以上这些是异常信息，我确定我是执行这条语句出错：
hibernateTemplate.get(Client.class, id);
我也确定id有值 比如10001是数值型int,
百思不得其解，赐教！

有人说是下标越界，
我查了原码：
public char charAt(int index) {
if ((index < 0) || (index >= value.length)) {
throw new StringIndexOutOfBoundsException(index);
}
return value[index];
}
我不明白，它为什么会跑到这里，
我换了多种hql写法，比如：
String hql= "select c1.client from Clevel c1 where c1.client.id=?";
Client client =(Client)session.createQuery(hql)
.setParameter(0, id)
.uniqueResult();
都出现：
java.lang.StringIndexOutOfBoundsException: String index out of range: 0
at java.lang.String.charAt(String.java:658)
我的数据库也有数据啊！
