Get spring application environment in thymeleaf

My Spring Boot application runs with 3 configurations:

- application.properties --> for development environment
- application-test.properties --> for test environment
- application-production.properties --> for production environment

How is it possible to get in thymeleaf environment the application is running?

I need to include the Google Analytics code only in production environment.

You can do the following if you only have one profile active at a time.

<div th:if="${@environment.getActiveProfiles()[0] == 'production'}">
This is the production profile - do whatever you want in here
</div>

The code above is based on the fact that the Thymeleaf's Spring dialect lets you access beans using the `@` symbol. And of course the `Environment` object is always available as a Spring bean.

Also note that `Environment` has the method `getActiveProfiles()` which returns an array of Strings (that is why `[0]` is used in my answer) which we can call using standard Spring EL.

If more than one profiles are active at a time, a more robust solution would be to use Thymeleaf's `#arrays` utility object in order to check for the presence of the string `production` in the active profiles. The code in that case would be:

<div th:if="${#arrays.contains(@environment.getActiveProfiles(),'production')}">
This is the production profile
</div>

Simply add this class which allows to set global variables for views:

@ControllerAdvice
public class BuildPropertiesController {

@Autowired
private Environment env;

@ModelAttribute("isProd")
public boolean isProd() {
return Arrays.asList(env.getActiveProfiles()).contains("production");
}
}

And then use `${isProd}` variable in your thymeleaf file:

<div th:if="${isProd}">
This is the production profile
</div>

Or you can set active profile name as a global variable:

@ControllerAdvice
public class BuildPropertiesController {

@Autowired
private Environment env;

@ModelAttribute("profile")
public String activeProfile() {
return env.getActiveProfiles()[0];
}
}

And then use `${profile}` variable in your thymeleaf file (if you have one active profile):

<div>
This is the <span th:text="${profile}"></span> profile
</div>
