SpringBoot's logging is based on the application multi-environment configuration file configuration log output to a file (not spring-logback.xml)

General situation: Log files are divided into folders according to yyyy-MM-dd, %i cuts files according to the size of a single log file and names them with an index.

1. Development environment (dev): only output to the console, not to the file, and the log level is INFO.
2. Test environment (test): output to the console and output to a file, the log level is INFO, and the log content can be cleared when restarting (convenient for debugging).
3. Production environment (prod): do not output to the console, only output to the file, the log level is ERROE (only error logs are recorded), and it is forbidden to clear the log when restarting (to prevent other people's error logs from being cleared, causing others to be unable to locate the problem) .

pom.xml adds environment configuration

	<!-- 环境配置 -->
    <profiles>
        <profile>
            <id>dev</id>
            <properties>

            </properties>
            <activation>
                <!--  设为默认开启 -->
                <activeByDefault>true</activeByDefault>
            </activation>
