首先看看Mongodb的导出功能，在bin目录下有个mongoexport 用来实现导出功能，主要参数如下

写道

Options:
--help produce help message
-v [ --verbose ] be more verbose (include multiple times
for more verbosity e.g. -vvvvv)
--quiet silence all non error diagnostic
messages
--version print the program's version and exit
-h [ --host ] arg mongo host to connect to ( <set
name>/s1,s2 for sets)
--port arg server port. Can also use --host
hostname:port
--ipv6 enable IPv6 support (disabled by

参数说明：

-h:指明数据库宿主机的IP

-u:指明数据库的用户名

-p:指明数据库的密码

-d:指明数据库的名字

-c:指明collection的名字

-f:指明要导出那些列

-o:指明到要导出的文件名

-q:指明导出数据的过滤条件

例如：

D:\mongodb_64-2.6.4\bin>mongoexport.exe -d test_his -c empilog -u test -p test -
o empilog.dat
connected to: 127.0.0.1
exported 600 records

DIR查看写道

D:\mongodb_64-2.6.4\bin 的目录

接下来是导入mongoimport

写道

D:\mongodb_64-2.6.4\bin>mongoimport --help
Import CSV, TSV or JSON data into MongoDB.

When importing JSON documents, each document must be a separate line of the inp
t file.

Example:
mongoimport --host myhost --db my_cms --collection docs < mydocfile.json

Options:
--help produce help message
-v [ --verbose ] be more verbose (include multiple times
for more verbosity e.g. -vvvvv)
--quiet silence all non error diagnostic
messages
--version print the program's version and exit
-h [ --host ] arg mongo host to connect to ( <set
name>/s1,s2 for sets)
--port arg server port. Can also use --host
hostname:port
--ipv6 enable IPv6 support (disabled by
default)
-u [ --username ] arg username
-p [ --password ] arg password
--authenticationDatabase arg user source (defaults to dbname)

--jsonArray load a json array, not one item per
line. Currently limited to 16MB.
