Hello,
My program successfully reads features from a shapefile. At some point, long
after the shapefile was read, I get the following message in my console:
org.geotools.data.shapefile.ShapefileFeatureReader finalize
WARNING: There is code leaving shapefile readers unclosed, this might result in
file system locks not being cleared.
I tried closing the ShapefileFeatureReader instance manually but there is no
“close” method available. Calling “dispose” does not help. Looking at the
GeoTools code[1] (line 298), a “close” method is defined but code outside the
package cannot call it.
This is how I read shapefiles:
public static SimpleFeatureCollection fromShapefile(String pathname) throws
Exception {
File file = new File(pathname);
Map<String, Serializable> connectionParameters = new HashMap<>();
connectionParameters.put("url", file.toURI().toURL());
DataStore dataStore =
DataStoreFinder.getDataStore(connectionParameters);
String[] featureTypes = dataStore.getTypeNames();
if (featureTypes.length != 1) {
throw new Exception();
}
SimpleFeatureSource featureSource =
dataStore.getFeatureSource(featureTypes[0]);
SimpleFeatureCollection features = featureSource.getFeatures();
dataStore.dispose();
return features;
}
Is this the correct way to do it?
My console gets spammed by the warning message and makes it difficult to read
the console output my program generates. Is there anything I can do to disable
warning messages by GeoTools?
