Question

在OSGi包（称为net.beaconcontroller.cluster）中，我有org.jgroups.blocks.ReplicatedHashMap类型<Long, net.beaconcontroller.cluster.ControllerInfo>。问题是，在调度期间（即远程端ControllerInfo的反序列化）JGroups抱怨ClassNotFoundException。（附加了堆栈跟踪。）添加

Thread.currentThread().setContextClassLoader(Cluster.class.getClassLoader())

到net.beaconcontroller.cluster包的startUp（）方法的行确实没有效果。我可能会缺少什么？

您是否尝试添加捆绑包的MANIFEST.MF：

Import-Package: net.beaconcontroller.cluster

在OSGi包中反序列化时ClassNotFoundException
