slf4j logger.info how to NOT print out the package information

Question

let say I have this code:

public static final Logger LOGGER = LoggerFactory.getLogger(MethodHandles.lookup().lookupClass());
public static void main(String[] args) {
        LOGGER.info("Hi !");
    }

But the output in console is this:

[main] INFO com.sirma.itt.javacourse.logger.example - Hi !

I would like to customize or edit the output. I do not need this "package information". So it would looks like this:

[main] - Hi !

or just:

Hi !

Answer 1

So what I did: 1. In parent pom I switched the defauld slf4j dependency with:

 <dependency>
    <groupId>ch.qos.logback</groupId>
    <artifactId>logback-classic</artifactId>
    <version>1.0.13</version>
</dependency>

2. In src/main/resources I created a file with name logback.xml and enter these settings:

    <configuration>
    <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>[%thread] %-5level - %msg%n</pattern>
        </encoder>
    </appender>

    <logger name="deng" level="DEBUG" />

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