# Spring Boot application template



[![Build Status](https://travis-ci.org/hmcts/spring-boot-template.svg?branch=master)](https://travis-ci.org/hmcts/spring-boot-template)



## Purpose



The purpose of this template is to speed up the creation of new Spring applications within HMCTS

and help keep the same standards across multiple teams. If you need to create a new app, you can

simply use this one as a starting point and build on top of it.



## 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](https://github.com/hmcts/reform-api-docs#publish-swagger-docs))

 * code quality tools already set up

 * 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:



    ```bash

      ./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:



    ```bash

      ./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 and use the next generation



## Building and deploying the application



### Building the application



The project uses [Gradle](https://gradle.org) 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:



```bash

  ./gradlew build

```



### Running the application



Create the image of the application by executing the following command:



```bash

  ./gradlew assemble

```



Create docker image:



```bash

  docker-compose build

```



Run the distribution (created in `build/install/spring-boot-template` directory)

by executing the following command:



```bash

  docker-compose up

```



This will start the API container exposing the application's port

(set to `4550` in this template app).



In order to test if the application is up, you can call its health endpoint:



```bash

  curl http://localhost:4550/health

```



You should get a response similar to this:



```

  {"status":"UP","diskSpace":{"status":"UP","total":249644974080,"free":137188298752,"threshold":10485760}}

```



### Alternative script to run application



To skip all the setting up and building, just execute the following command:



```bash

./bin/run-in-docker.sh

```



For more information:



```bash

./bin/run-in-docker.sh -h

```



Script includes bare minimum environment variables necessary to start api instance. Whenever any variable is changed or any other script regarding docker image/container build, the suggested way to ensure all is cleaned up properly is by this command:



```bash

docker-compose rm

```



It clears stopped containers correctly. Might consider removing clutter of images too, especially the ones fiddled with:



```bash

docker images



docker image rm 

```



There is no need to remove postgres and java or similar core images.
