官方文档：https://dangdangdotcom.github.io/elastic-job/

1.增加maven依赖

<dependency>				<groupId>com.dangdang</groupId>				<artifactId>elastic-job-lite-core</artifactId>				<version>2.0.5</version>			</dependency>			<!-- 使用sPRingframework自定义命名空间时引入 -->			<dependency>				<groupId>com.dangdang</groupId>				<artifactId>elastic-job-lite-spring</artifactId>				<version>2.0.5</version>			</dependency>2. 增加相应的xml配置
<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"       xmlns:reg="http://www.dangdang.com/schema/ddframe/reg"       xmlns:job="http://www.dangdang.com/schema/ddframe/job"       xsi:schemaLocation="http://www.springframework.org/schema/beans                        http://www.springframework.org/schema/beans/spring-beans.xsd                        http://www.dangdang.com/schema/ddframe/reg                        http://www.dangdang.com/schema/ddframe/reg/reg.xsd                        http://www.dangdang.com/schema/ddframe/job                        http://www.dangdang.com/schema/ddframe/job/job.xsd                        ">    <!--configure registry center -->    <reg:zookeeper id="regCenter" server-lists="10.0.11.175:2181,10.0.11.176:2181,10.0.11.177:2181" namespace="ycFeed-driverRate-job" base-sleep-time-milliseconds="1000" max-sleep-time-milliseconds="3000" max-retries="3" />    <!--configure job -->    <job:simple id="myElasticJob" class="com.yc.feed.web.cron.MyElasticJob" registry-center-ref="regCenter" cron="0 * * * * ?"   sharding-total-count="3" sharding-item-parameters="0=A,1=B,2=C" /></beans>3. 编辑相应的class
package com.yc.feed.web.cron;import com.dangdang.ddframe.job.api.ShardingContext;import com.dangdang.ddframe.job.api.simple.SimpleJob;import com.yc.feed.service.DriverRateService;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;/** * Created by lfeng on 2017/2/17. * * */@Componentpublic class MyElasticJob implements SimpleJob {    @Autowired    private DriverRateService driverRateService;    @Override    public void execute(ShardingContext context) {        int currentShard = context.getShardingItem();        int shardTotal = context.getShardingTotalCount();        driverRateService.runDriverCommentEvaluation(shardTotal,currentShard);    }}4.runDriverCommentEvaluation安装正常的service类写就可以，只需要修改相应的sql语句，增加查询条件
and mod(driver_id,shardTotal) = currentShard
