m and m/s unwanted in ele and speed

[kambei]

Following your example:

final GPX gpx = GPX.builder()
    .addTrack(track -> track
        .addSegment(segment -> segment
        .addPoint(p -> p.lat(48.20100).lon(16.31651).ele(283))
        .addPoint(p -> p.lat(48.20112).lon(16.31639).ele(278))
        .addPoint(p -> p.lat(48.20126).lon(16.31601).ele(274))))
    .build();

if I add ele and speed, instead of just the double value in the JSON also appears m and m/s and so the JSON is invalid:

Am I missing something?

I guess you tried to marshal the GPX object with a library like Jackson. I used classes to represent heights and speed (Length and Speed) and overrode the toString method. This methods append "m" and "m/s" to the value. To solve this problem you can implement your own serializers for this types. Baeldung describes it in this article: https://www.baeldung.com/jackson-custom-serialization

Thanks.
