远程分区:工作者端序列化问题
远程分区:工作者端序列化问题
提问于 2020-10-22 23:33:24
当运行worker but exception时，我使用了org.springframework.kafka.support.serializer.JsonDeserializer和org.apache.kafka.common.serialization.ByteArrayDeserializer，它们在主控端正常工作，但在worker端出现异常.最后我得到的原因是: java.lang.StackOverflowError: null

因为你使用的是json.StepExecution类和JobExecution类有双向的关系。因此，在尝试序列化要发送回应答通道的StepExecution对象时，它会导致无限递归。
