使用Spring的@Autowired 实现DAO, Service, Controller三层的注入(转)
简述:
结合Spring和Hibernate进行开发
使用@Autowired实现依赖注入, 实现一个学生注册的功能,做一个技术原型
从DAO(Repository) -> Service -> Controller
目录结构:
使用Maven做本地包管理,

由于使用了Tomcat的数据源,所以还需要在Tomcat的Context.xml中添加数据库连接配置
context.xml(Tomcat server中文件,eclispe中在workspace中的server project中)
