java - How to use @XmlJavaTypeAdapter in @RestController parameters? -

i have following restcontroller, , get-query controller thedate=2016-08-08 format.

it should automatically converted java.time.localdate. xmladapter not working. why?

import java.time.localdate; import java.time.format.datetimeformatter; import javax.xml.bind.annotation.adapters.xmladapter;  public class localdateadapter extends xmladapter<string, localdate> {      @override     public localdate unmarshal(string v) throws exception {         return localdate.parse(v, datetimeformatter.iso_local_date);     }      @override     public string marshal(localdate v) throws exception {         return datetimeformatter.iso_local_date.format(date);     } }  @restcontroller public class myservlet {    @requestmapping(value = "/", method = requestmethod.get)    private string test(restparams p) {     } }  @xmlrootelement @xmlaccessortype(xmlaccesstype.field) public class restparams {         @valid         @notnull         @xmlelement(required = true, nillable = false)         @xmljavatypeadapter(value = localdateadapter.class)         private localdate thedate; } 

result:

'thedate': failed convert property value of type [java.lang.string] required type [java.time.localdate] property 'thedate'; nested exception org.springframework.core.convert.conversionfailedexception: failed convert type [java.lang.string] type [@javax.validation.valid @javax.validation.constraints.notnull @javax.xml.bind.annotation.xmlelement @javax.xml.bind.annotation.adapters.xmljavatypeadapter java.time.localdate] value '2016-08-08'; nested exception java.time.format.datetimeparseexception: text '2016-08-08' not parsed @ index 2

i don't know why it's not working, solved using spring annotation:

   @org.springframework.format.annotation.datetimeformat.datetimeformat(iso = iso.date)    private java.time.localdate thedate;
