flink-提交jar包 submit 报错未序列化

flink-web控制台 submit jar包 报错堆栈(org.apache.flink.runtime.rest.handler.RestHandlerException: Could not execute application. at org.apache.flink.runtime.webmonitor.handlers.JarRunHandler.lambda$handleRequest$1(JarRunHandler.java:107) at )

（看不出来什么，我们需要去 flink-server 端看运行日志）

flink-server 服务端日志报错如下：(org.apache.flink.client.program.ProgramInvocationException: The main method caused an error: com.jdd.martech.export.kafka.config.KafkaConfig@3a786b17 is not serializable. The object probably contains or references non serializable fields.)
