java - @JsonFormat for date parsing in JAX-RS service is ignored -

i'm trying pass date jax-rs service. checking other questions like: date format mapping json jackson

the answers , documentation show there jackson annotation should allow date formatting.

public class solutionfilter {     @matrixparam("todate")     @jsonformat(shape=jsonformat.shape.string, pattern="yyyy-mm-dd", timezone="cet")     private date todate;      public void settodate(date todate) {         this.todate = todate;     } } 

upon calling rest-service i'm getting parseexception:

caused by: java.text.parseexception: unparseable date: "2016-01-01"   @ java.text.dateformat.parse(dateformat.java:366)   @ org.glassfish.jersey.message.internal.httpdateformat.readdate(httpdateformat.java:137)   @ org.glassfish.jersey.server.internal.inject.paramconverters$dateprovider$1.fromstring(paramconverters.java:259) 

it seems annotation ignored. debugging parse method pattern set eee, dd mmm yyyy hh:mm:ss zzz , eee mmm d hh:mm:ss yyyy.

i'm using spring 4.2.1, jersey 2.22 binds jackson 2.5.4.

how can dates parsed correct pattern?

update: thinking further json used output parsing. jax-rs parameter parsing.

param conversion done paramconverters. if follow stacktrace, see paramconverters$dateprovider. next call httpdateformat class parsing.

if @ top of class, see date formats supported. these standard http data formats

/**  * date format pattern rfc 1123.  */ private static final string rfc1123_date_format_pattern = "eee, dd mmm yyyy hh:mm:ss zzz"; /**  * date format pattern rfc 1036.  */ private static final string rfc1036_date_format_pattern = "eeee, dd-mmm-yy hh:mm:ss zzz"; /**  * date format pattern ansi c asctime().  */ private static final string ansi_c_asctime_date_format_pattern = "eee mmm d hh:mm:ss yyyy"; 

as far know or can tell, there no configuration available can add list. other option write own converter. example

@provider public class dateparamconverterprovider implements paramconverterprovider {      private final string format;      public dateparamconverterprovider(string dateformat) {         this.format = dateformat;     }      @override     public <t> paramconverter<t> getconverter(class<t> rawtype,                                                type generictype,                                                annotation[] annotations) {          if (rawtype != date.class) { return null; }          return (paramconverter<t>) new paramconverter<date>() {              @override             public date fromstring(string value) {                 simpledateformat formatter = new simpledateformat(format);                 try {                     return formatter.parse(value);                 } catch (exception ex) {                     throw new webapplicationexception("bad formatted date", 400);                 }             }              @override             public string tostring(date date) {                  return new simpledateformat(format).format(date);              }         };     } } 

here complete test case using jersey test framework

public class dateparamtest extends jerseytest {      private static final string format = "mm-dd-yyyy";      @path("date")     public static class dateresource {         @get         public string get(@matrixparam("since") date date) {             return new simpledateformat(format).format(date);         }     }      @override     public resourceconfig configure() {         return new resourceconfig(dateresource.class)                 .register(new dateparamconverterprovider(format));     }      @test     public void should_return_same_date_and_format() {         final string date = "09-30-2015";         response response = target("date").matrixparam("since", date)                 .request().get();         assertequals(200, response.getstatus());         string returndate = response.readentity(string.class);         assertequals(date, returndate);         system.out.println(returndate);     } }
