1、从mysql8 往elasticsearch 7导入数据时，报错。
2、经查询，官方datax仅支持my5.x，以下为改造适配mysql 8.x 资料记录。
DataX支持mysql8.X https://blog.csdn.net/qq_41852045/article/details/108485749 https://blog.csdn.net/qq_42502354/article/details/108824761 https://blog.csdn.net/qq_38115310/article/details/108662659 Datax mysql8插件开发 https://blog.csdn.net/Loiterer_Y/article/details/115692010 https://blog.csdn.net/jason_9527/article/details/100995505 https://www.cnblogs.com/shuyao268/p/14879486.html https://www.cnblogs.com/harvey2017/p/12148090.html https://www.cnblogs.com/zifan/p/12550747.html https://rxf113.xyz/DataX%E5%AE%9E%E8%B7%B5/ https://www.jianshu.com/p/997727d488e6 http://www.manongjc.com/detail/14-iexdburliccybhe.html https://www.gitmemory.com/issue/alibaba/DataX/146/826093789 https://www.zybuluo.com/Catyee/note/1790630 https://github.com/alibaba/DataX/issues/677 https://github.com/alibaba/DataX/issues/1062 https://github.com/alibaba/DataX/issues/172 https://github.com/alibaba/DataX/issues/146 全文替换 convertToNull 为 CONVERT_TO_NULL; zeroDateTimeBehavior的值convertToNull 为 CONVERT_TO_NULL： 全文替换"com.mysql.jdbc.Driver"为"com.mysql.cj.jdbc.Driver"， 用maven重新编辑构建发布 mvn -U clean package assembly:assembly -Dmaven.test.skip=true 其中mysqlwriter 中： "jdbcUrl": "jdbc:mysql://192.125.30.169:3306/wjybjy?useUnicode=true&characterEncoding=gbk&useSSL=false&serverTimezone=UTC", 比如：python datax.py file.json ， 则file.json的配置项： "jdbcUrl":"jdbc:mysql://${writer_gateway}/oms?useUnicode=true&characterEncoding=UTF-8&useSSL=false", 第五步jdbc链接追加useSSL=false设置： 比如：python datax.py file.json ， 则file.json的配置项： "jdbcUrl":"jdbc:mysql://${writer_gateway}/oms?useUnicode=true&characterEncoding=UTF-8&useSSL=false", "jdbcUrl": "jdbc:mysql://192.125.30.169:3306/wjybjy?useUnicode=true&characterEncoding=gbk&useSSL=false&serverTimezone=UTC", 需要注意的几点：1.writer中不能带[]; reader中必须带[]。 2.需要加&useSSL=false&serverTimezone=UTC" 3."setting": { "speed": { "channel": 1 } },
