springboot2.0整合logback

一、开发环境

开发环境

• JDK 8

• Spring Boot 2.0. 9 RELEASE

• Maven

• Windows 10

• IDEA 20 20 . 3

Spring Boot默认集成了Logback，可以开箱即用， 不需要再次引入 spring-boot-starter-logging 依赖 ， 因为 Spring Boot启动 时加载 spring-boot-starter ，而 spring-boot-starter 包含了 spring-boot-starter-logging，所以Spring Boot就默认集成了Logback 。

2、 配置信息

在resource下创建logback-spring.xml文件

然后在yml中配置

logging.config=classpath:log/logback-spring.xml

logging.path=D:/nmyslog/nmys

最后将下面的代码复制到logback-spring.xml里。

<?xml version="1.0" encoding="UTF-8"?><!-- 日志级别从低到高分为TRACE < DEBUG < INFO < WARN < ERROR < FATAL，如果设置为WARN，则低于WARN的信息都不会输出 --><!-- scan:当此属性设置为true时，配置文件如果发生改变，将会被重新加载，默认值为true --><!-- scanPeriod:设置监测配置文件是否有修改的时间间隔，如果没有给出时间单位，默认单位是毫秒。当scan为true时，此属性生效。默认的时间间隔为1分钟。 --><!-- debug:当此属性设置为true时，将打印出logback内部日志信息，实时查看logback运行状态。默认值为false。 --> < configuration scan =" true " scanPeriod =" 10 seconds ">

<!--<include resource="org/springframework/boot/logging/logback/base.xml"

/> -->
