    <bean id="mongoDao" class="com.tofba.dao.common.base.MongoDao">

    </bean>
</beans>

MongoDB3.x版本Maven配置

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-mongodb</artifactId>
    <version>1.8.0.RELEASE</version>
</dependency>

1.8.0版本自动依赖了mongo-java-driver，spring-data-commons无需导入其他Jar包

xml配置,配置如下：注意需要将spring组件升级到4.1.8以上要不然会报错哦！！！！！！！！！！！！！！！！！！！！！
