SpringBoot集成Log4j2

1.在 pom.xml 中添加 Log4j 2.x 的依赖：

<dependency>
    <groupId>org.apache.logging.log4jgroupId>
    <artifactId>log4j-slf4j-implartifactId>
    <version>2.17.1version>
dependency>

2.在 resources 中配置 Log4j2.xml：

<Configuration status="WARN" monitorInterval="60">
    
    <Properties>
        
        <Property name="log_base_dir">/app_data/logs/my_appProperty>
        
        <Property name="log_pattern">[%d{yyyy-MM-dd HH:mm:ss.SSS}][%-5p][%T][%c.%M:%L] %msg%xEx%nProperty>
        
        <Property name="max_single_file_size">1MBProperty>
    Properties>
 
    
    <Appenders>
        
        <Console name="Console" target="SYSTEM_OUT">
            
            <ThresholdFilter level="DEBUG" onMatch="ACCEPT" onMismatch="DENY"/>
            
            <PatternLayout pattern="${log_pattern}"/>
        Console>
 
        
        
        <RollingFile name="DebugLogRollingFile" fileName="${log_base_dir}/my_app_debug.log"
                     filePattern="${log_base_dir}/$${date:yyyy_MM_dd}/my_app_debug_%d{yyyy_MM_dd_HH}_%i.log.gz">
            <ThresholdFilter level="DEBUG" onMatch="ACCEPT" onMismatch="DENY"/>
            <PatternLayout pattern="${log_pattern}" charset="UTF-8"/>
            
            <Policies>
                
                <TimeBasedTriggeringPolicy interval="1" modulate="false"/>
                
                <SizeBasedTriggeringPolicy size="${max_single_file_size}"/>
            Policies>
