Java项目 使用Logback

添加依赖

<dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.2.3</version>
    <scope>test</scope>
</dependency>

<dependency>
    <groupId>org.slf4j</groupId>
    <artifactId>slf4j-api</artifactId>
    <version>1.7.30</version>
</dependency>

2.在src/main/resource 目录下 新建logback配置文件 即可 如下 ：logback.xml

一定是 src/main/resource 目录 src/main/resources 目录不起作用（多了s）

<?xml version="1.0" encoding="UTF-8"?>
 <configuration scan="true" scanPeriod="10 seconds">
 
 
    <property name="LOG_HOME" value="./logs" />
 
    <property name="LOG_PATTERN"  value="%d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n" />
 
    <!--输出到控制台 -->
    <appender name="STDOUT"  class="ch.qos.logback.core.ConsoleAppender">
        <filter class="ch.qos.logback.classic.filter.ThresholdFilter">
            <level>info</level>
        </filter>
        <encoder>
            <pattern>${LOG_PATTERN}</pattern>
            <charset>UTF-8</charset>
        </encoder>
    </appender>
 
 
    <!--输出到文件 -->
    <appender name="FILE"  class="ch.qos.logback.core.rolling.RollingFileAppender">
         <rollingPolicy class="ch.qos.logback.core.rolling.SizeAndTimeBasedRollingPolicy">
                        <FileNamePattern>${LOG_HOME}/project-name.%d{yyyy-MM-dd}.%i.log</FileNamePattern>
                        <MaxHistory>30</MaxHistory>
                        <MaxFileSize>10MB</MaxFileSize>
                 </rollingPolicy>
        <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
            <pattern>${LOG_PATTERN}</pattern>
            <charset>UTF-8</charset>
        </encoder>    
    </appender>
 
    <!-- 设置 log 级别 info -->
    <root level="info">
        <appender-ref ref="STDOUT" />
        <appender-ref ref="FILE" />
    </root>
 
 
 
</configuration>

使用

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
 
public class Test  {
 
    private Logger logger = LoggerFactory.getLogger(this.getClass());
 
    public void test()  {
        logger.info("----------------------Start ----------------------");
    }
}
