java.lang.ClassCastException: [Ljava.lang.Object; cannot be cast to

Query q = currentSession().createSQLQuery("select * from Spitter where username = '"+username+"'");
List<Spitter> list = q.list();

因为createSQLQuery默认不支持转实体类，默认只返回Object类型。

改成下面即可返回对应实体类

Query q = currentSession().createSQLQuery("select * from Spitter where username = '"+username+"'").addEntity(Spitter.class);
List<Spitter> list = q.list();
Spitter s = list.get(0);
