SpringBoot1.3.5 (gradle)的Log4j 2.6 (属性文件)无法工作

Question

我一直在尝试使用SpringBoot1.3.5版本的Log4j 2.6 (属性文件)，并且使用Spring的默认日志记录。我还没能找到确切的问题。

下面是我的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

我已经研究过多个这样的主题，并且似乎正确地设置了所有属性。但是，我无法了解为什么它没有按照我的配置记录到文件和控制台。

当我创建应用程序时，将创建log4j2.properties文件中配置的空日志文件logs/ingestion.log。

Answer 1

我似乎遗漏了在application.properties文件中包含日志配置文件参数，因为它检测和加载了log4j，没有任何错误，但是spring没有使用。

添加下面一行解决了这个问题。

logging.config= # location of logging config file

P.S.：找到了解决我的问题的方法：log4j2.xml loaded but not applied [JVM argument]

Answer 2

如果使用Spring，则可以在application.properties或application.yml中配置日志记录。

yml配置

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

属性配置

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