如何在控制台使用System.out.println打印颜色?

我如何在控制台打印颜色?当处理器发送数据时，我想用不同的颜色显示数据，当处理器接收数据时，我想用不同的颜色显示数据。

当前回答

为控制台文本上色的最好方法是使用ANSI转义码。除了文本颜色，ANSI转义码还允许背景色、装饰色等。

Unix

如果你使用springboot，文本着色有一个特定的enum: org.springframework.boot.ansi.AnsiColor

Jansi库更高级一点(可以使用所有的ANSI转义代码函数)，提供了一个API，并支持使用JNA的Windows。

否则，您可以手动定义自己的颜色，如其他响应所示。

Windows 10

Windows 10(自build 10.0.10586 - 2015年11月)支持ANSI转义码(MSDN文档)，但默认情况下不启用。启用它:

对于SetConsoleMode API，使用ENABLE_VIRTUAL_TERMINAL_PROCESSING (0x0400)标志。Jansi使用这个选项。如果没有使用SetConsoleMode API，可以通过创建一个dword来更改全局注册表键HKEY_CURRENT_USER\Console\VirtualTerminalLevel，并将其设置为0或1用于ANSI处理: “VirtualTerminalLevel”= dword: 00000001

Windows 10之前

Windows控制台不支持ANSI颜色。但也可以使用控制台。

下面是带有公共静态字段的Java类中的颜色列表

使用

System.out.println(ConsoleColors.RED + "RED COLORED" +
ConsoleColors.RESET + " NORMAL");

请注意不要忘记在打印后使用RESET，因为如果它没有被清除，效果将仍然存在

public class ConsoleColors {
    // Reset
    public static final String RESET = "\033[0m";  // Text Reset

    // Regular Colors
    public static final String BLACK = "\033[0;30m";   // BLACK

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

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

    MAGENTA_UNDERLINED("\033[4;35m"),   // MAGENTA
    CYAN_UNDERLINED("\033[4;36m"),      // CYAN
    WHITE_UNDERLINED("\033[4;37m"),     // WHITE

    // Background
    BLACK_BACKGROUND("\033[40m"),   // BLACK

    // 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);
    }
}

这个kotlin代码对我有用


import java.io.PrintStream

sealed class BackgroundColor(val value: Int) {
    object Default : BackgroundColor(0)

    // normal colors
    object Black : BackgroundColor(40)
    object Red : BackgroundColor(41)
    object Green : BackgroundColor(42)
    object Yellow : BackgroundColor(43)
    object Blue : BackgroundColor(44)
    object Magenta : BackgroundColor(45)
    object Cyan : BackgroundColor(46)
    object White : BackgroundColor(47)

    // colors with high contrast
    object BlackBright : BackgroundColor(100)
    object RedBright : BackgroundColor(101)
    object GreenBright : BackgroundColor(102)
    object YellowBright : BackgroundColor(103)
    object BlueBright : BackgroundColor(104)
    object MagentaBright : BackgroundColor(105)
    object CyanBright : BackgroundColor(106)
    object WhiteBright : BackgroundColor(107)
}

sealed class TextColor(val value: Int) {
    object Default : TextColor(0)

    // normal colors
    object Black : TextColor(30)
    object Red : TextColor(31)
    object Green : TextColor(32)
    object Yellow : TextColor(33)
    object Blue : TextColor(34)
    object Magenta : TextColor(35)
    object Cyan : TextColor(36)
    object White : TextColor(37)

    // colors with high contrast
    object BlackBright : TextColor(90)
    object RedBright : TextColor(91)
    object GreenBright : TextColor(92)
    object YellowBright : TextColor(93)
    object BlueBright : TextColor(94)
    object MagentaBright : TextColor(95)
    object CyanBright : TextColor(96)
    object WhiteBright : TextColor(97)
}

fun styleOutput(
    backgroundColor: BackgroundColor = BackgroundColor.Default,
    textColor: TextColor = TextColor.Default,
    boldText : Boolean = false,
    italicText : Boolean = false,
    underLineText : Boolean = false,
    action : PrintStream.() -> Unit
) {
    val styleFormat = StringBuilder("${27.toChar()}[${backgroundColor.value};${textColor.value}")

   if (boldText)
       styleFormat.append(";1")

    if (italicText)
        styleFormat.append(";3")

    if (underLineText)
        styleFormat.append(";4")

    styleFormat.append("m")

    print(styleFormat)
    System.out.action()
    print("${27.toChar()}[0m")
}

然后使用它

print("text without styling")
styleOutput(backgroundColor = BackgroundColor.Blue, textColor = TextColor.GreenBright, boldText = true) {
    print("text with styling")
}
print("text without styling")
