最后就是下面2個(這兩個版本不對就容易出現各種各樣的，雜七雜八的問題) 這里我就給出我所采用的版本

spring-data-document

spring-data-commons

有所改變所有版本必須要對應好下面是jar下載地址
http://www.springsource.org/spring-data/mongodb
http://www.springsource.org/spring-data/commons

下載版本分別為：

spring-data-commons-dist-1.4.0.M1

spring-data-document-1.0.0.M2.zip
下面給出我工程的圖片

然后就開始我們開發之旅吧!

首先新建application.xml配置文件

[html] view plain copy

<?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>

然后編寫操作mongodb的接口

[java] view plain copy

/**
* AbstractRepository.java
* 版權所有(C) 2012
* 創建: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 {
/**
*
*function:添加對象
* @author cuiran
* @createDate 2012-12-12 11:41:30
*/
public void insert(Person person);
/**
*
*function:根據ID查找對象
* @author cuiran
* @createDate 2012-12-12 11:41:41
*/
public Person findOne(String id);
/**
*
*function:查詢所有
* @author cuiran
* @createDate 2012-12-12 16:26:06
*/
public List<Person> findAll();
public List<Person> findByRegex(String regex);
/**
*
*function:刪除指定的ID對象
* @author cuiran
* @createDate 2012-12-12 16:26:16
*/
public void removeOne(String id);
/**
*
*function:刪除所有
* @author cuiran
* @createDate 2012-12-12 16:25:40
*/
public void removeAll();
/**
* 通過ID找到并修改
*function:
* @author cuiran
* @createDate 2012-12-12 16:25:51
*/
public void findAndModify(String id);
}

再寫對應接口的實現類：

[java] view plain copy

/**
* PersonRepository.java
* 版權所有(C) 2012
* 創建: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;
}
}

這里也給出對應Person對象代碼

[java] view plain copy

/**
* Person.java
* 版權所有(C) 2012
* 創建: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+"]";
}
}

最后寫出我們的測試類開始進行測試

[java] view plain copy

/**
* MongoTest.java
* 版權所有(C) 2012
* 創建: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;
/**
*
*function:
* @author cuiran
* @createDate 2012-12-12 16:08:02
*/
public void init(){
log.debug("開始啟動");
ApplicationContext ctx = new ClassPathXmlApplicationContext("applicationContext.xml");
pr= (PersonRepository)ctx.getBean("personRepository");
}
/**
*
*function: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");
}
/**
*
*function:根據輸入的ID查找對象
* @author cuiran
* @createDate 2012-12-12 16:24:10
*/
public void findOne(){
String id="50c83cb552c2ceb0463177d6";
Person p= pr.findOne(id);
log.debug(p);
}
/**
*
*function:查詢所有
* @author cuiran
* @createDate 2012-12-12 16:08:54
*/
public void listAll(){
List<Person> list=pr.findAll();
log.debug("查詢結果如下:");
for (Person p:list){
log.debug(p.toString());
}
}
/**
*
*function:測試方法
* @author cuiran
* @createDate 2012-12-12 16:11:37
*/
public void start(){
init();
//insert();
//listAll();
findOne();
}
/**
*function:main函數
* @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();
}
}

運行出現一下日志，就沒什么問題。

[java] view plain copy

由于這些程序只是作為測試使用，對出現的問題，歡迎留言咨詢。謝謝大家。

在此附上demo源碼歡迎朋友下載學習
