Orika convert String to Date when map data from HashMap to bean - orika

Question

I use orika 1.5.2 . when map data from HashMap to bean with convert String to java.util.Date, I get the Exception:
java.lang.ClassCastException: java.lang.String cannot be cast to java.util.Date
DateToStringConverter also not take effect. But the exception not come out when I map data from Bean A to Bean B.
How can I convert String to Date when I map data from a Map to bean?
code:
public class UserA {
private Date birthday;
public Date getBirthday() {
return birthday;
}
public void setBirthday(Date birthday) {
this.birthday = birthday;
}
#Override
public String toString() {
return "UserA [birthday=" + birthday + "]";
}
}
public static void main(String[] args){
HashMap map = new HashMap();
map.put("birthday", "2014-04-28");
UserA ua = new UserA();
MapperFactory mapF = new DefaultMapperFactory.Builder().mapNulls(false).build();
mapF.getConverterFactory().registerConverter(new DateToStringConverter("yyyy-MM-dd"));
mapF.getMapperFacade().map(map, ua);
}
exception:
Exception

U need Object to Date converter, not DateToStringConverter
user:
#Data
public class UserA {
private Date birthday;
}
add Converter
public class ObjectToDateConverter extends CustomConverter<Object, Date> {
#Override
public Date convert(Object source, Type<? extends Date> destinationType, MappingContext context) {
if (source instanceof String) {
try {
return new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault()).parse((String) source);
} catch (ParseException e) {
return null;
}
}
return null;
}
}
test:
#Test
public void testMap(){
HashMap map = new HashMap();
map.put("birthday", "2018-10-14");
UserA ua = new UserA();
MapperFactory mapF = new DefaultMapperFactory.Builder().mapNulls(false).build();
mapF.getConverterFactory().registerConverter(new ObjectToDateConverter());
mapF.getMapperFacade().map(map, ua);
}
