C#与工业设备的OPC DA/UA协议通信开发摘要：本文介绍了C#与工业设备通信的两种OPC协议（OPC DA和OPC UA）的实现方法。OPC DA基于COM/DCOM技术，适用于Windows平台，提供实时数据采集功能；OPC UA则支持跨平台通信，具备更强的安全性和数据建模能力。文章详细展示了如何使用C#通过OPC DA和OPC UA协议读取、写入数据，并提供了代码示例，包括安装相关库、建立连接、订阅数据变化等关键步骤。这些方法为工业自动化中的设备监控与控制提供了实用解决方案。（149字）阅读详情

看错了，你的map貌似没加载成功，看看hibernate.cfg.xml这个吧
……

我仔细找了一下原来是com.struts2.service下的接口的实现方法没有继承HibernateDaoSupport，
并且我指定了 <aop:config>
<aop:advisor pointcut="execution(* com.struts2.service.*.*(..))" advice-ref="txAdvice"/>
</aop:config>
下的所有接口参与事务
而我在bean中愣是 <bean id="loginService" class="com.struts2.service.impl.LoginServiceImpl">
<property name="sessionFactory" ref="sessionFactory"></property>
</bean>
把业务逻辑交给Spring管理，所以报错~！

An association from the table t_person refers to an unmapped class: int

很明显一个表字段映射错误了吧

Cannot resolve reference to bean 'transactionManager' while setting bean property 'transactionManager'

不是说你配置通知器的时候没注入事务管理器么？
