Difference between Application runner and command line runner in Spring Boot

on channel: Java Boot Programmer

In Spring Boot, both CommandLineRunner and ApplicationRunner are interfaces that allow you to execute code after the Spring application has started. However, they differ in how they handle command-line arguments:

CommandLineRunner:
Simpler interface.
Provides access to the command-line arguments as a simple string array.
Suitable for basic use cases where you need to directly access the raw arguments.
-------------------------------------------------------------------------------------------------------------------------------------
ApplicationRunner:
More advanced interface.
Provides access to the command-line arguments through the ApplicationArguments object, which offers more structured access and parsing capabilities.
Useful when you need to handle complex arguments or options.
