The invention relates to a method for docking an external
system in a supply
chain system, and the method comprises the steps: designing a unified external
system interaction framework based on message driving: defining a BaseHandler
base class, and integrating getParams
parameter analysis, sendRequest request sending and handleResponse response
processing logic; external
system configuration is stored through the
relational database; the business system generates a standardized message and pushes the standardized message to a corresponding MQ theme; and monitoring Topic by the unified consumption service, querying configuration of an enabled state according to the actionCode in the message, dynamically instantiating and specifying a processor subclass, and sequentially executing
parameter analysis, external request calling and response
processing flows, so as to realize decoupling and dynamic expansion capabilities of
business logic and external interaction. According to the method, through unified management configuration and logic, the code repetition rate is reduced, and the maintenance cost is reduced; dynamic configuration supports a
quick start-stop docking function and adapts to business change requirements; the standardized process enables the code structure to be clear, and team cooperation and subsequent expansion are facilitated.
