Geocoder Component

Available as of Camel 2.12

The geocoder: component is used for looking up geocodes (latitude and longitude) for a given address, or reverse lookup. The component uses the Java API for Google Geocoder library.

Maven users will need to add the following dependency to their pom.xml for this component:

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-geocoder</artifactId>
    <version>x.x.x</version>
    <!-- use the same version as your Camel core version -->
</dependency>

URI format

geocoder:address:name[?options]
geocoder:latlng:latitude,longitude[?options]

Options

You can append query options to the URI in the following format, ?option=value&option=value&...

 

Proxy

The following proxy options can also be set on the GeoCoderEndpoint

 

Exchange data format

Camel will deliver the body as a com.google.code.geocoder.model.GeocodeResponse type.
And if the address is "current" then the response is a String type with a JSON representation of the current location.

If the option headersOnly is set to true then the message body is left as-is, and only headers will be added to the Exchange.

Message Headers

Notice not all headers may be provided depending on available data and mode in use (address vs latlng).

Samples

In the example below we get the latitude and longitude for Paris, France

  from("direct:start")
    .to("geocoder:address:Paris, France")

If you provide a header with the CamelGeoCoderAddress then that overrides the endpoint configuration, so to get the location of Copenhagen, Denmark we can send a message with a headers as shown:

template.sendBodyAndHeader("direct:start", "Hello", GeoCoderConstants.ADDRESS, "Copenhagen, Denmark");

To get the address for a latitude and longitude we can do:

  from("direct:start")
    .to("geocoder:latlng:40.714224,-73.961452")
    .log("Location ${header.CamelGeocoderAddress} is at lat/lng: ${header.CamelGeocoderLatlng} and in country ${header.CamelGeoCoderCountryShort}")

Which will log

Location 285 Bedford Avenue, Brooklyn, NY 11211, USA is at lat/lng: 40.71412890,-73.96140740 and in country US

To get the current location you can use "current" as the address as shown:

  from("direct:start")
    .to("geocoder:address:current")
