正则表达式转义所有特殊符号

特殊符号包括

 $ ( ) * + . [ ] ? ^ { } | -

实现代码(java)

public class RegexUtils {
    private static final String[] SPECIAL_SYMBOLS =
            new String[]{"\", "$", "(", ")", "*", "+", ".", "[", "]", "?", "^", "{", "}", "|", "-"};

    /**
     * 转义目标正则表达式中的所有特殊字符
     * @param regex
     * @return
     */
    public static String escapeSpecialSymbols(String regex) {
        for (String specSymbol : SPECIAL_SYMBOLS) {
            String escapeSymbol = "\" + specSymbol;
            regex = regex.replace(specSymbol, escapeSymbol);
        }
        return regex;
    }
}
