how to connect spring boot with mysql database
To connect a Spring Boot application to a MySQL database, you can follow these steps:
Install the MySQL database server and create a new database for your application.
Add the MySQL connector library to your project. You can do this by adding mysql-connector-java dependency to your pom.xml file if you are using Maven:
Alternatively, you can download the MySQL connector library and add it to your project manually.
Open the application.properties file in the src/main/resources directory of your project and add the following properties:
Copy code
spring.datasource.url=jdbc:mysql://localhost:3306/database_name
spring.datasource.username=username
spring.datasource.password=password
spring.jpa.database-platform=org.hibernate.dialect.MySQL8Dialect
Replace database_name, username, and password with the name of your database, the username you want to use to connect to the database, and the password for that user.
Add the @Entity annotation to the entity classes in your project to indicate that they represent database tables.
Add the @Repository annotation to the repository classes in your project to indicate that they are used to manage data in the database.
Run your Spring Boot application. It should now be connected to the MySQL database and you should be able to perform database operations using the entity and repository classes in your project.
Overall, connecting a Spring Boot application to a MySQL database involves adding the MySQL connector library to your project, configuring the database connection properties in the application.properties file, and annotating the entity and repository classes in your project. This allows you to use the features of the Spring Data JPA framework to easily manage data in the MySQL database.
In this tutorial I showed how to connect to MySQL database to spring boot application.
The instruction starts from creating a fresh new database to downloading spring framework from spring initializer and connecting to database.
I used Heidi sql to create the database and IntelliJ as the Java IDE. As an example, I used the idea of developing an application which will offer the history of music.
