Spring 引导：无法实例化 [com.hazelcast.jet.JetInstance]

Question

我是运行 hazelcast-jet-spring 神器（不是 hazelcast-jet）v.0.6.1 Spring Boot v.2.0.3.RELEASE并收到此错误：

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

    at com.hazelcast.jet.Jet.newJetInstance(Jet.java:57)

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

看起来2个类同名但位于不同的包中处于冲突状态。你能告诉我如何避免这种情况吗？

谢谢！

我不得不使用对 Hazelcast 3.10 的显式依赖。

已解决！
