Class TemplateRedirect

java.lang.Object

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

public class TemplateRedirect
extends java.lang.Object

Performs redirection of template request into rest context. Note that even if no special rest mapped for template, but request looks like direct file template, it would be rendered with the DirectTemplateExceptionMapper.

Rest resource convention: /[rest context]/[prefix]/[path from request], where [prefix] is application registration name by default (but may be configured). Additional mappings may be configured to sub url, so redirection to different rest "branches" may be performed, depending on called url.

If resource is annotated with Template annotation (it should!) then TemplateAnnotationFilter will detect it and set specified template into context TemplateContext.

Important: resources must use TemplateView as base template model class in order to properly support Template annotation.
