测试：
public class PermissionTest {
public static void main(String[] args) {
ApplicationContext act=new FileSystemXmlApplicationContext("classpath:cn/com/myweb/spring/applicationContext.xml");
IUserInfoBiz userInfoBiz=(IUserInfoBiz) act.getBean("userInfoBiz");
List users=userInfoBiz.userInfoList();
System.err.println(users.size());
System.err.println(users.get(0).getRole().getRights().size());
}
}

hb.xml文件:
userinfo：

    <many-to-one name="role" class="SysRole" fetch="select" lazy="false">
        <column name="roleID" not-null="true"></column>
    </many-to-one>
 </class>

SysRole:

    <!-- 
     -->
    <bag name="rights" inverse="true" table="sys_role_right">
        <key>
            <column name="roleID" not-null="true"/>
        </key>
        <many-to-many entity-name="cn.com.obj.model.po.std.SysRight">
            <column name="rightID" not-null="true"></column>
        </many-to-many>
    </bag>

    <bag name="users" inverse="true">
        <key>
            <column name="roleID" not-null="true"></column>
        </key>
        <one-to-many class="UserInfo"/>
    </bag>
 </class>
