51Degrees Device Detection Java  4.1

Device detection services for 51Degrees Pipeline

mvc/configuration/ExampleMvcConfig.java

Spring MVC device detection exampleThis example shows how to:

  1. Set up configuration options to add elements to the 51Degrees Pipeline.
    1 <PipelineOptions>
    2  <Elements>
    3  <Element>
    4  <BuildParameters>
    5  <EndPoint>https://cloud.51degrees.com/api/v4</EndPoint>
    6  <!-- Obtain a resource key for free at
    7  https://configure.51degrees.com
    8  Make sure to include the 'BrowserName','BrowserVendor',
    9  'BrowserVersion','HardwareName','HardwareVendor',
    10  'PlatformName','PlatformVendor','PlatformVersion'
    11  properties as they are used by this example. -->
    12  <ResourceKey>!!YOUR_RESOURCE_KEY!!</ResourceKey>
    13  </BuildParameters>
    14  <BuilderName>CloudRequestEngine</BuilderName>
    15  </Element>
    16  <Element>
    17  <BuilderName>DeviceDetectionCloudEngine</BuilderName>
    18  </Element>
    19  </Elements>
    20 </PipelineOptions>

Alternatively, to use the on-premise API with automatic updates enabled, replace the cloud element in the config with the new configuration.

1 <PipelineOptions>
2  <Elements>
3  <Element>
4  <BuildParameters>
5  <AutoUpdate>true</AutoUpdate>
6  <DataFileSystemWatcher>false</DataFileSystemWatcher>
7  <CreateTempDataCopy>true</CreateTempDataCopy>
8  <!-- Obtain your own license key and enterprise data file
9  from https://51degrees.com. -->
10  <DataUpdateLicenseKey>[[Your License Key]]</DataUpdateLicenseKey>
11  <DataFile>D:\[[Path to data file]]\51Degrees-EnterpriseV4.1.hash</DataFile>
12  <PerformanceProfile>LowMemory</PerformanceProfile>
13  </BuildParameters>
14  <BuilderName>DeviceDetectionHashEngineBuilder</BuilderName>
15  </Element>
16  </Elements>
17 </PipelineOptions>
  1. Set up MVC, enable configuration, and add the Pipeline component.
    @EnableWebMvc
    @Configuration
    @ComponentScan({"fiftyone.pipeline.web.examples.mvc.controller","fiftyone.pipeline.web.mvc"})
    public class ExampleMvcConfig extends WebMvcConfigurerAdapter {
    ...
  2. Configure the interceptor.
    public class ExampleMvcConfig extends WebMvcConfigurerAdapter {
    ...
    @Bean
    public FiftyOneInterceptorConfig fiftyOneInterceptorConfig() {
    final FiftyOneInterceptorConfigDefault bean = new FiftyOneInterceptorConfigDefault();
    bean.setDataFilePath(servletContext.getRealPath("/WEB-INF/51Degrees-Cloud.xml"));
    bean.setClientsidePropertiesEnabled(true);
    return bean;
    }
    ...
  3. Enable client-side code to improve detection accuracy on devices like iPhones.
    public class ExampleMvcConfig extends WebMvcConfigurerAdapter {
    ...
    @Override
    public void addViewControllers(final ViewControllerRegistry registry) {
    enableClientsideProperties(registry);
    }
    ...
  4. Add the interceptor.
    public class ExampleMvcConfig extends WebMvcConfigurerAdapter {
    ...
    @Autowired
    FiftyOneInterceptor fiftyOneInterceptor;
    @Override
    public void addInterceptors(final InterceptorRegistry registry) {
    registry.addInterceptor(fiftyOneInterceptor);
    }
    ...
  5. Inject the FlowDataProvider into a controller.
    @Controller
    @RequestMapping("/")
    public class ExampleController {
    private FlowDataProvider flowDataProvider;
    @Autowired
    public ExampleController(FlowDataProvider flowDataProvider) {
    this.flowDataProvider = flowDataProvider;
    }
    ...
  6. Use the results contained in the flow data to display something on a page view.
    @Controller
    @RequestMapping("/")
    public class ExampleController {
    ...
    @RequestMapping(method = RequestMethod.GET)
    public String get(ModelMap model, HttpServletRequest request) {
    FlowData data = flowDataProvider.getFlowData(request);
    DeviceData device = data.get(DeviceData.class);
    model.addAttribute("browser", device.getBrowserVendor() + " " + device.getBrowserName() + " " + device.getBrowserVersion());
    model.addAttribute("device", device.getHardwareVendor() + " " + device.getHardwareName());
    model.addAttribute("os", device.getPlatformVendor() + " " + device.getPlatformName() + " " + device.getPlatformVersion());
    return "example";
    }
    ...

    Controller
