求解 Hibernate问题
今天在写映射关系，结果在配置文件上栽了跟头
这是junit的错误信息

这是映射文件
<class name="Role">
<id name="id">
<generator class="native"/>
</id>
<property name="name"/>
<property name="description"/>
<!-- users属性 ,我与user是一对多的关系-->
<set name="users">
<key column="departmentId"/>
<one-to-many class="User"/>
</set>
</class>
<hibernate-mapping package="com.graduation.oa.bean">
<class name="Role">
<id name="id">
<generator class="native"/>
</id>
<property name="name"/>
<property name="description"/>
<!-- users属性，我与user是多对多 -->
<set name="users" table="role_user" inverse="true">
<key column="roleId"/>
<many-to-many class="User" column="userId"/>
</set>
</class>
</hibernate-mapping>
<hibernate-mapping package="com.graduation.oa.bean">
<class name="User">
<id name="id">
<generator class="native"/>
</id>
<!-- department属性，我与department是多对一 -->
<many-to-one name="department" class="Department" column="departmentId" ></many-to-one>
<!-- roles属性，我与role是多对多关系 -->
<set name="roles" table="role_user" inverse="false">
<key column="userId"/>
<many-to-many class="Role" column="roleId"/>
</set>
<property name="loginName" type="string"/>
<property name="password" type="string"/>
<property name="name" type="string"/>
<property name="gender" type="string"/>
<property name="phoneNumber" type="string"/>
<property name="email" type="string"/>
<property name="description" type="string"/>
</class>
</hibernate-mapping>
这个是配置文件
<hibernate-configuration>
<session-factory>
<property name="dialect">
org.hibernate.dialect.MySQLDialect
</property>
<property name="hbm2ddl.auto">update</property>
<property name="show_sql">true</property>
<mapping resource="com/graduation/oa/bean/Department.hbm.xml" />
<mapping resource="com/graduation/oa/bean/Role.hbm.xml" />
<mapping resource="com/graduation/oa/bean/User.hbm.xml" />
</session-factory>
</hibernate-configuration>
请问 我映射关系错了么？ Hibernate 关系映射
[解决办法]
spring里的配置呢？目测你的testService这个没配置好。
[解决办法]
解析Role.hbm.xml出错，看看是不是大小写，外键名关联错误
