1. 正则表达式简介

正则表达式是用于描述文本/字符串的一组规则，可以用来处理文本或者提取信息。
学习正则的感受：

使用、强大、程序员必备通识，增强了文本编辑器的搜索功能，用很少代码完成复杂文本的提取
难学、难懂、反人类，调试半天写了个很强的正则，下周再看可能又懵了
学习和阅读正则时，耐心分解，一点点分析，利用好在线正则工具和文本编辑器的正则搜索

即使不是程序员，可能也知道电脑中有个通配符 * 的概念，可以在搜索文件时匹配任意文件名，比如 *.txt ，而正则表达式就是一组更强大的匹配规则。

Java 中的转义字符

有些字符不可见，无法方便的在屏幕上或者在字符串中表示，因此需要转义，根据转换格则，来代替真正想表达的那个含义，就像象形文字对于物理事物的表示，所以这也是一种预先的约定。

/ 斜杠（slash）
\ 反斜杠（backslash）

使用 \ 对不可见字符进行转义表示（不然人类眼睛无法观察到），使用 \\ 用来转义表示 \ 自身。
System.lineSeparator() 可以返回当前系统的换行符，Windows 系统中是 \r\n ，Unix 系统中是 \n 。

\n 在8进制码表中是 012 nl(new line)，表示换行符，耳熟能详，都知道 \n 是换行符的转义表示法，但如果不知道该怎么表示的话，直接 \12 也可以表示换行符，而这时候的数字是依照8进制码表。

看下面的例子中 \n 和 \12 是一回事，而换行符对应的十进制码表是10。
当然 $ 美元 dollar 符号是可见字符，完全可以直接用 $ 自身来表示，不需要转义，但如果乐意的话，使用码表绕晕自己也是合法的：

下面分别是8进制、16进制和10进制的 ASCII 码表（使用 man ascii 可以快速查看）：
16进制中，20 sp 及之前的都是不可见字符，需要用字符表达时，需要转义。

2. 正则表达式的必备知识

正则表达式是个通用的规范，具体的编程语言中的实现方式可能略有不同。

元字符
重复
选择
反义

对比刚才针对 ASCII 码表中不可见字符进行转义时，正则表达式中的转义概念更广一些，因为针对正则中的语法“关键字”字符（元字符、重复、选择、反义等），当需要引用这些字符本身的含义时，也需要进行转义。因为会和正则“关键字”产生歧义，否则也可以不转义。

常用的元字符

. 单个任意字符（默认不包含换行符，见下面的解释和底部的参考链接）
\w 字母或数字或下划线，等价于 [^A-Za-z0-9_] （是否包括汉字视应用环境而定）
\s 单个空白字符（如\n\r\t）
\d 单个数字
\b 单词的开始或结束（很少用，以后再研究）
^ 开始位置
$ 结束位置

在 Java 中 . 能否匹配换行符，可以通过正则开头添加 (?s) 来指示。
s 是正则表达式的模式修饰符之一。表示更改 . 的含义，使它与每一个字符匹配，包括换行符 \n 。

重复

* 0 次或多次（任意次数）
+ 1 次或多次（至少 1 次）
? 0 次或 1 次（最多 1 次）
{n} n 次
{n,} >= n 次（至少 n 次）
{n,m} n 到 m 次

选择

从一组中选择1个，例如：

[aeiou] 单个的 a/e/i/o/u 个字符之一
[0-9] 单个数字
[A-Z] 单个大写字母
[A-Z0-9_] 单个大写字母或者数字或者下划线
Hi|hi 等价于 [Hh]i Hi 或者 hi

反义

[^aeiou] 单个的除 a/e/i/o/u 之外的字符
[^A] 单个非 A 的字符
\W 单个非 \w（字母/数字/下划线/汉字）字符
\S 单个非 \s（空白）字符
\D 单个非 \d（数字）字符
\B 非开头/结束位置

正则例子

^\d{5,12}$ 5到12位的数字
^(0|[1-9][0-9]*)$ 0或者非零开头的数字
^(-?\d+)(.\d+)?$ 可能包含小数的数字
\d{3}-\d{8}|\d{4}-\d{7,8} 国内的电话号码
^\d{4}-\d{1,2}-\d{1,2} yyyy-MM-dd ⽇期格式
\n\s*\r 空白⾏

Java 中的正则表达式

String split、replaceAll/replaceFirst、matches
尽量少用或者少编译（存为静态常量，避免每次都要重新编译），因为编译和执行的效率低
Java 中的正则表达式是⽐较昂贵的
正则表达式需要解析，代码⾮常昂贵，匹配过程非常昂贵

分组与捕获

想要将所有符合正则表达式的⽂本抓出来处理
使⽤圆括号来指定一个被捕获的分组
分组的编号从 1 开始（分组编号 0 代表整个匹配到的字符序列）
分组的编号计算只看左括号 (
(?:) 不捕获和分配编号，括号只⽤于分组或标记优先级（如 (?:balabala) ，不然会被当做一个捕获组）

在 Java 中处理捕获

Pattern
- matcher()
Matcher
- find()
- group(n)

3. 实战练习

判断一个字符串是不是合法的固定电话号码

import java.util.regex.Pattern;
public class PhoneNumberMatcher {
    // 请编写一个函数，判断一个字符串是不是合法的固定电话号码
    // 合法的固定电话号码为：区号-号码
    // 其中区号以0开头，三位或者四位
    // 号码以非零开头，七位或者八位
    // 三位区号后面只能跟八位电话号码
    // 合法的电话号码示例：
    // 021-12345678
    // 0571-12345678
    // 0373-1234567
    // 不合法的电话号码示例：
    // 02134-1234 位数不对
    // 123-45678901 区号必须以0开头
    // 021-1234567 三位区号后面只能跟八位电话号码
    public static final Pattern PHONE_REGEXP = Pattern.compile("0\\d{2}-[1-9]\\d{7}|0\\d{3}-[1-9]\\d{6,7}");
    public static boolean isPhoneNumber(String str) {
        return PHONE_REGEXP.matcher(str).find();
    }
    public static void main(String[] args) {
        boolean isPhoneNumber = isPhoneNumber("021-02345678");
        System.out.println(isPhoneNumber);
    }
}

传入日志字符串，将每行开头的时间戳删除

public class LogProcessor {
    // 传入日志字符串，将每行开头的时间戳删除
    // 返回删除时间戳后的字符串
    // 例如，输入字符串：
    //
    // [2019-08-01 21:24:41] bt3102 (11m:21s)
    // [2019-08-01 21:24:42] TeamCity server version is 2019.1.1 (build 66192)
    // [2019-08-01 21:24:43] Collecting changes in 2 VCS roots (22s)
    //
    // 返回结果：
    //
    // bt3102 (11m:21s)
    // TeamCity server version is 2019.1.1 (build 66192)
    // Collecting changes in 2 VCS roots (22s)

    // 使用正则修饰符 (?m)，m 代表把目标字符串按照多行来处理，因此可以使用 ^ 分别匹配若干个开头
    public static final String TIMESTAMP_REGEX = "(?m)^\\[\\d{4}(-\\d{2}){2}\\s\\d{2}(:\\d{2}){2}]";

    public static String process(String log) {
        return log.replaceAll(TIMESTAMP_REGEX, "");
    }

    public static void main(String[] args) {
        String str =
                "[2019-08-01 21:24:41] bt3102 (11m:21s)\n"
                        + "[2019-08-01 21:24:42] TeamCity server [2019-08-01 21:24:42] version is 2019.1.1 (build 66192)\n"
                        + "[2019-08-01 21:24:43] Collecting changes in 2 VCS roots (22s)\n";

        System.out.println(process(str));
    }
}
