Class ErrorRedirect

java.lang.Object

ru.vyarus.guicey.gsp.app.filter.redirect.ErrorRedirect

public class ErrorRedirect
extends java.lang.Object

Redirects response error to the configured error page (ServerPagesAppBundle.AppBuilder.errorPage(String)). Only response codes >= 400 (errors) are handled, everything else considered as normal flow.

When SPA support is enabled, also intercept all 404 errors and checks if it could be SPA route (and do home redirect instead of error).

Asset errors are intercepted directly inside ServerPagesFilter. Rest errors are intercepted with TemplateExceptionListener and TemplateErrorResponseFilter.
