摘要:而的日志文件在由指定。创建启动类控制台打印开源项目本地日志打印效果这里因为配置中将不同级别的日志设置了在不同文件中打印,这样很大程度上方便项目出问题查找问题。
你是否因为项目出现问题,查找日志文件定位错误花费N多时间,是否为此苦不堪言,没关系!现在通过这篇文章,将彻底解决你的烦恼,这篇文篇介绍,如何通过logback配置文件将日志进行分级打印,一个配置文件彻底搞定日志查找得烦恼。
准备工作环境:
windows jdk 8 maven 3.0 IDEA构建工程
修改YML配置4.0.0 cn.zhangbox spring-boot-study 1.0-SNAPSHOT cn.zhangbox spring-boot-log 0.0.1-SNAPSHOT jar spring-boot-logging Demo project for Spring Boot UTF-8 UTF-8 1.8 org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-maven-plugin
#选择哪一个环境的配置 #这里可以在每个环境配置redis,数据库(mysql),消息(kafka)等相关的组件的配置 spring: profiles: active: dev #文档块区分为三个--- --- server: port: 8081 spring: profiles: dev #日志 logging: #日志配置文件位置 config: classpath:log/logback.xml #日志打印位置,这里是默认在项目根路径下 path: log/spring-boot-log #文档块区分为三个--- --- server: port: 8082 spring: profiles: test #日志 logging: #日志配置文件位置 config: classpath:log/logback.xml #日志打印位置,这里是默认在项目根路径下 path: usr/spring-boot/log/spring-boot-log #文档块区分为三个--- --- server: port: 8083 spring: profiles: prod #日志 logging: #日志配置文件位置 config: classpath:log/logback.xml #日志打印位置,这里是默认在项目根路径下 path: usr/spring-boot/log/spring-boot-log创建日志配置文件
在工程resources文件夹下新建文件夹log,并在该文件夹下创建logback.xml文件,加入以下配置:
${CONSOLE_LOG_PATTERN} UTF-8 debug ${LOG_PATH}/log_debug.log %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n UTF-8 ${LOG_PATH}/debug/log-debug-%d{yyyy-MM-dd}.%i.log 500MB 30 debug ACCEPT DENY ${LOG_PATH}/log_info.log %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n UTF-8 ${LOG_PATH}/info/log-info-%d{yyyy-MM-dd}.%i.log 500MB 30 info ACCEPT DENY ${LOG_PATH}/log_warn.log %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n UTF-8 ${LOG_PATH}/warn/log-warn-%d{yyyy-MM-dd}.%i.log 500MB 30 warn ACCEPT DENY ${LOG_PATH}/log_error.log %d{yyyy-MM-dd HH:mm:ss.SSS} [%thread] %-5level %logger{50} - %msg%n UTF-8 ${LOG_PATH}/error/log-error-%d{yyyy-MM-dd}.%i.log 500MB 30 error ACCEPT DENY
注意:loback配置文件中
name的属性值一定要是当前工程的java代码的完整目录,因为mybatis打印的日志级别是debug级别的,因此需要配置debug级别日志扫描的目录。
创建启动类@SpringBootApplication public class SpringBootConfigApplication { public static void main(String[] args) { SpringApplication.run(SpringBootConfigApplication.class, args); } }控制台打印

摘要:本文要来分享给大家程序员最常用的日志框架组件。没有基础的同学也不要着急,这套教程覆盖了目前所有的日志框架,只要你学,就一定用得到,先收藏,以备不时之需。 作为一名Java程序员,我们开发了很多Java应用程序,包括桌面应用、WEB应用以及移动应用。然而日志系统是一个成熟Java应用所必不可少的。在开发和调试阶段,日志可以帮...
摘要:默认情况下将级别的日志输出到控制台中,不会写到日志文件,且不能进行复杂配置。节点用于定义变量,方便使用。 showImg(https://raw.githubusercontent.com/FleyX/files/master/blogImg/20190320135049.png); 前言 java web 下有好几种日志框架,比如:logback,log4j,log4j2(slj...
