## 前言 ##

日志在项目中非常常见，一般我们都是打印默认的日志。通过System.out.print(“xxx”) 或者 log.info(“xxx”) 等来打印日志。但有时我们需要打印一些彩色的日志，比如我们调试日志时，想要打印一个日志，然后在控制台定位问题，但如果控制台日志非常多，就需要找好长一段时间，如果日志是彩色的那么就很好定位了。

## 实现 ##

只需要在 打印日志时日志体前后加上特殊字符即可，如下。

@Slf4j
    public class TestController { 
    
        public static void main(String[] args) { 
            System.out.println("我是一条log");
            /* 日志字体颜色 */
            System.out.println(ConsoleColors.GREY+"我是一条log,我有颜色吗"+ConsoleColors.RESET);
            log.info(ConsoleColors.WHITE+"我是一条log,我有颜色吗"+ConsoleColors.RESET);
            /* 日志背景颜色 */
            log.info(ConsoleColors.YELLOW_BACKGROUND+"我是一条log,我有背景吗"+ConsoleColors.RESET);
            /* 日志字体加粗颜色 */
            log.info(ConsoleColors.RED_BOLD+"我是一条特殊log"+ConsoleColors.RESET);
            /* 日志字体加粗颜色 */
            log.info(ConsoleColors.RED_UNDERLINED+"我是一条特殊log"+ConsoleColors.RESET);
        }
    }

具体颜色常量如下。

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