mongodb java驱动包下载：https://github.com/mongodb/mongo-java-driver/downloads

本测试用例包括：查询数据库、查询聚类集合、查询数据、添加数据、添加多条数据、删除数据、修改数据操作，更多操作请使用者以此类推。

工程目录结构如图：

mongodb数据库管理类：

import com.mongodb.Mongo;/** * mongodb管理器 *  * @author jacklin *  */public class MongodbManager {private static Mongo mg = null;/** * 获取mongodb *  * @return */public synchronized static Mongo getMongo() {if (mg == null) {try {mg = new Mongo("localhost", 27017);} catch (Exception e) {e.printStackTrace();}}return mg;}}
