摘要:而的日志文件在由指定。創建啟動類控制臺打印開源項目本地日志打印效果這里因為配置中將不同級別的日志設置了在不同文件中打印,這樣很大程度上方便項目出問題查找問題。
你是否因為項目出現問題,查找日志文件定位錯誤花費N多時間,是否為此苦不堪言,沒關系!現在通過這篇文章,將徹底解決你的煩惱,這篇文篇介紹,如何通過logback配置文件將日志進行分級打印,一個配置文件徹底搞定日志查找得煩惱。
準備工作環境:
windows jdk 8 maven 3.0 IDEA構建工程
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
#選擇哪一個環境的配置 #這里可以在每個環境配置redis,數據庫(mysql),消息(kafka)等相關的組件的配置 spring: profiles: active: dev #文檔塊區分為三個--- --- 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,這里是默認在項目根路徑下 path: log/spring-boot-log #文檔塊區分為三個--- --- 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,這里是默認在項目根路徑下 path: usr/spring-boot/log/spring-boot-log #文檔塊區分為三個--- --- 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,這里是默認在項目根路徑下 path: usr/spring-boot/log/spring-boot-log創建日志配置文件
在工程resources文件夾下新建文件夾log,并在該文件夾下創建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的屬性值一定要是當前工程的java代碼的完整目錄,因為mybatis打印的日志級別是debug級別的,因此需要配置debug級別日志掃描的目錄。
