将Hibernate应用程序移动到JBoss-位置超过声明的序数参数的数量

Question

我有一个Hibernate Web应用程序，目前正在tomcat/CloudFoundry上运行，但当我尝试在JBoss上运行它时，我遇到了一些错误。

在我的DAO中，我创建了一个查询来按用户名加载用户，如下所示：

Query query = getEntityManager().createQuery("select u from com.tmm.enterprise.socialcv.security.Account u where u.userName = ?1");
query.setParameter(1, userName);

当我在Tomcat上运行应用程序时，上面的方法是有效的，但是当我在JBoss上运行应用程序时，我得到了以下错误：

16:31:47,639 DEBUG [org.springframework.web.servlet.DispatcherServlet] (http-localhost-127.0.0.1-8080-1) Handler execution resulted in exception - forwarding to resolved error view: ModelAndView: reference to view with name 'dataAccessFailure'; model is {exception=org.springframework.dao.InvalidDataAccessApiUsageException: org.hibernate.QueryParameterException: Position beyond number of declared ordinal parameters.

我已经尝试更改为以下两个问题，但仍然没有成功：

Query query = getEntityManager().createQuery("select u from com.tmm.enterprise.socialcv.security.Account u where u.userName = ?");
        query.setParameter(0, userName);

上面给我同样的错误。因为：

Query query = getEntityManager().createQuery("select u from com.tmm.enterprise.socialcv.security.Account u where u.userName = ?");
        query.setParameter(1, userName);

切换到命名参数会导致无法定位命名参数的错误。

有什么想法吗？（顺便说一句，在JBoss上的查询中，我还必须将DAO更新为完全限定的帐户-在tomcat上，它只是在查询帐户）

Answer 1

query = getEntityManager().createQuery(
"select u from com.tmm.enterprise.socialcv.security.Account u where u.userName = :userName");
query.setParameter("userName", userName);

Answer 2

基于Hibernate HQL参考，如果您使用JDBC位置样式，您只需要使用<代码> 。如果您使用的是命名参数，则应使用：paramName。

Answer 3

我用那种方法纠正了这样的错误

schema.table = ' ?' ->error

schema.table = '?' ->no error

也许这对某人有帮助。
