    1. <included>

    使用自定义的logback.xml，则需要加上 相应的转换器类：

    1. <substitutionProperty name="log.pattern" value="%clr(%d{yyyy-MM-dd HH:mm:ss.SSS}){faint} %clr(%5p) %clr(---){faint} %clr(%-80.80logger{79}){cyan} %clr(:){faint} %m%n%wEx"/>
    3. <conversionRule conversionWord="clr" converterClass="org.springframework.boot.logging.logback.ColorConverter"/>
    4. <conversionRule conversionWord="wex" converterClass="org.springframework.boot.logging.logback.WhitespaceThrowableProxyConverter"/>
    5. <conversionRule conversionWord="wEx" converterClass="org.springframework.boot.logging.logback.ExtendedWhitespaceThrowableProxyConverter"/>
    7. <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">
    8.     <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
    9.         <pattern>${log.pattern}</pattern>
    10.     </encoder>
    11. </appender>
