Spring Security Child Thread Context

Question

Hi everyone,

So I'm working on this Spring MVC application using Spring Security. I've been hitting a performance problem in some instances where my controller is taking way too long to respond. This is due to a processing method that can take a huge amount of data in to process, based on some user input.

Now I've been tweaking the code a bit in and around that processing method with my team and I don't think we can get much better performance out of that without slicing it and executing each slice asynchronously.

The problem is when I try to slice it and distribute the work to child threads, using a threadpool from java.util.concurrent, I get error messages about the security context when those execute.

Here is an extract of the stacktrace:

I know it's not good practice to spawn threads from a request... but we've ran out of ideas at this point and each worker thread shouldn't take more than a handful of seconds by our measurements. Also it is expected that this feature is going to be used by 1 or 2 dedicated users once a week only.

Is there a way to pass the securityContext to the child threads or anything similar that would allow those threads to execute?

Thanks

Answer 1

We usually do the following: In the initial spring-managed thread do

Locale locale = LocaleContextHolder.getLocale();
RequestAttributes ra = RequestContextHolder.getRequestAttributes();

Now you need to put those two values somewhere your new thread can find them. Then you do:

 LocaleContextHolder.setLocale( locale, true);
 RequestContextHolder.setRequestAttributes( ra, true);

In your new thread. Although I'm not sure if this is the supported method, it's always worked well.

Answer 2

Maybe you could use something like InheritableThreadLocalSecurityContextHolderStrategy ? I think what it does is to copy the security context of the current thread to any threads you create within
