Hello there,
I have an application based on camel-quarkus that (1) split xml
payloads using StAX and JAXB, (2) use Dozer to map each record to
domain objects annotated with protostream and (3) put each domain
object into an Infinispan remote cache.
JAXB classes are generated through xjc from a schema delivered by a
central Institution.
So far so good; everything works fine in non-native mode.
Problems come out when I try to run the native executable.
I get the following Exception during the mapping process and in
particular mapping a java.util.Date field.
For the record Protostream supports just Date and Instant for time fields.
Dest field type: java.util.Date:
com.github.dozermapper.core.converters.ConversionException:
java.lang.NoSuchMethodException: java.util.Date.<init>(long)

Hereafter an excerpt of the route managing the application logic; I've
used object names of the common Microsoft examples available in
Internet (Books/Book xsd and xml)
@ApplicationScoped
public class FileLoadRouter extends RouteBuilder {
@ConfigProperty(name = "code-with-quarkus.inputFolder")
String inputFolder;
@Override
public void configure() throws Exception {
DataFormat jaxb = new
JaxbDataFormat(JAXBContext.newInstance(ObjectFactory.class));
from(String.format("file:%s?noop=true&moveFailed=${file:name}.error&include=.*.xml",
inputFolder))
.streamCaching()
.log("Starting file process ${file:onlyname} " + "${file:size}")
.split().tokenizeXML("book", "*").streaming()
.unmarshal(jaxb)
.to("dozer:bookMapping?mappingFile=bookMapping.xml&targetModel=org.acme.dto.Book")
.bean(infinispanService, "load")
.choice()
.when(header(Exchange.SPLIT_COMPLETE))
.log("File ${file:onlyname} completed")
.endChoice();
}
}
Here the mapping file (bookMapping.xml):
<?xml version="1.0" encoding="UTF-8"?>
<mappings xmlns="http://dozermapper.github.io/schema/bean-mapping";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://dozermapper.github.io/schema/bean-mapping
https://dozermapper.github.io/schema/bean-mapping.xsd";>
<mapping type="one-way" wildcard="false">
<class-a>org.acme.jaxb.BooksForm</class-a>
<class-b>org.acme.dto.Book</class-b>
<field>
<a>book[0].id</a>
<b>key</b>
</field>
<field>
<a>book[0].author</a>
<b>author</b>
</field>
<field>
<a>book[0].pubDate</a>
<b>publicationDate</b>
</field>
<field>
<a>book[0].price</a>
<b>price</b>
</field>
</mapping>
</mappings>
I've tried to hard-code the mapping in a small part of the application
and everything works fine even running the native executable. The same
if I use Instant instead of Date. Unfortunately it's a complex
microservice and I don't want to change the definition, said that
Instant should be definitely meaningless for dates without seconds
Am I missing something in Dozer (or Quarkus) configuration for
java.util.Date fields? Or is it a bug related to native compilation
for camel-quarkus-dozer?
Many thanks
