Spring Boot配置HttpSessionListener和HttpSessionAttributeListener无效。

Question

我有一个spring boot (v1.5.9.RELEASE)项目，想要实现session的管理，实现了HttpSessionListener和HttpSessionAttributeListener这两个接口，在MySessionListener中使用@WebListener注解，在启动类中使用@SpringBootApplication注解
但是经过测试，访问网页（ftl页面）无法触发sessionCreated()方法；用户登陆时调用request.getSession().setAttribute()或者session().setAttribute()都无法触发attributeAdded()方法。请问有人知道这是为什么吗代码如下：

重发一下代码部分DemoApplication.java    @SpringBootApplication
    @ServletComponentScan
    public class DemoApplication {
            public static void main(String[] args) {
                    SpringApplication.run(DemoApplication.class, args);
            }
    }MySessionListener.java    @WebListener
    public class MySessionListener implements HttpSessionListener, HttpSessionAttributeListener {
        private final static Log log = LogFactory.getLog(MySessionListener.class);
        @Override
        public void sessionCreated(HttpSessionEvent se) {
            log.info("sessionCreated-----" + se.getSession().getId());
        }
        @Override
        public void sessionDestroyed(HttpSessionEvent se) {
            log.info("sessionDestroyed-----" + se.getSession().getId());
        }
        @Override
        public void attributeAdded(HttpSessionBindingEvent se) {
            log.info("attributeAdded: "+se.getSession().getId());
        }
        @Override
        public void attributeRemoved(HttpSessionBindingEvent se) {
            log.info("attributeRemoved: "+se.getSession().getId());
        }
        @Override
        public void attributeReplaced(HttpSessionBindingEvent se) {
            log.info("attributeReplaced: "+se.getSession().getId());
        }
    }

MySessionListener需要注册吧，
 @Bean
    public ServletRegistrationBean indexServletRegistration() {
        ServletRegistrationBean registration = new ServletRegistrationBean(new ClassName());
        registration.addUrlMappings("/XXX");
        return registration;
    }
