A quick example of getting Oracle JDBC to work with springboot RESTful application

Springboot with Oracle DB Example

Quick example of using springboot to write a quick REST API to access some stuff in an Oracle database.

Steps to make this garbage work

Prereqs

1. Java 8
2. Maven (because reasons)
3. Vagrant: https://www.vagrantup.com/
4. Clone this repo (duh)

Install/Configure Oracle express

1. Oracle xe installer for linux (I don't care if you're running linux or not, this guy is going in a VM): http://www.oracle.com/technetwork/database/database-technologies/express-edition/downloads/index.html
2. Move that guy to spring-boot-oracle-example/oracle-installer
3. vagrant up (in the spring-boot-oracle-example dir)
4. Congrats, oracle xe is installed(ish) on this VM
5. vagrant ssh
6. sudo -i (act as root)
7. You'll note from the step above after running vagrant up you'll see a message, something like ==> default: You must run '/etc/init.d/oracle-xe configure' as the root user to configure the database. So yeah.. do that.
8. Use the default ports. And take not of the password you provide.
9. . /u01/app/oracle/product/11.2.0/xe/bin/oracle_env.sh - Set env variables using the script provided from Oracle. This is needed to connect using their sql client.
10. sqlplus /nolog
11. connect sys as sysdba
12. Enter the password you created during config
13. start /vagrant/create_sql_user_and_tables.sql

Oracle JDBC Driver shenanigans

1. Download the JDBC driver: http://www.oracle.com/technetwork/database/features/jdbc/index-091264.html
2. Here's where things get interesting. Apparently gradle can't load this jar from a flatFile repository. So the workaround is to create a local maven repository and load this 1 jar into it.
3. cd to the directory where the ojdbc jar is located
4. mvn install:install-file -Dfile=ojdbc6.jar -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.4 -Dpackaging=jar
5. In the above command make sure to adjust the file, artifactId, and version to match the driver you downloaded.
6. If a different version from the one above was used adjust build.gradle

Run it!

1. ./gradlew bootRun
2. http://localhost:8080/users
