Spring：没有Hibernate Session绑定到线程，配置不允许在这里创建非事务性的

时间：2014-05-31 19:55:00

标签： java spring hibernate spring-mvc

我正在创建简单的Web应用程序来显示和添加行到我的oracle数据库（Regions表）。可悲的是，我在标题中得到例外。我见过与此相关的类似问题，遗憾的是没有任何帮助。

我做错了什么？我知道这与交易有关。我已将服务注释为@Transactional，但它并未解决我的问题。

如果有人可以在imports中检查Service是否正确。

如果需要更多内容，请发表评论。

3 个答案:

答案 0 :(得分：2)

从dispatcher-servlet.xml

移动此代码 
<beans:bean id="regionsDao" class="facade.RegionsDaoImpl"/>

<beans:bean id="regionService" class="facade.RegionServiceImpl"/>

到applicationContext.xml：

<bean id="regionsDao" class="facade.RegionsDaoImpl"/>

对于RegionServiceImpl，您不需要<bean/>，因为您的服务impl类上有@Service。在applicationContext.xml添加

<context:component-scan base-package="facade" />

在RegionServiceImpl课程中，导入应该是：

import org.springframework.transaction.annotation.Transactional;

答案 1 :(得分：0)

我的猜测是你的@Transactional服务没有被Spring AOP系统正确检测。这可以通过在事务方法中放置断点并检查调用堆栈来验证。 Spring使用CGLIB生成代理类，所以如果一切正常，你应该看到一些不寻常的类名（寻找＆＃34; $ EnhancerByCGLIB＆＃34;）

答案 2 :(得分：0)

在服务对象中，您导入了错误的事务注释。你正在使用的是java native（EJB），第一个是： org.springframework.transaction.annotation.Transactional

所以，只需更改此行

即可

导入javax.transaction.transactional

与

import org.springframework.transaction.annotation.Transactional

RegionServiceImpl中的

。
