Share the simple code that HA I tested the MongoDB database

In the original: share my simple code to test the MONGODB database

Distributed file storage System, MONGODB deployment installation can be referenced as follows:

Http://www.cnblogs.com/mecity/archive/2011/06/11/2078527.html

The demo enables the data to be read row by line from the TXT file and stored in the MongoDB database.

Refer to other demo codes

This is a simple case source based on spring, Hibernate, Spring Data, Akka, Twitter Bootstrap, Apache Tiles, jquery.
