hibernate出现net.sf.hibernate.MappingException: Error reading resource:
点击右边红色标题查看本文完整版：hibernate出现net.sf.hibernate.MappingException: Error reading resource: pojo/Mychild.hbm
我参考一篇文章,http://blog.csdn.net/cooperking/archive/2004/12/28/231934.aspx
? 照着做了一下.
? 第一步,我没有配置<many-to-one>关系,做了一个查询,存储.成功了.说明例子是可以跑通的.
? 第二步,我配置了Mychild.hbm ,Myparent的对应关系.又写了一个测试小例子,该例子出错了.
? 可能是表结构不对,出现了下面的问题:请大家帮忙看看.
? ERROR - Error parsing XML: XML InputStream(30) The content of element type "class" must match "(meta*,(cache|jcs-cache)?,(id|composite-id),discriminator?,(version|timestamp)?,(property|many-to-one|one-to-one|component|dynamic-component|any|map|set|list|bag|idbag|array|primitive-array)*,(subclass*|joined-subclass*))".
? net.sf.hibernate.MappingException: Error reading resource: pojo/Mychild.hbm
?
?
? 环境: eclipse's hibernate插件 , mysql数据库.
? 数据库:create table mychild( cid int ,cname varchar(20) , pid int ) ;
? create table myparent( pid int ,pname varchar(20) ) ;
? 使用eclipse's hibernate插件建立的配置文件hibernate.cfg.xml 如下:
? <?xml version="1.0" encoding="utf-8"?>
? <!DOCTYPE hibernate-configuration
? PUBLIC "-//Hibernate/Hibernate Configuration DTD//EN"
? "http://hibernate.sourceforge.net/hibernate-configuration-2.0.dtd">
?
? <hibernate-configuration>
? <session-factory>
? <!-- local connection properties -->
? <property name="hibernate.connection.url">
? jdbc:mysql://localhost:3306/test
? </property>
? <property name="hibernate.connection.driver_class">
? com.mysql.jdbc.Driver
? </property>
? <property name="hibernate.connection.username">root</property>
? <property name="hibernate.connection.password" />
? <!-- property name="hibernate.connection.pool_size"></property -->
? <!-- dialect for MySQL -->
? <property name="dialect">
? net.sf.hibernate.dialect.MySQLDialect
? </property>
? <property name="hibernate.show_sql">false</property>
? <property name="hibernate.use_outer_join">true</property>
?
? <mapping resource="pojo/Mychild.hbm" />
? <mapping resource="pojo/Myparent.hbm" />
? </session-factory>
? </hibernate-configuration>
?
?
?
? 使用插件建立的影射文件如下:
? ===================
? Mychild.hbm
? ===================
? <?xml version="1.0"?>
? <!DOCTYPE hibernate-mapping PUBLIC
? "-//Hibernate/Hibernate Mapping DTD//EN"
? "http://hibernate.sourceforge.net/hibernate-mapping-2.0.dtd" >
?
? <hibernate-mapping package="pojo">
? <class name="Mychild" table="mychild">
? <property
? column="pid"
? length="11"
? name="Pid"
? not-null="false"
? type="integer"
? />
? <property
? column="cid"
? length="11"
? name="Cid"
? not-null="false"
