logback 1.1.3 发布，Java开源日志组件

Logback是由log4j创始人设计的又一个开 源日志组件。logback当前分成三个模块：logback-core,logback- classic和logback-access。logback-core是其它两个模块的基础模块。logback-classic是log4j的一个 改良版本。此外logback-classic完整实现SLF4J API使你可以很方便地更换成其它日志系统如log4j或JDK14 Logging。logback-access访问模块与Servlet容器集成提供通过Http来访问日志的功能。

• Fixed FileAppender's prudent mode so that it properly recovers from IO Errors (LOGBACK-1046)

• Irrelevant or internal stack trace lines can now be omitted. (LOGBACK-540).

• AccessEvent now creates a copy of request attributes when its prepareForDeferredProcessing() method is called.   (LOGBACK-1033)

• All threads opened by ch.qos.logback.core.util.ExecutorServiceUtil#THREAD_FACTORY are now daemons, which fixes an application hang on shutdown when LoggerContext#stop()  is not called (LOGBACK-929).  

• Fixed an issue with RollingFileAppender where the first rollover file could be unintentionally deleted, depending on the specified filename pattern (LOGBACK-894).

• Fixed an issue with TeeHttpServletResponse where the system default encoding would be used instead of the  response encoding when constructing a new writer  (LOGBACK-1023).

• Fixed ConfigurationDelegate.groovy to allow any appender    that implements AppenderAttachable, which supports third-party appenders, such as reactor-logback's AsyncAppender    (LOGBACK-1008)

• Added support for specifying the callstack depth range in the PatternLayout. For example, %caller{1..2}    displays the first two calls in the callstack.

• Added HTTP request method to MDCInsertingServletFilter.

• Fixed time-zone dependent code in RollingCalendarTest.    (LOGBACK-116)

• Simplified connection logic of SocketApender to reduce multi-threading    overhead and unnecessary instantiation of SocketConnector    objects.

• Fixed race condition in SMTPAppenderBase causing missing or    duplicate emails.    (LOGBACK-909)

• Fixed an issue with FileAppender in prudent mode, where    an interrupt could prevent further access to the file    (LOGBACK-875).

• Fixed IllegalStateException when multiple threads    write files to same directory    (LOGBACK-128).

• Changed queue consumption strategy in AbstractSocketAppender    from "take" to "peek/remove" in order to avoid losing an event on each socket    connection break. Zero is now a deprecated queue size. A queue size of one    should be taken instead to indicate synchronous processing.    (LOGBACK-977)

• RequestLogImpl now has an overridable configure    method to allow extending implementations to configure it via methods    other than the logback-access.xml file.

• Fixed a bug in AccessEvent which could cause any    AsyncAppender based appender to corrupt the request    headers, request parameters, or response headers, before logging.

• SQL scripts to setup your logback database are now provided as    JAR resources    (LOGBACK-948).

• Threads created internally by logback are now named    logback-n, where n is an integer. For the    first thread n is set to 1, for each successive thread    n is incremented by 1.

• Added max runtime parameter to AsyncAppender to allow    the appender to flush events, up to a maximum delay, during a stop    of the LoggerContext. This can be used to ensure that all queued    events are flushed.

• Added new configuration element shutdownHook to allow the    user to specify a ShutdownHook implementation that will stop the Logback    context upon JVM exit.

• BasicStatusManager now prevents adding more than    one instance of OnConsoleStatusListener as a status    listener. This fixes LOGBACK-976.

• TimeBasedRollingPolicy now accepts a time zone in    its %d conversion pattern. (LOGBACK-611)

• It is now possible to configure the character encoding used by    SyslogAppender to encode messages using the    setCharset() method. This fixes LOGBACK-732    

请注意：

所有 logback 模块要求 JDK 1.6，而不是 JDK 1.5！
