HttpSessionListener中的事务提交不会持久保存到DB

时间：2013-04-18 15:00:09

标签： java spring tomcat jta

我最近开始使用JBossTM以便在多个数据库连接上使用JTA，这非常成功。如果我尝试从任何控制器执行事务，它可以正常工作。

但是，我最近开始尝试从HttpSessionListener的实例中保留实体，以便我可以跟踪用户会话，但我无法使持久性工作。我确信这里有一些非常简单的东西，但我会非常欢迎任何提示。

问题在于，虽然一切似乎都运行正常（日志明智）但实际上并没有提交到数据库。我在尝试持久化到没有事务管理器的数据库之前看到过这个错误（在我切换到JBossTM之前），但似乎无法解决这个问题。

以下是我的application-context.xml的相关部分：

SessionListener.java 

public class SessionListener implements HttpSessionListener {
    private static Log log = LogFactory.getLog(SessionListener.class);

    @Override
    @Transactional
    public void sessionCreated(HttpSessionEvent event) {
        getDAO(event).save(new Session(event.getSession().getId(),Calendar.getInstance()));
    }

    @Override
    public void sessionDestroyed(HttpSessionEvent event) {
        ....
    }   

    private SessionDAO getDAO(HttpSessionEvent event){
        HttpSession session = event.getSession();

        ApplicationContext ctx = 
            WebApplicationContextUtils.
                  getWebApplicationContext(session.getServletContext());

        SessionDAO dao = 
                      (SessionDAO) ctx.getBean("sessionDAO");

        return dao;
    }
}

对于现在发现这一点的人，我最终直接进入数据源并运行插入查询。

@Override
@Transactional
public void sessionCreated(HttpSessionEvent event) {
    log.trace("sessionCreated(): "+event.getSession().getId());

    JdbcTemplate select = new JdbcTemplate(getDS(event));
    SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
    String datetime = sdf.format(Calendar.getInstance().getTime());

    select.update("INSERT INTO sessions (username, session, started) VALUES ('','"+event.getSession().getId()+"','"+datetime+"')");
}
private DataSource getDS(HttpSessionEvent event){
    HttpSession session = event.getSession();

    ApplicationContext ctx = 
        WebApplicationContextUtils.
              getWebApplicationContext(session.getServletContext());

    DataSource dao = 
                  (DataSource) ctx.getBean("BPSCoreDS");

    return dao;
}
