logback.xml 报警告

As will be demonstrated over and over, the syntax of logback configuration files is extremely flexible. As such, it is not possible to specify the allowed syntax with a DTD file or an XML schema. 

可以添加下面这个去除警告

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>

 

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
<configuration debug="true">

  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <!-- encoders are assigned the type
         ch.qos.logback.classic.encoder.PatternLayoutEncoder by default -->
    <encoder>
      <pattern>%-4relative [%thread] %-5level %logger{35} - %msg %n</pattern>
    </encoder>
  </appender>

  <root level="TRACE">
    <appender-ref ref="STDOUT" />
  </root>
</configuration>
