从 Object 转换为 Class :失败
cast from Object to Class : failed
我收到这个错误
Exception in thread "main" java.lang.ClassCastException:
[Ljava.lang.Object; cannot be cast to xxx.xxx.xxx.Terminal
当我尝试这段代码时;那怎么了??
for(int k=0;k<argTerminal.length;k++){
String hql = "select crimpkontakt from Terminal where id="+argTerminal[k];
Query query = session.createQuery(hql);
query.setMaxResults(1);
Terminal nameTerminal = (Terminal) query.uniqueResult();
如果您想 select 终端对象,您的 HQL 应如下所示:
String hql = "from Terminal where id="+argTerminal[k]
另外为了避免SQL注入,使用参数API是首选:
Query query = session.createQuery("select from Terminal where id = :id");
query.setString("id", argTerminal[k]); // I assume that id is a String here
query.setMaxResults(1);
如果 id
是主键则更好,您可以使用 session.get(Terminal.class, argTerminal[k])
