這是公司表映射
<hibernate-mapping>
<class name="com.tangziyi.entity.Company"
table="t_company">
<id name="cid" column="cid">
<generator class="native"></generator>
</id>
<property name="cName" column="cName"></property>
<property name="cAddress" column="cAddress"></property>
<set name="setStaff">
<key column="csid"></key>
<one-to-many class="com.tangziyi.entity.Staff"/>
</set>
</class>
</hibernate-mapping>
這是員工表的映射
<hibernate-mapping>
<class name="com.tangziyi.entity.Staff"
table="t_staff">
<id name="sid" column="sid">
<generator class="native"></generator>
</id>
<property name="sName" column="sName"></property>
<property name="sGender" column="sGender"></property>
<property name="sPhone" column="sPhone"></property>
<many-to-one name="company" class="com.tangizyi.entity.Company" column="csid"></many-to-one>
</class>
</hibernate-mapping>
這是核心組態檔
<hibernate-configuration>
<session-factory>
<!-- 第一部分：配置資料庫>
<property name="hibernate.connection.driver_class">
com.mysql.jdbc.Driver
</property>
<property name="hibernate.connection.url">
jdbc:mysql:///hibernate_day03
</property>
<property name="hibernate.connection.username">root</property>
<property name="hibernate.connection.password">123</property>
<!-- 第二部分：配置hibernate資訊>
<property name="hibernate.show_sql">true</property>
<!-- 用于格式化sql陳述句 -->
<property name="hibernate.format_sql">true</property>
<!-- 如果hibernate想自動創建表，需配置如下：
其中update的含義是如果表已經存在則更新，沒有則新建
-->
<property name="hibernate.hbm2ddl.auto">update</property>
<!-- 配置資料庫方言 -->
<property name="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</property>
<!-- 配置session與本地執行緒系結 -->
<property name="hibernate.current_session_context_class">
thread
</property>
<!-- 第三部分：將映射組態檔引入核心組態檔 -->
<mapping resource="com/tangziyi/entity/Company.hbm.xml"/>
<mapping resource="com/tangziyi/entity/Staff.hbm.xml"/>
</session-factory>
</hibernate-configuration>
這是測驗建表時的exception

全路徑，全類名檢查了無數次沒問題，實在找不到問題在哪啊，求大神給看看
