spring整合mongodb集群和单机连接配置

单机连接：

<mongo:mongo-client host="192.168.1.201" port="27017"> <mongo:client-options write-concern="NORMAL" /> </mongo:mongo-client>

集群连接：(mongo.replica=192.168.1.201：27017,192.168.1.202：27017,192.168.1.203：27017)

  <mongo:mongo-client id="mongo" replica-set="${mongo.replica}">
	<mongo:client-options write-concern="NORMAL" />
</mongo:mongo-client>
