MongoDB_Java连接mongo 使用Java多条件查询mongo数据

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
