跟杨春娟学SpringBoot笔记：Spring Boot扩展启动行为-改变启动Banner

完成：第一遍

1.如何改变启动Banner?

可以使用文件的方式来设置Banner

可以从网站拷贝以ASCII码来展示Banner

第一种方式：在SpringBootDemoProjectApplication 通过setBanner()来设置Banner

src/main/resources下有个banner.txt

package com.springboot.demo.SpringBootDemoProject;import org.springframework.boot.Banner.Mode;import org.springframework.boot.ResourceBanner;import org.springframework.boot.SpringApplication;import org.springframework.boot.autoconfigure.SpringBootApplication;import org.springframework.boot.context.properties.EnableConfigurationProperties;import org.springframework.context.annotation.PropertySource;import org.springframework.core.io.ClassPathResource;import com.springboot.demo.SpringBootDemoProject.configuration.AWSConfigBean;import com.springboot.demo.SpringBootDemoProject.configuration.RandomConfigBean;@SpringBootApplication@PropertySource("classpath:config.properties")@EnableConfigurationProperties({
   AWSConfigBean.class, RandomConfigBean.class})public class SpringBootDemoProjectApplication {
   	public static void main(String[] args) {
   		SpringApplication.run(SpringBootDemoProjectApplication.class, args);			//SpringApplication springApplication = new SpringApplication(SpringBootDemoProjectApplication.class);				//关闭启动Banner		//springApplication.setBannerMode(Mode.OFF);				//设置启动banner		/*		 * springApplication.setBanner(new ResourceBanner(new		 * ClassPathResource("banner.txt")));		 * springApplication.setBannerMode(Mode.CONSOLE);		 * 		 * springApplication.run(args);		 */	}}

第二种方式：在ApplicationContext.properties中

设置Banner

spring.banner.charset=UTF-8spring.banner.location=classpath:banner.txtspring.banner.image.location=classpath:banner.jpgspring.banner.image.width=76spring.banner.image.invert=false

关闭Banner
