今天完成 nosql 实验：

mongdb

package opreation;
import java.util.ArrayList;
import java.util.List;

import com.mongodb.DB;
import org.bson.Document;


import com.mongodb.MongoClient;


import com.mongodb.client.MongoCollection;


import com.mongodb.client.MongoDatabase;


public class MongoTest {

    documents.add(document);

    collection.insertMany(documents);

    System.out.println(</span>"文档插入成功"<span style="color: rgba(0, 0, 0, 1)">);

}



}
