Equivalent to the deprecated <sec:authorize> ifNotGranted attribute

问题

I would like to prevent an image having a link if a user does NOT have a certain role. e.g.

<sec:authorize ifNotGranted="ROLE_ACCOUNTS" ><img src="someimage.jpg"/></sec:authorize>
<sec:authorize ifAllGranted="ROLE_ACCOUNTS" ><a href="somelink.htm"><img src="someimage.jpg"/></a></sec:authorize>

However ifNotGranted and ifAllGranted are now deprecated in favour of the access expression. I can see that ifAllGranted can be replicated with:

<sec:authorize access="hasRole('ROLE_ACCOUNTS')"><a href="somelink.htm"><img src="someimage.jpg"/></a></sec:authorize>

But how can ifNotGranted be replicated using the access method? Any help would be greatfully appreciated.

回答1:

SpEL expression can be negated with ! operator:

<sec:authorize access="!hasRole('ROLE_ACCOUNTS')">...</sec:authorize>

回答2:

In case if you have many files to update, I recommend use the regular express to search and replace

find

<sec:authorize\s+ifAnyGranted="([^"]+)"

replace with

<sec:authorize access="hasAnyRole('$1')"

and search

<sec:authorize\s+ifNotGranted="([^"]+)"

replace with

<sec:authorize access="!hasAnyRole('$1')"

Hope this can save you time
