I think this is because of jaxb than cxf .You need to develop your own xjc plugin to do it.
https://jaxb.java.net/nonav/2.0.2/docs/developPlugins.html
Also google about developing and plugging your own xjc
Creating a plugin was the right way to go.Resusing the code in this forum
public class PrivateMemberPlugin
extends Plugin
{
@Override
public String getOptionName()
{
return "Xpm";
}
@Override
public String getUsage()
{
return " -Xpm : Change members visibility to private";
}
@Override
public boolean run(Outline model, Options opt, ErrorHandler errorHandler)
throws SAXException
{
for (ClassOutline co : model.getClasses())
{
JDefinedClass jdc = co.implClass;
// avoid concurrent modification by copying the fields in a new list
List<JFieldVar> fields = new ArrayList<JFieldVar>(jdc.fields().values());
for (JFieldVar field : fields)
{
// never do something with serialVersionUID if it exists.
if (!field.name().equalsIgnoreCase("serialVersionuid"))
{
// only try to change members that are not private
if (field.mods().getValue() != JMod.PRIVATE)
{
// since there is no way to change the visibilty, remove the field an recreate it
jdc.removeField(field);
jdc.field(JMod.PRIVATE, field.type(), field.name());
}
}
}
}
return true;
}
}
