Java Spring cron 作业不起作用

Spring cron job not working

提问by xsiraul

I am newbie with Spring framework. At the moment I try to integrate cron job service.

我是 Spring 框架的新手。目前我尝试集成 cron 作业服务。

I defined a service class as:

我将一个服务类定义为：

package com.test.cron;
@Service
public class CronJob {
    protected static final Logger logger = Logger.getLogger(PasswordRemindFlusher.class);

    @Scheduled(cron="0 0/2 * * * ?")
    public void demoServiceMethod()
    {

        logger.debug("Cron job started.");
    }
}

Then I defined in servlet config:

然后我在servlet配置中定义：

<context:component-scan base-package="com.test.cron" />

spring-servlet.xml:

弹簧servlet.xml：

Exception:

例外：

SEVERE: Exception sending context destroyed event to listener instance of class org.springframework.web.context.ContextLoaderListener
java.lang.IllegalStateException: BeanFactory not initialized or already closed - call 'refresh' before accessing beans via the ApplicationContext
    at org.springframework.context.support.AbstractRefreshableApplicationContext.getBeanFactory(AbstractRefreshableApplicationContext.java:172)

All other controllers in the same package works. I use Spring 3.1.2 framework. May I missed something?

同一个包中的所有其他控制器都可以工作。我使用 Spring 3.1.2 框架。我可能错过了什么吗？

You will need to add few things in your xml namespace and schema location. See thisguide.

您需要在 xml 命名空间和架构位置中添加一些内容。请参阅本指南。

Did you @EnableScheduling(or the Xml equivalent)? See this guidefor more detail.

你@EnableScheduling（或Xml等价物）吗？有关更多详细信息，请参阅本指南。
