//添加《项目类型》

//return userService.addProjectType(projectType, result, status);

return userService.addProjectType(projectType);

}

}

3.3 DAO@Component("userDao")

public class UserDaoImpl implements UserDao{

@Autowired

private SessionFactory sessionFactory;

public ProjectType getById(int id)

{

return (ProjectType) sessionFactory.getCurrentSession().get(ProjectType.class, id);

}

@Override

public String userLogin(UserModel user) {

return "123456";

}

//获取数据

@Override

@SuppressWarnings("unchecked")

public List<ProjectType> getAllProjectTypes() {

Criteria ceriteria = sessionFactory.getCurrentSession().createCriteria(ProjectType.class);

return ceriteria.list();

}

//新增数据；

@Override

// @Transactional(readOnly = true, propagation = Propagation.REQUIRED)

public int save(ProjectType projectType) {

System.out.println("save:---");

System.out.println(projectType.getIndex());

System.out.println(projectType.getProjectType());

System.out.println(projectType.getProjectTypeAbbr());

return (Integer) sessionFactory.getCurrentSession().save(projectType);

}

}

Java web request获取Integer类型参数id失败
