JAXB binding for xs:integer to Java Integer instead of BigInteger

Question

The following discussions should be avoided. What this question is NOT:

• using xs:int instead of xs:integer.
• using primitive int instead of Integer.
• why do you need this.
• what are you gonna do if etc.

QUESTION:

I would like an example of a jaxb binding declaration to override the default mapping of xs:integer to Java BigInteger, so that xjc would produce Java Integer instead.

e.g.

<xs:attribute name="id" type="xs:integer"/>

should produce

@XmlAttribute(name = "id")
Integer id;

and not

@XmlAttribute(name = "id")
BigInteger id;

Answer 1

You could add the following to your bindings file:

<globalBindings>
    <javaType xmlType="xs:integer" name="java.lang.Integer"/> 
</globalBindings>

This will produce, for example:

@XmlAttribute(name = "id")
@XmlJavaTypeAdapter(Adapter1 .class)
protected Integer id;

public int getId() {
    if (id == null) {
        return new Adapter1().unmarshal("0");
    } else {
        return id;
    }
}

public void setId(Integer value) {
    this.id = value;
}
