What is Logger
In Spring Boot, a logger is a utility that is used to record or log information about the application's execution. It helps developers monitor and troubleshoot the application by capturing various types of messages or events, such as errors, warnings, and informational messages. Logging is an essential component of application development for debugging and monitoring purposes. Spring Boot uses various logging frameworks like Logback, Log4j, and Java Util Logging, and provides a common abstraction layer to configure and use them in a standardized way.

Developers can use loggers to write messages to different log levels
(e.g., DEBUG, INFO, WARN, ERROR) and configure the log output destination (e.g., console, file, remote server) to meet their specific needs. This helps in diagnosing issues, tracking the flow of the application, and ensuring it behaves as expected.
