  WHAT Observability is a concept that refers to the ability to gain insights into the behavior and performance of complex systems. In the context of software engineering, observability involves the collection, analysis, and visualization of data from software applications, infrastructure, and other components of a system. In the animal kingdom, observability plays a critical role in survival, allowing animals to monitor their surroundings, detect threats, and find food. Dolphins use echolocation to observe their surroundings. They emit high-frequency sounds that bounce off objects, allowing them to create a 3D map of their environment.

There is a way in Spring 3.1 to auto populate a typed List which is very handy when you want to push a bit the decoupling and the cleaning in your code. To show you how it works, I will implement a simple chain of responsibility that will take care of printing some greetings for a passed User. Let start from the (only) domain class we have, the User: package in.softcaretech.springchain; public class User { private final String name; private final char gender; public User(String name, char gender) { super(); this.name = name; this.gender = gender; } public String getName() { return name; } public char getGender() { return gender; } } Then we create an interface that defines the type for our command objects to be used in our chain: package in.softcaretech.springchain; public interface Printer { void print(User user); } This is the generic class (the template) for a Printer implementation. The  org.springframework.core.Ordered  is used to tell the AnnotationAwareOrderCo...
