This is very simple Logback appender to see the logs on your Slack account also.

How to setup

Copy com.wpic.logback.SlackAppender.java to your source directory

Add SlackAppender configuration to logback.xml file

<?xml version="1.0" encoding="UTF-8" ?>
	<configuration>
	
	<!-- Setup appender -->
	<appender name="SLACK" class="com.wpic.logback.SlackAppender">
		<!-- API token - Get it from here: https://api.slack.com/ -->
		<token>1111111111-1111111-11111111-111111111</token>
		<!-- Channel that you want to post - default is #general -->
		<channel>#api-test</channel>
		<!-- Bot's username - default is 'bot' -->
		<username>Error Notification!</username>
		<!-- Bot's icon that does not contain a colon(:)-->
		<iconEmoji>persevere</iconEmoji>
		<!-- Formatting -->
		<layout class="ch.qos.logback.classic.PatternLayout">
			<pattern>%-4relative [%thread] %-5level %class - %msg%n</pattern>
		</layout>
	</appender>

	<root>
		<level value="ALL" />
		<appender-ref ref="SLACK" />
