How to move messages.properties files into a separate folder?

Question

Is it possible to place messages.properties and all other locale-specific messages_xx.properties files in a sub-folder of the resources folder in a Spring Boot application? For example to move them all in langs folder:

─── 🗁 src
   └─── 🗁 main
       ├─── 🗁 java
       └─── 🗁 resources
           ├─── 🗁 langs
           │   ├─── messages.properties
           │   └─── messages_fa.properties
           └─── ...

Answer 1

Yes, it is possible. You just need to add this property in the application.properties or application.yml file:

spring.messages.basename=langs.messages

Here langs is the name of the folder and messages is the base name of files.
