根據類進行日誌文件隔離（將定時任務獨立出來）

一，logback-spring.xml

<configuration>
    <!-- 屬性文件:在properties文件中找到對應的配置項 -->
    <springProperty scope="context" name="logging.path"  source="logging.path"/>
    <springProperty scope="context" name="logging.level" source="logging.level.com.glmapper.spring.boot"/>
    <!-- 默認的控制檯日誌輸出，一般生產環境都是後臺啓動，這個沒太大作用 -->
    <appender name="STDOUT"
              class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <Pattern>%d{HH:mm:ss.SSS} %-5level %logger{80} - %msg%n</Pattern>
        </encoder>
    </appender>
    <!-- 錯誤日誌 appender ： 按照每天生成日誌文件 -->
    <appender name="ERROR-APPENDER" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <append>true</append>
        <!-- 過濾器，只記錄 error 級別的日誌 -->
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>error</level>
        </filter>
        <!-- 日誌名稱 -->
        <file>${logging.path}/glmapper-spring-boot/glmapper-error.log</file>
        <!-- 每天生成一個日誌文件，保存30天的日誌文件 -->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--日誌文件輸出的文件名:按天回滾 daily -->
            <FileNamePattern>${logging.path}/glmapper-spring-boot/glmapper-error.log.%d{yyyy-MM-dd}</FileNamePattern>
            <!--日誌文件保留天數-->
            <MaxHistory>30</MaxHistory>
        </rollingPolicy>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <!--格式化輸出：%d表示日期，%thread表示線程名，%-5level：級別從左顯示5個字符寬度%msg：日誌消息，%n是換行符-->
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
            <!-- 編碼 -->
            <charset>UTF-8</charset>
        </encoder>
    </appender>
    <!--特殊功能單獨appender 例如調度類的日誌-->
    <appender name="SCHEDULERTASKLOCK-APPENDER" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <append>true</append>
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>${logging.level}</level>
        </filter>
        <file>${logging.path}/glmapper-spring-boot/scheduler-task-lock.log</file>
        <!-- 每天生成一個日誌文件，保存30天的日誌文件 -->
        <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
            <!--日誌文件輸出的文件名:按天回滾 daily -->
            <FileNamePattern>${logging.path}/glmapper-spring-boot/scheduler-task-lock.log.%d{yyyy-MM-dd}</FileNamePattern>
            <!--日誌文件保留天數-->
            <MaxHistory>30</MaxHistory>
        </rollingPolicy>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <!--格式化輸出：%d表示日期，%thread表示線程名，%-5level：級別從左顯示5個字符寬度%msg：日誌消息，%n是換行符-->
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n</pattern>
            <!-- 編碼 -->
            <charset>UTF-8</charset>
        </encoder>
    </appender>

    <!--這裏指定到了具體的某一個類-->
    <logger name="com.example.demo.task.TraceTimeTask" level="${logging.level}" additivity="true">
        <appender-ref ref="SCHEDULERTASKLOCK-APPENDER" />
        <appender-ref ref="ERROR-APPENDER" />
    </logger>

    <root level="${logging.level}">
        <appender-ref ref="STDOUT"/>
    </root>
</configuration>

二、application.properties

#設置應用的日誌級別
logging.level.com.glmapper.spring.boot=INFO
#路徑
logging.path=./logs

三、定時任務類TraceTimeTask

package com.example.demo.task;
import com.example.demo.controller.TestController;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.scheduling.annotation.Scheduled;
import org.springframework.stereotype.Component;

import java.util.Date;
@Component
public class TraceTimeTask {
    private static final Logger LOGGER =
            LoggerFactory.getLogger(TraceTimeTask.class);
    @Scheduled(cron = "0 0/1 * * * ?")
    public void pushDataScheduled(){
        LOGGER.info("GLMAPPER-SERVICE:info");
        LOGGER.error("GLMAPPER-SERVICE:error");
        System.out.println("當前時間爲"+new Date());
        System.out.println(">>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>");
    }
}

四、啓動類開啓定時任務

package com.example.demo;

import org.mybatis.spring.annotation.MapperScan;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.scheduling.annotation.EnableScheduling;

@SpringBootApplication
@EnableScheduling
@MapperScan("com.example.demo.mapper")
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }

}
