如何在不使用xml配置的情况下禁用Spring引导中的调试消息？

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class YourApplication {

    public static void main(String[] args) {
        SpringApplication app = new SpringApplication(YourApplication.class);
        app.setLogStartupInfo(false);
        app.run(args);
    }
}
