kylin 通过jdbc驱动进行sql查询

1、创建maven工程，添加依赖<!-- https://mvnrepository.com/artifact/org.apache.kylin/kylin-jdbc -->
<dependency>
<groupId>org.apache.kylin</groupId>
<artifactId>kylin-jdbc</artifactId>
<version>2.2.0</version>
</dependency>2、编写代码
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.util.ArrayList;
import java.util.List;
import java.util.Properties;

import org.apache.kylin.jdbc.Driver;

public class Query {
public static void main(String[] args) throws Exception {
Driver driver = (Driver) Class.forName("org.apache.kylin.jdbc.Driver").newInstance();
Properties info = new Properties();
info.put("user", "ADMIN");
info.put("password", "KYLIN");
Connection conn = driver.connect("jdbc:kylin://ip:port/projectName", info);
String sqlStr = "select distinct userid from dbName.sheetName where day_time <? limit 10000";
PreparedStatement ps = conn.prepareStatement(sqlStr);
ps.setString(1, "2018-02-01");
ResultSet resultSet = ps.executeQuery();
List uidList = new ArrayList();
while (resultSet.next()) {
uidList.add(resultSet.getString(1));
}
uidList.forEach(uid -> System.out.println(uid));
}
}3、查询结果



4、前期准备
在kylin下创建Project、model、cube；最好通过在web界面能够进行成功的sql查询后，再利用jdbc进行sql查询



5、参考
