SpringMVC整合MongoDB开发

架构搭建

[日期：2015-02-28]来源：Linux社区  作者：dennisit[字体：大 中 小]

系统环境:

操作系统:  windows xp

数 据 库:  mongodb2.0.6

驱 动 包: Spring3.1.2 + mongodb2.7.3 + spring-data-mongodb1.0.1

说明: 对于xp系统用户,在执行mongod.exe安装mongodb时 出现,无法定位程序输入点 InterlockedCompareExchange64 于动态链接库KERNEL32.dll上,这是因为最新的开发分支已经不再支持xp.也就是说你的mongodb安装包不支持xp系统.V2.0.6是最新也是最后一个新版本支持xp.所以笔者使用数据库为2.0.6

项目结构:

配置说明:
Web.xml文件配置spring相关与springmvc相关.

mongodb的属性配置文件mongodb.properties

mongo.hostport=127.0.0.1:27017mongo.connectionsPerHost=8mongo.threadsAllowedToBlockForConnectionMultiplier=4#连接超时时间mongo.connectTimeout=1000#等待时间mongo.maxWaitTime=1500mongo.autoConnectRetry=truemongo.socketKeepAlive=true#Socket超时时间mongo.socketTimeout=1500mongo.slaveOk=true

编写Controller、Service、Dao相关.这里我们测试以下Spring-data-mong中对Collection的实现机制. 我们创建不同的实体类型Member、Article

然后编写对应的Service、Dao实现.这里我们侧重点持久层实现

持久层的操作实现

ArticleDao

package com.pudp.dao;import org.springframework.stereotype.Repository;import com.pudp.base.MongoGenDao;import com.pudp.model.Article;/** * description: * * @author <a href='mailto:[e-mail]'> Cn.��若年 (En.dennisit)</a> Copy Right since 2013-10-16  * * com.pudp.dao.ArticleDao.java * */@Repositorypublic class ArticleDao extends MongoGenDao<Article>{        /**     * 实现钩子方法,返回反射的类型     * @author <a href='mailto:[e-mail]'>Cn.苏若年(En.dennisit)</a> Copy Right since 2013-10-13      *                     * @return     */    @Override    protected Class<Article> getEntityClass() {        return Article.class;    }}

MemberDao

package com.pudp.dao;import org.springframework.stereotype.Repository;import com.pudp.base.MongoGenDao;import com.pudp.model.Member;/** * description: * * @author <a href='mailto:[e-mail]'> Cn.苏若年 (En.dennisit)</a> Copy Right since 2013-10-13  * * com.pudp.dao.MemberDao.java * */@Repositorypublic class MemberDao extends MongoGenDao<Member>{    /**     * 实现钩子方法,返回反射的类型     * @author <a href='mailto:[e-mail]'>Cn.苏若年(En.dennisit)</a> Copy Right since 2013-10-13      *                     * @return     */    @Override    protected Class<Member> getEntityClass() {        return Member.class;    }}

MongoGenDao中我们实现了对库中添加数据

package com.pudp.base;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.data.mongodb.core.MongoTemplate;/** * description: * * @author <a href='mailto:[e-mail]'> Cn.苏若年 (En.dennisit)</a> Copy Right since 2013-10-13  * * com.pudp.base.MongoGenDao.java * */public abstract class MongoGenDao<T> {    @Autowired    protected MongoTemplate mongoTemplate;        /**     * 保存一个对象     *     * @author <a href='mailto:[e-mail]'>Cn.苏若年(En.dennisit)</a> Copy Right since 2013-10-13 下午03:37:28     *                     * @param t     * @return     */    public void save(T t){        this.mongoTemplate.save(t);    }            /**     * 为属性自动注入bean服务     *     * @author <a href='mailto:[e-mail]'>Cn.pudp(En.dennisit)</a> Copy Right since 2013-10-13 下午03:21:23     *                     * @param mongoTemplate     */    public void setMongoTemplate(MongoTemplate mongoTemplate) {        this.mongoTemplate = mongoTemplate;    }    }

这里需要说明的是MongoTemplate对库的管理。

MongoTemplate对库Collection的管理

我们使用MongoTemplate操作持久层.这里如果我们没有指定CollectionName的话,会依实体类型的类名作为库中的集合名,当我们执行数据入库操作之后,从数据库中查看到如下信息.

当然,如果我们想自己定义数据库的Collection名的化,可以在持久层Dao中指定. 关于Mongodb的可以Mongodb相关的内容. 下一页介绍SpringMVC+ Mongodb 的CRUD + 分页实现.
