java.lang.ClassNotFoundException： net.spy.memcached.compat.log.SLF4JLogger
2022-09-04 22:51:31
我添加到Java opts -Dnet.spy.log.LoggerImpl=net.spy.memcached.compat.log.SLF4JLogger，以设置spymemcached使用slf4j作为记录器。但是我在tomcat6日志中收到以下警告，我对错误感到困惑
net.spy.memcached.compat.log.SLF4JLogger not found while initializing net.spy.compat.log.LoggerFactory java.lang.ClassNotFoundException: net.spy.memcached.compat.log.SLF4JLogger
怎么可能找不到类SLF4JLogger。它正在初始化LoggerFactory意味着net.spy软件包可用，更一般地说，间谍memcache jar可用。那么它怎么能找不到另一个类。
