配置

YAML语法

原文地址

Log4j还支持使用YAML配置文件。 该结构遵循与XML和YAML配置格式相同的模式。 例如：

Configuration:
  status: warn
  name: YAMLConfigTest
  properties:
    property:
      name: filename
      value: target/test-yaml.log
  thresholdFilter:
    level: debug
  appenders:
    Console:
      name: STDOUT
      PatternLayout:
        Pattern: "%m%n"
    File:
      name: File
      fileName: ${filename}
      bufferedIO: false
      PatternLayout:
        Pattern: "%d %p %C{1.} [%t] %m%n"
    List:
      name: List
      Filters:
        ThresholdFilter:
          level: error

  Loggers:
    logger:
      -
        name: org.apache.logging.log4j.test1
        level: debug
        additivity: false
        ThreadContextMapFilter:
          KeyValuePair:
            key: test
            value: 123
        AppenderRef:
          ref: STDOUT
      -
        name: org.apache.logging.log4j.test2
        level: debug
        additivity: false
        AppenderRef:
          ref: File
    Root:
      level: error
      AppenderRef:
        ref: STDOUT

为了使用YAML配置文件，必须包括Jackson YAML数据格式：

<dependency>
    <groupId>com.fasterxml.jackson.dataformat</groupId>
    <artifactId>jackson-dataformat-yaml</artifactId>
    <version>2.8.5</version>
</dependency>
