Logback logback.xml Console Appender Tanımlama

Giriş

class olarak "ch.qos.logback.core.ConsoleAppender" kullanmak gerekiyor. Daha sonra da bir encoder tanımlamak lazım

encoder

pattern içinde log formatı belirtilir.

layout belirtilir ama ne olduğunu tam bilmiyorum

Örnek

Şöyle yaparız.

<configuration>
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
      <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
    </encoder>
  </appender>
  ...  
</configuration>

Örnek

Şöyle yaparız.

<configuration>
  <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
    <encoder>
        <layout class="com.touchcorp.touchpoint.utils.MaskingPatternLayout">
          <pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
        </layout>
    </encoder>
  </appender>
  ...
</configuration>

Şöyle yaparız
