// Example of using DataSource as an alternative to Connection
import javax.sql.DataSource;
import java.sql.Connection;
import java.sql.SQLException;
public class DatabaseExample {
private DataSource dataSource;
public DatabaseExample(DataSource dataSource) {
this.dataSource = dataSource;
}
public void connectAndQuery() {
Connection connection = null;
try {
// Get a connection from the DataSource
connection = dataSource.getConnection();
// Perform database operations here
} catch (SQLException e) {
e.printStackTrace();
} finally {
// Always close the connection
if (connection != null) {
try {
connection.close();
} catch (SQLException e) {
e.printStackTrace();
}
}
}
}
