学习使用spring data连接mongodb replset
1、分别在两个命令窗口中以replset方式启动两个mongodb进程

D:\mongodb\bin>mongod.exe --dbpath=d:\mongodata\data0 --port=10001 --replSet rcw
/127.0.0.1:20001

D:\mongodb\bin>mongod.exe --dbpath=d:\mongodata\data1 --port=20001 --replSet rcw
/127.0.0.1:10001

2、连接到任何一个mongodb实例，初始话replset

mongo 127.0.0.1:10001/admin

> db.runCommand({"replSetInitiate":{
... "_id":"rcw",
... "members":[{
... "_id":1,
... "host":"127.0.0.1:10001"
... },
... {
... "_id":2,
... "host":"127.0.0.1:20001"
... }
... ]
... }})

3、再加入一个仲裁服务器

D:\mongodb\bin>mongod.exe --dbpath=d:\mongodata\data1 --port 30001 replSet 127.0.0.1:10001
mongo 127.0.0.1:10001/admin
>rs.addArb({"127.0.0.1:30001"})

4、下载spring，spring-data-common即（spring-data-core）以及spring-mongodb，注意这里的data-common要下载1.2.1的，才能和mongodb1.0.1配合，最新版会出错，建立一个spring mvc项目，配置文件
web.xml
