Question

我在尝试轮询JPA实体Person时遇到以下错误。代码中没有错误。一切都使用mvn clean install编译好，而且Person实体确实存在于net.lr.tutorial.karaf.camel.jpa2jms.model包中。我已经安装了我认为的所有必要功能，并且我知道它正确连接到数据库，因为它为主键创建了一个序列数据库。

有什么想法吗？

Answer 1

您可以尝试以下方法：

如果可能，请删除name注释的@Entity属性。
检查Person类是否添加了正确的persistence.xml类。它应该是net.lr.tutorial.karaf.camel.jpa2jms.model.Person而不是jms.model.Person

我希望，这有帮助。
