Spring cron job not working

Question

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

I defined a service class as:

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:

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

spring-servlet.xml:

<?xml  version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/beans 
    http://www.springframework.org/schema/beans/spring-beans.xsd

    http://www.springframework.org/schema/task 
    http://www.springframework.org/schema/task/spring-task-3.0.xsd">

<context:annotation-config />

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

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <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/spring-servlet.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>
</web-app>

Exception:

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?

Solution 1

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

Solution 2

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

You appear to be loading the same XML file twice. Once should do (if you remove the ContextLoaderListener).

If I try to add: <task:annotation-driven /> , I receive an exception, because in XML is written <context:annotation-config /> . If I delete <task:annotation-drive />, I don't receive error.

That doesn't make much sense. Can you show the exception. BTW, there's no need to reply the same way to more than one answer (even if they are the same) - we can all read all the comments.
