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。

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

    MAGENTA("\033[0;35m"),  // MAGENTA
    CYAN("\033[0;36m"),     // CYAN
    WHITE("\033[0;37m"),    // WHITE

    // Bold

    // 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

    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);
    }
}

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

    public static final String BLUE = "\033[0;34m";    // BLUE
    public static final String PURPLE = "\033[0;35m";  // PURPLE
    public static final String CYAN = "\033[0;36m";    // CYAN
    public static final String WHITE = "\033[0;37m";   // WHITE
