MongoDB整合Spring 详细讲解(含代码)

写这篇文章也做了下思考，首先是本人技术欠佳。但就是喜欢研究一些东西。因为在此之前有很多的朋友已经写过类似的，很多我也看过，但是讲解的不够深入。对有些朋友提出的问题不能给出答案。在这里，我根据我目前的能力对其进行整理。并最终运行成功。

在测试过程中出现过一下问题：

1、org/springframework/data/mapping/context/MappingContextAware

2、src-resolve: Cannot resolve the name 'repository:repository' to a(n) 'type definition'

以上都是版本不匹配引起的。特别是第二个错误我看有些解决时候提到了jpa，但是我这里没有使用jpa后来我是把spring-data-commons的包替换了个版本就不出现了。

我先说下我的开发环境：

myeclipse 6.5

mongodb 2.0.8

spring 3.0.4 

最后就是下面2个(这两个版本不对就容易出现各种各样的，杂七杂八的问题) 这里我就给出我所采用的版本

spring-data-document

spring-data-commons

有所改变所有版本必须要对应好下面是jar下载地址 
http://www.springsource.org/spring-data/mongodb 
http://www.springsource.org/spring-data/commons

下载版本分别为：

spring-data-commons-dist-1.4.0.M1

spring-data-document-1.0.0.M2.zip
下面给出我工程的图片

 

然后就开始我们开发之旅吧!

首先新建application.xml配置文件

<span style="font-size:18px;color:#3366ff;"><?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xmlns:context="http://www.springframework.org/schema/context"
          xmlns:mongo="http://www.springframework.org/schema/data/mongo"
          xsi:schemaLocation="http://www.springframework.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/spring-mongo-1.0.xsd
          http://www.springframework.org/schema/beans
          http://www.springframework.org/schema/beans/spring-beans-3.0.xsd">

        <mongo:mongo host="192.168.0.138" port="27017"/>



       <bean id="mongoTemplate" class="org.springframework.data.document.mongodb.MongoTemplate">
        <constructor-arg ref="mongo"/>
        <constructor-arg name="databaseName" value="db"/>
        <constructor-arg name="defaultCollectionName" value="person" />
      </bean>

     <bean id="personRepository" class="com.mongo.dao.impl.PersonRepository">
        <property name="mongoTemplate" ref="mongoTemplate"></property>
    </bean>

     <context:annotation-config />

</beans>
    </span>

然后编写操作mongodb的接口

<span style="font-size:18px;color:#3366ff;">/**
 * AbstractRepository.java
 * 版权所有(C) 2012
 * 创建: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>添加对象
     * @author cuiran
     * @createDate 2012-12-12 11:41:30
     */
    public void insert(Person person);

    /**
     *
     *<b>function:</b>根据ID查找对象
     * @author cuiran
     * @createDate 2012-12-12 11:41:41
     */
    public Person findOne(String id);
    /**
     *
     *<b>function:</b>查询所有
     * @author cuiran
     * @createDate 2012-12-12 16:26:06
     */
    public List<Person> findAll();

    public List<Person> findByRegex(String regex);
    /**
     *
     *<b>function:</b>删除指定的ID对象
     * @author cuiran
     * @createDate 2012-12-12 16:26:16
     */
    public void removeOne(String id);
    /**
     *
     *<b>function:</b>删除所有
     * @author cuiran
     * @createDate 2012-12-12 16:25:40
     */
    public void removeAll();
    /**
     * 通过ID找到并修改
     *<b>function:</b>
     * @author cuiran
     * @createDate 2012-12-12 16:25:51
     */
    public void findAndModify(String id);


}
</span>

再写对应接口的实现类：

<span style="font-size:18px;color:#3366ff;">/**
 * PersonRepository.java
 * 版权所有(C) 2012
 * 创建: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 {

      private MongoTemplate mongoTemplate;

    /* (non-Javadoc)
     * @see com.mongo.dao.AbstractRepository#findAll()
     */
    @Override
    public List<Person> findAll() {
        // TODO Auto-generated method stub
        return getMongoTemplate().find(new Query(), Person.class);

    }

    /* (non-Javadoc)
     * @see com.mongo.dao.AbstractRepository#findAndModify(java.lang.String)
     */
    @Override
    public void findAndModify(String id) {
        // TODO Auto-generated method stub
        //new Query(Criteria.where("id").is(id)), new Update().inc("age", 3)

        getMongoTemplate().updateFirst(new Query(Criteria.where("id").is(id)), new Update().inc("age", 3));

    }

    /* (non-Javadoc)
     * @see com.mongo.dao.AbstractRepository#findByRegex(java.lang.String)
     */
    @Override
    public List<Person> findByRegex(String regex) {
        // TODO Auto-generated method stub
         Pattern pattern = Pattern.compile(regex,Pattern.CASE_INSENSITIVE);
          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 findOne(String id) {
        // TODO Auto-generated method stub
         return getMongoTemplate().findOne(new Query(Criteria.where("id").is(id)), Person.class);

    }

    /* (non-Javadoc)
     * @see com.mongo.dao.AbstractRepository#insert(com.mongo.bean.Person)
     */
    @Override
    public void insert(Person person) {
        // TODO Auto-generated 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 = 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;
    }

}
</span>

这里也给出对应Person对象代码

<span style="font-size:18px;color:#3366ff;">/**
 * Person.java
 * 版权所有(C) 2012
 * 创建: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 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+"]";
        }


}
</span>

最后写出我们的测试类开始进行测试

<span style="font-size:18px;color:#3366ff;">/**
 * MongoTest.java
 * 版权所有(C) 2012
 * 创建:cuiran 2012-12-12 11:54:30
 */
package com.mongo.test;

import com.mongo.dao.AbstractRepository;
import com.mongo.dao.impl.PersonRepository;



/**
 * TODO
 * @author cuiran
 * @version TODO
 */
public class MongoTest {

    private static Log log = LogFactory.getLog(MongoTest.class.getName());

    private  AbstractRepository pr=null;

    /**
     *
     *<b>function:</b>

     * @createDate 2012-12-12 16:08:02
     */
    public void init(){
         log.debug("开始启动");
         ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
          pr= (PersonRepository)ctx.getBean("personRepository");



    }
    /**

     *<b>function:</b>添加

    public void insert(){

        Person p=new Person("cuiran",27);
         pr.insert(p);
         log.debug("添加成功");
    }
    /**

     *<b>function:</b>根据输入的ID查找对象

     */
    public void findOne(){
        String id="50c83cb552c2ceb0463177d6";
        Person p= pr.findOne(id);
        log.debug(p);
    }


    /**

    public void listAll(){

        List<Person> list=pr.findAll();
        log.debug("查询结果如下:");
        for (Person p:list){
            log.debug(p.toString());
        }


    }

    /**
     *
     *<b>function:</b>测试方法

    public void start(){
        init();

        //insert();
        //listAll();

        findOne();
    }

    /**
     *<b>function:</b>main函数

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        MongoTest t=new MongoTest();
        t.start();
    }

}
</span>

运行出现一下日志，就没什么问题。

<span style="font-size:18px;color:#3366ff;">2012-12-12 16:23:59:DEBUG com.mongo.test.MongoTest - 开始启动
