How to generate current year in spring boot properties

Question

In this article we can see how to generate random properties in application.properties . Is there also some way how to generate some other properties like current year using java code in application.properties ?

I tried this:

config.current-year=${LocalDate.now.getYear}

but it throws exception:

Caused by: java.lang.NumberFormatException: For input string: "${LocalDate.now.getYear}"

UPDATE:

after iamrajshah answer I see random represent class RandomValuePropertySource which is loaded in this way:

protected void addPropertySources(ConfigurableEnvironment environment,
        ResourceLoader resourceLoader) {
    RandomValuePropertySource.addToEnvironment(environment);
    new Loader(environment, resourceLoader).load();
}

so all I need is just to override (Idk now) this function and add there my class which I can use.

Answer 1

You can check this out
application.properties are like registering similar to *.xml in previous version of spring.
Spring boot provides RandomValuePropertySource which used to generate values.
NOT any other classes supports in this file.
