to repository and vice versa.
We will also create repository layer to perform operations on database using spring data jpa.
We will also create a simulator which will act as payment gateway for us.
Then we will create controller class where will annotate with different annotations to expose REST API endpoints which we can test using Postman tool.
We will first test te application without Transaction management implemented, later on we will go ahead and implement transaction management and its different rollback strategies.
Finally we will test the application again through Postman to test our transactional and rollback scenarios.
At the end we will cover some important points that one must keep in mind while implementing transaction management using springboot.
