java - 如何使用 Spring Boot/slf4j 在日志文件的名称中包含日期？

Question

和Setting a log file name to include current date in Log4j是同一个问题，但是如何应用到slf4j自带的Spring Boot中呢？

应用程序属性

spring.application.name=keywords
logging.file=logs/${spring.application.name}.log

如所述here

Spring Boot has a LoggingSystem abstraction that attempts to configure logging based on the content of the classpath.

使用它

The simplest way to do that is through the starter poms which all depend on spring-boot-starter-logging. For a web application you only need spring-boot-starter-web since it depends transitively on the logging starter.

因为 Logback 是可用的，所以它是首选。

To configure the more fine-grained settings of a logging system you need to use the native configuration format supported by the LoggingSystem in question. By default Spring Boot picks up the native configuration from its default location for the system (e.g. classpath:logback.xml for Logback), but you can set the location of the config file using the "logging.config" property.

如果默认设置对您来说没问题，只需创建 logback.xml 并添加相应的文件附加程序，例如

<appender name="rollingFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
  <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
    <FileNamePattern>LogFile.%d{yyyy-MM-dd}.log</FileNamePattern>
    <MaxHistory>30</MaxHistory>
  </rollingPolicy>
  <encoder>
    <pattern>%d %-5level [%thread] %logger{0}: %msg%n</pattern>
  </encoder>
</appender>
