Java精選面試題（微信小程序）：5000+道面試題和選擇題，包含Java基礎(chǔ)、并發(fā)、JVM、線程、MQ系列、Redis、Spring系列、Elasticsearch、Docker、K8s、Flink、Spark、架構(gòu)設(shè)計(jì)、大廠真題等，在線隨時(shí)刷題！
1、什么是 banner.txt？
當(dāng)你啟動(dòng) Spring Boot 應(yīng)用時(shí)，控制臺(tái)會(huì)打印出一個(gè)默認(rèn)的 Spring Boot Banner（比如啟動(dòng)LOGO）。這個(gè)內(nèi)容來(lái)自resources目錄下的banner.txt文件。你可以通過(guò)這個(gè)文件自定義你想展示的 ASCII 圖案、版本號(hào)、提示文字等。
2、創(chuàng)建或修改 banner.txt 2.1、文件位置：
在你的 Spring Boot 項(xiàng)目中，進(jìn)入src/main/resources目錄下，新建或編輯：
src/main/resources/banner.txt
2.2. 內(nèi)容示例（純色風(fēng)格 + 啟動(dòng)信息）：
=========================================== == AbsWeb 啟動(dòng)成功！ == == 端口：${server.port} == == 環(huán)境：${spring.profiles.active} == == 時(shí)間：${date} == ===========================================你可以使用 Spring Boot 提供的一些占位符變量：
占位符
描述
${application.version}
項(xiàng)目的 MANIFEST.MF 版本
${application.formatted-version}
格式化版本號(hào)
${spring-boot.version}
Spring Boot 版本
${server.port}
當(dāng)前端口號(hào)
${spring.profiles.active}
當(dāng)前激活的配置環(huán)境
${date}
啟動(dòng)時(shí)間
${AnsiColor.NAME}
控制臺(tái)顏色（如 GREEN、RED）
3、加點(diǎn)顏色和風(fēng)格（可選）
Spring Boot 支持 ANSI 顏色，在支持的終端中會(huì)顯示彩色效果：
${AnsiColor.BRIGHT_CYAN} =========================================== == AbsWeb 啟動(dòng)成功！ == == 端口：${server.port} == == 環(huán)境：${spring.profiles.active} == == 時(shí)間：${date} == =========================================== ${AnsiColor.DEFAULT}啟動(dòng)項(xiàng)目時(shí)，你會(huì)看到類似輸出：
=========================================== == AbsWeb 啟動(dòng)成功！ == == 端口：8082 == == 環(huán)境：test == == 時(shí)間：2025-06-13 16:52:10 == ===========================================提供幾個(gè)網(wǎng)站可以自己去生成圖案:

1、禁用 Spring Boot 的默認(rèn) banner：
在你的配置文件（如application.yml或application.properties）中添加：
yml文件：
spring: main: banner-mode: "off"properties文件：
spring.main.banner-mode=off在主啟動(dòng)類中添加一個(gè)打印方法，利用ANSI轉(zhuǎn)義碼輸出彩色字符：
public class AbsWebApplication { private static final String RESET = "\u001B[0m"; private static final String CYAN = "\u001B[36m"; private static final String BLUE = "\u001B[34m"; private static final String PURPLE = "\u001B[35m"; private static final String WHITE = "\u001B[37m"; public static void main(String[] args) { SpringApplication.run(AbsWebApplication.class, args); printBanner(); } private static void printBanner() { System.out.println(); System.out.println(CYAN + "╔════════════════════════════════════════════╗" + RESET); System.out.println(CYAN + "║" + BLUE + " █████╗ ██████╗ ███████╗ ██████╗ ██╗ ██╗ " + CYAN + "║" + RESET); System.out.println(CYAN + "║" + BLUE + " ██╔══██╗██╔══██╗██╔════╝██╔═══██╗██║ ██╔╝ " + CYAN + "║" + RESET); System.out.println(CYAN + "║" + BLUE + " ███████║██████╔╝█████╗ ██║ ██║█████╔╝ " + CYAN + "║" + RESET); System.out.println(CYAN + "║" + BLUE + " ██╔══██║██╔═══╝ ██╔══╝ ██║ ██║██╔═██╗ " + CYAN + "║" + RESET); System.out.println(CYAN + "║" + BLUE + " ██║ ██║██║ ███████╗╚██████╔╝██║ ██╗ " + CYAN + "║" + RESET); System.out.println(CYAN + "║" + BLUE + " ╚═╝ ╚═╝╚═╝ ╚══════╝ ╚═════╝ ╚═╝ ╚═╝ " + CYAN + "║" + RESET); System.out.println(CYAN + "║ ║" + RESET); System.out.println(CYAN + "║ " + WHITE + ">>> AbsWeb Application 啟動(dòng)成功 <<<" + CYAN + " ║" + RESET); System.out.println(CYAN + "║ " + PURPLE + "版本: v2.6.13 時(shí)間: " + WHITE + java.time.LocalTime.now() + CYAN + " ║" + RESET); System.out.println(CYAN + "╚════════════════════════════════════════════╝" + RESET); System.out.println(); } }輸出結(jié)果如下：
下面多提供幾個(gè)圖案：
public class AbsWebApplication { private static final String RESET = "\u001B[0m"; private static final String CYAN = "\u001B[36m"; private static final String MAGENTA = "\u001B[35m"; private static final String BLUE = "\u001B[34m"; private static final String YELLOW = "\u001B[33m"; public static void main(String[] args) { SpringApplication.run(AbsWebApplication.class, args); printBanner(); } private static void printBanner() { System.out.println(); System.out.println(MAGENTA + "╔══════════════════════════════════════════════════╗" + RESET); System.out.println(MAGENTA + "║ ║" + RESET); System.out.println(MAGENTA + "║ " + CYAN + "██████╗ █████╗ ██████╗ ██████╗ ██╗ ██╗ " + MAGENTA + "║" + RESET); System.out.println(MAGENTA + "║ " + CYAN + "██╔══██╗██╔══██╗██╔══██╗██╔═══██╗██║ ██╔╝ " + MAGENTA + "║" + RESET); System.out.println(MAGENTA + "║ " + BLUE + "██████╔╝███████║██████╔╝██║ ██║██║ ██╔╝ " + MAGENTA + "║" + RESET); System.out.println(MAGENTA + "║ " + BLUE + "██╔═══╝ ██╔══██║██╔═══╝ ██║ ██║██║ ╚═╝ " + MAGENTA + "║" + RESET); System.out.println(MAGENTA + "║ " + YELLOW + "██║ ██║ ██║██║ ╚██████╔╝███████╗ " + MAGENTA + "║" + RESET); System.out.println(MAGENTA + "║ " + YELLOW + "╚═╝ ╚═╝ ╚═╝╚═╝ ╚═════╝ ╚══════╝ " + MAGENTA + "║" + RESET); System.out.println(MAGENTA + "║ ║" + RESET); System.out.println(MAGENTA + "║ " + CYAN + ">>> AbsWeb Application 啟動(dòng)成功 <<< " + MAGENTA + "║" + RESET); System.out.println(MAGENTA + "║ " + CYAN + "版本: v2.6.13 時(shí)間: " + java.time.LocalTime.now() + " " + MAGENTA + "║" + RESET); System.out.println(MAGENTA + "║ ║" + RESET); System.out.println(MAGENTA + "╚══════════════════════════════════════════════════╝" + RESET); System.out.println(); } } public class AbsWebApplication { private static final String RESET = "\u001B[0m"; private static final String RED = "\u001B[31m"; private static final String GREEN = "\u001B[32m"; private static final String BLUE = "\u001B[34m"; private static final String PURPLE = "\u001B[35m"; private static final String YELLOW = "\u001B[33m"; public static void main(String[] args) { SpringApplication.run(AbsWebApplication.class, args); printBanner(); } private static void printBanner() { System.out.println(); System.out.println(PURPLE + "╔══════════════════════════╗" + RESET); System.out.println(PURPLE + "║ " + RED + "▂▃▅▇█ AbsWeb啟動(dòng)成功 █▇▅▃▂" + PURPLE + " ║" + RESET); System.out.println(PURPLE + "║ " + GREEN + "Version: v2.6.13" + " " + PURPLE + "║" + RESET); System.out.println(PURPLE + "║ " + BLUE + "Time: " + java.time.LocalTime.now() + " " + PURPLE + "║" + RESET); System.out.println(PURPLE + "╚══════════════════════════╝" + RESET); System.out.println(); } }自己也可以讓AI去生成。
實(shí)現(xiàn)啟動(dòng)成功后的彩色提示
public class AbsWebApplication { public static void main(String[] args) { SpringApplication.run(AbsWebApplication.class, args); printStartupMessage(); } private static void printStartupMessage() { String reset = "\u001B[0m"; String red = "\u001B[31m"; String yellow = "\u001B[33m"; String green = "\u001B[32m"; String cyan = "\u001B[36m"; String magenta = "\u001B[35m"; String blue = "\u001B[34m"; System.out.println(cyan + " (\\_/) " + reset); System.out.println(cyan + " ( ?_?) " + reset + red + " AbsWebApplication 啟動(dòng)成功!" + reset); System.out.println(cyan + " / > " + reset + yellow + " 祝你今天工作順利，項(xiàng)目無(wú)BUG~" + reset); System.out.println(); System.out.println(magenta + " ┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓" + reset); System.out.println(magenta + " ┃ 歡迎使用 AbsWeb！ ┃" + reset); System.out.println(magenta + " ┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛" + reset); } }啟動(dòng)后示例：
下面提供幾個(gè)示例：
放進(jìn)方法進(jìn)行替換就行了。
