Found an solution:

first create a class and add @ConfigurationProperties

@ConfigurationProperties(prefix = "asdf", locations = "file:conf/aaa.properties")
public class ASDF {
    private String name;   

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }
}

Please noted in locations, i use file, not classpath.

then in your application class, add @EnableConfigurationProperties

@SpringBootApplication
@EnableConfigurationProperties({ASDF.class, BBB.class})
public class InitialBeanTestApplication {

    public static void main(String[] args) {
        SpringApplication.run(InitialBeanTestApplication.class, args);
    }
}

then you can read config file in the conf folder
