mongo数据库的增删改查

首先建立连接池

applicationContext.xml 配置  

1.表头 添加  

 xmlns:mongo="http://www.springframework.org/schema/data/mongo"

2.添加配置

<!-- Mongo DataSource -->

<mongo:mongo id="mongo" host="${mongo.host}" port="${mongo.port}">
<mongo:options/>
</mongo:mongo>

<mongo:db-factory id="mongoDbFactory" dbname="${mongo.dbName}" mongo-ref="mongo"/>

<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
<constructor-arg ref="mongoDbFactory"/>
</bean>

3. MongoAddKeywordService 添加

package com.honghailt.dataextracter.service;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.stereotype.Service;
import org.springframework.util.StringUtils;

import com.honghailt.dataextracter.model.MongoKeyword;
import com.mongodb.BasicDBObject;
import com.mongodb.DBCollection;
import com.mongodb.DBCursor;
import com.mongodb.DBObject;
@Service
public class MongoAddKeywordService {
     @Autowired
     private MongoTemplate mongoDb;

//         System.out.println("count:	"+sor.count());
//         long timeEnd =System.currentTimeMillis();
//         System.out.println(timeEnd-timeBegin);
//     }

更新操作
