JHipster blueprint, a Jhipster blueprint to have a different database sequence for each database
Introduction
This is a JHipster blueprint, that is meant to be used in a JHipster application.
How it works
Insead of using the same hibernate_sequence
for all entities this blueprint allows to have a single sequence for each hibernate entity.
Default jhipster code:
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sequenceGenerator")
@SequenceGenerator(name = "sequenceGenerator")
private Long id;
Blueprint code:
@Id
@GeneratedValue(strategy = GenerationType.SEQUENCE, generator = "sequenceGenerator")
@SequenceGenerator(name = "sequenceGenerator", sequenceName="project_seq")
private Long id;
The sequence is also added into the liquibase xml changeset file
Prerequisites
As this is a JHipster blueprint, we expect you have JHipster and its related tools already installed:
Installation
With Yarn
To install this blueprint:
yarn global add generator-jhipster-dbsequences
To update this blueprint:
yarn global upgrade generator-jhipster-dbsequences
With NPM
To install this blueprint:
npm install -g generator-jhipster-dbsequences
To update this blueprint:
npm update -g generator-jhipster-dbsequences
Usage
To use this blueprint, run the below command
jhipster --blueprint dbsequences
Running local Blueprint version for development
During development of blueprint, please note the below steps. They are very important.
- Link your blueprint globally
Note: If you do not want to link the blueprint(step 3) to each project being created, use NPM instead of Yarn as yeoman doesn't seem to fetch globally linked Yarn modules. In the other hand this means you have to use NPM in all the below steps as well.
cd dbsequences
npm link
- Link a development version of JHipster to your blueprint (optional: required only if you want to use a non-released JHipster version, like the master branch or your own custom fork)
You could also use Yarn for this if you prefer
cd generator-jhipster
npm link
cd dbsequences
npm link generator-jhipster
- Create a new folder for the app to be generated and link JHipster and your blueprint there
mkdir my-app && cd my-app
npm link generator-jhipster-dbsequences
npm link generator-jhipster (Optional: Needed only if you are using a non-released JHipster version)
jhipster -d --blueprint dbsequences
