I am trying to create custom layout in Logback, using the link,
Creating a custom layout in Logback
and i am successful in creating log file.
The problem is when I apply "pattern" tag in encoder tag of logback.xml like this,
<appender name="appLogFileAppender" class="ch.qos.logback.core.rolling.RollingFileAppender">
<rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
<fileNamePattern>C:/tmp.log</fileNamePattern>
</rollingPolicy>
**<encoder class="ch.qos.logback.core.encoder.LayoutWrappingEncoder">
<pattern> %d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n </pattern>
<layout class="com.dces.util.LoggingConsoleLayout" />
</encoder>
</appender>**
it is not applied on log file, which is created, and I am getting content without date&time AS BELOW.
-- [ERROR]main.java.com.srccodes.log.LogbackHello - Welcome to the HelloWorld example of Logback. -- [ERROR]main.java.com.srccodes.log.LogbackHello - Dummy error message.
Actually if I remove class="ch.qos.logback.core.encoder.LayoutWrappingEncoder" in encoder tag ,pattern is working, but then my custom layout is not working.
I want to apply pattern tag as well as custom layout tag on encoder tag.Is it is possible?
Can anyone help me in this?
As you can see from your link, the default encoder is PatternLayoutEncoder which supports patterns. If you really want to have both functionalities, you could try subclassing LayoutWrappingEncoder and add the pattern functionality to it yourself (or maybe with some clever composition).
