Datahotel client
Getting started
Include dependency in your pom.xml:
<dependency>
<groupId>no.difi.commons</groupId>
<artifactId>commons-datahotel</artifactId>
<version>0.9.0</version>
</dependency>
Start fetching data:
// Build client for municipalities
Datahotel<DifiGeoKommune> datahotel = DatahotelBuilder.create(DifiGeoKommune.class).build();
// Find all minicipalities starting with "Os" in name
for (DifiGeoKommune municipality : datahotel.search("Os*")) {
System.out.println(municipality.getNavn());
}
// Loop all municipalities in data set
for (DifiGeoKommune municipality : datahotel.all()) {
System.out.println(municipality.getNavn());
}
Query datahotel using your own classes
This example shows how to extend functionality of the library.
// Create class
// Please note setters are needed when using looping whole data set.
@Dataset("difi/geo/fylke")
public class DifiGeoFylke {
private String nummer, navn;
public String getNummer() {
return nummer;
}
public String getNavn() {
return navn;
}
}
// Build client for counties (using annotation)
Datahotel<DifiGeoFylke> datahotel = DatahotelBuilder.create(DifiGeoFylke.class).build();
// Build client for counties (not using annotation)
Datahotel<DifiGeoFylke> datahotel = DatahotelBuilder.create(DifiGeoFylke.class, "difi/geo/fylke").build();
// List all counties:
for (DifiGeoFylke county : datahotel.page(1)) {
System.out.println(String.format("%s: %s", county.getNummer(), county.getNavn()));
}
// Print name of county number 14
System.out.println(datahotel.field("nummer", 14).single().getNavn());
