1.spring.xml文件配置

二、 基础DaoImpl实现类需要加的注解
public class DaoImpl {
@Resource
private JdbcTemplate jdbcTemplate;
/***下面是你的的sql基本操作方法**/
}
三、Action需要加的注解
@Controller
public class AliPayAction extends BaseAction{
@Resource
private IndexService indexService;//你的业务接口
/***下面是你的的action基本操作方法**/
}
四、接口的实现类需要加的注解
@Service("indexService")
public class IndexServiceImpl implements IndexService {
@Resource
private IndexDao indexDao;
/***下面是你的的业务实现方法**/
}
五、dao实现类的注入需要加的注解
@Service("indexDao")
public class IndexDaoImpl extends DaoImpl implements IndexDao {
/***下面是你的的业务实现方法**/
}
