springboot2.0日志配置 logback的使用和logback.xml详解

[logback的使用和logback.xml详解][logback_logback.xml]写的非常详细。

只根据上面的我们会发现，日志要么输出到文件。要么输出到控制台不能有选择的输出满足我们的要求，这是需要看下面这个文章，

[多个xml路径，有选择的输出到文件][xml]。

这两篇文章结合，基本满足我们实际应用的需要。

为了使我们的日志更加利于观看，我们可以把日志做成html格式的，

完美。

在使用过程中发现需要每天生成一个，测试了好久总结到以下的xml

有一个logback-core.xml文件，配置上面已经讲了。

在application.yaml文件中，

1.  `logging:`
2.  `config: classpath:logback-core.xml`

在application.properties中添加，

logging.config=classpath:logback-core.xml
