HazelCast NoClassDef错误

标签： java hazelcast

我在我的应用程序中使用HazelCast，运行良好。由于系统维护，我不得不取消部署和重新部署应用程序。现在，当我尝试启动应用程序时，我不断在我的hazelcast中收到此错误。有人可以帮我弄这个吗？我没有更改我的申请。它只是一个Windows升级，需要服务器重启。

2 个答案:

答案 0 :(得分：1)

我猜你可能在你的类路径中有多个版本的Hazelcast的JAR。由于类路径通常是随机顺序，因此您可能会获得一个JAR A类和一个JAR B类，依此类推。请查看您是否有干净的类路径。只应该有一个Hazelcast版本。

答案 1 :(得分：1)

它与Java类加载有关...

它与Hazelcast本身无关，但与您的环境无关。 您正在运行JEE服务器，并且在您的有效类路径中肯定有多个Hazelcast副本。 它们相互干扰（可能是每个由不同的类加载器加载的地方）。

OR

如果您重新启动或热部署了应用程序，也会发生这种情况。
