mongo使用java实现简单增删查改操作

新建maven工程并添加依赖包

修改pom.xml

添加依赖包

    
      org.mongodb
      mongo-java-driver
      3.2.2
    

编写MongoDemo类

package nj.zb.mongtest;

import com.mongodb.MongoClient;
import com.mongodb.MongoCredential;
import com.mongodb.ServerAddress;
import com.mongodb.client.MongoCollection;
import com.mongodb.client.MongoDatabase;
import com.mongodb.client.model.Filters;
import org.bson.Document;
import org.bson.conversions.Bson;

import java.util.ArrayList;
import java.util.List;

    }

进mongodb查看结果

创建表的结果

插入数据的结果

也可以通过pretty()方法查看详细（只是看的比较舒服哈哈)

查询全部及多条件查询

其实只是在控制台上输出（通过toJson输出为String类型）

更新数据的结果

删除结果

多条件删除的结果

ps：利用java进行mongodb的操作基本完成！！！
ps：望多多支持，后续更新中。。。
