Java Spring application in PaaS-platform Heroku in 14 minutes

Hello!
I continue the series of publications on the project
Maven / Spring / Security / JPA (Hibernate) / Rest (Jackson) / Bootstrap (CSS) / jQuery + plugins
( source code on github ).

Previous publications:

• In the wake of Spring Pet Clinic. Maven / Spring Context / Spring Test / Spring ORM / Spring Data JPA
• We test Spring Rest controllers: simpler, shorter, more reliable. Spring Security Test + JSON Matcher
• Spring Security 4 + CSRF (adding a cross-site request forgery protection project to Spring)

The final part of the project: deploy to Heroku cloud PaaS platform

Instructions on steps (from video):

1. Make an account on Heroku ;
2. Create a Personal App in it and connect it to your project in GitHub;
3. Add Add-ons: database;
4. Create a Data Source to the database in IDEA, take the base credit from the environment variable DATABASE_URL;
5. In DataSource -> Advanced add ssl = true, sslfactory = org.postgresql.ssl.NonValidatingFactory;
6. Run the sql-script initialization to the database Heroku;
7. Configure Heroku in the project:
   
   • Add a dependency on a webapp-runner to pom.xml;
   • Set Maven profiles to run in Heroku in settings.xml;
   • Create a procfile ;
   • Configure the Spring dataSource for the Heroku database ;
8. Test Heroku actions locally via .bat (.sh) ;
9. Make commit + push to GitHub;
10. Optional:
    
    • To view the application log install Heroku Toolbelt ;
    • If the application has external resources available via the environment variable, configure it in Heroku: Settings-> Config Vars-> PROJECT_ROOT = / app
    • Configure ERROR_PAGE_URL
    • Connect Heroku to IDEA : add plugin and generated keys
11. Make manual deploy from GitHub to Heroku;
12. Run in browser: [your_application_name] .herokuapp.com
13. Do not forget to congratulate yourself: now the whole world will see your application :)

Well and the last: some resources on Heroku and PaaS comparison

• Java PaaS shootout

Thanks for attention!
