Hibernate 重复定义字段的错误

<?xml version="1.0"?><!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN""http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd"><hibernate-mapping ><class name="com.bjsxt.hibernate.User" ><id name="id"><generator class="uuid"></generator></id><property name="id"/><property name="name"/><property name="password"/><property name="createTime"/><property name="expireTime"/></class></hibernate-mapping>

 

提示错误 id (should be mapped with insert="false" update="false")

 

是由于重复定义引起  去掉一个Id 的定义即可
