当本地同时启动服务端和客户端的时候就可能产生这个问题。
解决方案Dubbo通过注册中心发现服务,发现的服务Dubbo同时也会保存到本地缓存一份,缓存的好处有很多,比如不需要每次使用的时候都通过注册中心获取,注册中心不可用了,不影响消费端的调用,因为本地缓存了一份服务提供者列表。Dubbo本地缓存默认采用的文件,会根据注册中心自动在当前用户目录下生成一个缓存文件,类似/home/newad/.dubbo/dubbo-registry-*.*.*.*.cache,星号表示注册中心的IP地址,当同一台机器上同时启动多个进程,就会出现多个进程争夺此文件的写入权限,觖此问题的方法也很简单,日志里面都说了重新配置一下这个缓存文件就。
主要在启动脚本里面添加配置: -Ddubbo.registry.file=C:\Users\dell.dubbo\dubbo-registry-192.168.1.62-junit.cache 文件名自己配置一个 -Ddubbo.registry.file=C:\Users\dell.dubbo\dubbo-registry-192.168.1.62-junit.cache
