上面这段配置中一直抛出一下异常

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in class path resource [spring/applicationContext.xml]: Invocation of init method failed; nested exception is org.hibernate.InvalidMappingException: Unable to read XML

弄了一上午也找不到原因，头都炸了

后面看到一个贴说是*.hbm.xml 中内容有错，我就一行一行检查，可是还是没发现有什么错误，最后。。。。。。最后，竟然是因为dtd后面多以一个空格导致的

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN"

"http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd ">把dtd后面的空格删除，就把问题解决了
