最近研究了一下MongoDB的使用，总结一下如何利用SpringMVC + MongoDB + Maven 搭建项目架构。
系统环境：
操作系统：Windows 7
数据库：MongoDB 3.2.0
驱动包：spring 3.2.11 + spring-data-mongodb 1.2.0
项目结构：

public User getUser(){
Date now = new Date();
User user = new User();
user.setTelephone("12322241");
user.setEmail("[email protected]");
user.setNickname("七彩狼222");
user.setPassword("123456.");

user.setStatus(Constants.STATUS_BLOCK);
user.setCreatedTime(now);
user.setUpdatedTime(now);
user.setLastLoginTime(now);
return user;
}注：以上为测试的被插入的一条记录
