POJAXB - Set an XmlAdapter only for an specific sub type of an element?
text
Body
copied!<p>I have to generate a xml element that can have as value any "primitive type" (xsd:string, xsd:boolean, etc). Examples:</p> <pre><code><field xsi:type="xsd:string" name="aString">String Value</field> <field xsi:type="xsd:dateTime" name="aDate">2011-10-21</field> <field xsi:type="xsd:dateTime" name="aDateTime">2011-10-21T12:00:00</field> ... </code></pre> <p>So, I use this implementation that makes JAXB decide the <code>xsi:type</code> of the primitive type:</p> <pre><code>public class Field { @XmlAttribute private String name; @XmlElement Object value; } </code></pre> <p>and it is working as expected but all the java.util.Date gets the type <code>xs:dateTime</code> ... </p> <p>Now I want to change the behavior of the marshaller ONLY when the 'value' object is an instance of java.util.Date to obtains fields like this:</p> <pre><code><field xsi:type="xsd:date" name="aDate">2011-10-21</field> <field xsi:type="xsd:dateTime" name="aDateTime">2011-10-21T12:00:00</field> </code></pre> <p>So I create an adapter, but if I try this:</p> <pre><code>@XmlElement @XmlJavaTypeAdapter(DateAdapter.class) Object value; </code></pre> <p>The adapter must handles a java.lang.Object type</p> <pre><code>public class DateAdapter extends XmlAdapter<String, Object> {...} </code></pre> <p>But I do not want to loose the JAXB marshallers for all the others objects (Integer, Double, etc) ... </p> <p>there is a way to set an adapter for a specific subtype of an element?</p>
