So you don't usually need to care about that stuff and can just let the framework handle things. Spring provides so much magic and does so many things to get things going. There's a lot happening behind the scenes.With the help of Spring Boot, we get rid of ugly XML configurations on the Spring side of things and configuring your application is really easy. Almost "no configuration" is required.It has a mature ecosystem so you can readily find answers to most questions.It has nice in-memory database support, so that we don't need to create a real database and connect to it.And especially with the availability of libraries like Lombok, it has became a lot easier to focus on the business logic. Annotation-based development generates a lot of code for you behind the scenes.It is not usually the first option that comes to mind for smaller projects – but I will argue that it can be quite fast for prototyping.
The Spring framework is generally used for enterprise level/large scale jobs. I will briefly mention what they are and what they are good for and then we will see them in action. We will learn about a lot of useful technologies that will make you more efficient as a Spring Boot developer. We should check the capacity and only create new reservations if the current number of reservations does not exceed the capacity.Only logged-in users should be able to see the reservations page and create reservations.Users should be able to create new reservations by selecting the amenity type, date, and time.Users should be able to view their reservations.We will assume that the accounts of residents are pre-created and there will be no sign-up feature.We can think of our app as the reservation system for an apartment complex. We will build an amenity reservation system where users will log in and reserve a time to use a service such as fitness center, pool, or sauna.Įach amenity will have a certain capacity (number of people that can use the service at the same time) so that people can make use of the amenities safely during the Covid-19 pandemic. Fundamentals of Spring would be helpful.
Basic knowledge of relational databases (one-to-many, many-to-many, and so on).If you get stuck in any part of this tutorial or if I have forgotten to mention something, you can check out the GitHub repository I have included in the Conclusion.
In other words, we are not trying to build something perfect – but rather something that works. Think of it like building a project for a hackathon or a prototype for your startup in limited time. In this article I am going to walk you through building a prototype with Spring Boot.
