Datax是一个开源的数据交换工具，支持关系型数据库(MySQL、Oracle等)、HDFS、Hive、ODPS、HBase、FTP等各种异构数据源之间稳定高效的数据同步，很多商业化的大数据平台也会将Datax作为ETL组件。
本文介绍将datax集成到springboot中进行开发。

Demo代码：https://gitee.com/zengzhenhui/springboot-datax

一、下载官方安装包

1.下载地址：http://datax-opensource.oss-cn-hangzhou.aliyuncs.com/datax.tar.gz
2.解压后保留conf、job、lib、plugin目录，其余目录和文件可以删掉。其中plugin目录只保留需要的插件。
3.将datax目录移动到springboot项目目录下

二、导入必要的依赖

pom.xml中加入以下依赖，其中版本号为0.0.1-SNAPSHOT的依赖包可从datax压缩包中获取，需要安装到本地仓库或上传到私有仓库。

        <dependency>
            <groupId>com.alibaba.datax</groupId>

        </dependency>

三、执行函数

    @Value("${datax.home}")
    private String dataxHome;
	
    public void execute(String jobConfig) {
        System.setProperty("datax.home", dataxHome);
        System.setProperty("now", LocalTime.now().toString());
        String[] dataxArgs = {"-job", dataxHome + "/job/" + jobConfig, "-mode", "standalone", "-jobid", "-1"};
        try {
            Engine.entry(dataxArgs);
        } catch (Throwable e) {
            e.printStackTrace();
        }
    }

• dataxHome参数为前面下载的datax目录路径；
• jobConfig 参数是配置数据同步任务的json文件，放在${dataxHome}/job目录下，格式为xxx.json；
