我有一个正在使用tomcat / CloudFoundry的Hibernate Web应用程序,但是当我尝试在JBoss上运行它时,我遇到了一些错误。
在我的DAO中,我创建了一个按userName加载用户的查询,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,上面的工作正常,但是当我在JBoss上运行它时,我收到以下错误:

我已尝试更改以下两个查询,但仍然没有运气:
Query query = getEntityManager().createQuery("select u from com.tmm.enterprise.socialcv.security.Account u where u.userName = ?");
query.setParameter(0, userName);
上面给出了同样的错误。同样如下:
Query query = getEntityManager().createQuery("select u from com.tmm.enterprise.socialcv.security.Account u where u.userName = ?");
query.setParameter(1, userName);
切换到命名参数会给我一个关于无法找到命名参数的错误。
有什么想法吗? (顺便说一句,我还必须在JBoss的查询中将DAO更新为完全限定的帐户 - 在tomcat上它只是在查询帐户)

我以这种方式解决了这样的错误
schema.table = ' ?' ->error
schema.table = '?' ->no error
也许对某人有所帮助。

基于Hibernate HQL reference,如果使用JDBC位置样式,则仅必须使用?
。如果您使用的是命名参数,则应使用:paramName
。
答案 2 :(得分:0)
query = getEntityManager().createQuery(
"select u from com.tmm.enterprise.socialcv.security.Account u where u.userName = :userName");
query.setParameter("userName", userName);
答案 3 :(得分:0)
即使在我的情况下,没有任何工作,我已经尝试了
最后,我发现每次调用hashCode
时,生成的查询对象的参数列表都是空的。
解决方案: window.jQuery.Velocity
文件中缺少实体映射,添加后,它开始工作!!
