JSF el中使用enum

JSF el中使用enum

参见

If you have the enum
public enum Status {
    YES, NO
}

you can reference the enums in your jsf pages like so:
<h:outputText value="text" rendered="#{myBean.status == 'YES'}"/>

I'm not so sure about the String evaluation, due to something I stumbled upon while refactoring some code to use enums: if you have a typo in your status String, ie:
<h:outputText value="text" rendered="#{myBean.status == 'YESSIR'}"/>

you will actually get a runtime error when you hit the page because the EL parser will try to coerce 'YESSIR' into a Status enum and fail.
