Usage

(1) use toml file as property source

@Configuration
@PropertySource(value = "classpath:/config.toml", factory = TomlPropertySourceFactory.class)
public class ApplicationConfig {
    // ...
}

(2) use yaml file as property source

@Configuration
@PropertySource(value = "classpath:/config.yaml", factory = YamlPropertySourceFactory.class)
public class ApplicationConfig {
    // ...
}

(3) use hocon file as property source (highly recommended)

@Configuration
@PropertySource(value = "classpath:/config.conf", factory = HoconPropertySourceFactory.class)
public class ApplicationConfig {
    // ...
}

(4) use AbstractConventionEnvironmentPostProcessor load property-source file(s) implicitly

package my.project;

public class MyEnvironmentPostProcessor extends AbstractConventionEnvironmentPostProcessor {

    @Override
    protected String getName(ConfigurableEnvironment environment, SpringApplication application) {
        return "property-source";
    }

    @Override
    protected String[] getLocationsPrefix(ConfigurableEnvironment environment, SpringApplication application) {
        return new String[]{
                "classpath:my-project"
        };
    }
}

DO NOT forget to register it. In your classpath:/META-INF/spring.factories:

org.springframework.boot.env.EnvironmentPostProcessor=my.project.MyEnvironmentPostProcessor

Now, file(s) will be loaded if exists.

• classpath:my-project.conf
• classpath:my-project.toml
• classpath:my-project.yml
• classpath:my-project.yaml
• classpath:my-project.properties
• classpath:my-project.xml (also properties)

Also, file(s) will be loaded if exists and myprofile profile is active.

• classpath:my-project-myprofile.conf
• classpath:my-project-myprofile.toml
• classpath:my-project-myprofile.yml
• classpath:my-project-myprofile.yaml
• classpath:my-project-myprofile.properties
• classpath:my-project-myprofile.xml (also properties)
