MongoDB (3) Set Primary key

The primary key is set by the comment "@Id", and MongoDB automatically generates the primary key if the primary key is not set.

Import Org.springframework.data.annotation.Id;

public static class ordercomsumedto{
		
		@Id
		private String OrderNo;
		Private String Jnlno;
		Private String dateTime;
		
		Public String Getorderno () {
			return orderno;
		}
		public void Setorderno (String orderno) {
			This.orderno = OrderNo;
		}
		Public String Getjnlno () {
			return jnlno;
		}
		public void Setjnlno (String jnlno) {
			jnlno = Jnlno;
		}
		Public String GetDateTime () {
			return dateTime;
		}
		public void SetDateTime (String dateTime) {
			this.datetime = dateTime;
		}
