寫這篇文章也做了下思考，首先是本人技術欠佳。但就是喜歡研究一些東西。因為在此之前有很多的朋友已經寫過類似的，很多我也看過，但是講解的不夠深入。對有些朋友提出的問題不能給出答案。在這裡，我根據我目前的能力對其進行整理。並最終運行成功。
在測試過程中出現過一下問題：
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。特別是第二個錯誤我看有些解決時候提到了jpa，但是我這裡沒有使用jpa後來我是把spring-data-commons的包替換了個版本就不出現了。
我先說下我的開發環境：
myeclipse 6.5
MongoDB 2.0.8
spring 3.0.4
最後就是下面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) 這裡我就給出我所採用的版本
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
然後就開始我們開發之旅吧!
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"> <constructor-arg ref="mongo"/> <constructor-arg name="databaseName" value="db"/> <constructor-arg name="defaultCollectionName" value="person" /> </bean> <bean id="personRepository"> <property name="mongoTemplate" ref="mongoTemplate"></property> </bean> <context:annotation-config /> </beans>
然後編寫操作mongodb的接口
/** * AbstractRepository.java */ package com.mongo.dao; import java.util.List; import com.mongo.bean.Person; /** * TODO * @author cuiran * @version TODO */ public interface AbstractRepository { /** * *<b>function:</b>添加對象* @author cuiran * @createDate 2012-12-12 11:41:30 */ public void insert(Person person); /** * *<b>function:</b>根據ID查找對象* @author cuiran * @createDate 2012-12-12 11:41:41 */ public Person findOne(String id); /** * *<b>function:</b>查詢所有* @author cuiran * @createDate 2012-12-12 16:26:06 */ public List<Person> findAll(); public List<Person> findByRegex(String regex); /** * *<b>function:</b>刪除指定的ID對象* @author cuiran * @createDate 2012-12-12 16:26:16 */ public void removeOne(String id); /** * *<b>function:</b>刪除所有* @author cuiran * @createDate 2012-12-12 16:25:40 */ public void removeAll(); /** * 通過ID找到並修改*<b>function:</b> * @author cuiran * @createDate 2012-12-12 16:25:51 */ public void findAndModify(String id); }再寫對應接口的實現類：
/** * PersonRepository.java */ 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; } }這裡也給出對應Person對象代碼
/** * Person.java */ 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+"]"; } }最後寫出我們的測試類開始進行測試
/** * MongoTest.java */ 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("開始啟動"); 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); } /** * *<b>function:</b>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()); } } /** * *<b>function:</b>測試方法* @author cuiran * @createDate 2012-12-12 16:11:37 */ public void start(){ init(); //insert(); //listAll(); findOne(); } /** *<b>function:</b>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(); } }運行出現一下日誌，就沒什麼問題。
