Learning Spring Boot 3.0 - Third Edition

Working with Data Reactively

In the previous chapter, we learned how to write a reactive web controller using Spring WebFlux. We loaded it with canned data and used a reactive templating engine, Thymeleaf, to create an HTML frontend. We also created a reactive API with pure JSON and then with hypermedia using Spring HATEOAS. However, we had to use canned data. That’s because we didn’t have a reactive data store on hand, an issue we will solve in this chapter.

In this chapter, we’ll be covering the following topics:

• Learning what it means to fetch data reactively
• Picking a reactive data store
• Creating a reactive data repository
• Trying out R2DBC
