SSM下log4j2 记录日志

SSM环境下使用log4j2  需导入包

<dependency>  <groupId>org.apache.logging.log4j</groupId>  <artifactId>log4j-core</artifactId>  <version>2.9.0</version></dependency><dependency>  <groupId>org.apache.logging.log4j</groupId>  <artifactId>log4j-slf4j-impl</artifactId>  <version>2.9.0</version></dependency>

在classpath下需创建log4j2.xml

<?xml version="1.0" encoding="UTF-8"?><!--设置log4j2的自身log级别为DEBUG--><configuration status="DEBUG ">    <appenders>    <!-- 控制台输出 -->        <console name="Console" target="SYSTEM_OUT">            <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} [%t] %-5level %logger{36} - %n%msg%n"/>        </console><!-- fileName：输出路径  filePattern：命名规则 -->        <RollingFile name="RollingFileInfo" fileName="D:\\demo\\allOut.log"                     filePattern="D:\\demo\\$${date:yyyy-MM-dd}/allOut-%d{yyyy-MM-dd}-%i.log.gz">            <Filters>                <ThresholdFilter level="all" onMatch="ACCEPT" onMismatch="DENY"/>            </Filters>            <!-- 输出格式 -->            <PatternLayout pattern="%d{yyyy-MM-dd HH:mm:ss} [%t] %-5level %logger{36} - %msg%n"/>            <Policies>                <TimeBasedTriggerzingPolicy interval="1"/>                <!-- SizeBasedTriggeringPolicy单个文件的大小限制 -->                <SizeBasedTriggeringPolicy size="2 MB"/>            </Policies>            <!-- DefaultRolloverStrategy同一个文件下的最大文件数 -->            <DefaultRolloverStrategy max="50"/>        </RollingFile>      <!--   <RollingFile name="RollingFileWarn" fileName="${sys:user.home}/logs/hpaasvc/warn.log"                     filePattern="${sys:user.home}/logs/hpaasvc/$${date:yyyy-MM}/warn-%d{yyyy-MM-dd}-%i.log">            <Filters>                <ThresholdFilter level="WARN"/>                <ThresholdFilter level="ERROR" onMatch="DENY" onMismatch="NEUTRAL"/>            </Filters>            <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>            <Policies>                <TimeBasedTriggeringPolicy/>                <SizeBasedTriggeringPolicy size="100 MB"/>            </Policies>        </RollingFile>        <RollingFile name="RollingFileError" fileName="${sys:user.home}/logs/hpaasvc/error.log"                     filePattern="${sys:user.home}/logs/hpaasvc/$${date:yyyy-MM}/error-%d{yyyy-MM-dd}-%i.log">            <ThresholdFilter level="ERROR"/>            <PatternLayout pattern="[%d{HH:mm:ss:SSS}] [%p] - %l - %m%n"/>            <Policies>                <TimeBasedTriggeringPolicy/>                <SizeBasedTriggeringPolicy size="100 MB"/>            </Policies>        </RollingFile> -->    </appenders>    <loggers>        <!--过滤掉spring和hibernate的一些无用的debug信息-->        <logger name="org.springframework" level="INFO">        </logger>        <logger name="org.hibernate" level="INFO">        </logger>        <root level="all">            <appender-ref ref="Console"/>            <appender-ref ref="RollingFileInfo"/>         <!--    <appender-ref ref="RollingFileWarn"/>            <appender-ref ref="RollingFileError"/> -->        </root>    </loggers></configuration>

简单的日志控制基类

import org.apache.logging.log4j.LogManager;import org.apache.logging.log4j.Logger;/** * 日志记录基类 * @author Administrator * */public abstract class BaseLogController {private static Logger logger = LogManager.getLogger();public BaseLogController() {}//级别从高到低：FATAL、ERROR、WARN、INFO、DEBUG、TRACEpublic void fatal(Object message){logger.fatal(message);}public void error(Object message){logger.error(message);}public void warn(Object message){logger.warn(message);}public void info(Object message){logger.info(message);}public void debug(Object message){logger.debug(message);}public void trace(Object message){logger.trace(message);}}
