In this advanced-level course, you’ll learn to create REST APIs using the Spring Framework. The course gives a detailed experience in designing, implementing, and documenting REST APIs with end-to-end features like database integration and monitoring.

Firstly, you'll set up a Spring Boot project and create fully-functional REST APIs to manage your to-do lists. Secondly, you’ll learn database integration using Spring Data JPA and consume APIs using various tools such as cURL, Postman, and the Swagger UI. Thirdly, you'll learn Aspect-Oriented Programming (AOP) in Spring and Unit test the APIs using Spring Framework. Lastly, you’ll learn to document APIs using Springfox and Spring REST Docs and monitor them using the Spring Boot Actuator. 

By the end of this course, you'll be confident to design, implement, and document REST APIs end-to-end using the Spring Framework, including advanced topics like AOP, Unit Testing, and Monitoring.

REST APIs with Spring, JPA, and Springfox

A **JPA entity** is basically a POJO representing a table in the database.

Similarly, the object of an entity class corresponds to a row in the database table.

Let’s learn a few handy annotations to transform a POJO into an entity.

The most common annotations are `@Entity` and `@Id`:

* The `@Entity` annotation allows mapping a POJO to a database table by the underlying data access layer.

* The `@Id` annotation allows mapping property to a primary key in the database table.

Let's use these annotations to convert `TodoType` POJO to an entity and map it to the `todo_type` table:

Let’s learn how to set up entities by using Spring Data JPA and automatic database schema update.
