java - REST - mark entries read/unread -

i did simple resp app entering blog entries html page, here sample code.. ideas why? googles looks should ok.. showing did.. every entry has id, saved in arraylist , has simple attribute text.. wanna add special commands later, can add event in command line well.. wanna add function can mark read/unread, default unread.. ideas how that?

thanks

@path("/") public class rootresource { private final entrylistresource entries = new entrylistresource();  @get @path("favicon.ico") public response getfavicon() {     return response.nocontent().build(); }  @get public response get(@context uriinfo uriinfo) {     final uri location = uriinfo.getabsolutepathbuilder().path("/entries").build();     return response.seeother(location).build(); }  @path("entries") public entrylistresource getentries() {     return entries; } } 

and

@xmlrootelement(name = "entryref") public class entryresourceref { private int id; private uri href;  @xmlattribute public uri gethref() {     return href; }  @xmlattribute public int getid() {     return id; }  public void setid(int id) {     this.id = id; }  public void sethref(uri href) {     this.href = href; } } 

finally

@xmlrootelement(name = "entry") @xmlaccessortype(xmlaccesstype.none) public class entryresource { private int id; private string text;   @get @produces(mediatype.application_xml) public response get() {     return response.ok(this).build(); }  @get @produces(mediatype.text_html) public response gethtml(@context uriinfo uriinfo) {     final stringbuilder sb = new stringbuilder();  @put @consumes(mediatype.text_plain) public response updateplain(string text,string description, @context uriinfo uriinfo) {     return update(text, description, uriinfo.getabsolutepath()); }  @put @consumes(mediatype.application_form_urlencoded) public response updateasform(@formparam("text") string text, @formparam("description") string description,@context uriinfo uriinfo) {     return update(description,text, uriinfo.getabsolutepath()); }  private response update(string text,string description, uri self) {     if (gettext().equals(text)) {         throw new webapplicationexception(                                           response                                           .status(response.status.conflict)                                           .entity("the blog entry text has not been modified")                                           .type(mediatype.text_plain)                                           .build()                                           );     }     settext(text);     return response.seeother(self).build(); } 

sources

@xmlrootelement(name = "entries") @xmlaccessortype(xmlaccesstype.none) public class entrylistresource {  private final atomicinteger nextentryid = new atomicinteger(0); private uriinfo uriinfo = null;   @get @produces(mediatype.application_xml) public response get() {     return response.ok(this).cachecontrol(cc).build(); }  @xmlelement(name = "blog") public collection<entryresourceref> getentries() {     final collection<entryresourceref> refs = new arraylist<entryresourceref>();     (final entryresource entry : entries.values()) {         final entryresourceref ref = new entryresourceref();         ref.setid(entry.getid());         ref.sethref(getentryuri(entry));         refs.add(ref);     }     return refs; } 

you may use 0 , 1 sort results.

while fetching records may append "read" or "unread" in query itself. example given below

select news.*,  (case news.status when 0 'unread'  when 1 'read'  end) status news news 

this native sql or can in hql well.

other solution can may take enum in news entity. can string shown in ui , in db save ordinal value i.e. 0 or 1. example code given below.

@table(name = "new") public class new  {     private newsstatus newsstatus; }   public static enum newsstatus {     read{         public string tostring(){             return "read";         }     },      unread{         public string tostring(){             return "unread";         }     }     public int getvalue(){         return this.ordinal() + 1;     }     public string getlabel(){         return this.tostring();     }     public static newsstatus getbylabel(string label)      {         if(label == null)             return null;         for(newsstatus ns : newsstatus.values()) {             if(label.equalsignorecase(ns.getlabel()))                 return ns;         }         return null;     }     public static newsstatus getbyvalue(int value){         return newsstatus.values()[value-1];     } } 

do let me know if further details required?
