![]() If no name is specified, the default is to use the name of the field. The annotation is used to specify the name of the column in the database table that corresponds to the name and email fields. In this case, the GenerationType.AUTO strategy is used, which means the database will choose the appropriate strategy based on the database being used. The annotation is used to specify that the value of the primary key should be generated automatically by the database system. The Id annotation is used to specify that the id field is the primary key of the entity. In this case, it is mapped to a table named "users". The annotation is used to specify the name of the database table to which this entity is mapped. The annotation is used to mark this class as a JPA entity, which means it can be persisted to a database table. This is a Java class that represents a User entity and is used in conjunction with a database using Jakarta Persistence (previously known as Java Persistence API or JPA) for object-relational mapping (ORM). To do that, create a file called "docker-compose.yml" at the root level, and populate it like that:Įnter fullscreen mode Exit fullscreen mode In this case we will run the DB not by installing it but by using a Docker container ![]() This is not wrong, because we want to connect this app to a Postgres DB, but we don't have the DB Running. If we simply run the application (if you have the extensions installed you should have a play button at the top-right when you have the JavaApplication.java file open) like this, it FAILS In my case, the path is c:/workspace but feel free to choose any path.Īfter generating it, you should see this popup at the bottom right (or you can simply open the folder with any IDE).Ĭlick "Open", and you should have something like this: Now you should decide a folder to generate this project into. Spring Data JPA (To handle the database)Īnd finally Selected 3 dependencies, press to continue:.packaging type: Jar (you can choose war if you want).Artifact Id: live (you can replace it with what you want and change the upcoming part accordingly).Spring Boot version 3.0.4 (any 3.0.0 + should work).Maven project (you can choose Gradle if you want).We will create this application by selecting, in order: Then you should select how to build your Java project. If you have these extensions, you should see a similar prompt when you open VS Code. If you use VSCode, I'd recommend to install these 2 extensions: ☕ Create a new Java Spring Boot application (Optional): Postman and Tableplus to follow along, but any testing tool will work.Maven (or any other build tool for Java). ![]() We will go with a step-by-step guide, so you can follow along.
