休眠无效映射异常

Question

我正在使用最新的jars进行休眠。 （即hibernate-release-4.0.1.Final） 在以前的版本中，我得到了正确的输出。 我更换了hibernate jar，并且出现异常。

org.hibernate.InvalidMappingException：无法读取XML

我看了一些博客和改变了DOCTYPE到

<?xml version='1.0' encoding='UTF-8'?> 
<!DOCTYPE hibernate-configuration PUBLIC 
      "-//Hibernate/Hibernate Configuration DTD 3.0//EN" 
      "http://www.hibernate.org/dtd/hibernate-configuration-3.0.dtd"> 

仍然是错误仍然存​​在。

我附上我的cfg.xml文件和我的hbm.xml之一（如所有10个不能被附后）

Plez让我有什么问题，什么应该是解决方案。 谢谢

Answer 1

检查了这一点

 <set name="setPhones" cascade="all" lazy="true"> 
      <key column="EMPLOYEE_ID" not-null="true" **cas**></key> 
      <one-to-many class="Phone"/> 
     </set> 

从您附加的日志“从日志属性名称”cas“与一个元素类型”key“相关联后必须紧跟着'='字符。嵌套异常：与元素类型“键”关联的属性名称“cas”后面必须跟有'='字符。“ 是问题的原因。”

“没有称为”cas“的属性。
