log4j2关闭所有带有slf4j的附加器

Question

我需要一些关于log4j2配置的帮助。当我调试记录器时，它看起来像是关闭了所有的附加程序，然后我从来没有收到任何应用程序日志。幸运的是，我知道log4j至少是找到属性文件，并给记录器初始化调试输出。

这是我的日志4J2。属性文件：

status = debug
name = PropertiesConfig
filters = threshold

filter.threshold.type = ThresholdFilter
filter.threshold.level = info

appenders = console

appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = %d{yy-MM-dd HH:mm:ss:SSS} %-5p %c{1}:%L - %m%n

rootLogger.level = debug
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT

appender.file.type = File
appender.file.name = application
appender.file.fileName=${filename}/propertieslogs.log
appender.file.layout.type=PatternLayout
appender.file.layout.pattern=[%-5level] %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %c{1} - %msg%n

以下是记录器调试初始化输出：

感谢任何帮助！我需要它。

我真的很想让异步appender在某个时候工作，但是很难通过log4j2找到示例。log4j2的属性语法

还有-这是我的pom。xml:

Answer 1

我刚刚经历了一个类似的问题。在我的例子中，我能够接收应用程序日志，但使用的似乎是默认的log4j2配置。日志处于信息级别。未应用log4j2配置（XML）中为记录器设置的任何级别。我在OP发布的启动日志中看到了非常类似的输出，包括关于“关闭OutputStreamManager”的消息。

我的是一个Spring启动应用程序，我能够通过禁用Spring启动日志系统来解决这个问题。我将这个系统变量添加到我的启动命令中：-Dorg.springframework.boot.logging.LoggingSystem=no

一旦我这样做了，日志就按照我的log4j2 XML配置中设置的级别按预期工作。它似乎是Spring启动劫持了日志系统，而不是SLF4J和LOG4J2之间的冲突。

请注意，我仍然看到相同的日志启动消息——输出流管理器仍然在关闭。推测：这是正常行为，可能只是关闭打印log4j2初始化过程的引导记录器。

版本：

• log4j： 2.13.3
• slf4j： 1.7.30
• Spring启动：2.2.7-发布
