JAVA项目中引用Logback的方法

一、简介

　　本文主要讲JAVA项目中引入Logback的方法。

　　

二、解决

　　1、引入依赖。

        <!--Begin LogBack Log-->

        <!-- https://mvnrepository.com/artifact/ch.qos.logback/logback-classic -->

        <dependency>

            <groupId>ch.qos.logback</groupId>

            <artifactId>logback-classic</artifactId>

            <version>1.2.3</version>

        </dependency>

        <!-- https://mvnrepository.com/artifact/org.slf4j/slf4j-api -->

        <dependency>

            <groupId>org.slf4j</groupId>

            <artifactId>slf4j-api</artifactId>

            <version>1.7.25</version>

        </dependency>

        <!--End LogBack Log-->

　　2、添加配置

　　在resources文件夹，或者类目录下中，新建logback.xml，内容如下：

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

<!-- For assistance related to logback-translator or configuration  -->

<!-- files in general, please contact the logback user mailing list -->

<!-- at http://www.qos.ch/mailman/listinfo/logback-user             -->

<!--                                                                -->

<!-- For professional support please see                            -->

<!--    http://www.qos.ch/shop/products/professionalSupport         -->

<!--                                                                -->

<configuration>

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

        <encoder>

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

        </encoder>

    </appender>

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

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

            <!-- Daily rollover -->

            <fileNamePattern>log/generator.%d{yyyy-MM-dd}.log</fileNamePattern>

            <!-- Keep 7 days' worth of history -->

            <maxHistory>7</maxHistory>

        </rollingPolicy>

        <encoder>

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

        </encoder>

    </appender>

    <!-- Configure so that it outputs to both console and log file -->

    <root level="INFO">

        <appender-ref ref="FILE" />

        <appender-ref ref="STDOUT" />

    </root>

</configuration>

　　3、编写调用代码 ：

import org.slf4j.Logger;

import org.slf4j.LoggerFactory;

public class ApplicationMain {

    static Logger log = LoggerFactory.getLogger(ApplicationMain.class);

    public static void main(String[] args) {

        log.info("hello world.");

    }

}
