1.有时候需要用log4记录某些指定日志到指定文件中以便于分析
log4j.xml配置如下:
<?xml version="1.0" encoding="UTF-8"?><!-- status=debug 可以查看log4j的装配过程 --><configuration status="off" monitorInterval="1800">    <properties>        <property name="LOG_HOME">/data/wxApplogs</property>        <!-- 日志备份目录 -->        <property name="BACKUP_HOME">{LOG_HOME}/backup</property>        <property name="STAT_NAME">resources-app</property>        <!-- 服务模块名 -->        <property name="SERVER_NAME">resources-app</property>        <!-- 日志输出的项目名 -->        <property name="PROJECT_NAME">resources-app</property>    </properties>    <appenders>        <!-- 定义控制台输出 -->        <Console name="Console" target="SYSTEM_OUT" follow="true">            <PatternLayout pattern="%date{yyyy-MM-dd HH:mm:ss.SSS} %level [${PROJECT_NAME}] [%thread][%file:%line] - %msg%n" />        </Console>        <!-- 程序员调试日志 -->        <RollingRandomAccessFile name="DevLog" fileName="${LOG_HOME}/${STAT_NAME}/${SERVER_NAME}" filePattern="${LOG_HOME}/${SERVER_NAME}.%d{yyyy-MM-dd-HH}.log">            <PatternLayout pattern="%date{yyyy-MM-dd HH:mm:ss.SSS} %level [${PROJECT_NAME}] [%thread][%file:%line] - %msg%n" />            <Policies>                <TimeBasedTriggeringPolicy interval="1" modulate="true" />            </Policies>        </RollingRandomAccessFile>        <RollingRandomAccessFile name="FileName" fileName="${LOG_HOME}/${STAT_NAME}/${SERVER_NAME}_${STAT_NAME}_RedisErrorLog" filePattern="${LOG_HOME}/${SERVER_NAME}_${STAT_NAME}.%d{yyyy-MM-dd-HH}.log">            <MarkerFilter marker="REDISMARKER" onMatch="ACCEPT" onMismatch="DENY"/>            <PatternLayout pattern="%date{yyyy-MM-dd HH:mm:ss.SSS} %level [%thread][%file:%line] - %msg%n" />            <Policies>                <TimeBasedTriggeringPolicy interval="1" modulate="true" />            </Policies>        </RollingRandomAccessFile>    </appenders>    <loggers>        <!-- 3rdparty Loggers -->        <logger name="org.springframework.core" level="info">        </logger>        <logger name="org.springframework.beans" level="info">        </logger>        <logger name="org.springframework.context" level="info">        </logger>        <logger name="org.springframework.web" level="info">        </logger>        </logger>        <!-- Root Logger -->        <root level="DEBUG">            <appender-ref ref="DevLog" />            <appender-ref ref="Console" />            <appender-ref ref="FileName" />        </root>    </loggers></configuration>
Java代码如下:
/** * 指定文件存储日志 */private Logger logSpcifyFile = LogManager.getLogger("FileName");//指定xml中定义的文件名

logSpcifyFile.info("指定日志");
就这样简单解决!!!
