报出序列化异常

[PreSONG]

在用Oracle SQLServer Postgres几个Connector的时候，会抛出序列化异常，只有Mysql可以正常使用，是为啥呢

Exception in thread "main" org.apache.flink.api.common.InvalidProgramException: com.ververica.cdc.connectors.oracle.OracleValidator@65e2dbf3 is not serializable. The object probably contains or references non serializable fields.

已解决，POM文件中flink-connector-mysql-cdc的2.0.0版本与其他connector版本不一致导致的冲突，把mysql替换成相同版本即解决
