hive+jdbc

1、注：先开起 hiveserver2 服务

 2、源代码

package com.me.jdbc;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;

public class HiveJdbc {
    
    public static void main(String[] args) throws Exception {
        
        //①加载驱动
        //Class.forName("org.apache.hive.jdbc.HiveDriver");
        
        //②创建连接
        Connection connection = DriverManager.getConnection("jdbc:hive2://hadoop101:10000", "root", "lxy208751");
        
        // ③准备SQL
        String sql="select * from default.person";
        
        // ④预编译sql
        PreparedStatement ps = connection.prepareStatement(sql);
        
        // ⑤执行sql
        ResultSet resultSet = ps.executeQuery();
        
        while(resultSet.next()) {
            
            System.out.println("name:"+resultSet.getString("name")+"---->age:"+
            resultSet.getInt("age"));
            
        }
        
        
    }

}
