MongoDB整合Spring 詳細講解(含代碼)

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!

首先建立application.xml設定檔

<?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> 

然後編寫操作mongodb的介面

/** * AbstractRepository.java * 著作權(C) 2012  * 建立: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>添加對象 * @author cuiran * @createDate 2012-12-12 11:41:30 */public void insert(Person person); /** *  *<b>function:</b>根據ID尋找對象 * @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);   }

再寫對應介面的實作類別：

/** * PersonRepository.java * 著作權(C) 2012  * 建立: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;}}

這裡也給出對應Person對象代碼

/** * Person.java * 著作權(C) 2012  * 建立: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+"]";       }   }

最後寫出我們的測試類別開始進行測試

/** * MongoTest.java * 著作權(C) 2012  * 建立: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("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尋找對象 * @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 stubMongoTest t=new MongoTest();t.start();}}

運行出現一下日誌，就沒什麼問題。

2012-12-12 16:23:59:DEBUG com.mongo.test.MongoTest - 開始啟動2012-12-12 16:23:59:INFO org.springframework.context.support.ClassPathXmlApplicationContext - Refreshing org.springframework.context.support.ClassPathXmlApplicationContext@253498: startup date [Wed Dec 12 16:23:59 CST 2012]; root of context hierarchy2012-12-12 16:23:59:INFO org.springframework.beans.factory.xml.XmlBeanDefinitionReader - Loading XML bean definitions from class path resource [applicationContext.xml]2012-12-12 16:24:00:INFO org.springframework.beans.factory.support.DefaultListableBeanFactory - Pre-instantiating singletons in org.springframework.beans.factory.support.DefaultListableBeanFactory@12a0f6c: defining beans [mongo,mongoTemplate,personRepository,org.springframework.context.annotation.internalConfigurationAnnotationProcessor,org.springframework.context.annotation.internalAutowiredAnnotationProcessor,org.springframework.context.annotation.internalRequiredAnnotationProcessor,org.springframework.context.annotation.internalCommonAnnotationProcessor]; root of factory hierarchy2012-12-12 16:24:00:DEBUG com.mongo.test.MongoTest - Person[id=50c83cb552c2ceb0463177d6,name=cuiran,age=27]
