Fixes #2590
Describe how you did it
原本 com.alibaba.csp.sentinel.dashboard.util.ClusterEntityUtils的wrapToClusterGroup 中的map中的Key用的是实例的ip,并非ip:port,导致同机器下不同端口时,同IP的信息会被覆盖。
只需修改 com.alibaba.csp.sentinel.dashboard.util.ClusterEntityUtils的wrapToClusterGroup方法,将Key改为ip port,使其可以正常返回结果
Describe how to verify it
部署Dashboard之后无论先从哪个实例删除均成功即可
