}其中routerSlices是一个切片，他应该使用深拷贝，否则修改原始hb会修改新的hb，例如
func HeatBeatDefaultHandle111(req ziface.IRequest) {
zlog.Ins().InfoF("Recv Heartbeat from %s, MsgID = %+v, Data = %s",
req.GetConnection().RemoteAddr(), req.GetMsgID(), string(req.GetData()))
}
func TestHeartbeatChecker_Clone(t *testing.T) {
hb := NewHeartbeatChecker(1)
//t.Log(len(hb.RouterSlices()), cap(hb.RouterSlices()))
new_hb := hb.Clone()
new_hb.BindRouterSlices(123,HeatBeatDefaultHandle)
new_hb.BindRouterSlices(123,HeatBeatDefaultHandle)
//t.Log(len(new_hb.RouterSlices()), cap(new_hb.RouterSlices()), new_hb.RouterSlices())
new_new_hb := new_hb.Clone()
//t.Log(len(new_new_hb.RouterSlices()), cap(new_new_hb.RouterSlices()),new_new_hb.RouterSlices())
new_new_hb.BindRouterSlices(123,HeatBeatDefaultHandle)
t.Log("new_new_hb",len(new_new_hb.RouterSlices()), cap(new_new_hb.RouterSlices()),new_new_hb.RouterSlices())
t.Log("new_hb",len(new_hb.RouterSlices()), cap(new_hb.RouterSlices()),new_hb.RouterSlices())
new_hb.BindRouterSlices(123,HeatBeatDefaultHandle111)
t.Log("new_new_hb",len(new_new_hb.RouterSlices()), cap(new_new_hb.RouterSlices()),new_new_hb.RouterSlices())
t.Log("new_hb",len(new_hb.RouterSlices()), cap(new_hb.RouterSlices()),new_hb.RouterSlices())
}进行测试会发现，修改原始new_hb，new_new_hb会修改
