The first step to configure the maven. I currently used here is the latest

& lt; ! - directing a start - & gt;
& lt; Dependency>
& lt; GroupId> Org. Mongodb
& lt; ArtifactId> Mongo Java - driver
& lt; Version> 3.9.1 & lt;/version>
& lt;/dependency>
& lt; Dependency>
& lt; GroupId> Org. Springframework. Data
& lt; ArtifactId> Spring - data - mongodb
& lt; Version> 1.7.1. RELEASE
& lt;/dependency>
& lt; ! - directing end - & gt;
The second step is to create mongo. The properties, of which the

# DB name
Mongo. Dbname=erp_company
# username
Mongo. Username=HSJG
# password
Mongo. Password=1
# host
Mongo. Host=127.0.0.1
# port
Mongo. Port=27017
# xiancheng zui da zu se shu
Mongo. ConnectionsPerHost=8
# xiancheng dui lie shu
Mongo. ThreadsAllowedToBlockForConnectionMultiplier=4
# connectTimeout ms
Mongo. ConnectTimeout=1500
# maxWaitTime
Mongo. MaxWaitTime=1500
# autoConnect
Mongo. AutoConnectRetry=true
# socketKeepAlive
Mongo. SocketKeepAlive=true
# socketTimeout
Mongo. SocketTimeout=1500
# du xie fen li
Mongo. SlaveOk=true
The third step to create the spring - mongo. XML
