Running a Spring Boot Application with fixed locale

Question

I am working on a server application without a user frontend. To ensure that all parts of the application will generate only English message I would like to ensure that the application will use only a specific locale.

After reading the docs and some googling I came to the conclusion that I have to do the following:

1. Setting the locale programmatically in the main method via Locale.setDefault(Locale.ENGLISH);

2. Provide a bean instance of FixedLocaleResolver as locale resolver for the application.

Is this correct or this there a better way to achive my goal?

Answer 1

you can put

spring.mvc.locale=en_EN
spring.mvc.localeResolver=fixed

in your application.properties or application.yml(of course in yaml format).

Spring will automatically read those properties.

I am not aware of any other better way.

Can this also be done for session locale or only for fixed locale? – Marduk

Answer 2

Since SpringBoot 2.4.0 use:

spring.web.locale=en_EN
spring.mvc.localeResolver=fixed

Answer 3

In application.yml:

spring:
  web:
    locale: en_EN
    locale-resolver: fixed

This combination works well for me in Spring Boot 3.0 . Thanks Ashley! – Culinarian
