Answer 1

/jp/co/mySpring/sys/demo/entity下有demo.hbm.xml和Demo.java，编译后的class/jp/co/mySpring/sys/demo/entity下也有demo.hbm.xml和Demo.class，请问是什么原因造成的异常哈？

Answer 2

建议楼主看一下tomcat的日志里面报的错误

Answer 3

看这里
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'demoSessionFactory'
这个工厂类存在么？
