Phoenix HBase Java常用的API

下面是Java通过jdbc向Phoenix取hbase数据的代码

package org.example;
import org.apache.phoenix.jdbc.PhoenixDriver;


import org.junit.Test;
import java.sql.*;

public class HbasePhoenixJDBCTest {
    
    

    @Test
    public static void main(String[] args) throws SQLException {
    
    
        Connection connection = null;
        PreparedStatement ps = null;
        try {
    
    
            Class.forName(PhoenixDriver.class.getName());
            connection = DriverManager.getConnection("jdbc:phoenix:node1.itcast.cn:2181");
            ps = connection.prepareStatement( "select user_id,payway,category from order_info");
            ResultSet rs = ps.executeQuery();
            while(rs.next()) {
    
    
                System.out.println(
                        rs.getString("USER_ID")+"\t"+
                                rs.getString("PAYWAY")+"\t"+
                                rs.getString("CATEGORY"));
            }
        }catch (Exception e){
    
    
            e.printStackTrace();
        }finally {
    
    
            if(ps != null) ps.close();
            if(connection != null) connection.close();
        }

    }
}
