这是啥原因造成的？

[解决办法]
This behavior can happen if there is any illegal character in the header before the starting <hibernate-mapping> tag. This even can be a non-printable character.

映射文件
Person.hbm.xml
是不是有什么不正确的字符，xml格式化一下。或者是header有错误。。
[解决办法]

Java code

Exception in thread "main" org.hibernate.InvalidMappingException: Could not parse mapping document from resource it/cast/hibernate/domain/Person.hbm.xmlCaused by: org.hibernate.InvalidMappingException: Could not parse mapping document from invalid mapping
[解决办法]
应该是mapping文件有错吧，仔细检查下
