A dynamic management method for a menu, comprising: collecting, when a function of an independently deployed microservice changes, a menu change message generated when the function changes, wherein the menu change message comprises a menu registration message and a menu uninstallation message; receiving the menu change message through message-oriented middleware deployed in a cluster mode, and broadcasting the menu change message; monitoring and parsing, at a portal unit, the menu change message to obtain a menu display file; and sending the menu display file to a corresponding display interface, and updating a menu displayed on the display interface, wherein before collecting the menu change message generated when the function changes, the method further comprises: saving menu information corresponding to respective microservices separately by using a distributed database or a distributed cache to generate a menu set; and wherein after monitoring and parsing, at a portal unit, the menu change message to obtain a menu display file, the method further comprises: acquiring, when the portal unit needs to provide a set of some functions, menu identification information corresponding to a menu displayed by the portal unit and the menu set, and obtaining an intersection of the menu identification information and the menu set as a set of merged menus; and organizing the set of merged menus into a menu tree structure, and converting menu tree nodes according to a display format to generate the menu display file. collecting, when a function of an independently deployed microservice changes, a menu change message generated when the function changes, wherein the menu change message comprises a menu registration message and a menu uninstallation message; receiving the menu change message through message-oriented middleware deployed in a cluster mode, and broadcasting the menu change message; monitoring and parsing, at a portal unit, the menu change message to obtain a menu display file; and sending the menu display file to a corresponding display interface, and updating a menu displayed on the display interface, wherein before collecting the menu change message generated when the function changes, the method further comprises: saving menu information corresponding to respective microservices separately by using a distributed database or a distributed cache to generate a menu set; and wherein after monitoring and parsing, at a portal unit, the menu change message to obtain a menu display file, the method further comprises: acquiring, when the portal unit needs to provide a set of some functions, menu identification information corresponding to a menu displayed by the portal unit and the menu set, and obtaining an intersection of the menu identification information and the menu set as a set of merged menus; and organizing the set of merged menus into a menu tree structure, and converting menu tree nodes according to a display format to generate the menu display file. saving menu information corresponding to respective microservices separately by using a distributed database or a distributed cache to generate a menu set; and wherein after monitoring and parsing, at a portal unit, the menu change message to obtain a menu display file, the method further comprises: acquiring, when the portal unit needs to provide a set of some functions, menu identification information corresponding to a menu displayed by the portal unit and the menu set, and obtaining an intersection of the menu identification information and the menu set as a set of merged menus; and organizing the set of merged menus into a menu tree structure, and converting menu tree nodes according to a display format to generate the menu display file. acquiring, when the portal unit needs to provide a set of some functions, menu identification information corresponding to a menu displayed by the portal unit and the menu set, and obtaining an intersection of the menu identification information and the menu set as a set of merged menus; and organizing the set of merged menus into a menu tree structure, and converting menu tree nodes according to a display format to generate the menu display file.
