java.lang.ClassNotFoundException: org.apache.commons.jcs3.utils.discovery.UDPDiscoveryMessage

如何解决java.lang.ClassNotFoundException: org.apache.commons.jcs3.utils.discovery.UDPDiscoveryMessage

我正在尝试使用 jcs 设置横向 TCP 缓存。 我已经添加了 commons-jcs3-core-3.0.jar 作为依赖项。

但是得到 java.lang.classNotFoundException: org.apache.commons.jcs3.utils.discovery.UDPdiscoveryMessage
