the class EditorResources method getTile.

@GET
@javax.ws.rs.Path("/tiles/{z}/{x}/{y}.mvt")

        }
    } catch (Exception ex) {
        logger.error("Tile error", ex);

Example 2 with PostgresQuery

use of com.baremaps.tile.postgres.PostgresQuery in project baremaps by baremaps.

the class View method call.

@Override
public Integer call() throws Exception {
    ObjectMapper objectMapper = defaultObjectMapper();
    BlobStore blobStore = options.blobStore();
    TileJSON tileJSON = objectMapper.readValue(blobStore.get(this.tileset).getInputStream(), TileJSON.class);
    CaffeineSpec caffeineSpec = CaffeineSpec.parse(cache);
    DataSource datasource = PostgresUtils.datasource(database);
    List<PostgresQuery> queries = asPostgresQuery(tileJSON);
    TileStore tileStore = new PostgresTileStore(datasource, queries);
    TileStore tileCache = new TileCache(tileStore, caffeineSpec);
    // Configure the application
    ResourceConfig application = new ResourceConfig().register(CorsFilter.class).register(ViewerResources.class).register(contextResolverFor(objectMapper)).register(new AbstractBinder() {

        @Override
        protected void configure() {
            bind(tileset).to(URI.class).named("tileset");
            bind(style).to(URI.class).named("style");
            bind(blobStore).to(BlobStore.class);
            bind(tileCache).to(TileStore.class);
        }

    logger.info("Listening on {}", serverContext.listenAddress());
    serverContext.awaitShutdown();
    return 0;
}

Example 3 with PostgresQuery

use of com.baremaps.tile.postgres.PostgresQuery in project baremaps by baremaps.

the class TilesetsResource method loadTileStore.

private TileStore loadTileStore(UUID tilesetId) {
    TileJSON tileset = jdbi.withHandle(handle -> handle.createQuery("select tileset from tilesets where id = :id").bind("id", tilesetId).mapTo(TILESET).one());
    List<PostgresQuery> queries = tileset.getVectorLayers().stream().flatMap(layer -> layer.getQueries().stream().map(query -> new PostgresQuery(layer.getId(), query.getMinzoom(), query.getMaxzoom(), query.getSql()))).collect(Collectors.toList());
    return new PostgresTileStore(dataSource, queries);
