Your problem is that the backslash has special meaning both in Java strings and in regexes. So you need four slashes in the Java source code, passing two to the regex parser to get one literal one in the regex:
您的问题是反斜杠在 Java 字符串和正则表达式中都有特殊含义。因此，您需要在 Java 源代码中使用四个斜杠，将两个斜杠传递给正则表达式解析器以在正则表达式中获得一个字面值：
return userWithDomain.replaceAll("^.*\\", "");
