引入jar包
此处如果是引用了spring boot则不需要再引一下的jar包了,spring boot中已集成了这些包
<!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-api --> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>2.0.0-alpha1</version> </dependency> <!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-core --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-core</artifactId> <version>1.3.0-alpha5</version> </dependency> <!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-classic --> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.3.0-alpha5</version> </dependency>
配置文件的位置
在resource文件夹配置logback.xml
<?xml version="1.0" encoding="UTF-8"?> <configuration scan="true" scanPeriod="60 seconds" debug="false"> <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n </pattern> </encoder> </appender> <property name="LOG_HOME" value="D:/logback" /> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <encoder> <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n lvchengda</pattern> <charset>utf-8</charset> </encoder> <file>${LOG_HOME}/log/output.log</file> <rollingPolicy class="ch.qos.logback.core.rolling.FixedWindowRollingPolicy"> <fileNamePattern>${LOG_HOME}/log/output.log.%i</fileNamePattern> </rollingPolicy> <triggeringPolicy class="ch.qos.logback.core.rolling.SizeBasedTriggeringPolicy"> <MaxFileSize>1kb</MaxFileSize> </triggeringPolicy> <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy"> <fileNamePattern>${LOG_HOME}/logs/aa.%d{yyyy-MM-dd}.%i.log.zip</fileNamePattern> <maxFileSize>50MB</maxFileSize> <!-- 日志文件过大会使的编辑器打开非常慢,因此设置日志最大50MB --> <maxHistory>30</maxHistory> <!-- 保存30天 --> <totalSizeCap>10GB</totalSizeCap> <!-- 总日志大小 --> </rollingPolicy> </appender> <root level="INFO"> <appender-ref ref="CONSOLE" /> <appender-ref ref="FILE" /> </root> </configuration>
代码运用:
import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class TestLog { static Logger logger = LoggerFactory.getLogger(TestLog.class); public static void main(String[] arge){ logger.debug("taiyonghai debug"); logger.info("taiyonghai info"); logger.error("taiyonghai error"); logger.warn("taiyonghai warn"); } }
