这是啥原因造成的？

Answer 1

Could not parse mapping document from resource it/cast/hibernate/domain/Person.hbm.xml
说找不到 Person.hbm.xml 文件 看看路径是不是写错了

Answer 2

觉得是jar包问题。
antlr-2.7.6.jar
c3p0-0.9.1.2.jar
cglib-2.2.jar
common-annotations.jar
commons-collections-3.1.jar
commons-fileupload-1.2.2.jar
commons-lang-2.5.jar
commons-logging.jar
dom4j-1.6.1.jar
ejb3-persistence.jar
freeer-2.3.18.jar
hibernate-annotations.jar
hibernate-cglib-repack-2.1_3.jar
hibernate-commons-annotations.jar
hibernate-core.jar
hibernate-entitymanager.jar
hibernate3.jar
javassist-3.12.0.GA.jar
jta.jar
log4j-1.2.15.jar
mysql-connector-java-5.1.19-bin.jar
ognl-3.0.4.jar
slf4j-api-1.5.2.jar
slf4j-log4j12.jar
spring.jar
struts2-core-2.3.1.2.jar
struts2-spring-plugin-2.3.1.2.jar
xwork-core-2.3.1.2.jar
上面这些看看是否都有。

Answer 3

是个单纯的Hibernate工程，没有spring跟strust
包应该都够了

Answer 4

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。。

Answer 5

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
很明显楼主你的Person.hbm.xml这个映射文件有问题，编译器不能解析，你好好检查检查你这个xml文件的特殊字符标签是不是匹配

Answer 6

应该是mapping文件有错吧，仔细检查下
