将ObjectId转换为Spring数据中的字符串

import org.bson.types.ObjectId;

public class ObjectIdToStringExample {
    public static void main(String[] args) {
        ObjectId objectId = new ObjectId();
        String objectIdString = objectId.toString();
        System.out.println("ObjectId as String: " + objectIdString);
    }
}

import org.bson.types.ObjectId;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

@Document(collection = "users")
public class User {
    @Id
    private ObjectId id;
    private String name;
    // other fields, getters, and setters
}
