I wish to use different colours to distinguish between INFO, DEBUG and TRACE in Spring Ansi Coloured Logs, as they are currently all set to Green (see table below) From the docs here https://docs.s. Overview Checking log without color is hard. Enable color for your log messages would make things a bit easier.

I'll show you how to do that with logback in spring. Configuration First of all, you need to create a file name logback-spring.xml under your resource folder. Here is my file.

That's because every starter, like our spring-boot-starter-web, depends on spring-boot-starter-logging, which already pulls in spring-jcl for us. 3.1. Default Logback Logging When using starters, Logback is used for logging by default.

Spring Boot preconfigures it with patterns and ANSI colors to make the standard output more readable. Learn about configuring and managing logging in Spring Boot applications, including log levels, patterns, and integration with popular logging frameworks. Spring boot supports color coding of logging output displayed on the console.

This enables us to quickly identify any errors or warnings logged by spring boot system. Learn the default spring boot logging and configuring custom log levels, file appenders and colored logs via application.yaml file. Logback in the other hand is a popular logging framework for Java-based applications, and it provides colorful logging through the use of encoders.

Colored logging can make it easier to identify. The log format and ANSI colors are configured By Spring Boot beforehand to make the logging more readable. The following components are present in the log output: Date of logging Time with millisecond precision Log level shows INFO, WARN and ERROR by default Process ID.

Why It's Useful When spring.output.ansi.enabled is set to true (which is often the default or recommended setting), your Spring Boot application's logs and other console output become much more readable and visually distinct. For example, you might see.
