Advantages:<\/p>\n

    \n
  1. Strong decoupling: The Handler pattern decouples the sender of the request from the receiver, so the sender doesn’t need to know how the request is being handled.<\/li>\n
  2. Strong scalability: it is easy to add new specific handlers to deal with new types of requests without modifying the existing code.<\/li>\n
  3. Simplify the code logic by breaking down complex processing into multiple Handlers, each responsible for handling its own part, making the code more clear.<\/li>\n<\/ol>\n

    Drawbacks:<\/p>\n

      \n
    1. Having too many handlers can lead to a decrease in performance: If requests need to go through multiple handlers for processing, it may result in a performance loss.<\/li>\n
    2. Chain call may be caused: If there is a dependency between Handlers, chain call situation may occur, which is difficult to maintain.<\/li>\n
    3. Complex interactions between Handlers may lead to increased code complexity and make it more difficult to comprehend.<\/li>\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
