Given the following class:
@XmlRootElement(name = "Person")
@AutoValue
@CopyAnnotations
public abstract class Person {
@XmlElement
abstract String name();
public static Builder builder() {
return new AutoValue_Person.Builder();
}
@AutoValue.Builder
public abstract static class Builder {
public abstract Builder name(String name);
public abstract Person build();
}
}
When I run:
Person person = Person.builder().name("Test").build();
StringWriter stringWriter = new StringWriter();
JAXB.marshal(person, stringWriter);
String xmlContent = stringWriter.toString();
System.out.println(xmlContent);
I always get:
com.example.commands.AutoValue_Person does not have a no-arg default constructor.
this problem is related to the following location:
at com.example.commands.AutoValue_Person
JAXB annotation is placed on a method that is not a JAXB property
this problem is related to the following location:
at @javax.xml.bind.annotation.XmlElement(name=##default, namespace=##default, type=class javax.xml.bind.annotation.XmlElement$DEFAULT, required=false, defaultValue=�, nillable=false)
at com.example.commands.AutoValue_Person
I would like to make it work without the need of creating an adapter as suggested in http://blog.bdoughan.com/2010/12/jaxb-and-immutable-objects.html . I have too many data objects and I don't want to duplicate each one of them. Curious enough, there seems to be tons of utilisations for AutoValue with JAXB in GitHub without the use of adapters: https://github.com/search?q=XmlRootElement+autovalue&type=Code
I actually realized the problem after studying your github link, specifically this one: https://github.com/google/nomulus/blob/8f2a8835d7f09ad28806b2345de8d42ebe781fe6/core/src/main/java/google/registry/model/contact/ContactInfoData.java
Notice the naming structure used in the sample AutoValue Java class, it still uses the getVal
and setVal
Here is a simple example based on my code that now works:
import com.google.auto.value.AutoValue;
import javax.xml.bind.annotation.XmlAttribute;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
import javax.xml.bind.annotation.XmlType;
@XmlRootElement(name = "Customer")
@XmlType(propOrder = {"name", "age", "id"})
@AutoValue.CopyAnnotations
@AutoValue
public abstract class Customer {
public static Builder builder() {
return new AutoValue_Customer.Builder();
}
@XmlElement(name = "name")
abstract String getName();
@XmlElement(name = "age")
abstract int getAge();
@XmlAttribute(name = "id")
abstract int getId();
@AutoValue.Builder
public abstract static class Builder {
public abstract Builder setName(String name);
public abstract Builder setAge(int age);
public abstract Builder setId(int id);
public abstract Customer build();
}
}
Notice I use setName(String name)
in the builder but String getName()
in the class itself. Try to refactor your code to those conventions.
