How to include date in log file's name with Spring Boot / slf4j?
提问by sinedsem
It is the same question as Setting a log file name to include current date in Log4j, but how to apply it to Spring Boot, which comes with slf4j?
这与设置日志文件名以在 Log4j 中包含当前日期相同，但如何将其应用于 slf4j 附带的 Spring Boot？
application.properties
应用程序属性
spring.application.name=keywords
logging.file=logs/${spring.application.name}.log

As described here
如上所述这里
Spring Boot has a LoggingSystem abstraction that attempts to configure logging based on the content of the classpath.
Spring Boot 有一个 LoggingSystem 抽象，它尝试根据类路径的内容配置日志记录。
To employ it
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 needspring-boot-starter-websince it depends transitively on the logging starter.
最简单的方法是通过所有依赖于
spring-boot-starter-logging. 对于 Web 应用程序，您只需要spring-boot-starter-web它，因为它传递地依赖于日志记录启动器。
Because Logback is available it is the first choice.
因为 Logback 可用，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.
要配置日志系统的更细粒度的设置，您需要使用相关 LoggingSystem 支持的本机配置格式。默认情况下，Spring Boot 从系统的默认位置获取本机配置（例如，用于 Logback 的 classpath:logback.xml），但您可以使用“logging.config”属性设置配置文件的位置。
If default is ok for you just create logback.xmland add corresponding file appender, e.g.
如果默认值对您来说没问题，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>
