Question

我有一个Spring 3.2.8应用程序，其中我有一个特殊情况，我希望在Context Listener中启动一个事务。

我知道并且意识到侦听器不是Spring托管bean，所以我不完全确定如何将我的方法标记为@Transactional。我已经尝试将bean标记为@Configurable，但这似乎不起作用;我猜b / c应用程序服务器在加载spring上下文之前实例化这个bean。

我已使用TransactionAspectSupport.currentTransactionStatus()检查了交易状态，但是当没有托管开放交易时，我会收到NoTransactionException抛出。

Spring中是否有任何内容允许我将此方法标记为事务的一部分？

@Configurable
public class PatchEngineContextListener implements ServletContextListener{

    // SLF4J logger
    private static final Logger logger = LoggerFactory.getLogger(PatchEngineContextListener.class);


    // HELPERS
    private ApplicationContext appContext;
    @Autowired private PatchService patchService;
    @Autowired private PatchEngine patchEngine;

    @Override
    @Transactional
    public void contextInitialized(ServletContextEvent sce) {

        // get the app context
        appContext = WebApplicationContextUtils.getWebApplicationContext(sce.getServletContext());
        appContext.getAutowireCapableBeanFactory().autowireBean(this);

        logger.info( TransactionAspectSupport.currentTransactionStatus().toString() );

        try {
            setPatchEngineUser();
            patchEngine.execute();
            clearPatchEngineUser();
        } catch (Exception e) {
            throw new RuntimeException(e);
        }
    }
}

Web.xml中：

<!-- Creates the Spring Container shared by all Servlets and Filters -->
<listener>
    <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

<!-- Patch Engine launched after spring finishes setting up its context -->
<listener>
    <listener-class>com.ia.system.patch.engine.PatchEngineContextListener</listener-class>
</listener>

的applicationContext.xml：

<context:spring-configured/>

如何在非spring管理的bean中启动事务？
