我正在使用hibernate 3，下面的方法一次可以完美运行，但是第二次使用另一种方法调用它时，我收到一条错误消息：
16:51:45,371 INFO [org.hibernate.type.IntegerType] (http-localhost-127.0.0.1-8081-2) could not bind value '812' to parameter: 2; java.lang.String cannot be cast to java.lang.Integer
16:51:45,442 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/sg].[Faces Servlet]] (http-localhost-127.0.0.1-8081-2) "Servlet.service()" pour la servlet Faces Servlet a généré une exception: java.lang.ClassCastException: java.lang.String cannot be cast to java.lang.Integer
由于调试模式，我已经验证并且代码实际上是一个整数，我不明白为什么错误消息是关于字符串的。
谢谢。
public BureauModification getDerniereModification(Integer code) {
List listBureau = getHibernateTemplate().findByNamedQueryAndNamedParam("bureau.detail.last", "codeBureau", code);
if (!listBureau.isEmpty()) {
return (BureauModification) listBureau.get(0);
}
return null;
}
<query name="bureau.detail.last"
comment="Détail d'un bureau à partir du code Bureau">
<![CDATA[FROM BureauModification WHERE (code, dateMiseAJour) IN (SELECT code, MAX(dateMiseAJour) FROM BureauModification WHERE code = :codeBureau GROUP BY code)]]>
</query>
完整的堆栈跟踪：
