Collection of independent libraries on top of Spring Boot to provide a faster setup of jvm microservices.

"I never did anything by accident, nor did any of my inventions come by accident; they came by work." - Thomas Edison


Build codecov Known Vulnerabilities Maven Central license

Have a look at the release notes for details about updates and changes.


This project contains a number of independent libraries on top of Spring Boot to provide a faster setup of jvm microservices. The libraries are used in different projects at OTTO. It's purpose is to provide a common implementation for cross-cutting requirements like:

  • Health checks that are used to tell the load balancer or mesos platform whether or not a service is healthy.
  • A status page/document that is used to give information about the current state of the service. Status information also include details about sub-components, background jobs like imports, and so on.
  • A simple job handling library that is used to run asynchronous background jobs, which for example can be used to run data imports from other systems.
  • An optional MongoDB-based implementation of a JobRepository
  • Support for MongoDB-based repositories in case you do not like Spring Data
  • Support for feature toggles based on Togglz

... plus all the features of Spring Boot.


Semantic Versioning v2.0.0 is used to specify the version numbers.

This project maintains its roadmap with issues and milestones.

2.7.x: Edison Microservices for Spring Boot 2.7.x - Compatible with Java 11 and greater

Migration from Edison 1.x to Edison 2

Edison 2 has several breaking changes that will make a refactoring of your current application necessary. For a list of the actual changes, please take a look at the Changelog.

When migrating, take care of the following adjustments:

  • Follow the Spring Boot 2.0 Migration Guide to fix the most common problems.

    • If you want to use the behaviour of Edison 1.x, which hosts all management endpoints below /internal, you have to configure management.endpoints.web.base-path=/internal in your application.yml
  • Remove dependencies to the edison-aws Project, which will be deprecated some time in the future. Necessary functionality was transferred to a submodule of edison-microservice (named edison-aws).

  • If you have used gradlew bootRepackage for packaging your application so far, you have to migrate this to gradlew bootJar.

  • Refactor calls made through the AWS SDK, which got updated in the process of the new major version of edison and this will most probably break prior code that relied on the AWS SDK.

  • To use @Timed-Annotations, you need to configure Micrometer accordingly. See the following Example for a configuration that covers the annotation and naming of all metrics:

      public class MicrometerConfiguration {
          public PrometheusNamingConvention prometheusNamingConvention() {
              return new PrometheusNamingConvention();
          public MeterRegistryCustomizer<MeterRegistry> metricsCommonTags(@Value("${service.vertical}") final String vertical,
                                                                          @Value("${}") final String serviceName,
                                                                          final PrometheusNamingConvention prometheusNamingConvention) {
              return registry -> registry
                      .namingConvention(new NamingConvention() { 
                          // Set naming convention that gets applied to all metrics, in this  example explicitly using a Prometheus naming convention
                          public String name(final String name, final Meter.Type type, final String baseUnit) {
                              return"%s.%s.%s", vertical, serviceName, name), type, baseUnit);
                      .meterFilter(new MeterFilter() { // Configure generally applicable configurations, like percentiles
                          public DistributionStatisticConfig configure(final Meter.Id id,
                                                                       final DistributionStatisticConfig config) {
                              return config.merge(DistributionStatisticConfig.builder()
                                      .percentiles(0.5, 0.9, 0.95, 0.98, 0.99, 0.999)
          // Create a `TimedAspect` to enable `@Timed`-Annotations
          public TimedAspect timedAspect(final MeterRegistry registry) {
              return new TimedAspect(registry);


Edison Modules:

  • edison-aws: AWS related configuration and togglz settings
  • edison-core: Main library of Edison microservices.
  • edison-jobs: Optional module providing a simple job library.
  • edison-mongo: Auto-configuration for MongoDB repositories plus implementation of MongoJobRepository and Togglz StateRepository.
  • edison-oauth: Auto-configuration for OAuth Public Key repositories with autofetching and a simple JWT Token Validation.
  • edison-togglz: Optional support for feature toggles for Edison microservices based on Togglz.
  • edison-testsupport: Test support for feature toggles plus utilities.
  • edison-validation: Optional module for validation in Spring with a specific response format.


  • example-status: Service only relying on edison-core to show the usage of health and status features.
  • example-jobs: Edison service using edison-jobs to run background tasks.
  • example-togglz: Example using `edison-togglz´ to implement feature toggles.
  • example-togglz-mongo: Same edison-toggz, but with a MongoDB configuration to auto-configure persistence of feature toggles.


Make sure you have Java 11 or later and gradle 6.x installed on your computer.

There are a few examples that may help you to start your first microservice based on Edison and Spring Boot. Because Spring Boot itself has some complexity, it is recommended to first read it's documentation before starting with Edison.

The examples can be started with gradle:

gradle examples:example-status:bootRun
gradle examples:example-jobs:bootRun
gradle examples:example-togglz:bootRun
gradle examples:example-togglz-mongo:bootRun

Open in your browser http://localhost:8080/

Note: Every example is configured to use port 8080, so make sure to run only one example at a time or to reconfigure the ports.
