下载Spring-Boot源码,目录结构spring-boot-2.1.0.M2\spring-boot-2.1.0.M2\spring-boot-project\spring-boot\src\main\java\org\springframework\boot
Banner为接口具体实现类二个,https://docs.spring.io/spring-boot/docs/2.0.5.RELEASE/api/
一个存放图片资源,一个存放资源。
package com.jachs.jurisdiction.Jurisdiction; import java.io.BufferedInputStream;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileReader; import org.springframework.boot.ImageBanner;
import org.springframework.boot.ResourceBanner;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.core.io.InputStreamResource; @SpringBootApplication
public class JurisdictionApplication{
/*
@Override
protected SpringApplicationBuilder configure(SpringApplicationBuilder builder) {
System.out.println("in");
try {
builder.banner(new ImageBanner(new InputStreamResource(new FileInputStream("C:\\Users\\Jachs\\Desktop\\a.png"))));
} catch (FileNotFoundException e) {
e.printStackTrace();
}
return builder.sources(JurisdictionApplication.class);
}
*/
public static void main(String[] args) throws FileNotFoundException {
// SpringApplication.run(LoginAction.class, args);
// SpringApplication.run(JurisdictionApplication.class, args);
SpringApplication application = new SpringApplication(JurisdictionApplication.class);
application.setBanner(new ImageBanner(new InputStreamResource(new FileInputStream("C:\\Users\\Jachs\\Desktop\\a.png"))));
// application.setBanner(new ResourceBanner(new InputStreamResource(new FileInputStream("C:\\Users\\Jachs\\Desktop\\s.txt"))));
application.run(args);
}
}
实现ImageBanner是打印的为图片二进制,为实现自己独特的打印采用ResourceBanner指定一个文本写入类容初始化时打印。

默认打印采用的是SpringBootBanner代码如下，可以自己改造

不想显示初始化Banner时。
application.setBannerMode(Mode.OFF);
Mode说明
该枚举三个CONSOLE打印到控制台,LOG打印到log日志,OFF不打印。
