SSH整合
最近刚学SSH整合 struts2.3.14 hibernate4.3 spring3.2.2
以下是使用sessionFactory.getCurrentSession().save(emp)错误提示 但是使用opensession（）不会出错
Exception in thread "main" org.hibernate.HibernateException: save is not valid without active transaction
at org.hibernate.context.internal.ThreadLocalSessionContext$TransactionProtectionWrapper.invoke(ThreadLocalSessionContext.java:348)
at com.sun.proxy.$Proxy8.save(Unknown Source)
at com.zhj.service.imp.EmployeeService.addEmployee(EmployeeService.java:23)
at com.zhj.test.MainTest.main(MainTest.java:50)
以下是配置文件

还有一个问题 spring的jar包里是不是已经自动解决了懒加载的问题啊 我没配什么 也没写别的代码 懒加载没影响啊 SSH Spring
[解决办法]
就是要引入TransactionManager，并将你的addEmployee方法置于事务控制之下再试试
[解决办法]
<!-- 设置事务的传播特性 -->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<tx:method name="get*" propagation="NOT_SUPPORTED"
read-only="true" />
<tx:method name="*" propagation="REQUIRED" />
</tx:attributes>
</tx:advice>
<aop:config proxy-target-class="true">
<aop:advisor
pointcut="execution(* com.bysee.ssh2.service.*.*(..))"
advice-ref="txAdvice" />
</aop:config>
类似于这样写
