log42 如何自定义logger

自定义logger，个人理解就是：logger类里记录的日志单独打印到指定位置

自定义logger

@Slf4j
public class logUtils {
    public static void logInfo(String message) {
        log.info(message);
    }
}

Log4j2.xml 配置

<configuration status="info" monitorInterval="10">
    <properties>
        <property name="LOG_HOME">./applog/logsproperty>
        <Property name="FILE_NAME" value="practisesvr"/>
        <Property name="LOG_PATTERN"
                  value="[%d{yyyy-MM-dd HH:mm:ss.SSS_SSS}] [%-5p] [%thread] [%file:%line] → [%replace{%enc{%m}{CRLF}}{\\r|\\n|%0D|%0A|%0a|%0d}{}]%n"/>

使用

String apiJson = logUtils.buildApiJsonLog(request, response, executionCost);
logUtils.logInfo(apiJson);
