if it confirmed ,i will fix it so quickly!

OK.

When you try to fix it. Please do some test for compatibility test with old version nacos server from 1.1.3 to 1.3.2

java class name:com.alibaba.nacos.api.naming.pojo.ServiceInfo
method:

public ServiceInfo(String key) {  
    int maxIndex = 2;  
    int clusterIndex = 1;
    int serviceNameIndex = 0;

    String[] keys = key.split(Constants.SERVICE_INFO_SPLITER);
    if (keys.length >= maxIndex) {
        this.name = keys[serviceNameIndex];
        this.clusters = keys[clusterIndex];
    }

    this.name = keys[0];
}`

When read cache file from disk throuth method DiskCache.read(String cacheDir), the method use constructor public ServiceInfo(String key) to instantiate ServiceInfo,you can check the code in file DiskCache of line 111.
I give a example of the input param for method public ServiceInfo(String key) like group@@service_name@@clusters.

You can see when spilt with @@ ,the clusterIndex should be 2 not 1, and the serviceNameIndex should be 1 not 0,and the groupName can be fill with data of index=0.

you should consider 'key' in different situations:

1. name
2. group@@name
3. group@@name@@cluster
