纠结很久的问题 在SSH下，Dao Service 下 baseService 为NULL的问题

public class UserServiceImpl extends BaseServiceImpl<User> implements UserService{
private UserDao userDao;

public UserDao getUserDao() {
return userDao;
}


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

}

}

UserServiceImpl 调用 BaseServiceImpl的 通用save方法会遇到baseDao为NULL

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

}

添加

super.setBaseDao(userDao);
