我在应用程序中有这些日志,我想解析它们。我创建了一个正则表达式,但是它不能按预期运行,因为它无法解析日志中的完整堆栈跟踪。这是我当前的表情:
^(?<time>[0-9]+-[0-9]+-[0-9]+\s+[0-9]+:[0-9]+:[0-9]+.[0-9]+)[\s]*(?<level>[^\s]+) (?<pid>[\d]+) --- \[(?<thread>.*)\] (?<class>[^\s]+)[\s]*:[\s]*(?<message>.*)
这些是我从应用程序中获得的日志:

您可以看到here,该正则表达式与完整堆栈跟踪不匹配。任何帮助,我们将不胜感激。
答案 0 :(得分:3)
您可以使用
^(?<time>\d+(?:-\d+){2}\s+\d+(?::\d+){2}\.\d+)\s*(?<level>\S+) (?<pid>\d+) --- \[(?<thread>[\s\S]*?)\] (?<class>\S+)\s*:\s*(?<message>[\s\S]*?)(?=\g<time>|\Z)
请参见regex demo。
要点是:
.
被[\s\S]
替换(或者,您可以保留.
,但是在模式的开头使用(?m)
来使.
与行匹配打破字符,这是m
标志的仅Ruby行为).*
太贪婪,请使用惰性量词.*?
(?=\g<time>|\Z)
。它检查在当前位置之后是否有时间模式(\g<time>
,这是递归time
组模式的子例程)或字符串结尾(\Z
)。我也将[^\s]
“美化”为\S
,将[\d]
命名为\d
,将[\s]
命名为\s
,并对重复的模式进行分组。您也可以用\s+
替换空格,以确保匹配任意数量的空白字符。
