I've enabled EL support for the authz tag. We pull
content items from a CMS for display. The content
items will have ifAllGranted, ifAnyGranted, and
ifNotGranted attributes which with EL we can pull at
runtime from the content item into the authz tags.
Below is the code. What do you all think of it?
TIA,
Scott
...
import
org.springframework.web.util.ExpressionEvaluationUtils;
...
public class AuthorizeTag extends TagSupport {
...
public int doStartTag() throws JspException {
if (((null == ifAllGranted) ||
"".equals(ifAllGranted))
&& ((null == ifAnyGranted) ||
"".equals(ifAnyGranted))
&& ((null == ifNotGranted) ||
"".equals(ifNotGranted))) {
return Tag.SKIP_BODY;
}
ifAllGranted =
ExpressionEvaluationUtils.evaluateString("ifAllGranted",
ifAllGranted, pageContext);
ifAnyGranted =
ExpressionEvaluationUtils.evaluateString("ifAnyGranted",
ifAnyGranted, pageContext);
ifNotGranted =
ExpressionEvaluationUtils.evaluateString("ifNotGranted",
ifNotGranted, pageContext);
