How do I configure Logback using Groovy?

How do I configure Logback using Groovy?

You can configure Logback using a Groovy script by creating a logback.groovy file. This file allows you to define your logging configuration in a more dynamic way.

What are some common settings I can include in the Groovy configuration?

Common settings include defining appenders, loggers, and setting the logging level. For example, you can set up a console appender and specify the log level for different packages.

Can you show me an example of a simple Groovy configuration?

Sure! Here's a simple example:

import ch.qos.logback.classic.Level
import ch.qos.logback.core.ConsoleAppender
import ch.qos.logback.core.rolling.RollingFileAppender
import ch.qos.logback.core.rolling.TimeBasedRollingPolicy

appender('CONSOLE', ConsoleAppender) {
    encoder(PatternLayoutEncoder) {
        pattern = '%d{yyyy-MM-dd HH:mm:ss} %-5level %logger{36} - %msg%n'
    }
}

logger('com.example', Level.DEBUG)
root(Level.INFO, ['CONSOLE'])

How can I change the log level for a specific package?

You can change the log level for a specific package by adding a logger definition in your Groovy configuration. For example:

logger('com.example.service', Level.DEBUG)
``` This sets the log level to DEBUG for the `com.example.service` package.
