我是和视频学的，查了很久也没看出问题。郁闷呀。如果哪位大哥有学习Java更快更有效的方法，希望不吝赐教。在这里先谢谢了

问题补充：代码贴上去了，不知道对不对
问题补充：我不是用annotation做的，没@Entity

问题补充：shadabing 写道你实体类上有了注解，就不要配置xml映射
我重新弄了一边，发现有一句话没写。当时还是有问题，但第二天就没事了。奇了怪了。你说的问题的也有，后来改过来了，你很厉害，谢谢你帮了这么多忙，是条汉子
采纳的答案
哈哈,你还没给分了
你实体类上有了注解，就不要配置xml映射
你上传整个代码吧
The processing instruction target matching "[xX][mM][lL]" is not allowed.
这个异常解释为：xml文件不能被解析，一般出现这样的问题在于xml格式上，并且问题多出现在xml文件的头部。总结：&?xml version="1.0" encoding="UTF-8"?&前面不要有任何其他字符，如空格、回车、换行这些否则就会出现上面的异常。
&mapping class="com.majiacen.hibernate.model.Teacher"&
忘记写/
&mapping class="com.majiacen.hibernate.model.Teacher/"&
Exception in thread "main" org.hibernate.InvalidMappingException: Unable to read XML
main主线程里读不到XML文件& 贴贴entiyt类出来看看
贴代码，估计映射文件有问题
