使用Spring Boot 1.3.5（gradle）的Log4j 2.6（属性文件）不起作用

Question

我一直在尝试将Log4j 2.6 （属性文件）与Spring Boot 1.3.5版本一起使用 ，并且Spring的默认日志记录开始了。我一直无法找出确切的问题。

这是我的build.gradle文件：

buildscript {
    repositories {
        maven {
            url "https://plugins.gradle.org/m2/"
        }
    }
    dependencies {
        classpath "org.jfrog.buildinfo:build-info-extractor-gradle:3.1.1"
        classpath 'org.ajoberstar:gradle-git:1.3.0-milestone.1'
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.3.3.RELEASE") 
    }
}

...

dependencies {
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-web', version: '1.3.5.RELEASE'
    providedRuntime group: 'org.springframework.boot', name: 'spring-boot-starter-tomcat', version: '1.3.5.RELEASE'

    compile group: 'org.springframework.boot', name: 'spring-boot-starter-actuator', version: '1.3.5.RELEASE'
    compile group: 'org.apache.kafka', name: 'kafka-clients', version: '0.10.1.0'
    compile group: 'org.springframework.boot', name: 'spring-boot-starter-log4j2', version: '1.3.5.RELEASE'

    compile group: 'org.apache.logging.log4j', name: 'log4j-api', version: '2.6'
    compile group: 'org.apache.logging.log4j', name: 'log4j-core', version: '2.6'

    testCompile group: 'org.testng', name: 'testng', version: '6.8.8'
    testCompile group: 'org.json', name: 'json', version: '20160212'
    testCompile 'org.glassfish.jersey.core:jersey-client:2.22.2'
    testCompile group: 'org.springframework.boot', name: 'spring-boot-starter-test', version: '1.3.5.RELEASE'
    testCompile group: 'org.apache.kafka', name: 'kafka_2.11', version: '0.10.1.0'
}

configurations {
    all*.exclude module: 'spring-boot-starter-logging'
    providedRuntime
}

这是我的log4j2.properties文件：

name = PropertiesConfig

property.logDir = logs
property.filename = ingestion
property.pattern = %d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n

appenders = console, rolling

appender.console.type = Console
appender.console.name = STDOUT
appender.console.layout.type = PatternLayout
appender.console.layout.pattern = ${pattern}

appender.rolling.type = RollingFile
appender.rolling.name = RollingFile
appender.rolling.fileName = ${logDir}/${filename}.log
appender.rolling.filePattern = ${logDir}/${filename}.%d{yyyy-MM-dd}.log.gz
appender.rolling.layout.type = PatternLayout
appender.rolling.layout.pattern = ${pattern}
appender.rolling.policies.type = Policies
appender.rolling.policies.time.type = TimeBasedTriggeringPolicy
appender.rolling.policies.time.interval = 2
appender.rolling.policies.time.modulate = true
appender.rolling.policies.size.type = SizeBasedTriggeringPolicy
appender.rolling.policies.size.size=100MB
appender.rolling.strategy.type = DefaultRolloverStrategy
appender.rolling.strategy.max = 5

loggers = rolling

logger.rolling.name = com.dir.mysubdir
logger.rolling.level = WARN
#logger.rolling.additivity = false
logger.rolling.appenderRefs = rolling
logger.rolling.appenderRef.rolling.ref = RollingFile

# Root logger option
rootLogger.level = WARN
rootLogger.appenderRefs = stdout
rootLogger.appenderRef.stdout.ref = STDOUT

我研究了多个SO主题，并且似乎正确设置了所有属性。 但是有些我无法找出为什么它没有按照我的配置记录到文件和控制台。

引导运行应用程序时，将创建在log4j2.properties文件中配置的空日志文件logs / ingestion.log。

Answer 1

如果您使用的是Spring Boot，则可以在application.properties或application.yml配置日志记录。

yml配置

logging:
    file: server.log
    level:
         'com.myapp': INFO

属性配置

logging.file=server.log
logging.level.com.myapp=INFO

有关更多详细信息，请参见http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html

好像我错过了在application.properties文件中包括日志记录配置文件参数一样，由于这个原因，检测到并装入了log4j时没有任何错误，但是spring-boot并未使用它。
添加以下行即可解决此问题。

logging.config= # location of logging config file
