自定义附加器的log4j2属性文件

Question

我创建了一个自定义追加器，但在运行测试时没有调用它。以下是这些属性的外观：

name=config
appenders=console, myCustomAppender

appender.console.type=Console
appender.console.name=STDOUT
appender.console.layout.type=PatternLayout
#appender.console.layout.pattern =%d{HH:mm:ss} [%t] %c{1} [%-5level] - %msg%n
appender.console.layout.pattern=%d{dd-MM-yyyy HH:mm:ss} [%-5p] (%F:%L) - %m%n

appender.myCustomAppender = com.myCompany.logging.log4j.WindowsEventLogAppender
appender.myCustomAppender.name = WindowsEventLogAppender
appender.myCustomAppender.type = WindowsEventLogAppender

rootLogger.level=info
rootLogger.appenderRefs=stdout, myCustomAppender
rootLogger.appenderRef.stdout.ref=STDOUT

我的appender被称为WindowsEventLogappender。知道我的档案有什么问题吗？我看到了控制台测试消息，但没有看到来自我的appender的消息。现在我只是在我的自定义追加器中做一个system.out.println来验证它是否被调用。

我在这里可能会很晚，但我想我的答案可以帮助其他寻找答案的人。请接受这个答案，如果这是正确的！

如果您创建了带有如下注释的自定义追加器：

@Plugin(name = "MyCustomAppender", category = "Core", 
elementType = "appender", printObject = true)
public final class MyCustomAppenderImpl extends AbstractAppender {
  // other code for the plugin....
}

关于配置附加器的log4j2手册指出：

（注意：我添加了一个stdout（console）appender，只是为了显示与OOTB appender的相关性/相似性，并添加了两个RootLogger和一个自定义记录器的示例用法）

# this packages attribute is important, please put comma seperated package(s) to the 
# plugin(s) you have created
packages = com.package.to.your.plugin

# Example: Declare and Define OOTB Console appender, which sends log events to stdout
appender.console.name = stdout
appender.console.type = Console

# Declare and define the custom appender like this
# Note that the "abc" in "appender.abc.type" can be anything
# and the value for "appender.abc.type" should be the same as 
# "Name" attribute value given in custom appender plugin which is "MyCustomAppender"
appender.abc.name=arbitrary_name
appender.abc.type=MyCustomAppender

rootLogger.appenderRef.stdout.ref = stdout
rootLogger.appenderRef.abc.ref = arbitrary_name    

logger.loggeridentifier.name = com.test.SomeClass
logger.loggeridentifier.appenderRef.stdout.ref = stdout
logger.loggeridentifier.appenderRef.abc.ref = arbitrary_name

# Also note that the value of appenderRef should be the same name given to your 
# appender in properties file, which in this case is "arbitrary_name" (as given above)
