Log4j2配置最佳实践

1、日志包maven依赖

<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-api</artifactId>
    <version>2.7</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-core</artifactId>
    <version>2.7</version>
</dependency>
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-slf4j-impl</artifactId>
    <version>2.7</version>
</dependency>

2、日志配置文件

<?xml version="1.0" encoding="UTF-8"?>
<configuration status="warn">
    <appenders>
        <Console name="Console" target="SYSTEM_OUT" follow="true">
            <PatternLayout pattern="%d{yyyy/MM/dd HH:mm:ss.SSS} %t [%p] %c{1} (%F:%L) %msg%n" />
        </Console>

        <XMDFile name="ShepherdLog" fileName="shepherd.log"/>

        <!--XMDFile异步磁盘日志配置示例-->
        <!--默认按天&按512M文件大小切分日志，默认最多保留30个日志文件。-->
        <!--注意：fileName前会自动增加文件路径，只配置文件名即可-->
        <XMDFile name="LocalServiceLog" fileName="request.log"/>

        <Scribe name="LogCenterSync">
            <!-- 在指定日志名方面，scribeCategory 和 appkey 两者至少存在一种，且 scribeCategory 高于 appkey。-->
            <!-- <Property name="scribeCategory">data_update_test_lc</Property> -->
            <LcLayout/>
        </Scribe>
        <Async name="LogCenterAsync" blocking="false">
            <AppenderRef ref="LogCenterSync"/>
        </Async>
    </appenders>

    <loggers>
        <AsyncLogger name="com.sankuai.shepherd" level="info" additivity="false">
            <AppenderRef ref="ShepherdLog" level="warn"/>
            <AppenderRef ref="LogCenterAsync" level="info"/>
        </AsyncLogger>

        <root level="info">
            <!--Console日志是同步、阻塞的，推荐只在本地调试时使用，线上将该配置去掉-->
            <!--appender-ref ref="Console" /-->
            <appender-ref ref="LocalServiceLog"/>
            <appender-ref ref="LogCenterAsync"/>
        </root>
    </loggers>
</configuration>
