Spring4分別整合mongo2.X和3.0

1.pom文件添加：

<dependency>
    <groupId>org.mongodb</groupId>
     <artifactId>mongo-java-driver</artifactId>
     <version>2.14.2</version>
</dependency>
        
<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-mongodb</artifactId>
    <version>1.7.2.RELEASE</version>
</dependency>

 

 

2.Spring配置文件的頭信息，其中只需關注mongo的三行就行：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc" 
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:tx="http://www.springframework.org/schema/tx"
    
    xmlns:mongo="http://www.springframework.org/schema/data/mongo"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.xsd
        
        http://www.springframework.org/schema/data/mongo 
        http://www.springframework.org/schema/data/mongo/spring-mongo.xsd
        http://www.springframework.org/schema/aop 
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        ">


　　　　 <mongo:mongo-client host="172.16.10.247" port="27017" id="mongo">  
          <mongo:client-options write-concern="SAFE"/>  
    　　</mongo:mongo-client>  
      
    　　<mongo:db-factory  id="mongoDbFactory" dbname="db_mongo" mongo-ref="mongo" />  //注釋，這句為了說明有賬號密碼而已，實際項目中沒有這句<mongo:db-factory dbname="db_mongo" mongo-ref="mongo" username="qqw_reward" password="Reward_New001"/>  

    　　<bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">  
      　　<constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />  
    　　</bean> 
</beans>

            

 

 

3.DAO層代碼：

package com.companyname.publicbase.dao;

import java.util.List;

import org.springframework.data.mongodb.core.query.Query;
import org.springframework.data.mongodb.core.query.Update;

public interface BaseMongoDao {
    
    public <T> List<T> find(Class<T> clazz); 
  
    public <T> T findOne(Query query, Class<T> clazz);
    
    public <T> void update(Query query, Update update, Class<T> T);
    
    //批量更新
    public <T> void updatemulti(Query query, Update update, Class<T> clazz); 
   
    public <T> void save(T entity);
  
    public <T> T findById(String id, Class<T> clazz);
  
      
    public <T> long count(Query query, Class<T> clazz);
      
    public <T> void remove(Query query, Class<T> clazz);
}

 

4.DAO實現類的代碼：

package com.companyname.publicbase.dao.impl;


import java.util.List;

import javax.annotation.Resource;

import org.springframework.data.mongodb.core.MongoTemplate;
import org.springframework.data.mongodb.core.query.Query;
import org.springframework.stereotype.Repository;
import org.springframework.transaction.annotation.Transactional;


@Repository
@Transactional(rollbackFor=Exception.class) 
public class BaseMongoDaoImpl<T>{  
    
    
    
    /*@Resource
    MongoTemplate mongoTemplate;
    public List<T> find(Query query, Class<T> clazz) {  
        return (List<T>) mongoTemplate.find(query, clazz);  
    }*/
    
    @Resource
    private MongoTemplate mongoTemplate;
    public List<T> find(Query query, Class<T> clazz) {  
        System.out.println(mongoTemplate);
        return (List<T>) mongoTemplate.find(query, clazz);  
    } 
      
     /** 
     * spring mongodb　集成操作類　 
     */  
    /*@Autowired private MongoTemplate mongoTemplate;  
    
    public List<T> find(Query query, Class<T> clazz) {  
        return (List<T>) mongoTemplate.find(query, clazz);  
    } */
  
    /*public T findOne(Query query, Class<T> clazz) {  
        return (T) mongoTemplate.findOne(query, clazz);  
    } 
  
    public void update(Query query, Update update, Class<T> clazz) {  
        mongoTemplate.findAndModify(query, update, clazz);  
    } 
    
    //批量更新
    public void updatemulti(Query query, Update update, Class<T> clazz) {  
        mongoTemplate.updateMulti(query, update, clazz);  
    } 
   
    public void save(T entity) {  
        mongoTemplate.insert(entity);  
    }  
  
    public T findById(String id, Class<T> clazz) {  
        return (T) mongoTemplate.findById(id, clazz);  
    }  
  
      
    public long count(Query query, Class<T> clazz){  
        return mongoTemplate.count(query, clazz);  
    }  
      
    public void remove(Query query, Class<T> clazz){  
         mongoTemplate.remove(query,  clazz);  
    } 
*/
} 

 

這樣Spring4整合mongo3.X就結束了，如果報這個異常：NoClassDefFoundError: org/springframework/objenesis/ObjenesisStd，

就說明你用的不是spring4.x，到此恭喜你已經整合完畢了。

-------------------------------------------------------------------------------------------------------------------------------------------------------------------

 

 

 

下面就是整合mongo2.x的內容了，這個spring3.2起碼是沒有問題的，來！下面開始整理:

1.pom文件：

   <dependency>
      <groupId>org.mongodb</groupId>
      <artifactId>mongo-java-driver</artifactId>
      <version>2.12.4</version>
    </dependency>

    <dependency>
      <groupId>org.springframework.data</groupId>
      <artifactId>spring-data-mongodb</artifactId>
      <version>1.6.1.RELEASE</version>
    </dependency>

 

2.Spring文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:mvc="http://www.springframework.org/schema/mvc" 
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop" 
    xmlns:tx="http://www.springframework.org/schema/tx"
    
    xmlns:mongo="http://www.springframework.org/schema/data/mongo"
    xsi:schemaLocation="
        http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/mvc
        http://www.springframework.org/schema/mvc/spring-mvc.xsd
        http://www.springframework.org/schema/context
        http://www.springframework.org/schema/context/spring-context.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/aop 
        http://www.springframework.org/schema/aop/spring-aop.xsd
        http://www.springframework.org/schema/tx
        http://www.springframework.org/schema/tx/spring-tx.xsd
        ">

　<mongo:mongo host="172.16.10.247" port="27017"/>
  <mongo:db-factory dbname="db_mongo" mongo-ref="mongo" username="qqw_reward" password="Reward_New001"/>

  <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
    <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
  </bean>
</beans>

 

3.java調用就跟上面一樣了，dao和實現類都是一樣的，就這樣兩套都整理完了，有什么要完善的再回來改，之前測試過是沒有問題的，百分百能跑，
