java - @Async not working for me

Question

I am using @Scheduled and it have been working fine, but can't get the @Async working. I tested it many times, and seems that it is making my method asynchronous. Is there any other thing, configuration, or parameter I am missing? I have one class that has two methods one, the method marked with @Scheduled, executes and calls the second one which has been marked with @Async.

Here is my config:

<!-- Scans within the base package of the application for @Components to configure as beans -->
<context:component-scan base-package="com.socialmeety" />
<context:annotation-config />
<tx:annotation-driven transaction-manager="transactionManager" />
<task:annotation-driven/>

<!-- Configures support for @Controllers -->
<mvc:annotation-driven />

<!-- Resolves view names to protected .jsp resources within the /WEB-INF/views directory -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
    <property name="prefix" value="/WEB-INF/views/"/>
    <property name="suffix" value=".jsp"/>
</bean>

<dwr:configuration />
<dwr:annotation-config />
<dwr:url-mapping />
<dwr:controller id="dwrController" debug="true" />

<bean class="org.springframework.web.servlet.mvc.SimpleControllerHandlerAdapter" />

Thanks.

As you're calling your @Async method from another method in the same object, you're probably bypassing the async proxy code and just calling your plain method, ie within the same thread.

One way of solving this is by making sure your call to the @Async method is from another object. See comments at end of this article: http://groovyjavathoughts.blogspot.com/2010/01/asynchronous-code-with-spring-3-simple.html

But it gets messy doing things like that, so you could just autowire the TaskScheduler, wrap up your method in a Runnable and execute it yourself.
