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
<?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>
然后编写操作mongodb的接口
/** * 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); }
再写对应接口的实现类：
/** * 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() */@Overridepublic List<Person> findAll() {// TODO Auto-generated method stubreturn getMongoTemplate().find(new Query(), Person.class); }/* (non-Javadoc) * @see com.mongo.dao.AbstractRepository#findAndModify(java.lang.String) */@Overridepublic 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) */@Overridepublic 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) */@Overridepublic 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) */@Overridepublic void insert(Person person) {// TODO Auto-generated method stubgetMongoTemplate().insert(person); }/* (non-Javadoc) * @see com.mongo.dao.AbstractRepository#removeAll() */@Overridepublic void removeAll() {// TODO Auto-generated method stubList<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) */@Overridepublic void removeOne(String id) {// TODO Auto-generated method stubCriteria 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;}}这里也给出对应Person对象代码
/** * 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+"]"; } }最后写出我们的测试类开始进行测试
/** * MongoTest.java * 版权所有(C) 2012 * 创建: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 log = LogFactory.getLog(MongoTest.class.getName());private AbstractRepository pr=null;/** * *<b>function:</b> * @author cuiran * @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 * @author cuiran * @createDate 2012-12-12 16:11:01 */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 * @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>查询所有 * @author cuiran * @createDate 2012-12-12 16:08:54 */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 * @author cuiran * @createDate 2012-12-12 16:11:37 */public void start(){init();//insert();//listAll();findOne();}/** *<b>function:</b>main函数 * @author cuiran * @createDate 2012-12-12 11:54:30 */public static void main(String[] args) {// TODO Auto-generated method stubMongoTest t=new MongoTest();t.start();}}
运行出现一下日志，就没什么问题。

由于这些程序只是作为测试使用，对出现的问题， 欢迎留言咨询。谢谢大家。
