How to configure the Spring java environment without the locations configuration property?

Question

I am creating a class called FileConfig with the following annotation:

@ConfigurationProperties(locations = { "classpath:application.properties" , "${file.config.location}" })

The following line exists within 'application.properties':

file.config.location = fileinfo.yaml

Apparently, my compiler says, that the locations property has deprecated in favor of configuring the environment directly with additional locations. Can someone please help me how to configure the environment so that the variables in FileConfig are initialized using the contents of 'fileinfo.yaml' file

Using @PropertySource("classpath:testapplication.properties") instead of using the above line of code produces an error.

If I understand your question correctly, you specify the location of fileInfo.yaml file in your application.properties file. And this value should be set as location of your property class FileConfig .

I think thats not possible because SpEL expressions are not evaluated.

Here the part of the java doc from @ConfigurationProperties :

Annotation for externalized configuration. Add this to a class definition or a @Bean method in a @Configuration class if you want to bind and validate some external Properties (eg from a .properties file).

Note that contrary to @Value, SpEL expressions are not evaluated since property values are externalized.
