springboot默认的日志文件是不会自动按天分割的，所以生产环境的日志文件越来越大，很不利于排错。查了很多资料最终配置如下，可以完美按天按错误等级分割日志文件，配置如下。

由于springboot采用约定优先于配置的方式，日志文件也是，SpringBoot项目中在官方文档中（[https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html][https_docs.spring.io_spring-boot_docs_current_reference_html_boot-features-logging.html]）说明，默认已经依赖了一些日志框架。而其中推荐使用的就是Logback，说明一下，SpringBoot已经依赖了Logback所以不需要手动添加依赖。

首先不同环境下的logback配置肯定是不一样的，所以我的解决办法是：

项目中的application.properties已经通过spring.profiles.active来分割成不同环境下使用不同的properties配置，比如application-dev.properties(开发环境)，application-uat.properties(测试环境)，application-prod.properties（生产环境）,再加上application.properties（这个文件可能只包含spring.profiles.active就够了，真正的配置可能都在带-的文件里，因为springboot默认会加载它，然后通过它来指定使用哪个文件） 共有4个properties 文件，然后在application.properties 通过spring.profiles.active指定要使用的真正的properties

ok 上面是简单的聊了一下application.properties配置的问题，正戏来了

接下来就要创建出来 logback-spring-dev.xml，logback-spring-uat.xml，logback-spring-prod.xml三个文件，然后在每个对应环境的properties通过 logging.config 来指定logback 的xml文件

logging.config=classpath:logback-spring-prod.xml

至于logback的xml文件内容如下：

logback-spring-dev.xml 开发环境下，不需要输出到文件，只需要打印在控制台就行了

然后是 logback-spring-prod.xml 和logback-spring-uat.xml，uat环境与prod的只是文件位置不同所以只贴一份了，改下路径就行了，并且生产和测试是不需要控制台输出的 不然catalina.out文件就要爆炸了

    		<appender-ref ref="TRACE" />

    </configuration>

最后达到的效果是按大小日期生成日志文件，超过设定大小就会重新生成新文件，由0开始累积。
