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;@SpringBootApplicationpublic 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。
