lookup for a known key-value pair in jsf

I have an integer field in the bean I use in my JSF application. The integer field is showing the status of the process and it can be 0, 1 or 2. What I'd like to do is either automatically map this value to the corresponding String representation (0- not processed yet, 1- being processed ...etc) or do this in a hard-coded way using jsf. I don't prefer to handle it in another way because the main jsf bean I use contains several hibernate models and it'll get complicated 开发者_JAVA技巧if I opt another way. Thanks for the help!

Several ways.

1. Use rendered attribute.

   <h:outputText value="Not processed" rendered="#{bean.status == 0}" />
   <h:outputText value="Being processed" rendered="#{bean.status == 1}" />
   <h:outputText value="Finished processing" rendered="#{bean.status == 2}" />
   

2. Use conditional operator ?: in EL.

   <h:outputText value="#{bean.status == 0 ? 'Not Processed' : bean.status == 1 ? 'Being processed' : 'Finished processing'}" />
   

3. Use an application-wide Map<Integer, String> somewhere.

   public class Bean {
       private static Map<Integer, String> statuses = new HashMap<Integer, String>();
       static {
           statuses.put(0, "Not processed");
           statuses.put(1, "Being processed");
           statuses.put(2, "Finished processing");
       }
       // Add getter.
   }
   

   with

   <h:outputText value="#{bean.statuses[bean.status]}" />
   

   which does basically bean.getStatuses().get(bean.getStatus()).

I would suggest you to go for i18n.

your property file should look like.

message_en.properties

process_in_progress=Process is under prgress
process_failed=Process failed to execute.
