Java 获取表示类未与命名查询映射的错误

我使用的是spring数据Jpa，我想将一个名为Client的表映射到名为ClientList的类中，并得到一个错误，即在命名查询中没有映射客户端[SELECT c FROM Client c]

这是我的实体类和获取错误代码 HH000177:命名查询中出错：GetAllClient org.hibernate.hql.internal.ast.QuerySyntaxException:未映射客户端[从客户端c中选择c]

---

由于没有将NamedQuery定义为本机查询，因此需要使用java类定义的名称[表和列的名称]，而不是JPA注释定义的名称

---

在您的示例中，在命名查询定义中使用“ClientList”作为表名。

您的实体名称是

ClientList

，因此您的查询应该是

从ClientList c

中选择c来编写命名的HQL或JPQL查询，而不是SQL查询。这里

client

是表名。使用

@namedNAVIQUERY

进行命名SQL查询。好的，谢谢。我会检查谢谢@satytnv正在工作
