一定要看看网上代码的发布的时间，现在<mongo:mongo>这样的标签已经不能用了，如果要带验证的登录的话，记得使用这个
<mongo:mongo-client host="服务器地址" port="端口" credentials="账户:密码@数据库" id="mongo">
在credentials="账户:密码@数据库"当中，按照上述格式输入

package kc.model;

import lombok.Data;
import org.springframework.data.annotation.Id;
import org.springframework.data.mongodb.core.mapping.Document;

import java.util.Map;

@Document(collection = "cuisine")
@Data
public class CuisineEntity {
    @Id //注意这个id是系统的id，如果你自己有一个id 的属性的话，那就应该多加一个_id来保存MongoDB系统的id
    private String _id;
    private String id;
    private String caiming;
    private String chengpin;
    private String[] biaoqian;

    @Override
    public String toString(){
        return caiming;
    }
}
