Priority of Various Sources in PropertySources

Question

Spring has introduced a new annotation @PropertySources for all classes marked as @Configuration since 4.0. It takes different @PropertySource as argument.

@PropertySources({
    @PropertySource("classpath:application.properties"), @PropertySource("file:/tmp/application.properties")})

What I am interested is knowing is the ordering in case of conflict in values for the same key present in multiple properties file. I have not seen any documentation related to this that specifies an ordering. I have tries it multiple times and found that the PropertySource mentioned later is overwriting the value present in PropertySource mentioned before. But, how to be sure?

Answer 1

HL'REB is right. "Win" the parameter from the last properties file. However, application.properties overrides all values. Checked for SPRING 5.1.6.
