请大家帮忙解决一下。 hibernate
[解决办法]
错误信息说com/test/hibernate/User.hbm.xml第二行出错，应该就在<hibernate-configuration>之前的部分，建议你去找一个正确的xml映射文件然后复制头部过来，光是这么看很难看出错误在哪，也许就是一两个字符的问题，

这不都写着：
Caused by: org.dom4j.DocumentException: Error on line 2 of document : The processing instruction target matching "[xX][mM][lL]" is not allowed. Nested exception: The processing instruction target matching "[xX][mM][lL]" is not allowed.
[解决办法]
你User.hbm.xml中
<class name="com.test.hibernate.User" table=User>
少了类名,你只写了包路径没有跟上类,hibernate内部反射的时候无法解析的
