NEST指定id

Posted 2022-11-09 chenyishi

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

[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; 
    

　　

3.初始化client时指定

            var node = new Uri("http://192.168.60.222:9200/");
            var settings = new ConnectionSettings(node)
                .DefaultIndex("employee")
                .DefaultMappingFor<employee>(x => x.IdProperty(p => p.last_name));
            client = new ElasticClient(settings);

　　

 

4.索引时指定

        public IIndexResponse IndexDoc(employee doc)
        
            return client.Index(doc,x=>x.Id(doc.last_name));
