Hello Guys 

I want to create the logstash encoder you see in xml with Java code.  But there is no method to set the pattern.  Which method should I do?

<appender name="STASH" class="ch.qos.logback.core.rolling.RollingFileAppender">
    <file>logback/uptLog.log</file>
    <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">
        <fileNamePattern>logback/uptLog.%d{yyyy-MM-dd}.log</fileNamePattern>
    </rollingPolicy>
    <encoder class="net.logstash.logback.encoder.LogstashEncoder">
        <charset>UTF-8</charset>
        <pattern>
            %d{yyyy-MM-dd HH:mm:ss.SSS} [%t] %-5level %logger{36} - %X{requestId} %msg%n%exception{full}
        </pattern>
    </encoder>
</appender>

net.logstash.logback.encoder.LogstashEncoder logstashEncoder = new LogstashEncoder();
logstashEncoder.setContext(loggerContext);
logstashEncoder.start();
