Override Spring properties without using profiles

Question

I have few property files(application.properties) which contains both custom and spring configuration under classpath, i want load these properties based on system variables. I used PropertySourcesPlaceholderConfigurer to load properties as below.

@Bean
    public PropertySourcesPlaceholderConfigurer loadResources() {
PropertySourcesPlaceholderConfigurer resourceConfigurer = new PropertySourcesPlaceholderConfigurer();
        resourceConfigurer.setLocations(new ClassPathResource("file1"), new ClassPathResource("file2"));
return resourceConfigurer ;
}

But it failed to override spring configuration(spring configurations added in application.properties), i want to override these files after spring picks application.properties file. Idea is to override spring configuration programmatically. How this can be achieved?

Why? This will add only additional processing to the application and indeed will not override things (it might even break the Spring Boot processing). Run the application with --spring.config.location or --spring.config-additional-location instead of trying this. See the documentation on how to load additional files. — M. Deinum
