在mongo shell中的查詢語句是這樣的..

db.user.find({"age":{"$gt":5,"$lt":14}})

mongo庫中的資料

程式碼

package com.java.module.mongo.mongo_test_1;

import com.mongodb.BasicDBObject;
import com.mongodb.DB;
import com.mongodb.DBCollection;
import com.mongodb.DBCursor;
import com.mongodb.DBObject;
import com.mongodb.MongoClient;

            MongoClient mongoClient = new MongoClient("192.168.125.125", 27017);
            DB db = mongoClient.getDB("test");
            DBCollection dbCollection = db.getCollection("user");

            //將兩個並聯的查詢條件放入一個裡面.

            dbQuery.put("$gt", 5);
