the same result, that is, the service is idempotent. Service idempotent is sometimes natural, such as setting the user's gender as a male, regardless of how many times it is set, the result is the same, but for operations such as transfer transactions, the problem becomes complex and requires information such as transaction numbers. For service invocation validation, only valid actions can continue. Study Note 6: The core Principles and
