hibernate 不能解析映射文件

Question

我在我的项目下新建了一个映射文件，运行报错org.hibernate.InvalidMappingException: Could not parse mapping document from

我的实体映射文件如下<?xml version="1.0" encoding="utf-8"?>

错误在你的hibernate.cfg.xml里面，你的Barback.hbm.xml在那个文件里申明了两次吧。

这是我的hibernate配置文件。我不太明白楼上的师兄所说的错误是在哪？麻烦帮忙看下吧

我看了你的数据结构的图，映射的列名不一致吧。<property name="header" type="java.lang.String">
            <column name="header" length="20" />
        </property>映射的column name是 header，但是你数据库里的列名是B_HEADER，怎么不一样？
这个映射文件莫非是你自己写的为什么不用工具去生成呢？
