Hibernate.cfg.xml解析错误 [英] Hibernate.cfg.xml parsing error

问题描述

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

我在我的hibernate.cfg.xml文件中有这个。我有下载的jar文件（来自 http://www.javatpoint.com/src/hb/ eclipse工作区中WEB-INF文件夹中的hibernatejar.zip ）。它仍然说hibernate.sourceforge.net是无法访问的。我用www.hibernate.org/dtd替换它，这也给出了相同的错误。请帮我解决这个问题。

映射文件同样存在问题。

在DOCTYPE中添加classpath后出现错误：

  log4j：WARN记录器（org.hibernate.cfg.Environment）中找不到appender。 
 log4j：WARN请正确初始化log4j系统。 
线程main中的异常org.hibernate.HibernateException：无法解析配置：hibernate.cfg.xml 
在org.hibernate.cfg.Configuration.doConfigure（Configuration.java:1491）
在org.hibernate.cfg.Configuration.configure（Configuration.java:1425）
在StoreData.main（StoreData.java:12）
引起：org.dom4j.DocumentException：未知协议：classpath嵌套异常：未知协议：类路径
在org.dom4j.io.SAXReader.read（SAXReader.java:484）
在org.hibernate.cfg.Configuration.doConfigure（Configuration.java:1481）
 ... 2 more 
  

解决方案

在 hibernate.cfg.xml 文件中完整的DTD

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

另外，请不要忘记在文件的开始部分追加

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

<

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

I have this in my hibernate.cfg.xml file. I have the jars downloaded (from http://www.javatpoint.com/src/hb/hibernatejar.zip) in WEB-INF folder in eclipse workspace. Still it says hibernate.sourceforge.net is unreachable. I replaced it with www.hibernate.org/dtd and that is also giving same error. Please help me fix this.

Same issue in mapping file as well.

Error after adding classpath in DOCTYPE:

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

解决方案

Following should be your complete DTD in hibernate.cfg.xml file

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

Also do not forget following at the start in the file

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