如何为spring 5实现log4j2配置文件

Question

我想用log4j2配置文件实现spring 5，比如dev、qa和prod。

目前，我是如何使用log4j2运行spring 5的，在命令行中加载log4j2属性

mvn tomcat8:run -Dlog4j.configurationFile=file:%path_to_log4j2_prop%/log4j2.properties

这是我的log4j2属性：

status = debug
name = PropertiesConfig
 
#Make sure to change log file path as per your need
property.environment=D:/WhiteCoats-New-Workspace/spring-5
property.servicesfilename = ${environment}/wc.out
 
filters = threshold
 
filter.threshold.type = ThresholdFilter
filter.threshold.level = debug
 
appenders = services
 
appender.services.type = RollingFile
appender.services.name = ServiceFile
appender.services.fileName = ${servicesfilename}
appender.services.filePattern = ${environment}/wc.out-%d{yyyy-MM-dd}-%i
appender.services.layout.type = PatternLayout
appender.services.layout.pattern = [ %d{yyyy-MMM-dd HH:mm:ss a} ] - [%t] %-5level %logger{36} - %msg%n
appender.services.policies.type = Policies
appender.services.policies.time.type = TimeBasedTriggeringPolicy
appender.services.policies.time.interval = 1
appender.services.policies.time.modulate = true
appender.services.policies.size.type = SizeBasedTriggeringPolicy
appender.services.policies.size.size=5MB
appender.services.strategy.type = DefaultRolloverStrategy
appender.services.strategy.max = 10

loggers = services
 
#services logs
 
logger.services.name = com.vm
logger.services.level = debug
logger.services.additivity = false
logger.services.appenderRef.services.ref = ServiceFile

rootLogger.level = info
rootLogger.appenderRef.stdout.ref = ServiceFile

在spring 3中，我使用了log4j并在web.xml中配置了路径。

如何为spring 5实现log4j2的概要文件？

Answer 1

在Spring中，如果您需要更改属性log4j.configurationFile，那么它在application.yml中非常简单。如果使用配置文件，则定义默认值和覆盖值。例如：

log4j:
    configurationFile: %path_to_log4j2_prop%
---
spring:
    profiles: development
log4j:
    configurationFile: %path_to_dev_log4j2_prop%
---
spring:
    profiles: production
log4j:
    configurationFile: %path_to_prod_log4j2_prop%

如果仅使用Spring，则可以使用@Configuration与@Profile和@PropertySource一起根据配置文件加载不同的属性文件，并且在这些文件中可以根据需要设置log4j.configurationFile属性。
