logback将日志写入不同文件夹里

转载：logback不同业务的日志打印到不同文件

一、logback.xml文件配置如下：

<?xml version="1.0" encoding="UTF-8" ?>

<configuration>

    <contextName>nana</contextName>

    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">

        <encoder>

            <Pattern>[%d{HH:mm:ss.SSS}] [%5level] [%thread] %logger{36} %msg%n</Pattern>

            <charset>UTF-8</charset>

        </encoder>

    </appender>

    <appender name="INFO_NANA" class="ch.qos.logback.core.rolling.RollingFileAppender">

        <file>../normalInfo.log</file>

        <encoder>

            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>

            <charset>UTF-8</charset>

        </encoder>

        <!--过滤器,只打INFO级别的日志-->

        <filter class="ch.qos.logback.classic.filter.LevelFilter">

        </filter>

        <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">

            <minIndex>1</minIndex>

        </rollingPolicy>

        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">

            <maxFileSize>10MB</maxFileSize>

        </triggeringPolicy>

    </appender>

    <appender name="ERROR_NANA" class="ch.qos.logback.core.rolling.RollingFileAppender">

            <charset>UTF-8</charset>

        </encoder>

        <!--过滤器,只打ERROR级别的日志-->

        <filter class="ch.qos.logback.classic.filter.LevelFilter">

            <level>ERROR</level>

            <onMatch>ACCEPT</onMatch>

            <onMismatch>DENY</onMismatch>

        </filter>

        <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">

            <fileNamePattern>normalError.%i.log</fileNamePattern>

            <minIndex>1</minIndex>

            <maxIndex>3</maxIndex>

        </rollingPolicy>

        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">

        </triggeringPolicy>

    </appender>

    <!--不同业务逻辑的日志打印到不同文件-->

    <appender name="FIRST_NANA" class="ch.qos.logback.core.rolling.RollingFileAppender">

        <file>../firstInfo.log</file>

        <encoder>

            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>

            <charset>UTF-8</charset>

        </encoder>

        <filter class="ch.qos.logback.classic.filter.LevelFilter">

            <level>INFO</level>

            <onMatch>ACCEPT</onMatch>

            <onMismatch>DENY</onMismatch>

        </filter>

        <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">

            <fileNamePattern>firstInfo.%i.log</fileNamePattern>

            <minIndex>1</minIndex>

            <maxIndex>3</maxIndex>

        </rollingPolicy>

        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">

    </appender>

    <appender name="SECOND_NANA" class="ch.qos.logback.core.rolling.RollingFileAppender">

        <encoder>

            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>

            <charset>UTF-8</charset>

        </encoder>

        <filter class="ch.qos.logback.classic.filter.LevelFilter">

            <level>INFO</level>

            <onMatch>ACCEPT</onMatch>

            <onMismatch>DENY</onMismatch>

        </filter>

        <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy">

            <fileNamePattern>secondInfo.%i.log</fileNamePattern>

            <minIndex>1</minIndex>

            <maxIndex>3</maxIndex>

        </rollingPolicy>

        <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy">

            <maxFileSize>10MB</maxFileSize>

        </triggeringPolicy>

    </appender>


　　 <!-- 不同的业务逻辑日志打印到指定文件夹-->

    <logger name="first" level="info" additivity="false">

        <appender-ref ref="FIRST_NANA"/>

    </logger>

    <logger name="second" level="info" additivity="false">

        <appender-ref ref="SECOND_NANA"/>

    </logger>

    <!--info和error分开打印-->

    <root level="INFO">

        <appender-ref ref="STDOUT"/>

        <appender-ref ref="INFO_NANA"/>

        <appender-ref ref="ERROR_NANA"/>

    </root>

</configuration>

二、工具类配置：

创建与logback.xml的logger名相对应的对象：

public enum LogFileName {

    // 与logback.xml的logger name 相同

    FIRST("first"),

    SECOND("second");

    private String logFileName;

    LogFileName(String fileName) {

        this.logFileName = fileName;

    }

    public String getLogFileName() {

        return logFileName;

    }

    public void setLogFileName(String logFileName) {

        this.logFileName = logFileName;

    }

    public static LogFileName getAwardTypeEnum(String value) {

        LogFileName[] arr = values();

        for(LogFileName item : arr) {

            if(null != item && StringUtils.isNotBlank(item.logFileName)) {

                return item;

            }

        }

        return null;

    }

}

指定logger日志存储路径，工具类：

public class LoggerUtil {

    public static <T> Logger logger(Class<T> clazz) {

        return LoggerFactory.getLogger(clazz);

    }

    /**

     * 打印到指定的文件下

     * @param desc 日志文件名称

     * @return

     */

    public static Logger logger(LogFileName desc) {

        return LoggerFactory.getLogger(desc.getLogFileName());

    }

}

测试如下：

@RestController

public class UserController {

    Logger FIRST_LOG = LoggerUtil.logger(LogFileName.FIRST);

    Logger SECOND_LOG = LoggerUtil.logger(LogFileName.SECOND);

    @RequestMapping("/bb")

    public String bb() {

        FIRST_LOG.info("firsthaha");

        SECOND_LOG.info("secondhaha");

        return "bb";

    }

}

结果如下图：
