import com.alibaba.druid.pool.DruidDataSourceFactory;

`import com.alibaba.druid.pool.DruidDataSourceFactory;`是Java中导入Druid连接池的工厂类。Druid连接池是阿里巴巴开源的一个高效、可靠的数据库连接池。通过使用Druid连接池，可以大大提高数据库连接的效率和稳定性。以下是一个使用Druid连接池获取数据库连接的例子：

import com.alibaba.druid.pool.DruidDataSourceFactory;
import javax.sql.DataSource;
import java.io.IOException;
import java.io.InputStream;
import java.sql.Connection;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.util.Properties;

public class Test {
    public static void main(String[] args) throws SQLException, IOException {
        // 加载配置文件
        Properties properties = new Properties();
        InputStream inputStream = Test.class.getClassLoader().getResourceAsStream("druid.properties");
        properties.load(inputStream);

        // 获取数据源
        DataSource dataSource = DruidDataSourceFactory.createDataSource(properties);

        // 获取连接
        Connection connection = dataSource.getConnection();

        // 执行查询
        Statement statement = connection.createStatement();
        ResultSet resultSet = statement.executeQuery("SELECT * FROM user");

        // 处理结果集
        while (resultSet.next()) {
            System.out.println(resultSet.getString("name"));
        }

        // 关闭连接
        resultSet.close();
        statement.close();        connection.close();
    }
}
