While playing with SerializableProvider in RestEASY beta 3 I got errors due
to a MediaType being changed to
"application/x-java-serialized-object;charset=UTF-8" by a global servlet
Spring filter. Charset is useless but I think the @Provider should use
MediaType.isCompatible instead of String equels.
Here is the modification I made :
@Provider
@Produces(SerializableProvider.MIMETYPE)
@Consumes(SerializableProvider.MIMETYPE)
public class SerializableProvider implements
MessageBodyReader<Serializable>, MessageBodyWriter<Serializable> {
/** Marshaller for Java serialized objects */
public final static String MIMETYPE =
"application/x-java-serialized-object";
/** Corresponding MediaType */
public final static MediaType MEDIATYPE = new MediaType("application",
"x-java-serialized-object");
@Override
public boolean isWriteable(Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType) {
return Serializable.class.isAssignableFrom(type) &&
MEDIATYPE.isCompatible(mediaType);
}
@Override
public long getSize(Serializable t, Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType) {
return -1;
}
@Override
public void writeTo(Serializable t, Class<?> type, Type genericType,
Annotation[] annotations, MediaType mediaType,
MultivaluedMap<String, Object> httpHeaders, OutputStream
entityStream) throws IOException,
WebApplicationException {
BufferedOutputStream bos = new BufferedOutputStream(entityStream);
ObjectOutputStream oos = new ObjectOutputStream(bos);
oos.writeObject(t);
oos.close();
}
@Override
public boolean isReadable(Class<?> type, Type genericType, Annotation[]
annotations, MediaType mediaType) {
return Serializable.class.isAssignableFrom(type)
&& MEDIATYPE.isCompatible(mediaType);
}
@Override
public Serializable readFrom(Class<Serializable> type, Type
genericType, Annotation[] annotations,
MediaType mediaType, MultivaluedMap<String, String>
httpHeaders, InputStream entityStream)
throws IOException, WebApplicationException {
BufferedInputStream bis = new BufferedInputStream(entityStream);
ObjectInputStream ois = new ObjectInputStream(bis);
try {
return Serializable.class.cast(ois.readObject());
} catch (ClassNotFoundException e) {
throw new WebApplicationException(e);
}
}
}
