MongoDB Integration Spring Detail (with code)

Write this article also did the next thinking, first of all, I am poor technology. But just like to study something. Because before this many friends have written similar, a lot of I have read, but the explanation is not deep enough. There is no answer to the questions raised by some friends. Here, I organize it according to my current ability. And finally run successfully.

A problem occurred during the test:

1, Org/springframework/data/mapping/context/mappingcontextaware

2, Src-resolve:cannot resolve the name ' Repository:repository ' to A (n) ' type definition '

All of these are due to a version mismatch. Especially the second one. I see some sort of solution for JPA, but I'm not using JPA here. Later I did not show up to replace the Spring-data-commons package with a version.

Let me start by saying my development environment:

MyEclipse 6.5

MongoDB 2.0.8

Spring 3.0.4

The last is the following 2 (these two versions are not easy to appear in a variety of, assorted problems) Here I'll give the version I'm using.

Spring-data-document

Spring-data-commons

Change all versions must correspond well below is the jar download address
Http://www.springsource.org/spring-data/mongodb
Http://www.springsource.org/spring-data/commons

The download versions are:

Spring-data-commons-dist-1.4.0.m1

Spring-data-document-1.0.0.m2.zip
Here's a picture of my project.

Then start our development tour!

First new application.xml configuration file

<?xml version= "1.0" encoding= "UTF-8"?> <beans xmlns= "Http://www.springframework.org/schema/beans" xml Ns:xsi= "Http://www.w3.org/2001/XMLSchema-instance" xmlns:context= "Http://www.springframework.org/schema/contex T "xmlns:mongo=" Http://www.springframework.org/schema/data/mongo "xsi:schemalocation=" http://www.s   
          Pringframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd Http://www.springframework.org/schema/data/mongo Http://www.springframework.org/schema/data/mongo/spri Ng-mongo-1.0.xsd Http://www.springframework.org/schema/beans Http://www.springframework.org/sche Ma/beans/spring-beans-3.0.xsd "> <mongo:mongo host=" 192.168.0.138 "port=" 27017 "/> <bean i D= "Mongotemplate" class= "org.springframework.data.document.mongodb.MongoTemplate" > <constructor-arg ref= "mo NGO "/> <conStructor-arg name= "DatabaseName" value= "db"/> <constructor-arg "name=" defaultcollectionname "person"/   
        > </bean> <bean id= "personrepository" class= "Com.mongo.dao.impl.PersonRepository" > <property name= "Mongotemplate" ref= "mongotemplate" ></property> </bean> <cont 
	 Ext:annotation-config/> </beans>

and then write an interface that operates MongoDB

/** * Abstractrepository.java * Copyright (C) 2012 * Create: Cuiran 2012-12-12 11:40:40/package Com.mongo.dao;

Import java.util.List;

Import Com.mongo.bean.Person; /** * TODO * @author Cuiran * @version todo/public interface Abstractrepository {/** * *<b>function: 
	
	</b> Add Object * @author Cuiran * @createDate 2012-12-12 11:41:30/public void inserts (person); /** * *<b>function:</b> find objects by ID * @author Cuiran * @createDate 2012-12-12 11:41:41/Public Pe   
    Rson FindOne (String ID);
    /** * *<b>function:</b> Inquiry ALL * @author Cuiran * @createDate 2012-12-12 16:26:06/   
    
    Public list<person> findall ();
    Public list<person> Findbyregex (String regex);
     /** * *<b>function:</b> Delete the specified ID object * @author cuiran * @createDate 2012-12-12 16:26:16   
    */public void Removeone (String id); /** * *<b>function:</b> Delete all * @author Cuiran * @createDate 2012-12-12 16:25:40/public void RemoveAll ();
     /** * found and modified by ID *<b>function:</b> * @author cuiran * @createDate 2012-12-12 16:25:51   

	
*/public void findandmodify (String id);
 }

to write the implementation class for the corresponding interface:

/** * Personrepository.java * Copyright (C) 2012 * Create: Cuiran 2012-12-12 11:42:51/package Com.mongo.dao.impl;
Import java.util.List;

Import Java.util.regex.Pattern;
Import Org.springframework.data.document.mongodb.MongoTemplate;
Import Org.springframework.data.document.mongodb.query.Criteria;
Import Org.springframework.data.document.mongodb.query.Query;
Import Org.springframework.data.document.mongodb.query.Update;
Import Com.mongo.bean.Person;

Import Com.mongo.dao.AbstractRepository; /** * TODO * @author Cuiran * @version todo/public class Personrepository implements Abstractrepository {Priva   

	Te Mongotemplate mongotemplate; /* (non-javadoc) * @see com.mongo.dao.abstractrepository#findall () * * * @Override public list<person> findall ()   

	{//TODO auto-generated Method stub return Getmongotemplate ().

	      ex,pattern.case_insensitive);   
	        The Criteria criteria = new criteria ("name"). Regex (Pattern.tostring ());   

	Return Getmongotemplate (). Find (new Query (criteria), person.class); }/* (non-javadoc) * @see com.mongo.dao.abstractrepository#findone (java.lang.String) * * * @Override public person fi Ndone (String ID) {//TODO auto-generated Method stub return Getmongotemplate ().

	). is (ID), person.class); }/* (non-javadoc) * @see com.mongo.dao.AbStractrepository#insert (Com.mongo.bean.Person) */@Override public void Insert (person) {//TODO Auto-generat   
	Ed method Stub Getmongotemplate (). Insert (person);  }/* (non-javadoc) * @see com.mongo.dao.abstractrepository#removeall () * * * @Override public void RemoveAll () {//   
        TODO auto-generated Method Stub list<person> List = This.findall ();   
            if (list!= null) {for (person person:list) {getmongotemplate (). remove (person); }}/* (non-javadoc) * @see com.mongo.dao.abstractrepository#removeone (java.lang.String) * /@Override public void Removeone (String ID) {//TODO auto-generated Method Stub criteria = Criteria.where   
        ("id"). in (ID);   
             if (criteria = = NULL) {query query = new Query (criteria); If query!= null && getmongotemplate (). FindOne (query, person.class)!= null) getmongotemplate ( ). Remove (gEtmongotemplate (). FindOne (query, Person.class));
	}/** * @return the mongotemplate */public mongotemplate getmongotemplate () {return mongotemplate; /** * @param mongotemplate the mongotemplate to set */public void setmongotemplate (Mongotemplate mongotemplate)
	{this.mongotemplate = mongotemplate;
 }

}

The corresponding Person object code is also given here

/** * Person.java * Copyright (C) 2012 * Create: Cuiran 2012-12-12 11:37:16/package Com.mongo.bean;

Import java.io.Serializable; /** * TODO * @author Cuiran * @version todo/public class person implements Serializable {/** * * * Private
	
	Static final Long serialversionuid = 3617931430808763429L;   
    Private String ID;   
    private String name;
	private int age;
	Public person () {super ();
		Public person (string ID, string name, int age) {super ();
		This.id = ID;
		THIS.name = name;
	This.age = age;
	}/** * @return the ID */public String getId () {return id;
	/** * @param id The ID to set */public void setId (String id) {this.id = ID;
	}/** * @return the name */public String GetName () {return name;
	}/** * @param name the name to set */public void SetName (String name) {this.name = name;
	/** * @return The Age/public int getage () {return age; /** * @param age of the age to set */public void Setage (int age) {this.age = age;
		}/** * * @param name * @param age/Public person (String name, int age) {super ();
		THIS.name = name;
	This.age = age;   
	    Public String toString () {return "person[id=" +id+ ", name=" +name+ ", age=" +age+ "]";
 }   


}

Finally write our test class to start testing

/** * Mongotest.java * Copyright (C) 2012 * Create: Cuiran 2012-12-12 11:54:30/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; /** * TODO * @author Cuiran * @version todo/public class Mongotest {private static log = Logfactory.getlog (M
	
	OngoTest.class.getName ());
	
	Private Abstractrepository Pr=null;
		 /** * *<b>function:</b> * @author Cuiran * @createDate 2012-12-12 16:08:02/public void init () {
		 Log.debug ("Start");
		  ApplicationContext CTX = new Classpathxmlapplicationcontext ("Applicationcontext.xml");
		 
		
		
	Pr= (personrepository) Ctx.getbean ("Personrepository"); }/** * *<b>function:</b> add
	 * @author Cuiran * @createDate 2012-12-12 16:11:01 */public void Insert () {person p=new person ("Cuiran", 27);
		 Pr.insert (P);
	Log.debug ("add success");  /** * *<b>function:</b> finds objects based on the ID entered * @author cuiran * @createDate 2012-12-12 16:24:10/Public
		void FindOne () {String id= "50c83cb552c2ceb0463177d6";
		Person p= pr.findone (ID);
	Log.debug (P); /** * *<b>function:</b> Query all * @author Cuiran * @createDate 2012-12-12 16:08:54/Public VO
		ID Listall () {list<person> list=pr.findall ();
		Log.debug ("Query results are as follows:");
		for (person p:list) {Log.debug (p.tostring ()); }/** * *<b>function:</b> test method * @author Cuiran * @createDate 2012-12-12 16:11:37 */PU
		
		Blic void Start () {init ();
		Insert ();
		
		Listall ();
	FindOne (); /** *<b>function:</b>main function * @author Cuiran * @createDate 2012-12-12 11:54:30/public static void Main (string[] args) {//TODO auto-generated Method Stub mongotest t=new mongotest ();
	T.start ();
 }

}

It's OK to run a log.
