下面是我的代码：

@IocBean
public class UserDaoImpl extends BaseDao implements UserDao {

	@Override
	public IfmUser fetchUser(String userid) {
		return dao.fetch(IfmUser.class, Cnd.where("userid", "=", userid));
	}

	@Override
	public List<Record> qryRolesByid(String roleid) {
		// TODO Auto-generated method stub
		return null;
	}
}

-------------serivce有两个地方调用
@IocBean
public class UserServiceImpl extends BaseService implements UserService {

	@Inject 
	private UserDao userDao;
	
	@Override
	public CallBackBean qryuserList(String json) {
		Cnds cnds = Json.fromJson(Cnds.class, json);
		//cnds = SqlUtils.apCnd(cnds);
		List<Record> res = userDao.qryuserList(cnds);
		int count = userDao.countuserList(cnds);
		return joinformateJson(json, "success", count + "", res);
	}
}
