org.hibernate.hql.internal.ast.QuerySyntaxException: agency is not mapped

今天在使用hibernate+springmvc框架，做一个查询时出现了一个错误,sql语句大体为：

select count(id) from address where agency_id in (select id from agency where pids like '%,42,' or id=42) and shflag=0 order by id desc

在mysql查询中能够正常运行，在控制台中报错

java.lang.IllegalArgumentException: org.hibernate.hql.internal.ast.QuerySyntaxException: agency is not mapped [select c from com.demi.cms.model.Address c where agency_id in (select id from agency where pids like '%,42,' or id=42) and shflag=0 order by id desc] at org.hibernate.jpa.spi.AbstractEntityManagerImpl.convert AbstractEntityManagerImpl.java:1750) at org.hibernate.jpa.spi.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1677) at org.hibernate.jpa.spi.AbstractEntityManagerImpl.convert(AbstractEntityManagerImpl.java:1683) at org.hibernate.jpa.spi.AbstractEntityManagerImpl.createQuery(AbstractEntityManagerImpl.java:331) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source) at sun.reflect.DelegatingMethodAccessorImpl.invoke(Unknown Source) at java.lang.reflect.Method.invoke(Unknown Source)~~~~~~

提示我们是查询语法错误，后来仔细一想hibernate对大小写敏感，将语句重新更改了一下：

select count(id) from Address where agency_id in (select id from Agency where pids like '%,42,' or id=42) and shflag=0 order by id desc，问题解决！
