springboot + logback 日志简单配置

1.首先确保存在依赖

slf4j-api-x.x.x.jar和logback-classic-x.x.x.jar

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
</dependency>
<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
</dependency>

2.在application.properties或application.yml中添加配置

logging.config=classpath:logback-spring.xml

3.在resources目录下创建配置文件logback-spring.xml

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

<configuration scan="true" scanPeriod="60 seconds">

    <property name="log.path" value="F:/logs" />

    <appender name="zxing" class="ch.qos.logback.core.rolling.RollingFileAppender">
        <file>${log.path}/zxing/zxing.log</file>
        <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
            <fileNamePattern>${log.path}/zxing/zxing-%d{yyyy-MM-dd}.%i.log</fileNamePattern>
            <maxFileSize>10MB</maxFileSize>
            <maxHistory>10</maxHistory>
            <totalSizeCap>100MB</totalSizeCap>
        </rollingPolicy>
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{36} -%msg%n</pattern>
        </encoder>
    </appender>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{35} -%msg%n</pattern>
        </encoder>
    </appender>

    <logger name="com.ygq.zxing" level="INFO" additivity="false">
        <appender-ref ref="zxing" />
        <appender-ref ref="STDOUT" />
    </logger>

</configuration>

4.代码中使用如下方式获取日志类

Logger logger = LoggerFactory.getLogger(类名.class);
