1、從mysql8 往elasticsearch 7匯入資料時，報錯。

2、經查詢，官方datax僅支援my5.x，以下為改造適配mysql 8.x 資料記錄。

DataX支援mysql8.X

全文替換 convertToNull 為 CONVERT_TO_NULL;
zeroDateTimeBehavior的值convertToNull 為 CONVERT_TO_NULL：
​ 全文替換
 
"com.mysql.jdbc.Driver"為"com.mysql.cj.jdbc.Driver"，

用maven重新編輯構建釋出
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 ， 則file.json的配置項：
"jdbcUrl":"jdbc:mysql://${writer_gateway}/oms?useUnicode=true&characterEncoding=UTF-8&useSSL=false",
第五步jdbc連結追加useSSL=false設定：
比如：python datax.py file.json ， 則file.json的配置項：
"jdbcUrl":"jdbc:mysql://${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",

需要注意的幾點：1.writer中不能帶[]; reader中必須帶[]。
2.需要加&useSSL=false&serverTimezone=UTC"
3."setting": {
"speed": {
"channel": 1
}
},
