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
- <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>
然后编写操作mongodb的接口
- <span style="font-size:18px;color:#3366ff;">/**
- * 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);
-
-
- }
- </span>
再写对应接口的实现类:
- <span style="font-size:18px;color:#3366ff;">/**
- * 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()
- */
- @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>
这里也给出对应Person对象代码
- <span style="font-size:18px;color:#3366ff;">/**
- * 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+"]";
- }
-
-
- }
- </span>
最后写出我们的测试类开始进行测试
运行出现一下日志,就没什么问题。
- <span style="font-size:18px;color:#3366ff;">2012-12-12 16:23:59:DEBUG com.mongo.test.MongoTest - 开始启动

- </span>
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。
