const regex = /^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[^a-zA-Z\d<>"'\\|])(?!.*[<>"'\\|])/; console.log(regex.test("AaBb123!@#")); // output: true
public static void main(String[] args) { Pattern compile = Pattern.compile("^(?=.*[a-z])(?=.*[A-Z])(?=.*\\d)(?=.*[^a-zA-Z\\d<>\"'\\\\|])(?!.*[<>\"'\\\\|])"); Matcher matcher = compile.matcher("AaBb123!@#"); System.out.println(matcher.matches()); // output: false }
丢给 AI 也看不出什么问题,AI 的结论是两段代码输出都应该一样为 true

![]() | 3 nagisaushio 360 天前 ![]() java 的 matcher.matches 是尝试匹配整个字符串吧?你在 java 的正则后面加个 .* 就对了 |

7 NeroKamin OP @nagisaushio #3 加上确实好使了。也就是说 js regexp.test 和 java matcher.matches 的意义是不一样的吗? |
