1、POM文件增加Log4j2

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

2、bootstrap.yml配置Log4j2

logging:
      config: classpath:log4j2.xml

3、配置log4j2.xml

<?xml version="1.0" encoding="UTF-8"?>
    
    <Configuration status="OFF">
        <Appenders>
            
            <Console name="Console" target="SYSTEM_OUT" follow="true">
                <PatternLayout>
                    <pattern>[%-5p] %d %c - %m%n</pattern>
                </PatternLayout>
            </Console>
            
            <File name="File" fileName="app.log"  append="false">
            	<PatternLayout>
                    <pattern>%d{yyyy-MM-dd HH:mm:ss.SSS} %-5level %class{36} %L %M - %msg%xEx%n</pattern>
                </PatternLayout>
            </File>
        </Appenders>
        <Loggers>
            
            <Root level="INFO">
                <AppenderRef ref="Console" />
                
                <AppenderRef ref="File" />
            </Root>
            <Logger name="org.springframework" level="INFO" />
            <Logger name="zaxxer.hikari" level="INFO" />
            <Logger name="org.thymeleaf" level="INFO" />
            
            <Logger name="com.ibatis" level="INFO"/>
            <Logger name="java.sql" level="INFO" />
        </Loggers>
    </Configuration>

4、代码中使用Log4j2

import org.apache.logging.log4j.LogManager;
    import org.apache.logging.log4j.Logger;
    
    private Logger logger =  LogManager.getLogger(this.getClass());
    
    logger.info("日志");

安装以上配置使用logger，避免包冲突及无法输出信息的问题。
