What is the difference between the agent pattern and the decorator pattern in java? aiming at this problem, this article introduces the corresponding analysis and solution in detail, hoping to help more partners who want to solve this problem to find a more simple and feasible method.

The proxy pattern looks very similar to the decorator pattern, both implement the interface implemented by the underlying object, and both hold object references to the proxied / decorated in their own objects.

Definition of the decorator pattern:

Dynamically attach responsibility to the decorated object to extend the function of the object. Is more flexible than inheritance. A typical design such as Java IO is a typical application of the decorator pattern.

Definition of proxy pattern:

Delegate to other objects to control access to the proxied object. Spring generates proxy classes for business logic layer methods, mainly for some transaction control, and so on.

The difference between the two:

The responsibility of decoration is to extend the function, while the agent mainly controls access.

The answer to the question about what is the difference between the agent mode and the decorator mode in java is shared here. I hope the above content can be of some help to everyone.
