jpa - Named Query to return a List<String> -


hello using dropwizard application.

the resource class

@path("/people") @produces(mediatype.application_json) public class peopleresource{      private persondao pdao;      public peopleresource(persondao pdao) {         this.pdao = pdao;     }      @get     @timed     @unitofwork     public list<string> getallpeople() {         return pdao.findall();     } } 

the dao class

public class persondao extends abstractdao<person> {  public persondao(sessionfactory factory) {     super(factory); }  public list<string> findall() {     return list(namedquery("com.example.findall")); }  public person create(person p) {     return persist(p);  } 

the person class

@jsonignoreproperties(ignoreunknown = true) @entity @table(name = "person")  @namedqueries({     @namedquery(              name = "com.example.findall",             query = "select distinct p.name person p"     ) })  @jsonproperty string name; 

but when try access resource fails saying in dao class method 'findall' should return list<person> instead of list<string>. missing? checked query teh database , returns correct result. tehre way configure return type of query inside namedquery?

try removing list generic so:

public list findall() {   return list(namedquery("com.example.findall")); } 

it seems cast list of strings , can use generics further chain.
