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.");
    }
}
