Issue with making a controller method asynchronous with Spring 3.2.RC2...

[balteo]

Hello,

I am trying to test the latest asynchronous feature of Spring MVC controllers but I have not been able to get it to work.

Here is the code for my async method:

@RequestMapping(value = "/hello")
	public Callable<String> async(final Model model) {
		System.out.println("entered async controller method");
		return new Callable<String>() {
			public String call() throws Exception {
				Thread.sleep(2000L);
				model.addAttribute("message", "asyncRequest dealt with");
				System.out.println("about to return from call()");
				return "hello";
			}
		};
}

Here is the relevant portion from web.xml:

	<servlet>
		<servlet-name>SpringMVC</servlet-name>
		<servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
		<init-param>
			<param-name>contextConfigLocation</param-name>
			<param-value>/WEB-INF/spring/webmvc-config.xml</param-value>
		</init-param>
		<load-on-startup>1</load-on-startup>
		<async-supported>true</async-supported>
	</servlet>

However "about to return from call()" is never printed in the console and I never get to see such logs as this: 08:25:17 [MvcAsync1] WebAsyncManager - ...
in the console...

FYI, I use Spring 3.2.RC2

Can anyone please help?

Regards,

Julien.

I finally found why my sample was not working: one has to add the following to the web-mvc configuration file:

<mvc:annotation-driven>
	<mvc:async-support default-timeout="3000"/>
</mvc:annotation-driven>
