What you'll learn:
- You will learn to create REST API and interact with Database
- 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 to create layered architecture based application
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.
