DataSource dataSource = DruidDataSourceFactory.createDataSource(prop);

The above code creates a new instance of a DruidDataSource object by calling the createDataSource() method of the DruidDataSourceFactory class, passing in a Properties object named prop as an argument. The prop object contains a set of configuration properties that define the connection parameters for the data source, such as the JDBC URL, username, password, and other settings. Once the data source is created, it can be used to obtain a connection to a database for executing SQL statements or performing other database operations.
