spring mongodb 配置

1、修改pom文件，加入

		<dependency>
			<groupId>org.mongodb</groupId>
			<artifactId>mongo-java-driver</artifactId>
			<version>3.0.3</version>
		</dependency>

2、修改applicationContext.xml，加入mongodb配置

<?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: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/tx
        http://www.springframework.org/schema/tx/spring-tx.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">
             
    <context:component-scan base-package="com.hangyu.hylbs" />
    <tx:annotation-driven transaction-manager="transactionManager"/>
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="hylbsDataSource" />
    </bean>
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="hylbsDataSource" />
    </bean>
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.hangyu.hylbs.mapper" />
    </bean>
     
    
    <mongo:mongo host="192.168.1.186" port="10000" />
    <mongo:db-factory dbname="DoctorLBS" mongo-ref="mongo" />
    <bean id="MongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate">
        <constructor-arg name="mongoDbFactory" ref="mongoDbFactory" />
    </bean>
</beans>

3、使用前注入，mongoTemplate

    @Autowired
    private MongoTemplate mongoTemplate;
 
    @Override
    public DBObject findOne(String collection, DBObject query, DBObject fields) {
        return mongoTemplate.getCollection(collection).findOne(query, fields);
    }
