[JAVA] In SpringBoot 2.3.0 or later, the placeholder used for the value of @PropertySource fails to be resolved.


The title is as it is. In SpringBoot 2.3.0 or later, if you use a placeholder like classpath: /something-config-${spring.profiles.active} .yml to specify the value of @ PropertySource, you will not be able to resolve it and an exception will occur. appear. The latest version of Boot today is 2.3.1.



@ConfigurationProperties(prefix = "something")
@PropertySource(value = {"classpath:/something-config.yml","classpath:/something-config-${spring.profiles.active}.yml"}, factory = YamlPropertySourceFactory.class)
public class SomethingConfig {

    private String setting1;
    private String setting2;


Caused by: java.lang.IllegalArgumentException: Could not resolve placeholder 'spring.profiles.active' in value "classpath:/somethign-config-${spring.profiles.active}.yml"


I used 2.2 series for the time being.
