java - Hibernate 映射在离线模式下不工作

Question

我们正在进行灾难恢复练习，一些 Hibernate+Spring 应用程序没有启动并出现以下错误

hbm 映射 XML 文件有

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
"http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 

在 SO 和 Hibernate 论坛上搜索修复看起来我们需要将文档类型中的 DTD 设置为 SYSTEM 以便它从本地系统读取而不是在 sourceforge.net 上托管的公共(public) dtd

<!DOCTYPE hibernate-mapping SYSTEM "hibernate-mapping-3.0.dtd">

但是有了这个 Hibernate 正在寻找应用服务器根文件夹中的文件

应该如何指定 SYSTEM DTD 引用，以便 Hibernate 从 hibernate.jar 中读取 DTD 而不是在文件系统中查找它？

Answer 1

查看 DTDEntityResolver 的 hibernate 源 http://grepcode.com/file/repo1.maven.org/maven2/org.hibernate/hibernate-core/3.3.1.GA/org/hibernate/util/DTDEntityResolver.java#DTDEntityResolver以下对我们有用

<!DOCTYPE hibernate-mapping SYSTEM "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"> 

为开源而欢呼!
