nutzBook里面是实现方法直接写到userService里面了，但是我有点强迫症，喜欢都分开，所以有userService 和userServiceImpl，但是在mainSetup里面获取的时候就报错了，下面贴上代码：

public interface UserService {
	User add(String name, String password);
	int fetch(String username, String password);
	void updatePassword(int userId, String password);
	
}

@IocBean(fields="dao")
public class UserServiceImpl extends IdNameEntityService<User> implements UserService  {

  //。。。实现方法

}

mainSetup 里面代码：

// 初始化默认根用户
        if (dao.count(User.class) == 0) {
            UserService us = ioc.get(UserService.class);
            us.add("admin", "123456");
        }

。。尴尬，可以了，impl的iocBean 要加上name属性

后面做email的时候有这种配置

话说，你用的是什么版本？
