Common application properties
JHipster generates a Spring Boot application, and can be configured using the standard Spring Boot properties mechanism.
Those properties are configured at generation-time by JHipster, and often have different values in development and production modes: learn more about this in our Profiles documentation.
In a JHipster application, there are three kinds of properties:
- Spring Boot standard application properties
- JHipster application properties
- Application-specific properties
Like any Spring Boot application, JHipster allows you to configure any standard Spring Boot application property.
JHipster provides specific application properties, which come from the JHipster server-side library. Those properties are standard for all JHipster projects, but some of them only work depending on what you selected when you built your application: for example the
jhipster.cache.hazelcast key only works if you selected Hazelcast as your 2nd-level Hibernate cache.
Those properties are configured using the
Here is a documentation for those properties:

Your generated application can also have its own Spring Boot properties. This is highly recommended, as it allows type-safe configuration of the application, as well as auto-completion and documentation within an IDE.
JHipster has generated a
ApplicationProperties class in the
config package, which is already preconfigured, and it is already documented at the bottom the
application-prod.yml files. All you need to do is code your own specific properties.
