Java “冬眠例外”；无法分析配置：hibernate.cfg.xml；运行简单的Hibernate应用程序时出错

为什么会发生此hibernate异常？

这很可能是因为引用了您正在使用的hibernate jar中不存在的

hibernate.cfg.xml

顶部的DTD

假设您没有使用Hibernate 2.0版，请检查您的Hibernate.cfg.xml中是否有：

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
Exception in thread "main" org.hibernate.HibernateException: Could not parse configuration: hibernate.cfg.xml
    at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1491)
    at org.hibernate.cfg.Configuration.configure(Configuration.java:1425)
    at com.javatpoint.mypackage.StoreData.main(StoreData.java:13)
Caused by: org.dom4j.DocumentException: Connection refused: connect Nested exception: Connection refused: connect
    at org.dom4j.io.SAXReader.read(SAXReader.java:484)
    at org.hibernate.cfg.Configuration.doConfigure(Configuration.java:1481)

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

如果您使用XML hbm文件进行实体映射，那么在上面的XML文件中：

log4j:WARN No appenders could be found for logger (org.hibernate.cfg.Environment).
log4j:WARN Please initialize the log4j system properly.
Exception in thread "main" org.hibernate.HibernateException: Could not parse configuration: hibernate.cfg.xml

对于一个问题来说，这是一个糟糕的标题。请将其更改为描述您的问题的内容。另外，请添加更多信息，只是stacktrace没有多大帮助。ur

hibernate.cfg.xml

是不可解析的。请在问题中添加你的hibernate.cfg.xml文件内容。请上传你的配置文件…这实际上是两个问题：log4j和hibernate。关于hibernate已经有了一个答案，但是您还应该“正确初始化log4j”。据我所知，当未找到配置文件且未完成任何编程初始化时，会出现此警告。关于如何初始化它，请参阅log4j文档。
