springMVC集成mongodb

提示：文章写完后，目录可以自动生成，如何生成可参考右边的帮助文档

---

前言

提示：使用mongodb需要导入spring-data-mongodb-1.10.15.RELEASE.jar驱动，注意 这个驱动jar要根据spring的版本来决定版本，spring如果是4.x就导入1.x的，如果是5.x就导入2.x的。。

提示：以下是本篇文章正文内容，下面案例可供参考

1.导入jar包

2.新建一个xml

spring-mongodb.xml：

   <!--  配置mongodb的用户及密码 -->
   <!-- <bean id="userCredentials" class="com.redxun.core.mongodb.dao.UserCredentials">

   <!-- <mongo:db-factory dbname="${mongo.dbName}" username="${mongo.username}" password="${mongo.password}" mongo-ref="mongoClient" /> -->
   <!-- 声明mongoTemplate -->

        <constructor-arg ref="mongoDbFactory" />
        <constructor-arg ref="converter" />
    </bean>
 
</beans>

3.再导入到mvc项目中读取配置的配置中

4.配置连接

#mongodb.properties配置
mongo.hostport=192.168.0.102:27017
mongo.dbName=filedb
mongo.username=root
mongo.password=bdc123456
mongo.connectionsPerHost=8
mongo.threadsAllowedToBlockForConnectionMultiplier=4
#连接超时时间
mongo.connectTimeout=1000
#等待时间
mongo.maxWaitTime=1500
mongo.autoConnectRetry=true
mongo.socketKeepAlive=true
#Socket超时时间
mongo.socketTimeout=1500
mongo.slaveOk=true
