DataX二次开发——（8）rdbms的达梦8数据库的支持
1 前言
目前GitHub上的DataX3.0开源版本，rdbms里面默认是达梦7的驱动，因此，如果像链接达梦8需要替换驱动。
2 驱动替换
1、下载Dm8JdbcDriver18-xxxx.jar，放到libs下面
2、修改maven依赖，注释dm7的驱动，改成达梦8
<dependency>
<groupId>com.damenggroupId>
<artifactId>Dm8JdbcDriver18artifactId>
<version>8.1.1.49version>
<scope>systemscope>
<systemPath>${basedir}/src/main/libs/Dm8JdbcDriver18-8.1.1.49.jarsystemPath>
dependency>
<dependencyManagement>
<dependencies>
<dependency>
<groupId>com.damenggroupId>
<artifactId>Dm8JdbcDriver18artifactId>
<version>8.1.1.49version>
dependency>
dependencies>
dependencyManagement>
3、重新打包编译
mvn -U clean package assembly:assembly -Dmaven.test.skip=true
3 读写达梦8的任务模板json
1、从达梦8读取写入到MySQL5.7模板

"setting": {

},

}
}
2、从MySQL5.7读取写入到达梦8模板
