I'm upgrading my application to the new SpringBoot version. I'm actually in 2.3.5 using properties files like that : application-{profilename}.(properties/yaml)
I read those documentation : https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-Config-Data-Migration-Guide https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-Config-Data-Migration-Guide
My pom is this one :

In my application.properties :
spring.config.use-legacy-processing=true
In my application-local.properties :
# DATASOURCE (DataSourceAutoConfiguration & DataSourceProperties)
spring.main.banner-mode=off
# Hibernate ddl auto (create, create-drop, validate, update)
spring.jpa.hibernate.ddl-auto = update
# MANY OTHERS
When i start the app, it lauch without taking the properties !
I tried to apply spring.profiles.active=local in my application.properties but without success !
In vm argument i have this : -Dspring.profiles.active=local
With and without it just does not work..
I was not having any problem with 2.3.5.
spring.main.banner-mode=off works
How i see that properties are not loaded :
I have spring.main.banner-mode=off and the banner is displayed so something wrong.
Datasource properties are not loaded too..
Refer to : https://stackoverflow.com/questions/65008209/upgrade-springboot-2-3-5-to-2-4-0
Thanks for help, i'm sure it can help a lot of people !
For information in spring tool suite 4 4.5.0:
spring.config.use-legacy-processing=true is an unknow property

Are there comments in your application.properties file? This could be related to #24158
Comment From: snicoll
Indeed, you may confirm that quickly by running this app against 2.4.1-SNAPSHOT.

@bclozl Hi ! Thanks bro !! It was a shit bug ! 2.4.1-SNAPSHOT is actually not available in Maven :(
I close it because # was the problem !
Comment From: bclozel
@Whisper40 It's not on Maven Central as it's not a public release, but a SNAPSHOT version. You can add our snapshot repo to your build configuration. You can get the build snippet by generating a new Spring Boot project on https://start.spring.io/ and selecting 2.4.1-SNAPSHOT.

@bclozel Thanks for the information :) I just tested with :: Spring Boot :: (v2.4.1-SNAPSHOT) The problem of " # " in properties is again present on my side ( yes i clean and then update project and release too) ( i have my lines with # )
Example :
#OpenAPI - Swagger UI
springdoc.swagger-ui.path=/swagger-ui.html
#Log
logging.level.org.hibernate.SQL=ERROR
logging.level.org.hibernate.type=ERROR
#TimeZone
spring.jpa.properties.hibernate.jdbc.time_zone = Europe/Paris
spring.jackson.time-zone: Europe/Paris

Can you create a small, sample application that reproduces the issue? Creating a small project on GitHub or uploading it here would be perfect. You can start from a fresh project on start.spring.io and add properties/specific things to your application until you can reproduce the issue.
Thanks!

Just downloaded a default project and added properties. I run it with the same Vm argument -Dspring.profiles.active=local
I'm not having the problem with 2.4.1-SNAPSHOT with default project
But with mine yes, really strange, will try to investigate
Other thing : With default project and mine : https://prnt.sc/vqkwes
[Update] Working with 2.4.1-SNAPSHOT and # in properties with my project. I have got a problem of update project But the red thing in pom is always present -> Red thing does not appear with SpringToolSuite 4.5.0 -> Appears with 4.9.0

Thanks for the follow-up. We can't unfortunately provide you support with the error in your IDE. Please follow-up on StackOverflow for that.

Hi everyone. I have the same problem. I updated Spring Boot from 2.3.6.RELEASE to 2.4.0 and it seems that application.properties is not loading. I have the following in application.properties:
empleosapp.ruta.imagenes=c:/empleos/img-vacantes/
After running, I got the error: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'vacantesController': Injection of autowired dependencies failed; nested exception is java.lang.IllegalArgumentException: Could not resolve placeholder 'empleosapp.ruta.imagenes' in value "${empleosapp.ruta.imagenes}"
Using 2.3.6.RELEASE it works fine
Thanks!

This doesn't seem to be related to this issue. Please create a new issue with a sample project reproducing the problem, as the current description doesn't provide enough information. Thanks
