⚠️ This library was integrated into the official Matomo Java Tracker library

A lightweight client library for JVM-based applications that helps you to track page views, events, visits using the Matomo Tracking API:

• Automatically performs bulk requests with a configurable delay (default: 1 second)
• Keeps queries until the request was transmitted successfully: If requests fail, the queries will not get lost.
• Supports nearly all tracking parameters
• The request API is designed with fluent builders and immutability.
• Performs asynchronous calls so that your application is not influenced by the Matomo endpoint speed
• Easy to use
• Well documented with Javadoc
• Ensures correct values are sent to Matomo Tracking API
• Includes debug logging
• Minimal dependencies (only SLF4J and JSR-305 annotations)
• Easy to integrate in frameworks, e.g. Spring: Just create the MatomoTracker Spring bean and use it in other beans

Include the dependency using Maven

<dependency>
  <groupId>org.drjekyll</groupId>
  <artifactId>matomo-tracker</artifactId>
  <version>1.2.0</version>
</dependency>

or Gradle with Groovy DSL:

implementation 'org.drjekyll:matomo-tracker:1.2.0'

or Gradle with Kotlin DSL:

implementation("org.drjekyll:matomo-tracker:1.2.0")

Run your build tool and add the tracker like in the following example:

TrackerConfiguration config = TrackerConfiguration.builder()
  .apiEndpoint(URI.create("https://your-domain.net/matomo/matomo.php"))
  .defaultSiteId(42) // if not explicitly specified by action
  .build();

// Prepare the tracker (stateless - can be used for multiple actions)
MatomoTracker tracker = new MatomoTracker(config);

// Track an action
CompletableFuture<Void> future = tracker.track(Action.builder()
  .name("User Profile / Upload Profile Picture")
  .url("https://your-domain.net/user/profile/picture")
  .visitorId(VisitorId.fromHash("[email protected]".hashCode()))
  // ...
.build());

// If you want to ensure the request has been handled:
if(future.isCompletedExceptionally()){
  // log, throw, ...
}

This example sends a request to a Matomo endpoint. Usually many more parameters should be set.

The Matomo Tracker currently supports the following builder methods:

• .apiEndpoint(...) An URI object that points to the Matomo Tracking API endpoint of your Matomo installation. Must be set.
• .defaultSiteId(...) If you provide a default site id, it will be taken if the action does not contain a site id.
• .defaultTokenAuth(...) If you provide a default token auth, it will be taken if the action does not contain a token auth.
• .delay(...) The duration on how long the tracker collects actions until they will be sent out as a bulk request. Default: 1 seconds
• .enabled(...) The tracker is enabled per default. You can disable it per configuration with this flag.
• .logFailedTracking(...) Will send errors to the log if the Matomo Tracking API responds with an errornous HTTP code
• .connectTimeout(...) allows you to change the default connection timeout of 10 seconds. 0 is interpreted as infinite, null uses the system default
• .socketTimeout(...) allows you to change the default socket timeout of 10 seconds. 0 is interpreted as infinite, null uses the system default
• .userAgent(...) used by the request made to the endpoint is MatomoJavaClient per default. You can change it by using this builder method.
• .proxyHost(...) The hostname or IP address of an optional HTTP proxy. proxyPort must be configured as well
• .proxyPort(...) The port of an HTTP proxy. proxyHost must be configured as well.
• .proxyUserName(...) If the HTTP proxy requires a user name for basic authentication, it can be configured with this method. Proxy host, port and password must also be set.
• .proxyPassword(...) The corresponding password for the basic auth proxy user. The proxy host, port and user name must be set as well.

To build and locally install the library and run the tests, just call

mvn install

Country.fromLanguageRanges now checks whether ranges are empty on extraction of country from language ranges.

Dependency updates

Requests will be sent as bulk requests now. The tracker waits a configurable duration (default: 1 second) until it sends out the collected requests.
