如何在hibernate中编写条件ORDERBY子句条件？

我需要在hibernate条件中转换以下查询

有人知道如何在hibernate中编写这个ORDERBY子句吗

select * from StudentMasterTable where SchoolId = 90 and SchoolName IS NOT NULL ORDER BY IIF(StudentType = 'O',StudentName,SchoolName)

---

我相信我这样做是为了处理动态orderBys：

//制作一个方法，该方法将接受一个字符串，我想这是您的studentType列（您可能应该为StudentMasterTable显示您的实体类，我假设studentType是字符串类型）

//然后做下面的事情

"select s from StudentMasterTable s where s.schoolId = '90' and s.schoolName is not    null
order by " +  orderByClause(s.studentType) + ",s.studentName,s.schoolName"; 

---

最后我找到了解决办法

我创建了一个自定义类来覆盖条件公式

public class customOrderBy extends Order {
    private String sqlFormula;


    protected OrderBySqlFormula(String sqlFormula) {
        super(sqlFormula, true);
        this.sqlFormula = sqlFormula;
    }

    public String toString() {
        return sqlFormula;
    }

    public String toSqlString(Criteria criteria, CriteriaQuery criteriaQuery) throws HibernateException {
        return sqlFormula;
    }


    public static Order customOrder(String sqlFormula) {
        return new OrderBySqlFormula(sqlFormula);
    }
}

我把这个叫做下面

criteria.addOrder(customOrderBy.customOrder("IIF(StudentType = 'O',StudentName,SchoolName)"));

---

我在请求中没有StudentType，我需要通过检查表或bean中的数据来查找基于标准的解决方案

criteria.addOrder(customOrderBy.customOrder("IIF(StudentType = 'O',StudentName,SchoolName)"));
