多线程创建connection连接hbase

public class Getconnection {
    //声明一个静态属性
    public static Connection connection = null;

    static {
        //创建连接
        try {
            //使用读取本地文件的方式添加参数
            connection = ConnectionFactory.createConnection();

        } catch (IOException e) {
            e.printStackTrace();
        }

//        //创建异步连接
//        CompletableFuture<AsyncConnection> asyncConnection = ConnectionFactory.createAsyncConnection();

    }

    public static Connection getConnection(){
        return connection;
    }
