Hi,
You can mount with a coding strategy in Application.init, something like
.. (I do it for attachment)
mount(new MyMixedParamUrlCodingStrategy("/images",
Page.class, new String[] { "id", "move" }) {
@Override
public IRequestTarget decode(RequestParameters
requestParameters) {
try {
ValueMap params =
decodeParameters(requestParameters.getPath().substring(getMountPath().length()),
requestParameters.getParameters());
String id = params.getString("id");
String move = params.getString("move");
if (StringUtils.isNotBlank(id)) {
...
return new ResourceStreamRequestTarget(...);
}
return new
WebErrorCodeResponseTarget(HttpServletResponse.SC_NOT_FOUND);
nice to know how to return errors :)
//return super.decode(requestParameters);
} catch (RuntimeException exc) {
throw exc;
} catch (Exception exc) {
throw new RuntimeException("wrap: " +
exc.getMessage(), exc);
}
}
});
Thanks, I managed to do something like this:
getSharedResources().add( "snapshot", new CameraSnapshotResource() );
mount( new SharedResourceRequestTargetUrlCodingStrategy( "/snapshot", new
ResourceReference( "snapshot" ).getSharedResourceKey() ) );
public class CameraSnapshotResource extends DynamicWebResource {
@SpringBean
private CameraSnapshotService cameraSnapshotService;
public CameraSnapshotResource() {
InjectorHolder.getInjector().inject( this );
}
@Override
protected ResourceState getResourceState() {
ValueMap parameters = getParameters();
Long id = parameters.getLong( "id" );
final CameraSnapshot snapshot = cameraSnapshotService.findById(
id );
return new ResourceState() {
@Override
public String getContentType() {
return "image/jpeg";
}
@Override
public byte[] getData() {
try {
return snapshot.getData().getBytes( 1,
snapshot.getSize() );
} catch ( SQLException e ) {
throw new RuntimeException( "unable to fetch
image data", e );
}
}
};
}
}
Now I have a problem:
http://host/wicketapp/snapshot?id=1 works
http://host/wicketapp/snapshot/id/1 does not (although when debugging I
see parameters get decoded).
