Spring@Transactional不创建事务

我正在用弹簧把我的头撞到墙上。我已经搜索了好几天试图让@Transactional开始工作。任何帮助都将不胜感激

我使用Spring3.2作为访问MySQL数据库的web应用程序（我使用SpringMVC、JDBC和安全性）。mysql表正在使用InnoDB。我正在努力让声明性事务正常工作（我尝试使用编程事务，并且成功地工作了）。我有控制器调用带有@Transactional注释的服务方法。控制器在servlet xml文件中配置，服务/dao在单独的应用程序xml文件中配置。我似乎找不到@Transactional的正确配置，无法拾取并创建事务。没有错误-只是没有事务处理。以下是我的设置的详细信息：

使用DispatcherServlet的Web应用程序，使用带注释的控制器配置servlet XML文件。控制器注入了服务接口

服务方法使用@Transactional和注入调用的DAO类进行注释

服务类用@Named注释，应用程序配置为使用组件扫描在spring-app-context.xml中获取这些服务类

事务处理配置在spring-app-context.xml中设置（不在servlet配置文件中）

web.xml：

<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>
    /WEB-INF/config/spring-app-context.xml
    /WEB-INF/config/spring-security-context.xml
  </param-value>
</context-param>

<listener>
  <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<servlet>
  <servlet-name>appServlet</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <init-param>
    <param-name>contextConfigLocation</param-name>
    <param-value>/WEB-INF/config/spring-servlet-context.xml</param-value>
  </init-param>
  <load-on-startup>1</load-on-startup>
</servlet>


<servlet-mapping>
  <servlet-name>appServlet</servlet-name>
  <url-pattern>/</url-pattern>
</servlet-mapping>

你说的“没有交易”是什么意思？你如何诊断代码不是事务性的？你是否会因为不在事务中而得到任何异常？？嘿，JB Nizet-我可以通过日志和数据在数据库中的显示方式来诊断它。使用编程事务时，日志会非常清楚地显示DataSourceTransactionManager日志条目-@Transactional不会。我还向代码中添加了一个有意的异常来测试它，并且数据库中的条目没有回滚。shazintlc-不幸的是，没有，我没有收到任何异常。您的类路径中是否有

spring aspects
