spring注解中@component是什么意思

@Component("userManager")
public class UserManagerImpl implements UserManager {
	private UserDao userDao;

	public UserDao getUserDao() {
		return userDao;
	}

	@Resource
	public void setUserDao(UserDao userDao) {
		this.userDao = userDao;
	}

	/*
	 * (non-Javadoc)
	 * 
	 * @see
	 * com.wjs.registration.service.UserManager#exists(com.wjs.registration.
	 * model.Users)
	 */
	public boolean exists(Users u) {
		return userDao.checkUserExistsWithName(u.getUsername());
	}

	/*
	 * (non-Javadoc)
	 * 
	 * @see
	 * com.wjs.registration.service.UserManager#add(com.wjs.registration.model
	 * .Users)
	 */
	public void add(Users u) {
		userDao.save(u);
	}
}

在持久层、业务层和控制层分别采用 @Repository、@Service 和 @Controller 对分层中的类进行注释，而用 @Component 对那些比较中立的类进行注释
