解释：
　　test是测试路径，system与manage是模块名(这本来是package的路径，为了简化，我把前面的包名删除了)，每个模块中有一个spring的配置文件(我的spring配置文件的命名策略是test+模块名+Context)，一个模块级别测试基类(主要是载入spring配置文件，每个该模块的单元测试类都继承该类)，然后是分层路径，这里是DAO和service层，包括所有的DAO与service单元测试类，我们还有一个总的spring配置文件testApplicationContext.xml。再多的解释，也不如代码明显，下面是部分示例代码
testApplicationContext.xml
