demo:

spring boot log存在兩種形式

1.使用默認(rèn)的logback

    直接在application.properties中設(shè)置

        ## spring boot log4j
	logging.level.org.springframework.web=INFO
	logging.level.guru.springframework.blogs.controllers=INFO
	logging.level.org.hibernate=ERROR
	logging.file=logs/spring-boot-logging.log

2.使用log4j

pom.xml

	<parent>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-parent</artifactId>
		<version>1.5.9.RELEASE</version>
	</parent>

	<properties>
    	<java.version>1.8</java.version>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>

	<dependencies>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-web</artifactId>
			<exclusions>
                <exclusion>  
                    <groupId>org.springframework.boot</groupId>  
                    <artifactId>spring-boot-starter-logging</artifactId>  
                </exclusion>  
			</exclusions>
		</dependency>
		<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-log4j2</artifactId>
		</dependency>
	</dependencies>

application.properties

	logging.config=classpath:log4j2.xml

log4j2.xml

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