Answer 1

간단하게 보면 큰 따옴표를 이스케이프 처리해야합니다. 당신이 백 참조 그룹 (그룹 1) 내부의 큰 따옴표를해야하는 경우

String input = "Key: \"employeeNo\" with value \"ABC12345\" is already used."; 
Pattern p = Pattern.compile("Key: \"employeeNo\" with value \"(ABC\\d+)\" is already used."); 
Matcher m = p.matcher(input); 
if (m.find()) { 
    System.out.println(m.group()); 
    System.out.println(m.group(1)); 
} 

출력

Key: "employeeNo" with value "ABC12345" is already used. 
ABC12345 

, 그냥 그룹 괄호 안에 탈출 따옴표로 묶어야 : (\"ABC\\d+\").
