在mongo shell中的查询语句是这样的..
db.user.find({"age":{"$gt":5,"$lt":14}})我们用Java连接mongo来实现.mongo库中的数据
代码
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; /** * Java多条件查询mongo */ public class JavaManyConditionsQuery { public static void main(String[] args) { try { MongoClient mongoClient = new MongoClient("192.168.125.125", 27017); DB db = mongoClient.getDB("test"); DBCollection dbCollection = db.getCollection("user"); //将两个并联的查询条件放入一个里面. DBObject dbQuery = new BasicDBObject(); dbQuery.put("$gt", 5); dbQuery.put("$lt", 14); DBObject query = new BasicDBObject("age",dbQuery); DBCursor dbCursor = dbCollection.find(query); while (dbCursor.hasNext()) { System.out.println(dbCursor.next()); } } catch (Exception e) { e.printStackTrace(); } } }查询结果
