Maven模块与模块间的依赖
在Maven+Hibernate4注解0配置示例中创建用户操作数据库的模块，现在创建用户管理服务模块user-service。
user-service模块是要依赖user-dao模块的，怎么用maven来管理依赖呢？
1.在user-dao模块下,pom.xml中右键，选择maven install命令，将user-dao发布到本地仓库中；
2.在user-service模块下,pom.xml中添加对user-dao模块的依赖。Maven会将user-dao中依赖的Jar一同拷贝过来。
user-service模块包括：
1个用户操作服务接口类IUserService;
1个用户操作服务实现类UserService;
1个单元测试类TestUserSerivice。
IUserService中包含3个方法，分别为添加用户，根据用户名查找某个用户，以及列出所有的用户。
单元测试使用easymock来mock对象的预期行为。
