如何通过java代码对kylin进行cube build

通常是用于增量

代码如下：

package com.dlht.kylinDemo;

import java.io.BufferedReader;

import java.io.FileNotFoundException;

import java.io.IOException;

import java.io.InputStreamReader;

import java.io.PrintWriter;

import java.net.HttpURLConnection;

import java.net.MalformedURLException;

import java.net.URL;

import org.apache.commons.codec.binary.Base64;

public class BuildTest {

	static String ACCOUNT = "ADMIN";

	static String PWD = "KYLIN";

	static String PATH = "http://192.168.22.102:7070/kylin/api/cubes/KPI_Base_DataCppaCrcCount_test_Cube/rebuild";

	public static void main(String[] args) {

		System.out

				.println(Put(

						PATH,

						"{\"startTime\": 1451750400000,\"endTime\": 1451836800000,\"buildType\": \"BUILD\"}"));

	}

	public static String Put(String addr, String params) {

		String result = "";

		try {

			URL url = new URL(addr);

			HttpURLConnection connection = (HttpURLConnection) url

					.openConnection();

			connection.setRequestMethod("PUT");

			connection.setDoOutput(true);

			String auth = ACCOUNT + ":" + PWD;

			String code = new String(new Base64().encode(auth.getBytes()));

			connection.setRequestProperty("Authorization", "Basic " + code);

			connection.setRequestProperty("Content-Type",

					"application/json;charset=UTF-8");

			PrintWriter out = new PrintWriter(connection.getOutputStream());

			out.write(params);

			out.close();

			BufferedReader in;

			try {

				in = new BufferedReader(new InputStreamReader(

						connection.getInputStream()));

			} catch (FileNotFoundException exception) {

				java.io.InputStream err = ((HttpURLConnection) connection)

						.getErrorStream();

				if (err == null)

					throw exception;

				in = new BufferedReader(new InputStreamReader(err));

			}

			StringBuffer response = new StringBuffer();

			String line;

			while ((line = in.readLine()) != null)

				response.append(line + "\n");

			in.close();

			result = response.toString();

		} catch (MalformedURLException e) {

			System.err.println(e.toString());

		} catch (IOException e) {

			System.err.println(e.toString());

		}

		return result;

	}

}

这是官方教程：http://kylin.apache.org/docs15/howto/howto_use_restapi.html#build-cube 　

默认帐号密码就是ADMIN KYLIN

在starttime和endtime填写时间，就是build的开始结束时间，注意starttime肯定要大于endtime，同时还要注意，starttime必须要大于历史
