我刚刚开始在 Spring Boot 中使用 Kafka 并想发送和使用 JSON 对象。
当我尝试使用来自 Kafka 主题的消息时，出现以下错误：
org.apache.kafka.common.errors.SerializationException: Error deserializing key/value for partition dev.orders-0 at offset 9903. If needed, please seek past the record to continue consumption.
Caused by: java.lang.IllegalArgumentException: The class 'co.orders.feedme.feed.domain.OrderItem' is not in the trusted packages: [java.util, java.lang]. If you believe this class is safe to deserialize, please provide its name. If the serialization is only done by a trusted source, you can also enable trust all (*).
