Answer
It enforces immutability and ensures dependencies are set.
Constructor injection in Spring is beneficial as it promotes immutability and ensures all dependencies are initialized at object creation. This reduces the risk of null dependencies and makes the code more testable. For example, injecting an OrderRepository into OrderService via constructor ensures the service always has its necessary dependency ready.
