spring注入时采用注解的方法

架构采用spring mvc + spring + hibernate 的方式来做，spring和hibernate均采用注解的方式，先总结spring的注解方式

Controller层

@Controller
public class LoginController {

	public LoginService loginService;
	
	public UserService userService;
	
	@Resource(name="loginService")
	public void setLoginService(LoginService loginService) {
		this.loginService = loginService;
	}
	
	@Resource(name="userService")
	public void setUserService(UserService userService) {
		this.userService = userService;
	}

Service层的接口不加注解，在实现类上加注解

@Service(value="loginService")
public class LoginServiceImpl implements LoginService{
	
	public LoginDao loginDao;

	@Resource(name="loginDao")
	public void setLoginDao(LoginDao loginDao) {
		this.loginDao = loginDao;
	}

Dao层的接口不加注解，在实现类上加注解，同时把HibernateTemplate也加进来

@Repository(value="loginDao")
public class LoginDaoImpl implements LoginDao{

	public HibernateTemplate hibernateTemplate;
	
	public HibernateTemplate getHibernateTemplate() {
		return hibernateTemplate;
	}
    
	@Resource
	public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
		this.hibernateTemplate = hibernateTemplate;
	}
