前一篇文章中介紹了在window系統(tǒng)下部署mongodb集群，按照教程一步步實(shí)現(xiàn)的話應(yīng)該都可以在本機(jī)部署成功了，上篇文章末尾也提到了，想集成到SSM框架中去，網(wǎng)上資料基本都是單個(gè)mongodb數(shù)據(jù)庫的，集群的例子很少，有幾個(gè)也殘缺不全，抽時(shí)間研究了一下，最終在SSM框架中成功集成，在文章末尾我會把spring中集成的源代碼發(fā)一下，SSM框架中集成基本類似，其實(shí)主要就是jar包問題，單個(gè)mongodb集成實(shí)例，這篇文章寫得很詳細(xì)，我也是根據(jù)這篇文章改編的。
單個(gè)數(shù)據(jù)庫連接：<mongo:mongo host="192.168.1.141" port="27017"/>
集群連接：
[java] view plain
copy <context:property-placeholder?location="classpath*:mongodb.properties"?/>????????????<mongo:mongo?id="mongo"?replica-set="${mongo.config.replica.set.address}">?????????????<mongo:options?connections-per-host="100"??????threads-allowed-to-block-for-connection-multiplier="50"??????auto-connect-retry="true"/>?????????????</mongo:mongo>???
集群與單個(gè)連接相比只是加了個(gè)replice-set屬性，但是因?yàn)閖ar包的問題可能導(dǎo)致不支持，
修改這個(gè)jar包后會發(fā)現(xiàn)各種jar包報(bào)錯(cuò)，一個(gè)一個(gè)改下來，最后如下：
特別要注意的是:jar包不同配置文件中的寫法是不一樣的，同時(shí)，在代碼中的增刪改查的方法參數(shù)的順序也是不一樣的，特別蛋疼。。。。
下面上集群的目錄樹結(jié)構(gòu)：
首先是MongoTest類，程序入口：
[java] view plain
copy package?com.mongo.test;????import?java.util.List;??import?org.apache.commons.logging.Log;??import?org.apache.commons.logging.LogFactory;??import?org.springframework.context.ApplicationContext;??import?org.springframework.context.support.ClassPathXmlApplicationContext;??import?com.mongo.bean.Person;??import?com.mongo.dao.AbstractRepository;??import?com.mongo.dao.impl.PersonRepository;??????????public?class?MongoTest?{????????private?static?Log?log?=?LogFactory.getLog(MongoTest.class.getName());????????????private??AbstractRepository?pr=null;??????????????????public?void?init(){???????????log.debug("開始啟動");???????????ApplicationContext?ctx?=?new?ClassPathXmlApplicationContext("applicationContext.xml");????????????pr=?(PersonRepository)ctx.getBean("personRepository");??????}????????????public?void?insert(){??????????for(int?i=0;i<5;i++){??????????????Person?p=new?Person("name"+i,i);???????????????pr.insert(p);???????????????log.debug("添加成功");??????????}????????????????}????????????public?void?deleteOne(){??????????String?id="57edd4506ab8e4b1f9e99e02";??????????pr.removeOne(id);??????????Person?p=?pr.findOne(id);??????????log.debug(p);??????}????????????public?void?removeAll(){??????????pr.removeAll();??????}????????????public?void?findOne(){??????????String?id="57edd4506ab8e4b1f9e99e01";??????????Person?p=?pr.findOne(id);??????????log.debug(p);??????}????????????public?void?listAll(){??????????List<Person>?list=pr.findAll();??????????log.debug("查詢結(jié)果如下:");??????????for?(Person?p:list){??????????????log.debug(p.toString());??????????}??????}????????????public?void?findAndModify(){??????????String?id="57f9f163d12818b23aa3dbf9";??????????Person?p=?pr.findOne(id);??????????p.setName("upda");??????????pr.insert(p);??????}??????????????????public?void?start(){??????????init();??????????????????listAll();????????}??????????????????public?static?void?main(String[]?args)?{??????????MongoTest?t=new?MongoTest();??????????t.start();??????}????}??
在mongodb環(huán)境搭建好之后，程序運(yùn)行首先運(yùn)行insert（）方法，，插入幾條數(shù)據(jù)，然后用可視化工具連上mongodb庫看下是否數(shù)據(jù)已經(jīng)插入，在執(zhí)行l(wèi)istAll（），查詢所有方法，看下控制臺是否有數(shù)據(jù)輸出，如果能正常輸出，就說明你這個(gè)集成成功了一半了，關(guān)閉一個(gè)庫試試，數(shù)據(jù)如果還有的話，那肯定是已經(jīng)集成成功了。繼續(xù)上代碼：

testrs是上一篇中集群給每個(gè)服務(wù)器添加的自定義標(biāo)示，有的配置文件中會用到，我這里沒用到
dbTest是我的數(shù)據(jù)庫名，也是沒用到，我這個(gè)配置文件只是一個(gè)簡化版的，很多參數(shù)都省略了， 實(shí)際上只需要一個(gè)地址就行，單機(jī)和集群配置文件的區(qū)別就是這個(gè)
