一、准备好hive的环境，创建表(例如userinfo),添加数据。

create table userinfo(x string, y string);
insert into userinfo values('tju','beiyang');

二、启动hive服务
hive --service hiveserver2
三、项目中添加依赖

        <dependency><groupId>org.apache.hive</groupId><artifactId>hive-jdbc</artifactId><version>3.1.2</version><exclusions><exclusion><groupId>org.eclipse.jetty</groupId><artifactId>jetty-runner</artifactId></exclusion></exclusions></dependency>

四、读取数据demo:

package cn.edu.tju;import java.sql.*;public class HiveJdbcClient {private static String driverClassName = "org.apache.hive.jdbc.HiveDriver";     //hive的驱动public static void main(String[] args) throws SQLException {try {Class.forName(driverClassName);} catch (ClassNotFoundException e) {e.printStackTrace();System.exit(1);}Connection con = DriverManager.getConnection("jdbc:hive2://xxx.xxx.xxx.xxx:10000/default", "", "");Statement stmt = con.createStatement();String tableName = "userinfo";// selectString sql = "select * from " + tableName;ResultSet res = stmt.executeQuery(sql);while (res.next()) {System.out.println(String.valueOf(res.getString(1)) + " " + res.getString(2));}}
}
