logback:控制异常堆栈跟踪的格式

Question

我在Scala/Play 2.2.0应用程序上使用Logback 1.0.13.现有配置如下:

  <appender name="FILE" class="ch.qos.logback.core.FileAppender">
    <file>${application.home}/logs/application.log</file>
    <encoder>
     <pattern>%date [%level][%logger{1}][%thread{1}] %message%xException%n</pattern>
    </encoder>
  </appender>

我正在寻找是否有办法配置它,以便异常追溯线有一个自定义的分隔符.代替

play.api.Configuration$$anon$1: Configuration error[Cannot connect to database [default]]
at play.api.Configuration$.play$api$Configuration$$configError(Configuration.scala:92) ~[play_2.10-2.2.0.jar:2.2.0]
at play.api.Configuration.reportError(Configuration.scala:570) ~[play_2.10-2.2.0.jar:2.2.0]
at play.api.db.BoneCPPlugin$$anonfun$onStart$1.apply(DB.scala:252) ~[play-jdbc_2.10-2.2.0.jar:2.2.0]

我想在每行前面放一些字符,如下所示:

play.api.Configuration$$anon$1: Configuration error[Cannot connect to database [default]]
>>> at play.api.Configuration$.play$api$Configuration$$configError(Configuration.scala:92) ~[play_2.10-2.2.0.jar:2.2.0]
>>> at play.api.Configuration.reportError(Configuration.scala:570) ~[play_2.10-2.2.0.jar:2.2.0]
>>> at play.api.db.BoneCPPlugin$$anonfun$onStart$1.apply(DB.scala:252) ~[play-jdbc_2.10-2.2.0.jar:2.2.0]

Answer 1

我想出了这样的作品:

       <pattern>%date [%level][%logger{1}][%thread{1}] 
         %message%replace(%xException){"\n", "\\n"}%nopex%n</pattern>  

%replace机制适用于堆栈跟踪文本.你还需要%nopex来防止原始堆栈跟踪再次出现; 否则,"帮助"注销会忽略跟踪并将其包含在内.
