休眠映射最近失败，并出现 SAX 解析器异常：必须声明元素"hibernate-mapping"

Question

i newbie在这里。

我的故障排除是从一天到另一天，我无法部署我的项目。我已经恢复了此问题之前的所有修改，但没有成功，它仍然给新异常带来。

尚未修改冬眠模型，尚未修改数据库。

实际上我不知道发生了什么。

我们在这里有一个非常相似的问题，但是有一个冬眠的逆向工程文件，而不是冬眠映射文件。在我们的情况下，自2018年11月以来，该文件本身就没有被修改，但上周下旬停止工作。在诊断我们的问题时，当我在构建中设置一些断点时，我发现Saxparserexception仅在XML Parser创建的错误记录器中返回的第一个错误。事实证明，文件中的每个XML元素都以相同类型的错误标记：

org.xml.sax.saxparseexception element type "hibernate-reverse-engineering" must be declared

解析器发现了498个错误，即使只有第一个错误。

在我们案件中解决该问题的是什么是在Hibernate.Reveng.xml文件中更改： <!DOCTYPE hibernate-reverse-engineering PUBLIC "-//Hibernate/Hibernate Configuration DTD 3.0//EN" "http://www.hibernate.org/dtd/hibernate-reverse-engineering-3.0.dtd">

to

<!DOCTYPE hibernate-reverse-engineering SYSTEM "https://hibernate.org/dtd/hibernate-reverse-engineering-3.0.dtd" >

也就是说，我们从使用公共标识符转换为系统标识符，从HTTP更改为https。

原始表格(公共形式(是我们从以前的hibernate.org(jboss.org(文档(从Hibernate 3.2时范围内(获得的。新的是我们今天查看Hibernate反向工程的JBOSS文档。我猜是，您需要与Hibernate映射文件(Hibernate.xml或HBM.XML或您使用的任何名称(进行类似的更改，以至少使用HTTP代替HTTP，并可能将Doctype更改为：p> <!DOCTYPE hibernate-mapping SYSTEM https://hibernate.org/hibernate-mapping-3.0.dtd">

如果这无济于事，请尝试将您的Hibernate.xml文件添加到该问题(删除尽可能多的敏感信息之后(。
