Spring Boot application template

Purpose

The purpose of this template is to speed up the creation of tests for the Functional, Integration and Smoke Tests.

What's inside

The template is a working application with a minimal setup. It contains:

• application skeleton
• setup script to prepare project
• common plugins and libraries
• docker setup
• swagger configuration for api documentation (see how to publish your api documentation to shared repository)
• code quality tools already set up
• integration with Travis CI
• Hystrix circuit breaker enabled
• MIT license and contribution information
• Helm chart using chart-java.

The application exposes health endpoint (http://localhost:4550/health) and metrics endpoint (http://localhost:4550/metrics).

Plugins

The template contains the following plugins:

• checkstyle

  https://docs.gradle.org/current/userguide/checkstyle_plugin.html

  Performs code style checks on Java source files using Checkstyle and generates reports from these checks. The checks are included in gradle's check task (you can run them by executing ./gradlew check command).

• pmd

  https://docs.gradle.org/current/userguide/pmd_plugin.html

  Performs static code analysis to finds common programming flaws. Included in gradle check task.

• jacoco

  https://docs.gradle.org/current/userguide/jacoco_plugin.html

  Provides code coverage metrics for Java code via integration with JaCoCo. You can create the report by running the following command:

    ./gradlew jacocoTestReport

  The report will be created in build/reports subdirectory in your project directory.

• io.spring.dependency-management

  https://github.com/spring-gradle-plugins/dependency-management-plugin

  Provides Maven-like dependency management. Allows you to declare dependency management using dependency 'groupId:artifactId:version' or dependency group:'group', name:'name', version:version'.

• org.springframework.boot

  http://projects.spring.io/spring-boot/

  Reduces the amount of work needed to create a Spring application

• org.owasp.dependencycheck

  https://jeremylong.github.io/DependencyCheck/dependency-check-gradle/index.html

  Provides monitoring of the project's dependent libraries and creating a report of known vulnerable components that are included in the build. To run it execute gradle dependencyCheck command.

• com.github.ben-manes.versions

  https://github.com/ben-manes/gradle-versions-plugin

  Provides a task to determine which dependencies have updates. Usage:

    ./gradlew dependencyUpdates -Drevision=release

Setup

Located in ./bin/init.sh. Simply run and follow the explanation how to execute it.

Notes

Since Spring Boot 2.1 bean overriding is disabled. If you want to enable it you will need to set spring.main.allow-bean-definition-overriding to true.

JUnit 5 is now enabled by default in the project. Please refrain from using JUnit4 (except for libraries not able to support Junit5 like Serenity) and use the next generation

Building and deploying the application

Building the application

The project uses Gradle as a build tool. It already contains ./gradlew wrapper script, so there's no need to install gradle.

To build the project execute the following command:

  ./gradlew build

Running the Functional Tests

Change Directory to the root folder of the Project:

Run the following command

  ./gradlew clean functional
