MySql is one of the most widely used open-source relational databases, and Spring Boot is a popular framework used to build Java applications quickly and easily. Integrating MySql with Spring Boot can provide high-performance applications with minimal effort.
In this step-by-step guide, we will show you how to connect MySql with Spring Boot. We will cover the following topics:
- Setting up a MySql database
- Adding MySql dependencies to your Spring Boot project
- Configuring MySql connection details in Spring Boot
- Creating a MySql repository
- Testing the MySql connection
So, let’s get started!
1. Setting up a MySql database
Before integrating MySql with Spring Boot, we need to set up a MySql database. You can install MySql on your local machine or use a cloud-based MySql service like MySql Cloud Service or Amazon RDS. Once you have set up your MySql database, note down the connection details like host, port, username, and password.
2. Adding MySql dependencies to your Spring Boot project
The next step is to add MySql dependencies to your Spring Boot project. You can add the following dependencies in your pom.xml file:
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-data-jpa</artifactId>
</dependency>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</dependency>
3. Configuring MySql connection details in Spring Boot
To configure MySql connection details in Spring Boot, open your application.properties file and add the following properties:
spring.datasource.url=jdbc:mysql://<your-host>:<your-port>/<your-database-name>?useSSL=false&serverTimezone=UTC spring.datasource.username=<your-username> spring.datasource.password=<your-password> spring.jpa.hibernate.ddl-auto=update spring.jpa.show-sql=true spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5InnoDBDialect
Replace the placeholders with your MySql connection details.
4. Creating a MySql repository
Now that we have configured the MySql connection details in Spring Boot, we can create a MySql repository. Create a new Java interface and extend the JpaRepository interface provided by Spring Data JPA. Here is an example:
public interface EmployeeRepository extends JpaRepository<Employee, Long> {
}
5. Testing the MySql connection
Finally, we can test our MySql connection by creating a simple Spring Boot controller that uses our MySql repository. Here is an example:
@RestController
public class EmployeeController {
@Autowired
private EmployeeRepository employeeRepository;
@GetMapping("/employees")
public List<Employee> getEmployees() {
return employeeRepository.findAll();
}
}
In conclusion, connecting MySql with Spring Boot is a simple process that can help you create high-performing applications with ease. With these steps, you can easily integrate MySql in your Spring Boot applications. We hope this guide has been helpful to you. Happy coding!
