spark sql maven idea打包

前提 ，给 自己 的mysql  本地添加 远程访问权限

mysql> grant all privileges on *.* to root@"%" identified by 'root' with grant option;

mysql> flush privileges;

测试远程连接是否通？
mysql  -h10.2.6.60 -uroot -proot

package com.baoy.sql

import java.sql.DriverManager

import org.apache.spark.rdd.JdbcRDD
import org.apache.spark.{SparkConf, SparkContext}

/**

object Sql {

  def main(args: Array[String]) {
    val sparkConf = new SparkConf()
      .setAppName("streamsql")
    val sparkContext = new SparkContext(sparkConf)

    val rdd =new  JdbcRDD(sparkContext,
      () =>{
        Class.forName("com.mysql.jdbc.Driver").newInstance()
        DriverManager.getConnection("jdbc:mysql://10.2.6.60:3306/database", "root", "root")
      },
      "select count(*) from t_user where ?=?",
      1, 1, 1,
      r => r.getString(1)).cache()

    println(rdd.count())
    sparkContext.stop()
