playframework - How to use Http.Context.current() in a Promise in Play? -


In Play Framework 2.2.2, I want to return the promise. However, I'm calling a function which is called hp.contex. (Access needed variables currently logged in , JPA connection ...).

Of course, because the promise is executed in another thread, he does not have access to Http.Context.current () . Can I preserve it in the word, or should I manually restore it? Should I Use Another Pattern?

Example: 

  Public stable promise & lt; Results & gt; GetAvailableServices () {Return the new operation. Launch (new function 0 & lt; result & gt; () {@ Override public results apply) Throwshell {// Long Operation List & lt; Services & gt; data = buildResult (); // template // template // header for htp.context.current (). Args.get ("usermodel") returns the results. Need access (services_template.render (services));}}); }    
 
 
 Yes,  is the HTTPProduction Contex  that you need.  
 When someone is made to  HttpExecutionContext , when used for later code execution of  HttpExecutionContext .  
 Therefore, they should campaign properly in the  Http.Context  threads.  
 Your example code should work fine, for example. However, you need to make sure that when you  call   getAvailableServices , it is available in the  HTP.Contax  thread that is calling from you Are there. If you are not  htp.context  while calling the method, then  httpexunecontax  code  from that code. Contex will be unable to capture the thread and promote it when the promise  Function0  is implemented.
