用Hibernate时出错.请高手帮忙解决一下.
用Hibernate 时 出现这个错误SessionFactory 创建不成功,是怎么回事?
是不是映射文件写错了.但是映射文件是 自动生成的,不应该有错吧.
请哪位大峡 帮的看一下:
%%%% Error Creating SessionFactory %%%%--------------------编程问答-------------------- 你使用的是集成spring吗？ --------------------编程问答-------------------- 单独的hibernate,是不是有些jar没导入？ --------------------编程问答-------------------- 需要的jar包都导入进去了,spring 算是没有用到.没用spring的容器去创建.一些类是我自己创建的. --------------------编程问答-------------------- 1、*.hbm.xml文件的路径不对。这分两个小点，一是本身这个文件的位置没有放对，二是hibernate.cfg.xml中配置的路径不对，这就取决于我们喜欢改那个地方了。

2、*.xml的文件中存在语法错误。一般用工具生成的xml文件不会存在这类错误，但是对于像我这样的初学者，喜欢自己去手动配置，这就难免会遇到输入错误的情况。
百度到的，你看下是不是在这里面 --------------------编程问答-------------------- 你把你的application.xml的内容贴出来，里面有个bean是管理sessionFactory的，里面有个classpath:hibernate.cfg.xml，这个你有写吗 --------------------编程问答-------------------- 最好把 web.xml、hbm.cfg.xml等等xml文件内容粘贴出来看看
错误：“Unable to read XML”

--------------------编程问答-------------------- 检查一下你的 驱动类，应该是 class14.jar才对
--------------------编程问答-------------------- 从异常上来看是由你的xml配置文件引起的。 --------------------编程问答-------------------- 这是web.xml 里面的内容:
<display-name>books_family</display-name>
<!-- Set Charcter Encoding -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>
/WEB-INF/classes/config/applicationContextDao.xml,
/WEB-INF/classes/config/book_dao.xml,
/WEB-INF/classes/config/book_service.xml,
/WEB-INF/classes/config/book_servlet.xml
</param-value>
</context-param>
你把你的application.xml的内容贴出来，里面有个bean是管理sessionFactory的，里面有个classpath:hibernate.cfg.xml，这个你有写吗
用到的类,我是自己手动创建的.这个配置 可以不用吧?? --------------------编程问答-------------------- spring 自动帮你托管了，你自己建立不出来的，我前两天试过。 --------------------编程问答-------------------- /WEB-INF/classes/config/book_servlet.xml
这不是编译后的文件吗 大哥src里的才是源码啊。。 --------------------编程问答-------------------- 继承的hibernateDao的dao里，直接覆写spring 的hibernateDao的SessionFactory getSessionFactory() 方法就行了。
--------------------编程问答-------------------- 我在Dao 层 测试了一下。能取到数据。 在service层也测试了一下。独自运行的话，都是可以取到数据的。但是一启动Tomcat 取数据的时候就会出问题！
补充：Java , Web 开发
