logback配置和使用

一、依赖包

<properties>
　　<logback.version>1.2.3logback.version>
properties>

<dependency>
    <groupId>ch.qos.logbackgroupId>
    <artifactId>logback-coreartifactId>
    <version>${logback.version}version>
dependency>
<dependency>
    <groupId>ch.qos.logbackgroupId>
    <artifactId>logback-classicartifactId>
    <version>${logback.version}version>
dependency>
<dependency>
    <groupId>ch.qos.logbackgroupId>
    <artifactId>logback-accessartifactId>
    <version>${logback.version}version>
dependency>

 

二、logback.xml

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



<configuration  scan="true" scanPeriod="30 seconds">
    
    <property resource="logback.properties" />

    <property name="FILE_LOG_PATTERN"

        <appender-ref ref="error_file"/>
    root>
    
    
    
    
 configuration>

 

三、logback.properties

# 应用名称
app.name=logback-test

# 日志存放地址
log.dir=logs

# 日志存放时间配置(单位:天)
debug.file.max.history=30
info.file.max.history=30
warn.file.max.history=30
error.file.max.history=30

# 日志文件存放上限制，超过指定值清除历史日志文件
debug.file.total.size.cap=1GB
info.file.total.size.cap=10GB
warn.file.total.size.cap=1GB
error.file.total.size.cap=1GB

# 单文件最大值
debug.file.max.file.size=100MB
info.file.max.file.size=100MB
warn.file.max.file.size=100MB
error.file.max.file.size=100MB

 

四、使用方式

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class App {
    
    public static Logger logger = LoggerFactory.getLogger(App.class);
    
    public static void main( String[] args ) {
        
        logger.debug( "logback {}", "debug" );
        logger.info( "logback {}", "info" );
        logger.warn( "logback {}", "warn" );
        logger.error( "logback {}", "error" );
        
    }
}
