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。因爲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。在這裏,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,但是我這裏沒有使用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) 這裏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
下載版本分別爲:
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
- <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>
然後編寫操作mongodb的接口
- <span style="font-size:18px;color:#3366ff;">/**
- * 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 {
- /**
- *
- *<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);
- }
- </span>
再寫對應接口的實現類:
- <span style="font-size:18px;color:#3366ff;">/**
- * 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;
- }
- }
- </span>
這裏也給出對應Person對象代碼
- <span style="font-size:18px;color:#3366ff;">/**
- * 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

- */
- 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;
- }
- /**

- */
- 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>
最後寫出我們的測試類開始進行測試
- <span style="font-size:18px;color:#3366ff;">/**

- /**

- public class MongoTest {
- private static Log log = LogFactory.getLog(MongoTest.class.getName());
- private AbstractRepository pr=null;
- /**

- public void init(){
- log.debug("開始啓動");

- }
- /**

- pr.insert(p);

- }
- /**

- public void findOne(){

- Person p= pr.findOne(id);
- log.debug(p);
- }
- /**

- 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

- public void start(){
- init();
- //insert();
- //listAll();
- findOne();
- }
- /**
- *<b>function:</b>main函數

- public static void main(String[] args) {
- // TODO Auto-generated method stub
- MongoTest t=new MongoTest();
- t.start();
- }
- }
- </span>
運行出現一下日誌,就沒什麼問題。
- <span style="font-size:18px;color:#3366ff;">2012-12-12 16:23:59:DEBUG com.mongo.test.MongoTest - 開始啓動
