Question

此代码无效：

getHibernateTemplate()
                .find("from elephant.model.Setup s where s.settingName = ?",setupName);

错误：位置超出声明的序数参数的数量。请记住，序数参数是基于1的！位置：1;嵌套异常是org.hibernate.QueryParameterException：超出声明的ordinal参数数量的位置。请记住，序数参数是基于1的！位置：1

如果我将代码更改为：

getHibernateTemplate()
                .find("from elephant.model.Setup s where s.settingName = :setupName",setupName);

我有同样的错误。我怎么解决它？

...后

我会改变这样的查询：

.find("from elephant.model.Setup s where s.settingName = \"AutoAccessControl\"")

现在我们还有其他错误：

2563 [main] WARN org.hibernate.hql.QuerySplitter - no persistent classes found for query class: from elephant.model.Setup s where s.settingName = "AutoAccessControl"

Answer 1

您确定此查询是否失败 - 您是否可以尝试连接查询中的值以进行检查。

第一个版本应该有效 - 第二个版本不行 - 你需要使用findByNamedParam。

Spring + Hibernate，嵌套异常是org.hibernate.QueryParameterException：超出声明的ordinal参数数量的位置
