1，在测试禁用banner的时候启动springboot项目报了上面的错误，以下是启动类的代码：

@SpringBootApplication
public class Springbootday011Application {
	public static void main(String[] args) {
		//SpringApplication.run(Springbootday011Application.class, args);
		SpringApplicationBuilder builder = new SpringApplicationBuilder();
		builder.bannerMode(Banner.Mode.OFF).run(args);
	}
}

原因：忘了给SpringApplicationBuilder传一个sources参数了（当前类的对象），以此参数来创建一个SpringApplication实例。上面代码应改为

@SpringBootApplication
public class Springbootday011Application {
	public static void main(String[] args) {
		//SpringApplication.run(Springbootday011Application.class, args);
		SpringApplicationBuilder builder = new SpringApplicationBuilder(Springbootday011Application.class);
		builder.bannerMode(Banner.Mode.OFF).run(args);
	}
}

其实SpringApplication.run(Springbootday011Application.class, args);底层也是通过sources来创建SpringApplication实例的
