java - session.getCurrentSession().createCriteria(MyClass.class) 已弃用如何使用 .addOrder() 现在

Question

我一直在开发:

public List<DepartmentType> getAllDepartmentTypes() {
    return session.getCurrentSession()
                .createCriteria(DepartmentType.class)
                .addOrder(Order.asc("department_type_name"))
                .list();
}

地点:

@Autowired
SessionFactory session;

来自this Question关于 createCriteria() 的替代方案，我创建了一个获取列表的方法:

public List<DepartmentType> getAllDepartmentTypes() {
    CriteriaBuilder builder = session.getCurrentSession().getCriteriaBuilder();
    CriteriaQuery<DepartmentType> criteriaQuery = builder.createQuery(DepartmentType.class);    
    return session.getCurrentSession()
                .createQuery(criteriaQuery)
                .getResultList();
}

但我还是不知道在哪里使用:

addOrder(Order.asc("department_type_name"))

Answer 1

您需要使用CriteriaQuery.orderBy()提供 order by 子句。

public List<DepartmentType> getAllDepartmentTypes() {
    CriteriaBuilder builder = session.getCurrentSession().getCriteriaBuilder();
    CriteriaQuery<DepartmentType> criteriaQuery = builder.createQuery(DepartmentType.class);    
    Root<DepartmentType> deptType = criteriaQuery.from(DepartmentType.class);
    criteriaQuery.select(deptType).orderBy(builder.asc(deptType.get("department_type_name")));
    return session.getCurrentSession()
                .createQuery(criteriaQuery)
                .getResultList();
}
