在Hibernate中是否可以使用运算符,而您不知道提前类型?这是上下文的一些示例代码,显示了我希望它如何工作:
s.createQuery("select from :table where column :op :value");
那行不通,所以我写了这个switch
逻辑:
public List<Model> findByProperty(final String propertyName,
final String operator,
final String value) {
final Session s = getSession();
Criteria criteria = s.createCriteria(Foo.class);
// How could I dynamically use the type of operator
// through Hibernate without perhaps a switch on operator
switch (operator) {
case '=':
criteria = criteria.add(Expression.eq(propertyName, value);
// ...
}
return criteria.list();
}
可以,但是还有其他方法吗?
谢谢!
