!DOCTYPE hibernate-configuration PUBLIC  
          "-//Hibernate/Hibernate Configuration DTD 3.0//EN"  
          "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">

我的hibernate.cfg.xml文件中有这个。我在eclipse工作区的WEB-INF文件夹中下载了jar（来自http://www.javatpoint.com/src/hb/hibernatejar.zip）。仍然说hibernate.sourceforge.net无法访问。我用www.hibernate.org/dtd替换它，这也是同样的错误。请帮我解决这个问题。

映射文件中也存在同样的问题。

在DOCTYPE中添加类路径后出错：

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.

Answer 1

您的DOCTYPE定义是指DTD上的hibernate.sourceforge.net。现在DTD存在（我可以通过Firefox浏览），但您的应用程序无法访问它。 doctype元素的目的是链接到DTD。

尝试使用以下

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

Answer 2

以下应该是 hibernate.cfg.xml 文件中的完整DTD

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

另外不要忘记在文件的开头跟着

<?xml version='1.0' encoding='utf-8'?>
