一、自定义 Spring Boot 启动横幅 banner.txt

1、什么是 banner.txt？

当你启动 Spring Boot 应用时，控制台会打印出一个默认的 Spring Boot Banner（比如启动LOGO）。这个内容来自 resources 目录下的 banner.txt 文件。你可以通过这个文件自定义你想展示的 ASCII 图案、版本号、提示文字等。

2、创建或修改 banner.txt

2.1、文件位置：

在你的 Spring Boot 项目中，进入 src/main/resources 目录下，新建或编辑：

src/main/resources/banner.txt

2.2. 内容示例（纯色风格 + 启动信息）：

===========================================
==         AbsWeb 启动成功！ 🚀         ==
==         端口：${server.port}               ==
==         环境：${spring.profiles.active}       ==
==         时间：${date}              ==
===========================================

你可以使用 Spring Boot 提供的一些占位符变量：

占位符	描述
${application.version}	项目的 MANIFEST.MF 版本
${application.formatted-version}	格式化版本号
${spring-boot.version}	Spring Boot 版本
${server.port}	当前端口号
${spring.profiles.active}	当前激活的配置环境
${date}	启动时间
${AnsiColor.NAME}	控制台颜色（如 GREEN、RED）

3、加点颜色和风格（可选）

Spring Boot 支持 ANSI 颜色，在支持的终端中会显示彩色效果：

${AnsiColor.BRIGHT_CYAN}
===========================================
==         AbsWeb 启动成功！ 🚀         ==
==         端口：${server.port}               ==
==         环境：${spring.profiles.active}       ==
==         时间：${date}              ==
===========================================
${AnsiColor.DEFAULT}

4、启动测试

启动项目时，你会看到类似输出：

===========================================
==         AbsWeb 启动成功！ 🚀         ==
==         端口：8082                     ==
==         环境：test                     ==
==         时间：2025-06-13 16:52:10      ==
===========================================

二、进阶方式：关闭默认 Banner，自定义 Java 启动内容

1、禁用 Spring Boot 的默认 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

2、自定义启动打印代码

在主启动类中添加一个打印方法，利用ANSI转义码输出彩色字符：

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 启动成功 <<<" + CYAN + "           ║" + RESET);
        System.out.println(CYAN + "║ " + PURPLE + "版本: v2.6.13  时间: " + WHITE + java.time.LocalTime.now() + CYAN + "        ║" + RESET);
        System.out.println(CYAN + "╚════════════════════════════════════════════╝" + RESET);
        System.out.println();
    }
}

输出结果如下：

下面多提供几个图案：

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 启动成功 <<<               " + MAGENTA + "║" + RESET);
        System.out.println(MAGENTA + "║   " + CYAN + "版本: v2.6.13    时间: " + 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启动成功 █▇▅▃▂" + 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();
    }
}

自己也可以让AI去生成。

三、实现启动成功后的彩色提示

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 启动成功!" + reset);
        System.out.println(cyan + "  / >🍪  " + reset + yellow + "  祝你今天工作顺利，项目无BUG~" + reset);
        System.out.println();
        System.out.println(magenta + "  ┏━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┓" + reset);
        System.out.println(magenta + "  ┃      🎉 欢迎使用 AbsWeb！🎉     ┃" + reset);
        System.out.println(magenta + "  ┗━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━┛" + reset);
    }
}

启动后示例：

下面提供几个示例：

放进方法进行替换就行了。

final String PURPLE = "\u001B[35m";
final String RED = "\u001B[31m";
final String RESET = "\u001B[0m";

System.out.println(PURPLE + "   .----.  .----. " + RESET);
System.out.println(PURPLE + "  /      \\/      \\" + RESET);
System.out.println(RED + " |  (•)   (•)  | " + RESET);
System.out.println(PURPLE + " |     <       | " + RESET);
System.out.println(PURPLE + "  \\   --'    /  " + RESET);
System.out.println(PURPLE + "   `--------'    " + RESET);
System.out.println(RED + "    AbsWeb 已启动!" + RESET);
public static void printTechWave() {
    final String RESET = "\u001B[0m";
    final String BLUE = "\u001B[34m";
    final String CYAN = "\u001B[36m";
    final String PURPLE = "\u001B[35m";
    final String WHITE = "\u001B[37m";

    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(PURPLE + "║    🚀 AbsWeb Application 启动成功！🚀       ║" + RESET);
    System.out.println(PURPLE + "║   Version: v2.6.13    " + WHITE + "启动时间: " + java.time.LocalTime.now() + "   " + PURPLE + " ║" + RESET);
    System.out.println(CYAN + "╚════════════════════════════════════════════╝" + RESET);
}
