Apache karaf4.2.3 - 每个包的单独日志文件

Question

如何使用pax日志记录为karaf-4.2.3中部署的每个bundle创建一个单独的日志文件，该日志文件具有log4j2本机样式配置？

我试过路由appender，但没有结果。

我将每个捆绑日志写在一个单独的日志文件中以便于调试。

我不知道自动这样做。但是你可以做的是为每个模块创建一个基于根包名称的单独配置

log4j2.logger.xy.name = com.company.module.xy
log4j2.logger.xy.level = INFO
log4j2.logger.xy.additivity = false
log4j2.logger.xy.appenderRef.inovel.ref = XyFile

log4j2.logger.zz.name = com.company.module.zz
log4j2.logger.zz.level = INFO
log4j2.logger.zz.additivity = false
log4j2.logger.zz.appenderRef.inovel.ref = ZzFile

log4j2.logger.keycloak.name = org.keycloak
log4j2.logger.keycloak.level = INFO
log4j2.logger.keycloak.additivity = false
log4j2.logger.keycloak.appenderRef.keycloak.ref = KeycloakFile

参考可能看起来像

# keyclok file appender
log4j2.appender.keycloak.type = RollingRandomAccessFile
log4j2.appender.keycloak.name = KeycloakFile
log4j2.appender.keycloak.fileName = ${karaf.data}/log/keycloak.log
log4j2.appender.keycloak.filePattern = ${karaf.data}/log/keycloak.log.%i
log4j2.appender.keycloak.append = true
log4j2.appender.keycloak.layout.type = PatternLayout
log4j2.appender.keycloak.layout.pattern = %d{ISO8601}
log4j2.appender.keycloak.policies.type = Policies
log4j2.appender.keycloak.policies.size.type = SizeBasedTriggeringPolicy
log4j2.appender.keycloak.policies.size.size = 8MB
log4j2.appender.keycloak.strategy.type = DefaultRolloverStrategy
log4j2.appender.keycloak.strategy.max = 10

这是很多手工工作。所以也许有人想出一个自动配置

只需看看每个Karaf发行版附带的official Log4j 2.x configuration，并查看评论的“路由”部分。

例如。我在我的一个项目中使用了以下内容：

# Root logger
log4j2.rootLogger.level = INFO
log4j2.rootLogger.appenderRef.RollingFile.ref = RollingFile
log4j2.rootLogger.appenderRef.RollingFile.filter.threshold.type = ThresholdFilter
log4j2.rootLogger.appenderRef.RollingFile.filter.threshold.level = WARN
log4j2.rootLogger.appenderRef.PaxOsgi.ref = PaxOsgi
log4j2.rootLogger.appenderRef.Console.ref = Console
log4j2.rootLogger.appenderRef.Console.filter.threshold.type = ThresholdFilter
log4j2.rootLogger.appenderRef.Console.filter.threshold.level = ${karaf.log.console:-OFF}

# Enable log routing...
log4j2.rootLogger.appenderRef.Routing.ref = Routing

# Loggers configuration

...

# Configure the routing (pay close attention to the escapes)...
log4j2.appender.routing.type = Routing
log4j2.appender.routing.name = Routing
log4j2.appender.routing.routes.type = Routes
log4j2.appender.routing.routes.pattern = \$\$\\\{ctx:bundle.name\}
log4j2.appender.routing.routes.bundle.type = Route
log4j2.appender.routing.routes.bundle.appender.type = RollingRandomAccessFile
log4j2.appender.routing.routes.bundle.appender.name = Bundle-\$\\\{ctx:bundle.name\}
log4j2.appender.routing.routes.bundle.appender.fileName = ${karaf.data}/log/bundle-\$\\\{ctx:bundle.name\}.log
log4j2.appender.routing.routes.bundle.appender.filePattern = ${karaf.data}/log/bundle-\$\\\{ctx:bundle.name\}.log.%d{yyyy-MM-dd}
log4j2.appender.routing.routes.bundle.appender.append = true
log4j2.appender.routing.routes.bundle.appender.layout.type = PatternLayout
log4j2.appender.routing.routes.bundle.appender.layout.pattern = ${log4j2.pattern}
log4j2.appender.routing.routes.bundle.appender.policies.type = Policies
log4j2.appender.routing.routes.bundle.appender.policies.time.type = TimeBasedTriggeringPolicy
log4j2.appender.routing.routes.bundle.appender.strategy.type = DefaultRolloverStrategy
log4j2.appender.routing.routes.bundle.appender.strategy.max = 31

这显然对我有用。我甚至不会想到OSGi中的静态配置！ ;-)
