有什么建议吗?

这是一个临时解决方案。您的Hibernate jar包含用于验证配置xml的dtd。解压缩'hibernate-configuration-3.0.dtd'并将其放在项目结构的某个目录中(在本例中,我将它放在Project根目录中)。将您的dtd位置添加到DOCTYPE声明。
<!DOCTYPE hibernate-configuration SYSTEM
"hibernate-configuration-3.0.dtd">
它对我有用。它在系统脱机时有效。从本地系统获取DTD。
只是我们必须想办法从你的jar中获取dtd。
你可以这样做:<!DOCTYPE hibernate-configuration SYSTEM
"classpath://org/hibernate/hibernate-configuration-3.0.dtd">
然后,它正在抛出
Caused by: org.dom4j.DocumentException: unknown protocol: classpath Nested exception: unknown protocol: classpath
我收到连接超时错误。你的是连接拒绝错误。如果'hibernate.org'拒绝连接,请尝试此操作。

在Eclipse Java Project中,使用构建路径添加hibernate jar文件。在hibernate.cfg.xml(配置文件)中添加以下给定的DOCTYPE 同样在DOCTYPE之后的映射文件中(另存为example.hbm.xml-map类与数据库中的表)
