一、简介

支持日志框架：Java Util Logging, Log4J2 and Logback，默认是使用logback

logback配置方式

spring boot默认会加载classpath:logback-spring.xml或者classpath:logback-spring.groovy

使用自定义配置文件，配置方式为：

logging.config=classpath:logback-roncoo.xml

注意：不要使用logback这个来命名，否则spring boot将不能完全实例化

logback-spring.xml：

<?xml version="1.0" encoding="UTF-8"?>
<configuration>

    <!-- 文件输出格式 -->
    <property name="PATTERN" value="http://www.mamicode.com/%-12(%d{yyyy-MM-dd HH:mm:ss.SSS}) |-%-5level [%thread] %c [%L] -| %msg%n" />
    <!-- test文件路径 -->
    <property name="TEST_FILE_PATH" value="G:/workspace/logs_workspace/roncoo/logs" />
    <!-- pro文件路径 -->
    <property name="PRO_FILE_PATH" value="http://www.mamicode.com/opt/roncoo/logs" />

        <root level="info">
