SPRINGMVC Integrated MONGODB Development Architecture Building

System environment:

Operating system: Windows XP

Database: mongodb2.0.6

Driver Package: Spring3.1.2 + mongodb2.7.3 + spring-data-mongodb1.0.1

Note: For XP system users, when performing Mongod.exe installation MongoDB, can not locate the program input point InterlockedCompareExchange64 on the dynamic link library KERNEL32.dll, This is because XP is no longer supported by the latest development Branch. That is, your MongoDB installation package does not support XP. V2.0.6 is the latest and last new version to support XP. So I use database for 2.0.6

Write controller, Service, DAO related. Here we test the implementation mechanism for collection in the following Spring-data-mong. We create different entity types Member, article

Then write the corresponding service, DAO implementation. Here we focus on persistence layer implementation

Operation implementation of the persistence layer

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:[email protected] ' > Cn. Sujonin (En.dennisit) < /a> Copy Right Since 2013-10-16  * * Com.pudp.dao.ArticleDao.java * */@Repositorypublic class Articledao extends Mon gogendao<article>{        /**     * Implements the hook method, returns the type of reflection     * @author <a href= ' mailto:[email protected] ' >CN. Sujonin (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:[email protected] ' > Cn. Sujonin (en.dennisit) </ A> Copy Right Since 2013-10-13  * * Com.pudp.dao.MemberDao.java * */@Repositorypublic class Memberdao extends Mongog endao<member>{    /**     * Implements the hook method, returns the type of reflection     * @author <a href= ' mailto:[email protected] ' >CN. Sujonin ( en.dennisit) </a> Copy right since 2013-10-13      *                     * @return */    @Override    protected class< Member> Getentityclass () {        return member.class;    }}

In Mongogendao we implemented the addition of data to the library.

Package Com.pudp.base;import Org.springframework.beans.factory.annotation.autowired;import org.springframework.data.mongodb.core.mongotemplate;/** * Description: * * @author <a href= ' mailto:[email  Protected] ' > Cn. Sujonin (en.dennisit) </a> Copy Right Since 2013-10-13 * * Com.pudp.base.MongoGenDao.java * */public        Abstract class Mongogendao<t> {@Autowired protected mongotemplate mongotemplate; /** * Save an object * * @author <a href= ' mailto:[email protected] ' &GT;CN. Sujonin (en.dennisit) </a> Copy righ T since 2013-10-13 pm 03:37:28 * * @param t * @return */public void Save (T t) {T    His.mongoTemplate.save (t); }/** * Automatically injects bean service for attributes * * @author <a href= ' mailto:[email protected] ' >cn.pudp (en.dennisit ) </a> Copy Right since 2013-10-13 pm 03:21:23 * * @param mongotemplate */public void       Setmongotemplate (Mongotemplate mongotemplate) { This.mongotemplate = mongotemplate; }    }

What needs to be explained here is the Mongotemplate management of the library.

Mongotemplate the management of library collection

We use the mongotemplate to operate the persistence layer. If we do not specify CollectionName, the name of the collection in the library will be based on the class names of the entity type, and when we perform the data inbound operation, we see the following information from the database.

Of course, if we want to define the collection name of the database, we can specify it in the Persistence layer DAO. About MongoDB can be mongodb related content. The following will introduce the CRUD + paging implementation of springmvc+ Mongodb.
