Java堆栈跟踪正则表达式
Java堆栈跟踪正则表达式
提问于 2019-06-14 13:06:55
如果是像这样的堆栈跟踪，我需要匹配Java堆栈跟踪
Exception in thread "main" java.lang.IllegalStateException: A book has a null property
at com.example.myproject.Author.getBookIds(Author.java:38)
at com.example.myproject.Bootstrap.main(Bootstrap.java:14)
Caused by: java.lang.NullPointerException
at com.example.myproject.Book.getId(Book.java:22)
at com.example.myproject.Author.getBookIds(Author.java:36)我可以将它与^[[:space:]]+(at|\.{3})\b|^Caused by:匹配，问题是我需要匹配整个堆栈跟踪，我得到的跟踪如下所示：

一个选项可能是从以日期开始的字符串中匹配。然后重复所有不以日期开头或有at的行。然后确保与at匹配至少1行，然后匹配所有行，直到下一次日期：
^\d{4}-\d{2}-\d{2}.*(?:\n(?!(?:\d{4}-\d{2}-\d{2}|\h+at)).*)*\n\h+at\h+.*(?:\n(?!\d{4}-\d{2}-\d{2}).*)*解释
- 字符串的
^开始 \d{4}-\d{2}-\d{2}.*匹配一个类似日期的模式，后面跟着0+乘以除新行之外的任何字符(?:非捕获群\n(?!(?:\d{4}-\d{2}-\d{2}|\h+at)).*匹配换行符，然后断言右边的不是类似日期的模式或1+水平空格字符后面跟着at。如果是这样，则匹配0+乘以除换行符以外的任何字符。
)*关闭非捕获组并重复0+时间\n\h+at\h+.*匹配以at为起始的一行，该行由1+水平空格字符包围。(?:\n(?!\d{4}-\d{2}-\d{2}).*)*匹配所有未以类似日期模式开头的行
注意在Java中双转义反斜杠：
String regex = "^\\d{4}-\\d{2}-\\d{2}.*(?:\\n(?!(?:\\d{4}-\\d{2}-\\d{2}|\\h+at)).*)*\\n\\h+at\\h+.*(?:\\n(?!\\d{4}-\\d{2}-\\d{2}).*)*";Stack Overflow用户

试试Regex：^(?:Caused by:|\s+(?:at|\.{3})).*$
