啓動圖案
Spring Boot在啓動的時候會顯示一個默認的Spring的圖案,對應的類爲SpringBootBanner。markdown
. ____ _ __ _ _ /\\ / ___'_ __ _ _(_)_ __ __ _ \ \ \ \ ( ( )\___ | '_ | '_| | '_ \/ _` | \ \ \ \ \\/ ___)| |_)| | | | | || (_| | ) ) ) ) ' |____| .__|_| |_|_| |_\__, | / / / / =========|_|==============|___/=/_/_/_/ :: Spring Boot :: (v1.5.6.RELEASE)
圖案輸出有如下幾種模式,默認是CONSOLE的,即只打印到控制檯,也能夠輸出到日誌文件。app
enum Mode { /** * Disable printing of the banner. */ OFF, /** * Print the banner to System.out. */ CONSOLE, /** * Print the banner to the log file. */ LOG }
關閉圖案
@SpringBootApplication public class Application { public static void main(String[] args) { new SpringApplicationBuilder(Application.class).bannerMode(Banner.Mode.OFF) .run(args); } }
定製圖案
很簡單,只要在classpath目錄下建立banner.txt便可,把圖案放入該文件就行,這是Spring Boot默認的圖案位置,Spring Boot會自動加載該文件顯示圖案。ide

也能夠使用圖片,更詳細的能夠研究Banner接口及其子類,不過這也沒什麼卵用,有興趣的能夠深刻了解下。網站
固然也支持經過application配置文件來定製圖案。ui
# BANNER banner.charset=UTF-8 # Banner file encoding. banner.location=classpath:banner.txt # Banner file location. banner.image.location=classpath:banner.gif # Banner image file location (jpg/png can also be used). banner.image.width= # Width of the banner image in chars (default 76) banner.image.height= # Height of the banner image in chars (default based on image height) banner.image.margin= # Left hand image margin in chars (default 2) banner.image.invert= # If images should be inverted for dark terminal themes (default false)
