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

In our `todo` application, we used Spring Data JPA for database access and implemented JPA repositories such as `TodoRepository` and `TodoTypeRepository` to provide CRUD, pagination, and sorting capabilities on the `Todo` and `TodoType` entities, respectively. 

Let's look at the integration tests required to test the database access provided by the JPA repositories.

Let’s learn to test the database layer by using Spring Framework's @DataJpaTest annotation.
