Jackson JSON : Subclass fields not seralized if implements java.util.Set -

-

i have following inheritance

interface resultset extends java.util.set<customresult> {     public int getcount(); }  @xmlaccessortype(xmlaccesstype.none) @xmltype(name = "customresultset") class customresultset extends linkedhashset<customresult> implements resultset {      @xmlelement(name = "count")     private int count;      public void setcount(int count) {        this.count = count     }  } . . public static void main() { objectmapper objectmapper = new objectmapper(); objectmapper.disable(deserializationfeature.fail_on_unknown_properties); objectmapper.disable(serializationfeature.fail_on_empty_beans); customresultset customresultset = new customresultset(); customresult customresult = new customresult(55, "abc"); customresultset.setcount(11); customresultset.add(customresult); system.out.println(objectmapper.writevalueasstring(customresultset));  }

with above code serializes values in collection customresultset not field count in customresultset .

anything implements set interface treated set jackson , result in json array, if put annotations on custom class. best shot have custom serializer class.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
