Question

我正在Spring Boot v.2.0.3.RELEASE上运行hazelcast-jet-spring工件（不是hazelcast-jet）v.0.6.1，并收到此错误：

Caused by: java.lang.IllegalArgumentException: DataSerializableFactory[-45] is already registered! com.hazelcast.internal.journal.EventJournalDataSerializerHook$1@4a3e1b5d -> com.hazelcast.journal.EventJournalDataSerializerHook$1@587df3e4

com.hazelcast.internal.journal.EventJournalDataSerializerHook com.hazelcast.journal.EventJournalDataSerializerHook

看起来两个名称相同但位于不同程序包中的类处于冲突状态。您能建议如何避免这种情况吗？

谢谢！

我不得不对Hazelcast 3.10使用显式依赖。

解决了！
