需要修改这个，dubbo3应该路径不一样了
// dubbo回放器中对dubbo框架路由
PluginClassRouting dubboRepeaterRouting = PluginClassRouting.builder()
.targetClass("org.apache.dubbo.rpc.model.ApplicationModel")
.classPattern("^org.apache.dubbo..*")
.identity("dubbo")
.matcher(Matcher.REPEATER)
.block(false)
.build();

我的日志为啥没生成啊，我指定的opt/log目录下，我新建的文件夹，就是那个log文件没新建，为啥没有日志文件生成啊
