What are the steps for configuring a datasource in Spring Boot?

Setting up the Spring Boot data source requires the following steps:

1. Introduce dependencies: Add Spring Boot and database-related dependencies to the pom.xml file, such as spring-boot-starter-data-jpa and spring-boot-starter-jdbc.
2. Configure database connection: Set up database connection information in the application.properties or application.yml file, including database URL, username, password, etc.
3. Configure DataSource Bean: In a Spring Boot configuration class, use the @Bean annotation to configure a DataSource Bean. You can use the default DataSource provided by Spring Boot, such as HikariCP, or you can customize a DataSource.
4. Configure JPA properties (optional): If using JPA for data access, you can configure JPA-related properties such as entity class scanning paths, database dialect, automatic table creation, etc.

The above are the basic steps to configure the data source in Spring Boot, and the specific configuration can be adjusted according to the specific requirements.
