I have a date/time value, openDtGmt, is part of an xml input from a legacy system that cannot be changed.
An example of the date/time: 2019 3 4 14 44 20 -5
I am using Jackson to map the xml into an object.
I created a custom Deserialize class to map this string into a ZonedDateTime object.
When running the unit test I get the error:

com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot
construct instance of
com.fedex.ground.tms.javaserver.dock.closetrailer.model.StandardLoadComposite
(although at least one Creator exists): no String-argument
constructor/factory method to deserialize from String value ('2019 3 4
14 44 20 -5')

This date is in a class TrailerLoad which is part of StandardLoadComposite which is part of the parent class CloseTrailerXml
This is the classes:

class CloseTrailerXml 
@JacksonXmlElementWrapper(localName = "trailer_standard_loads", useWrapping = true)
List<StandardLoadComposite> trailer_standard_loads;

...other classes


@JsonIgnoreProperties(ignoreUnknown=true)
public class StandardLoadComposite 

 public StandardLoadComposite()

 @JsonUnwrapped
 private TrailerLoad trailerload;

...other classes


@JsonRootName("trailer_standard_loads")
@JsonIgnoreProperties(ignoreUnknown=true)
public class TrailerLoad 

 private Integer trailerLoadSeq;
 @JsonProperty("open_dt_gmt") //this is the datetime deserialized
 private ZonedDateTime openDtGmt;
...other member variables

Now the Deserializer:

public class ZonedDateTimeDeserializer extends JsonDeserializer<ZonedDateTime> {

 protected final Log log = LogFactory.getLog(TMSTransactionBean.class.getName());

 @Override
 public ZonedDateTime deserialize(JsonParser p, DeserializationContext ctx)
 throws IOException 
 String dateTimeString = p.getText();

 try 
 ..string manipulation...
 dateTimeFromString = ZonedDateTime.parse(formattedDateTimeString);
 return dateTimeFromString;
 catch (DateTimeParseException e) 
 log.error("Error deserializing the date from scanner xml message: " + e.getMessage());
 return null;
 
 

This is the call to map the xml to the object:

 //creating a module
SimpleModule module = new SimpleModule();
 module.addDeserializer(ZonedDateTime.class, new ZonedDateTimeDeserializer());

XmlMapper xmlMapper = new XmlMapper();
xmlMapper.registerModule(new JavaTimeModule());
xmlMapper.configure(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS, false);
xmlMapper.registerModule(module);

xmlMapper.setSerializationInclusion(Include.NON_NULL);

CloseTrailerXml closeTrailerXml = xmlMapper.readValue(message, CloseTrailerXml.class);

I just want to deserialize one field in the TrailerLoad class. The error is that the StandardLoadComposite class does not have a constructor for the date string. The date is actually in the TrailerLoad class that is in the StandardLoadComposite.
I don't understand how to create the constructor for date field that is a string in the xml to the ZonedDateTime in the TrailerLoad class.
