java - Jackson unrecognized field for class name -

following how json string looks

{     "employee": {         "id": "c1654935-2602-4a0d-ad0f-ca1d514a8a5d",         "name": "smith"         ...     } } 

now using objectmapper#readvalue(jsonasstr,employee.class) convert json. employee class follows...

@xmlrootelement(name="employee") public class employee implements serializable {     private string id;     private string name;     ...      public employee() {     }      @xmlelement(name="id")     public string getid() {         return id;     }      public void setid(string id) {         this.id= id;     }      @xmlelement(name="name")     public string getname() {         return name;     }      public void setname(string name) {         this.name = name;     }     ... } 

the exception getting

com.fasterxml.jackson.databind.exc.unrecognizedpropertyexception:  unrecognized field "employee" (class com.abc.employee), not marked ignorable (12 known properties: , "id", "name", ... [truncated]]) 

i not able understand why "employee" considered property. wrong in assuming class members considered properties?

the problem json object { } maps java class, , properties in json map java properties. first { } in json (which trying unmarshal employee), has property employee, employee class not have property for. that's why getting error. if try , unmarshal enclosed { }

{   "id": "c1654935-2602-4a0d-ad0f-ca1d514a8a5d",   "name": "smith" } 

it work employee has properties. if don't have control on json, can configure objectmapper unwrap root value

objectmapper mapper = new objectmapper(); mapper.configure(deserializationfeature.unwrap_root_value, true); 

but might have problem. unwrapping based on annotation on employee class, either @jsonrootname("employee") or @xmlrootelement(name = "employee"). latter though, need make sure have jaxb annotation support. that, need have jackson-module-jaxb-annotations, register module

mapper.registermodule(new jaxbannotationmodule()); 

this applies jaxb annotations you're using. without module, won't work.
