51Degrees Geo-Location Java  4.1Newer Version 4.2

Geo-location services for 51Degrees Pipeline

CombiningServices.java

Getting started example of using 51Degrees geo-location alongside 51Degrees device detection.This example is available in full on GitHub.

Required Maven Dependencies:

  • com.51degrees.geo-location
  • com.51degrees.device-detection
  1. Build new cloud-based geo-location, and device detection engines, along with the cloud request engine on which they rely.
    CloudRequestEngine cloudRequestEngine =
    new CloudRequestEngineBuilder(loggerFactory, httpClient)
    .setResourceKey(resourceKey)
    .build();
    AspectEngine deviceDetectionEngine =
    new DeviceDetectionCloudEngineBuilder(loggerFactory, httpClient, cloudRequestEngine)
    .build();
    AspectEngine locationEngine =
    new GeoLocationCloudEngineBuilder(loggerFactory, cloudRequestEngine)
    .build(Enums.GeoLocationProvider.FiftyOneDegrees);
  2. Build a new Pipeline containing the engines which were just created.
    Pipeline pipeline = new PipelineBuilder(loggerFactory)
    .addFlowElement(cloudRequestEngine)
    .addFlowElement(deviceDetectionEngine)
    .addFlowElement(locationEngine)
    .build();

Note that while the cloud request engine must be run before the others, the device detection and geo-location engines can be run in parallel.

Pipeline pipeline = new PipelineBuilder(loggerFactory)
.addFlowElement(cloudRequestEngine)
.addFlowElementsParallel(new FlowElement[]{deviceDetectionEngine, locationEngine})
.build();
  1. Create a new FlowData instance ready to be populated with evidence for the Pipeline.
    FlowData data = pipeline.createFlowData();
  2. Process a longitude, latitude and User-Agent to retrieve the values associated with with the location and device for the selected properties.
    data
    .addEvidence(EVIDENCE_HEADER_USERAGENT_KEY, userAgent)
    .addEvidence(EVIDENCE_GEO_LAT_PARAM_KEY, "51.458048")
    .addEvidence(EVIDENCE_GEO_LON_PARAM_KEY, "-0.9822207999999999")
    .process();
  3. Extract the value of a property as a string from the results.
    AspectPropertyValue<Boolean> isMobile = data.get(Device.class).getIsMobile();
    AspectPropertyValue<String> country = data.get(GeoData.class).getCountry();
