Question

this.getHibernateTemplate().find(hql, new Object[]{parent_id});参数设置的问题

public ArrayList<Area> findAllArea(int parent_id) {
String hql = "from Area area where area.parent_id=?";
List<Area> areaList = null;
System.out.println(hql);
areaList = (ArrayList<Area>) this.getHibernateTemplate().find(hql,
new Integer[] { parent_id });
this.getHibernateTemplate().find(hql, new Object[]{parent_id});
areaList = this.getHibernateTemplate().find(hql);
return (ArrayList<Area>) areaList;
}

报错为：
org.springframework.orm.hibernate3.HibernateQueryException: Expected positional parameter count: 1, actual parameters: [] [from Area area where area.parent_id=?]; nested exception is org.hibernate.QueryException: Expected positional parameter count: 1, actual parameters: [] [from Area area where area.parent_id=?]

楼主试试lazy="false" 就是延迟

这有篇延迟加载的介绍：
