尝试以下枚举:

enum Color {
    //Color end string, color reset
    RESET("\033[0m"),

    // Regular Colors. Normal color, no bold, background color etc.
    BLACK("\033[0;30m"),    // BLACK
    RED("\033[0;31m"),      // RED
    GREEN("\033[0;32m"),    // GREEN
    YELLOW("\033[0;33m"),   // YELLOW
    BLUE("\033[0;34m"),     // BLUE
    MAGENTA("\033[0;35m"),  // MAGENTA
    CYAN("\033[0;36m"),     // CYAN
    WHITE("\033[0;37m"),    // WHITE

    // Bold
    BLACK_BOLD("\033[1;30m"),   // BLACK
    RED_BOLD("\033[1;31m"),     // RED
    GREEN_BOLD("\033[1;32m"),   // GREEN
    YELLOW_BOLD("\033[1;33m"),  // YELLOW
    BLUE_BOLD("\033[1;34m"),    // BLUE
    MAGENTA_BOLD("\033[1;35m"), // MAGENTA
    CYAN_BOLD("\033[1;36m"),    // CYAN
    WHITE_BOLD("\033[1;37m"),   // WHITE

    // Underline
    BLACK_UNDERLINED("\033[4;30m"),     // BLACK
    RED_UNDERLINED("\033[4;31m"),       // RED
    GREEN_UNDERLINED("\033[4;32m"),     // GREEN
    YELLOW_UNDERLINED("\033[4;33m"),    // YELLOW
    BLUE_UNDERLINED("\033[4;34m"),      // BLUE
    MAGENTA_UNDERLINED("\033[4;35m"),   // MAGENTA
    CYAN_UNDERLINED("\033[4;36m"),      // CYAN
    WHITE_UNDERLINED("\033[4;37m"),     // WHITE

    // Background
    BLACK_BACKGROUND("\033[40m"),   // BLACK
    RED_BACKGROUND("\033[41m"),     // RED
    GREEN_BACKGROUND("\033[42m"),   // GREEN
    YELLOW_BACKGROUND("\033[43m"),  // YELLOW
    BLUE_BACKGROUND("\033[44m"),    // BLUE
    MAGENTA_BACKGROUND("\033[45m"), // MAGENTA
    CYAN_BACKGROUND("\033[46m"),    // CYAN
    WHITE_BACKGROUND("\033[47m"),   // WHITE

    // High Intensity
    BLACK_BRIGHT("\033[0;90m"),     // BLACK
    RED_BRIGHT("\033[0;91m"),       // RED
    GREEN_BRIGHT("\033[0;92m"),     // GREEN
    YELLOW_BRIGHT("\033[0;93m"),    // YELLOW
    BLUE_BRIGHT("\033[0;94m"),      // BLUE
    MAGENTA_BRIGHT("\033[0;95m"),   // MAGENTA
    CYAN_BRIGHT("\033[0;96m"),      // CYAN
    WHITE_BRIGHT("\033[0;97m"),     // WHITE

    // Bold High Intensity
    BLACK_BOLD_BRIGHT("\033[1;90m"),    // BLACK
    RED_BOLD_BRIGHT("\033[1;91m"),      // RED
    GREEN_BOLD_BRIGHT("\033[1;92m"),    // GREEN
    YELLOW_BOLD_BRIGHT("\033[1;93m"),   // YELLOW
    BLUE_BOLD_BRIGHT("\033[1;94m"),     // BLUE
    MAGENTA_BOLD_BRIGHT("\033[1;95m"),  // MAGENTA
    CYAN_BOLD_BRIGHT("\033[1;96m"),     // CYAN
    WHITE_BOLD_BRIGHT("\033[1;97m"),    // WHITE

    // High Intensity backgrounds
    BLACK_BACKGROUND_BRIGHT("\033[0;100m"),     // BLACK
    RED_BACKGROUND_BRIGHT("\033[0;101m"),       // RED
    GREEN_BACKGROUND_BRIGHT("\033[0;102m"),     // GREEN
    YELLOW_BACKGROUND_BRIGHT("\033[0;103m"),    // YELLOW
    BLUE_BACKGROUND_BRIGHT("\033[0;104m"),      // BLUE
    MAGENTA_BACKGROUND_BRIGHT("\033[0;105m"),   // MAGENTA
    CYAN_BACKGROUND_BRIGHT("\033[0;106m"),      // CYAN
    WHITE_BACKGROUND_BRIGHT("\033[0;107m");     // WHITE

    private final String code;

    Color(String code) {
        this.code = code;
    }

    @Override
    public String toString() {
        return code;
    }
}

现在我们来举个小例子:

class RunApp {
    public static void main(String[] args) {

        System.out.print(Color.BLACK_BOLD);
        System.out.println("Black_Bold");
        System.out.print(Color.RESET);

        System.out.print(Color.YELLOW);
        System.out.print(Color.BLUE_BACKGROUND);
        System.out.println("YELLOW & BLUE");
        System.out.print(Color.RESET);

        System.out.print(Color.YELLOW);
        System.out.println("YELLOW");
        System.out.print(Color.RESET);
    }
}

使用颜色功能打印带有颜色的文本

代码:

enum Color {

    RED("\033[0;31m"),      // RED
    GREEN("\033[0;32m"),    // GREEN
    YELLOW("\033[0;33m"),   // YELLOW
    BLUE("\033[0;34m"),     // BLUE
    MAGENTA("\033[0;35m"),  // MAGENTA
    CYAN("\033[0;36m"),     // CYAN

    private final String code

    Color(String code) {
        this.code = code;
    }

    @Override
    String toString() {
        return code
    }
}

def color = { color, txt ->
    def RESET_COLOR = "\033[0m"
    return "${color}${txt}${RESET_COLOR}"
}

用法:

test {
    println color(Color.CYAN, 'testing')
}

您可以使用ANSI转义序列来实现这一点。实际上，我已经在Java中为任何想要简单解决这个问题的人组合了这个类。它允许的不仅仅是颜色代码。

https://gist.github.com/nathan-fiscaletti/9dc252d30b51df7d710a

特性

完整的源代码文档 4位颜色支持(16种颜色) 8位颜色支持(255种颜色) 24位颜色支持(1670万种颜色) 支持十六进制和8位RGB值 支持通用格式 隐藏文本，反转颜色，闪烁，下划线，删除，暗淡，粗体，斜体 能够从包含ANSI转义序列的字符串中剥离ANSI。

示例使用

System.out.println(

   new AnsiStringBuilder()
       // All formatting functions support at least three different
       // overloads, each intended for a different use case.

       // Use case 1: Manual Reset
       .italic()
       .append("This is italicized and reset manually.")
       // You can optionaly supply an additional append string
       // to any of the reset functions that will be appended
       // after the formating reset has been applied.
       .resetItalic(System.lineSeparator())

       // Use case 2: Automatic Reset
       .dim("This is dimmed and reset automatically.")
       .append(System.lineSeparator())

       // Use case 3: Function Consumer
       .underline(
           sb -> {
               // The string builder passed to this function consumer
               // will automatically wrap all content appended to it
               // with the underline formatting.
               sb.color24(
                   "#00ff00",
                   "This is both underlined and green"
               );
           }
       )
       .append(System.lineSeparator())

);

如果你使用Kotlin(它与Java无缝工作)，你可以创建这样一个枚举:

enum class AnsiColor(private val colorNumber: Byte) {
    BLACK(0), RED(1), GREEN(2), YELLOW(3), BLUE(4), MAGENTA(5), CYAN(6), WHITE(7);

    companion object {
        private const val prefix = "\u001B"
        const val RESET = "$prefix[0m"
        private val isCompatible = "win" !in System.getProperty("os.name").toLowerCase()
    }

    val regular get() = if (isCompatible) "$prefix[0;3${colorNumber}m" else ""
    val bold get() = if (isCompatible) "$prefix[1;3${colorNumber}m" else ""
    val underline get() = if (isCompatible) "$prefix[4;3${colorNumber}m" else ""
    val background get() = if (isCompatible) "$prefix[4${colorNumber}m" else ""
    val highIntensity get() = if (isCompatible) "$prefix[0;9${colorNumber}m" else ""
    val boldHighIntensity get() = if (isCompatible) "$prefix[1;9${colorNumber}m" else ""
    val backgroundHighIntensity get() = if (isCompatible) "$prefix[0;10${colorNumber}m" else ""
}

然后像这样使用is:(下面的代码展示了所有颜色的不同样式)

val sampleText = "This is a sample text"
enumValues<AnsiColor>().forEach { ansiColor ->
    println("${ansiColor.regular}$sampleText${AnsiColor.RESET}")
    println("${ansiColor.bold}$sampleText${AnsiColor.RESET}")
    println("${ansiColor.underline}$sampleText${AnsiColor.RESET}")
    println("${ansiColor.background}$sampleText${AnsiColor.RESET}")
    println("${ansiColor.highIntensity}$sampleText${AnsiColor.RESET}")
    println("${ansiColor.boldHighIntensity}$sampleText${AnsiColor.RESET}")
    println("${ansiColor.backgroundHighIntensity}$sampleText${AnsiColor.RESET}")
}

如果运行在不支持这些ANSI代码的Windows上，isCompatible检查通过将代码替换为空字符串来避免问题。

一种相当可移植的方法是使用原始转义序列。参见http://en.wikipedia.org/wiki/ANSI_escape_code

Java不“处理代码”，这是真的，但是Java输出你让它输出的东西。Windows控制台将ESC (chr(27))视为另一个符号(←)，这不是Java的错。

您可以使用JAnsi依赖项在Linux和Windows中更改颜色。 它以正确的方式打印UTF-8字符。 https://github.com/fusesource/jansi
