Question

我正在尝试逐个阅读每个日志条目。所以这是日志文件的一部分：

at java.net.Socket.<init>(Socket.java:434)
    at java.net.Socket.<init>(Socket.java:211)
    at sun.rmi.transport.proxy.RMIDirectSocketFactory.createSocket(RMIDirectSocketFactory.java:40)
    at sun.rmi.transport.proxy.RMIMasterSocketFactory.createSocket(RMIMasterSocketFactory.java:148)
    at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:613)
    ... 31 more
26.03.2018 14:43:57,113| INFO http-nio-8080-exec-10 configService==nullLooking up configuration service on rmi://localhost:1199/ConfigService |com.ase.common.utils.ConfigurationServiceUtils
26.03.2018 14:43:57,113| WARN http-nio-8080-exec-10 Could not connect to services. |com.ase.common.utils.ConfigurationServiceUtils
java.rmi.ConnectException: Connection refused to host: localhost; nested exception is: 
    java.net.ConnectException: Connection refused
    at sun.rmi.transport.tcp.TCPEndpoint.newSocket(TCPEndpoint.java:619)
    at sun.rmi.transport.tcp.TCPChannel.createConnection(TCPChannel.java:216)
    at sun.rmi.transport.tcp.TCPChannel.newConnection(TCPChannel.java:202)
    at sun.rmi.server.UnicastRef.newCall(UnicastRef.java:342)
    at sun.rmi.registry.RegistryImpl_Stub.lookup(Unknown Source)

这是日志模式

ConversionPattern =％d {dd.MM.yyyy HH：mm：ss，SSS} | ％p％t％m |％c％n

我需要从每个条目中获取所有详细信息，例如日期，优先级值，线程，消息和类。这就是我到目前为止所做的。

(.*?)\| [A-Z]+ (.*?) (.*?) \|(.*)[\S\s]

它匹配所有条目但没有堆栈跟踪。我是如何改进我的正则表达式以获得堆栈跟踪的呢？

所以我需要这样：

Match1 : `26.03.2018 14:43:57,113| INFO http-nio-8080-exec-10 configService==nullLooking up configuration service on rmi://localhost:1199/ConfigService |com.ase.common.utils.ConfigurationServiceUtils`

您应该在正则表达式中使用更具体的捕获组，我将指出：

^(\d+\.\d+\.\d{4}[^|]+)\|\s+(\S+)\s+(\S+)\s+([^|]+)\|(\S+)\s+((?:(?!^\d+\.)[^|])*)

故障：

^(\d+\.\d+\.\d{4}[^|]+)\|匹配以日期开头的行（Captuing Group＃1）
\s+(\S+)匹配空格并捕获非空白字符（CG＃2）
\s+(\S+)相同（CG＃3）
\s+([^|]+)\|匹配空格和|（CG＃3）
(\S+)\s+匹配并捕获非空白字符，后跟空格（CG＃4）
((?:(?!^\d+\.)[^|])*)钢化模式，检查它是否在应该是下一个匹配开始的行的开头。如果不匹配下一个直接字符（CG＃5，可选组）
