hibernate 配置文件加载异常，解决日志

问题描述：

我用的是ssh,框架。用了 hibernate的逆向工程生成  hibernate.cfg.xml（主配置文件）hibernate.hbmxml（实体的映射文件）。项目之前运行的好好的。有时就突然

异常。但是有时重启下就好了。直到今天实在没办法才解决。

异常如下：

问题原因：

在经过一番挣扎后，解决。是生成的头文件 xml文件问题导致。无法解析。

解决办法：

找到 hibernate.jar 拿出 两个hibernate.cfg.xml（主配置文件）hibernate.hbmxml（实体的映射文件）的DTD文件。打开复制头文件。替换到项目中。

之前：

<?xml version='1.0' encoding='UTF-8'?><!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd"><!--     Mapping file autogenerated by MyEclipse Persistence Tools-->

之后

<?xml version="1.0" encoding="utf-8"?><!DOCTYPE hibernate-mapping PUBLIC     "-//Hibernate/Hibernate Mapping DTD 3.0//EN"    "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
