Hibernate 3.5 抛出“org.dom4j.DocumentException：文档 http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd 第 1 行错误”

Question

我的 Hypersistence Optimizer 代码库中有一些 Hibernate 3.5 测试，现在我收到了这个奇怪的错误：

org.hibernate.InvalidMappingException: Could not parse mapping document from resource hbm/mapping/association/EagerFetchingManyToOneFetchJoinHbmTest.hbm.xml

所有这些测试都运行良好 3 年，所以这可能是最近发生的更改。

该问题是由最近在 hibernate.org 网站上设置的 HTTP->HTTPS 重定向引起的：

问题在于 Hibernate 3.5 无法正确处理此问题。

所以，解决方案非常简单。

将 HBM​​ 文件开头的 DTD DOCTYPE 定义从： 更改

<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">

为：

<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
