java - adding second level data in properties file -

what have properties file below.

welcome.properties

admin = admin welcomeadmin = welcome admin editadmin = edit admin 

as have repeated admin word, want use below.

admin = admin welcomeadmin = welcome #{admin} editadmin = edit #{admin} 

so if change @ 1 place i.e. @ admin = admin, places reflect.

any idea/ suggestion how done appreciated.

as per today, classic resourcebundle class doesn't support named parameters , substitution, rather supports simple placeholders of {0} type in key-value pairs of bundles, substituted using messageformat#format.

in light if replace welcome #{admin} welcome {0} you'd able achieve functionality seek using 1 of following:

1. jsf's <h:outputformat>:

   <h:outputformat value="#{msg.welcomeadmin}">     <f:param value="#{msg.admin}" /> </h:outputformat> 

2. jstl's <fmt:message>:

   <fmt:message key="msg.welcomeadmin">     <fmt:param value="#{msg.admin}"> </fmt:message> 

you create own el function, or tag handler, or ui component, or make use of messageformat class methods in beans, etc. of course, extend resourcebundle class support named parameters , return message named parameters parsed.

suggested reading:

1. do resource bundles in java support runtime string substitution?;
2. how use parameterized messageformat non-value attributes of jsf components;
3. pass parameters messages resource bundle components other h:outputformat.
