大家先见如下代码：
public String findZGAndManigerByHandDepartment(String sheetHandDepartment){
System.out.println("传入的部门ID为："+sheetHandDepartment);
HibernateTemplate ht = getHibernateTemplate();
final String str = sheetHandDepartment;
return (String) ht.execute(new HibernateCallback() {
public Object doInHibernate(Session session) throws
HibernateException {
Query queryRoot = session
.createSQLQuery("select {o.*} from TBL_DEPARTMENTS {o} where {o}.DEPARTMENT_ID='"+str+"'", "o", Department.class);
Iterator iter = queryRoot.list().iterator();
if (iter.hasNext()) {
Department ctvo = (Department) iter.next();
String sheetHand = ctvo.getParentID();
if (sheetHand.length()>1){
findZGAndManigerByHandDepartment(sheetHand);
}
System.out.println("返回的部门ID为："+ctvo.getDeptID());
return ctvo.getDeptID();
}
return "";
}
});
}
调用该方法时传入参数为：findZGAndManigerByHandDepartment("8a74885a2f30559f012f8bb287430772");
你们假如这个递归只是被调用了三次，形如：
传入的部门ID为：8a74885a2f30559f012f8bb287430772
传入的部门ID为：8a74885a2f30559f012f8bb0e8dc074a
传入的部门ID为：ff8080812dc1758a012dc556ed0900ed
那么System.out.println("返回的部门ID为："+ctvo.getDeptID());这句话会执行多少次呢？产生的原因是什么呢？怎么解决呢？

是九次吗？

不对，看循环几次，然后乘以三
