Naive implementation of pure OOP ideas of Yegor Bugayenko.

Warehouse is web app with REST interfaces and without ORM. Because as everybody knows ORM Is an Offensive Anti-Pattern.

How to run

First of all you'll need to init H2 database schema. You can try to do it this way:

• In Intellij Idea create embeded H2 datasource
• Set path to /tmp/warehouse
• Set password to sa

Your connection URL should look like this: jdbc:h2:/tmp/warehouse

Now fill you DB with db_init.sql script from project resources folder.

Now you can run sample warehouse app from command line:

$ mvn clean integration-test -Phit-refresh -Dport=8080

Now in browser open localhost:8080/categories to see list of categories.

• localhost:8080/categories

  • GET to list all categories
  • POST/PUT{name:foo, parent_id=1} to create new category. Parent ID is optional here.

• /categories/ID
