RequestContextHolder

:: spring API for setting the values to any of three scopes request, session or global session.

  we can simply use RequestContextHolder to get the request attributes and set the values.

 

 

• currentRequestAttributes() – Return the RequestAttributes currently bound to the thread.
• getRequestAttributes() – Return the RequestAttributes currently bound to the thread.
• resetRequestAttributes() – Reset the RequestAttributes for the current thread.
• setRequestAttributes(RequestAttributes attributes) – Bind the given RequestAttributes to the current thread, not exposing it as inheritable for child threads.
• setRequestAttributes(RequestAttributes attributes, boolean inheritable) – Bind the given RequestAttributes to the current thread.

# currentrequestattributes() vs getrequestattributes

 

currentRequestAttributes

 == getrequestattributes + checks request is in a JSF environment + if so it returns FacesContext parameters

 

 

HttpServletRequest request 
	= ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes())
    		.getRequest();

 

HttpSession session 
	= ((ServletRequestAttributes)RequestContextHolder.currentRequestAttributes())
    		.getRequest()
       		.getSession();
