NEST指定id

1.默认以Id属性为Id，无Id属性则自动生成

 

2.可通过属性标签指定Id

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

[ElasticsearchType(IdProperty = nameof(last_name))]     public class employee     {         public Guid Id { get; set; } = Guid.NewGuid();         public string first_name { get; set; }         public string last_name { get; set; }         public int age { get; set; }         public string about { get; set; }         public List<string> interests { get; set; }           public employeedto dto { get; set; }     }         public class employeedto     {         public Guid Id { get; set; }     }
