简介:

DataX 是一个异构数据源离线同步工具,致力于实现包括关系型数据库(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功能。github地址: https://github.com/alibaba/DataX

目前dataX不支持mysql8.X,需要修改源码,修改的地方

  • OriginalConfPretreatmentUtil类中引用的DataBaseType的追加参数,mysql8的zeroDateTimeBehavior=convertToNull修改为zeroDateTimeBehavior=CONVERT_TO_NULL

    修改前:suffix = "yearIsDateType=false&zeroDateTimeBehavior=convertToNull&tinyInt1isBit=false&rewriteBatchedStatements=true";

    修改后: suffix = "yearIsDateType=false&zeroDateTimeBehavior=CONVERT_TO_NULL&tinyInt1isBit=false&rewriteBatchedStatements=true";

  • mysql驱动,在mysql reader和writer的pom文件修改为

        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>8.0.11</version>
        </dependency>
  • clean install 跳过测试

  • 将reader和writer生成的target下面的datax的plugin拷贝到core工程项目和bin同级的plugin(源码生成是没有的,新建)

  • 目录级别

  • json模板
