Simplified Chain of responsibility design pattern demo using spring boot 4.
I use this pattern to the system I refactored. It will handle the request in a chain. The chain is constructed by three handlers. Each handler processes the request AND passes it to the next handler, and will stop if the next handler is null.
This application will call a handler service to start the chain with a fake request every 10 seconds.
Output example:
Handler 1 handled request_1770015006205
Handler 2 handled request_1770015006205
Handler 3 handled request_1770015006205
Handler 1 handled request_1770015016206
Handler 2 handled request_1770015016206
Handler 3 handled request_1770015016206
