Java HazelCast NoClassDef错误

我在我的应用程序中使用HazelCast，它运行良好。由于系统维护，我不得不取消部署并重新部署应用程序。现在，当我尝试引入应用程序时，我的hazelcast中不断出现这个错误。有人能帮我吗？我没有对我的申请做任何更改。这只是一次Windows升级，需要重新启动服务器

我猜您的类路径中可能有多个版本的Hazelcast的jar。由于类路径通常是随机顺序的，您可能会得到一个JARA类和一个JARB类，以此类推。请查看是否有干净的类路径。应该只有一个Hazelcast版本。

它与Java类加载相关

它与Hazelcast本身无关，而是与您的环境有关。 您正在运行一个JEE服务器，并且在有效的类路径中肯定有多个Hazelcast副本。 它们相互干扰（可能是由不同的类加载器加载）

如果重新启动或热部署应用程序，也可能发生这种情况。

多个版本正在运行。设法把它弄干净了。谢谢多个版本正在运行。设法把它弄干净了。谢谢
