Spring Boot(2.6版本)日志转换

1.去除springboot-starter的log4j依赖:

starter的log4j依赖:
<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-jdbc</artifactId>
			<exclusions>
				<exclusion>
					<groupId>org.springframework.boot</groupId>
					<artifactId>spring-boot-starter-logging</artifactId>
				</exclusion>
			</exclusions>
</dependency>
           

2.引入log4j2:

<dependency>
			<groupId>org.springframework.boot</groupId>
			<artifactId>spring-boot-starter-log4j2</artifactId>
</dependency>

3.dubbo-springboot的依赖不需要去除log4j,在依赖树中只能看到接口层的slf4j,可以兼容log4j2,所以不需要更改:

<dependency>
			<groupId>com.alibaba.boot</groupId>
			<artifactId>dubbo-spring-boot-starter</artifactId>
</dependency>

           

4.更改配置信息:

<properties>
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
		<project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
		<java.version>1.8</java.version>
		<!-- 设置变量替换属性 -->
		<log4j2.level>debug</log4j2.level>
		<log4j2.root.path>/opt/appstack/apache-tomcat/logs/${project.name}</log4j2.root.path>
		<log4j2.error.path>/opt/appstack/apache-tomcat/logs/${project.name}-error</log4j2.error.path>
		<log4j2.package.path>/opt/appstack/apache-tomcat/logs/${project.name}-kk</log4j2.package.path>
	 
</properties>
           

5.在resources目录下新建log4j2-spring.xml

<?xml version="1.0" encoding="utf-8"?>
<configuration>
	<properties>
		<!-- 文件输出格式 -->
		<property name="PATTERN">log4j2|%d{yyyy-MM-dd  HH:mm:ss.SSS} | -%-5level [%thread] %c [%L] -| %msg%n</property>
	</properties>
 
	<appenders>
		<Console name="CONSOLE" target="system_out">
			<PatternLayout pattern="${PATTERN}" />
		</Console>
	</appenders>
	
	<loggers>
		<logger name="com.roncoo.education" level="debug" />
		<root level="info">
			<appenderref ref="CONSOLE" />
		</root>
	</loggers>
 
</configuration>
           

6:完整配置:
