How can I redirect in JSF 2.0
I want to redirect from a link in a JSF page, how can I do it?
In HTML I can use <a>
tag for this. But in JSF I use <h:outputLink>
or <h:commandLink>
as they can be conditionally rendered. I want redirect link to other page in same application or to an external URL. How can I do it with JSF? How can I use action
in <h:c开发者_运维技巧ommandLink>
for this?
Assuming that you'd like to redirect to some.xhtml
which is placed in web root folder:
You can just continue using plain HTML.
<a href="#{request.contextPath}/some.xhtml">go to some page</a>
For conditional rendering, just wrap it in an
<ui:fragment>
.
Or use
<h:link>
with implicit navigation.<h:link outcome="/some" value="go to some page" />
Note: no need to prepend context path nor to include
FacesServlet
mapping.
Or use
<h:commandLink>
with?faces-redirect=true
.<h:commandLink action="/some?faces-redirect=true" value="go to some page" />
Note: no need to prepend context path nor to include
FacesServlet
mapping.
Or use
<h:outputLink>
, but you need to specify context path.<h:outputLink value="#{request.contextPath}/some.xhtml" value="go to some page" />
Redirecting to an external URL is already answered in this duplicate: Redirect to external URL in JSF.
