本文介绍了一种在Spring+Hibernate项目中遇到的HQL查询异常问题及其解决方案。该异常主要表现为ClassNotFoundException，通过调整Hibernate的查询解析器配置解决了问题。

最近在项目中用weblogic跑Spring+hibernate的运用(在websphere中正常运行)

抛出如下的异常

org.springframework.orm.hibernate3.HibernateQueryException: ClassNotFoundException: org.hibernate.hql.ast.HqlToken [from com.datastage.model.TmdDatastageXm project where project.jqbh=?]; nested exception is org.hibernate.QueryException: ClassNotFoundException: org.hibernate.hql.ast.HqlToken [from com.datastage.model.TmdDatastageXm project where project.jqbh=?]org.hibernate.QueryException: ClassNotFoundException: org.hibernate.hql.ast.HqlToken [from com.datastage.model.TmdDatastageXm project where project.jqbh=?]
        at org.hibernate.hql.ast.HqlLexer.panic(HqlLexer.java:57)
        at antlr.CharScanner.setTokenObjectClass(CharScanner.java:340)
        at org.hibernate.hql.ast.HqlLexer.setTokenObjectClass(HqlLexer.java:31)

使用Spring+hibernate如下xml 代码

<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.cglib.use_reflection_optimizer">true</prop>
</props>
</property>

在配置中加以下属性就可以解决
<prop key="hibernate.query.factory_class">org.hibernate.hql.ast.ASTQueryTranslatorFactory</prop>

新增后的xml 代码

<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">org.hibernate.dialect.OracleDialect</prop>
<prop key="hibernate.show_sql">false</prop>
<prop key="hibernate.cglib.use_reflection_optimizer">true</prop>
<prop key="hibernate.query.factory_class">org.hibernate.hql.classic.ClassicQueryTranslatorFactory</prop>
</props>
</property>
