Spring Special Code
Set flow and menu item mapping
Once Request filter
Get session attributes
public void setLocationMaps(MenuComponent[] menuComponents) {
for (MenuComponent menuComponent: menuComponents) {
if (null == this.locationMapping.get(menuComponent.getLocation())
|| null != menuComponent.getParent()) {
this.locationMapping.put(menuComponent.getLocation(), menuComponent);
}
if (menuComponent.getMenuComponents().length > 0) {
this.setLocationMaps(menuComponent.getMenuComponents());
}
}
}
Once Request filter
public class MenuFilter extends OncePerRequestFilter {
/**
* This method looks for a "locale" request parameter. If it finds one, it sets it as the preferred locale
* and also configures it to work with JSTL.
*
* @param request the current request
* @param response the current response
* @param chain the chain
* @throws IOException when something goes wrong
* @throws ServletException when a communication failure happens
*/
@SuppressWarnings("unchecked")
public void doFilterInternal(HttpServletRequest request, HttpServletResponse response,
FilterChain chain)
throws IOException, ServletException {
chain.doFilter(request, response);
// Reset thread-bound LocaleContext.
LocaleContextHolder.setLocaleContext(null);
}
}
Flow Execution listener and external context
public class MenuFlowLister extends FlowExecutionListenerAdapter {
public void requestProcessed(RequestContext context) {
String id = context.getActiveFlow().getId();
MenuRepository menus = (MenuRepository) context.getExternalContext().getApplicationMap()
.get(MenuRepository.MENU_REPOSITORY_KEY);
}
}
Get session attributes
Object mutex = RequestContextHolder.currentRequestAttributes().getSessionMutex();
RequestAttributes attributes = RequestContextHolder.currentRequestAttributes();
String test;
synchronized (mutex) {
test = (String)attributes.getAttribute("zenius", RequestAttributes.SCOPE_SESSION);
}
return test;
