查看staticfs方案中gin启动日志可以看到，staticfs实际注册了GET、HEAD
[GIN-debug] GET    /static/*filepath         --> github.com/gin-gonic/gin.(*RouterGroup).createStaticHandler.func1 (3 handlers)
[GIN-debug] HEAD   /static/*filepath         --> github.com/gin-gonic/gin.(*RouterGroup).createStaticHandler.func1 (3 handlers)
因此直接用r.Any

		staticServer.ServeHTTP(c.Writer, c.Request)
