    Apache Log4j 2.7 发布了，Log4j是Apache的一个开放源代码项目，通过使用Log4j，我们可以控制日志信息输送的目的地是控制台、文件、GUI组件、甚至是套接口服务 器、NT的事件记录器、UNIX Syslog守护进程等;我们也可以控制每一条日志的输出格式;通过定义每一条日志信息的级别，我们能够更加细致地控制日志的生成过程。最令人感兴趣的就是，这些可以通过一个配置文件来灵活地进行配置，而不需要修改应用的代码。

    部分更新内容：

    新特性:
    o LOG4J2-1578: RoutingAppender can be configured with scripts. Add Script in a Routes element.

    o LOG4J2-1597: Add a ScriptAppenderSelector to create an Appender specified by a Script.

    o LOG4J2-1349: (GC) Added support for garbage-free ThreadContext map. Disabled by default,
    users need to enable this explicitly.
    o LOG4J2-1447: (GC) Changed LogEvent's internal data structure for context data to be garbage-free.
    Added method LogEvent#getContextData(), deprecated method #getContextMap().
    o LOG4J2-1010: Users can now inject context data from other sources than ThreadContext. Values
    can be any Object, not just Strings. Thanks to Mikael Ståldal.
    o LOG4J2-1568: Added support for java.util.concurrent.LinkedTransferQueue to AsyncAppender.

    Bugs 修复:
    o LOG4J2-1618: Fixed ClassCastException when using JUL logging during shutdown. Thanks to
    Raman Gupta.
    o LOG4J2-1620: 2.7-rc1: RollingFileAppender immediateFlush default value should be true,
    not false. Thanks to Sascha Scholz.
    o LOG4J2-1611: Improved performance of context data injector for web applications to be on
    par with standalone applications.
    o LOG4J2-1591: Introduced new interface LifeCycle2 with stop(long,TimeUnit) method to avoid
    breaking backwards compatibility with new Configurator.shutdown(LoggerContext, long, TimeUnit)
    API.
    o LOG4J2-1590: Fixed issue with filters extending AbstractFilter that did not override methods
    with unrolled varargs.
    o LOG4J2-1583: Fixed scrambled log messages triggered by nested logging from toString() method
    of a logging parameter object. Thanks to Larry West.
    o LOG4J2-1259: Log4j threads are no longer leaking on Tomcat shutdown. Thanks to Misagh Moayyed,
    Steffen Offermann.
    o LOG4J2-1051: When starting on Google App Engine, Interpolator now suppresses the NoClassDefFoundError
    stack trace for the jvmrunargs lookup. Thanks to Lukasz Lenart.
    o LOG4J2-1582: When initializing on platforms where JMX is not available, Interpolator component
    no longer prints stack trace for warning messages.
    o LOG4J2-1581: Unregistering JMX components no longer prints a stack trace when the MBean
    has already been unregistered.
    o LOG4J2-1313: Support Property values to be specified in configuration as a value attribute
    as well as an element. Thanks to Philipp Knobel, Leon Finker.
    o LOG4J2-1575: (GC) LoggerConfig now stores configuration properties in a List, not a Map
    to prevent creating temporary Iterator objects. Added method LoggerConfig#getPropertyList(),
    deprecated method #getProperties().
    o LOG4J2-1457: Fixed class loader deadlock when using async logging and extended stack trace
    pattern. Thanks to Leon Finker.
    o LOG4J2-1563: Fix to prevent Log4j 2.6.2 and higher from losing exceptions when a security
    manager is present. Thanks to Jason Tedor.
    o LOG4J2-1530: Fixed issue where LogEvent.getContextStack() returned null.
    o LOG4J2-1518: Prevent deadlock in Async Loggers when queue is full and logged Object's toString()
    logs another message. Thanks to Leon Finker.
    o LOG4J2-1542: Prevent ArrayIndexOutOfBoundsException in ParameterizedMessage.formatTo for
    single-char or empty messages. Thanks to Rogério Lecarião Leite.
    o LOG4J2-1549: Fixed issue where AsyncLoggerContextSelector+PropertiesConfigurationBuilder
    defaulted to includeLocation=true. Thanks to Jason Bedard.

    o LOG4J2-1538: Prevent NPE when dynamically removing filters. Thanks to Igor Karpov.
    o LOG4J2-1532: Attributes were not merged properly in composite configurations.
