logback日志持久化

1、问题描述

        使用logback持久化记录日志。

2、我的代码

        logback是Springboot框架里自带的，所以只要引入“spring-boot-starter”就行了。无需额外引入logback依赖。

        pom.xml

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>org.example</groupId><artifactId>TestLogBack</artifactId><version>1.0-SNAPSHOT</version><properties><maven.compiler.source>8</maven.compiler.source><maven.compiler.target>8</maven.compiler.target><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><springframework.version>2.2.1.RELEASE</springframework.version></properties><dependencies><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-web</artifactId><version>${springframework.version}</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter</artifactId><version>${springframework.version}</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-test</artifactId><version>${springframework.version}</version></dependency><dependency><groupId>org.springframework.boot</groupId><artifactId>spring-boot-starter-aop</artifactId><version>${springframework.version}</version></dependency><dependency><groupId>org.projectlombok</groupId><artifactId>lombok</artifactId><version>1.18.20</version><scope>compile</scope></dependency></dependencies>
</project>

        

          logback-spring.xml

（带“-spirng”的配置文件则无需在application.yml里面在配置logging:config)

<?xml version="1.0" encoding="UTF-8"?>
<configuration><include resource="org/springframework/boot/logging/logback/defaults.xml" /><include resource="org/springframework/boot/logging/logback/console-appender.xml" /><!-- 开启后可以通过jmx动态控制日志级别(springboot Admin的功能) --><!--<jmxConfigurator/>--><springProperty scope="context" name="log.path" source="logging.path" defaultValue="./logs"/><appender name="common-all" class="ch.qos.logback.core.rolling.RollingFileAppender">

</configuration>

        
         TestLogbackController.java

package com.mytest.controller;import lombok.extern.slf4j.Slf4j;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;/*** @author: Wulc* @time: 2024/5/10 21:54* @description:*/
@RestController
@RequestMapping("/test")
@Slf4j
public class TestLogbackController {//private Logger logger = LoggerFactory.getLogger(getClass());@GetMapping("/printLog")public String printLog(int i) {//logger.info("打印一条日志");log.info("打印一条日志");int k = 10 / i;return "打印了日志";}
}

3、效果

4、总结

        写这篇文章，主要是记录一下logback-spring.xml的配置内容。
