Spring Boot + MariaDB Integration

Spring Boot is a Java-based framework used to build web applications and microservices. It is built on top of the Spring Framework and makes it easy to create stand-alone, production-grade Spring-based applications.

MariaDB is a fork of MySQL and is a popular open-source relational database management system. It is known for its high performance, reliability, and ease of use.

Spring Boot can be configured to use MariaDB as its database. This can be done by including the MariaDB connector and other dependencies in the application’s classpath and then configuring the application’s properties to connect to the MariaDB instance. Spring Boot also provides a set of annotations and classes that can be used to interact with the MariaDB database, such as @Entity and JpaRepository.

Here’s an example of a simple Spring Boot application that uses MariaDB as its database:

1. First, you’ll need to add the MariaDB connector and Spring Data JPA dependencies to your project’s pom.xml file:

<dependency>
    <groupId>org.mariadb.jdbc</groupId>
    <artifactId>mariadb-java-client</artifactId>
    <version>2.7.0</version>
</dependency>

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>

2. Create a new class called MariaDBConfig that will be used to configure the connection to the MariaDB database. In this class, you'll need to set the database connection details and create an instance of the DataSource class:

@Configuration
public class MariaDBConfig {
    @Bean
    public DataSource dataSource() {
        MariaDBConnectionPoolDataSource dataSource = new MariaDBConnectionPoolDataSource();
        dataSource.setUser("your_username");
        dataSource.setPassword("your_password");
        dataSource.setUrl("jdbc:mariadb://host:port/database");
        return dataSource;
    }
}

3. Create a new class called Person that will be used to represent the data in the person table in the MariaDB database. This class should have the @Entity annotation and the necessary fields and getter/setter methods:

@Entity
public class Person {
    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    private String name;

    private int age;

    // getters and setters
}

4. Create a new interface called PersonRepository that extends JpaRepository. This interface will be used to interact with the person table in the MariaDB database:

public interface PersonRepository extends JpaRepository<Person, Long> {
    // custom methods
}

5. Finally, in your main class, you can use the PersonRepository interface to perform CRUD operations on the person table in the MariaDB database:

@Autowired
private PersonRepository personRepository;

public void savePerson(Person person) {
    personRepository.save(person);
}

This is just a basic example, and your actual application will likely have more complexity and additional features. But this should give you an idea of how to set up a Spring Boot application to use MariaDB as its database.
