Detailed Description
Exemplary embodiments of the present invention will now be described with reference to the accompanying drawings, in which various details of the embodiments of the present invention are included to facilitate understanding, and are to be considered merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic diagram of main flow of a service processing method according to a first embodiment of the present invention, and as shown in fig. 1, the service processing method includes:
step S101, receiving a service data request and acquiring a corresponding flow code.
In an embodiment, the corresponding service processing flows are uniquely defined by one flow code flowCode, that is, one service processing flow corresponds to one flow code flowCode, and the service data request corresponds to the corresponding service processing flow.
Step S102, calling a data stream processing engine through an external unified calling interface, and further obtaining a corresponding executor according to the flow code.
In some embodiments, as shown in fig. 2, a schematic diagram of a core processing class according to an embodiment of the present invention is shown. The data stream processing engine is called through a calling interface provided by the resourceHandlerExecutor class.
Preferably, an interface can be set for each chain node, and a resource handler abstract service processing node interface (i.e. a chain node interface) is realized through an abstract class of abstract resource hander, so that each service flow includes a plurality of realization instances of abstract resource hander. For example: freezeMoney, freezeGoods fund freeze, cargo freeze two example implementation classes inherit the abstract class of Abstract ResourceHandler.
Further, the validRequest method in the Abstract ResourceHandler abstract class, default true indicates that the current node is executed, and if a certain condition needs to be met, the current node needs to be executed, and the method needs to be rewritten. That is, a call condition may be set for each chain node by the validRequest method in the Abstract ResourceHandler abstract class. In addition, the failback method in the abstract class of Abstract resource Handler defaulttrue is used for realizing the rollback of the current chain node.
Preferably, for each chain node, this is implemented by a minimum event handling unit resource handler class. The method is realized for specific implementation classes by a doHandle method of a minimum event processing unit resource handler class, and subtasks of the current node can be processed. The handle method of the resource handler class is a chain (process) execution scheduling method through a minimum event processing unit. Whether the current node needs to execute verification is determined by a validRequest method of a minimum event processing unit ResourceHandler class. The current node rollback is performed by the failback method of the minimum event handling unit resource handler class.
It should be noted that, before the service data request is processed according to the configuration flow of the executor, a configuration flow may be set for each flow code through an abstract resource handleconfiguration class. Each business process is configured separately, such as a billing process, a transfer process.
As a specific embodiment, as shown in fig. 3 and 4, a specific actuator is configured, including two business processes, namely "general replenishment execution process" and "urgent replenishment execution process". Taking "general replenishment" as an example, the configuration is shown, the general replenishment flow configuration service node defines a flow code flowCode as 20423999 by a flowType method, and the handlerConfigname method sets a flow name as "general replenishment". The general replenishment service chain node is configured through a handler method, and the chain node comprises front verification, parameter entering, positioning verification acquisition, configuration information acquisition, safety stock, maximum stock and the like, replenishment target storage area calculation, replenishment stock acquisition according to the configuration information, replenishment calculation according to the configuration, positioning result encapsulation processing, loading recommendation and stock preemption.
It should be noted that, a process of adding or deleting a certain service only needs to add or delete a corresponding actuator and a configuration process.
Step S103, according to the configuration flow of the executor, processing the service data request; wherein the configuration flow is set to a responsibility chain mode.
In an embodiment, the configuration flow is set to a responsibility chain mode, so that the nodes on the responsibility chain guarantee sub-service independence, i.e. each node executes a corresponding sub-service. Wherein the responsibility chain mode refers to that a plurality of objects are connected by a reference of each object to the lower home to form a chain.
In some embodiments, the processing the service data request according to the configuration flow of the executor specifically includes:
executing the service data request according to the chain node on the configuration flow responsibility chain mode;
judging whether the execution is successful or not when one chain node is completed in each execution, judging whether the next chain node exists according to the linked list if the execution is successful, continuing to execute the next chain node if the next chain node exists, and returning to the data stream processing engine if the next chain node does not exist, and generating an execution success result; if not, judging whether the last chain node exists according to the linked list, and if so, executing a last chain node rollback method; and if not, returning to the data stream processing engine, and generating an execution failure result.
Preferably, each chain node executes a done doHandler event, and then determines whether the execution was successful.
In addition, it should be noted that each node in the flow is organized in the form of a linked list to form a head-to-tail bidirectional linked list.
It can be seen that each chain node is an atomic event, including forward commit doHandler event handling, and rollback handling failback methods.
As other embodiments, the processing the service data request according to the configuration flow of the executor includes:
and initializing a configuration flow according to the flow code by using a build initialization method of the class issued by the resourceHandlerExecutor service caller. And executing a corresponding configuration flow by an exec handler method of the class issued by the resourceHandlerexeutor service caller.
As a further embodiment of the present invention, after receiving a service data request and obtaining a corresponding flow code, as shown in FIG. 5, a data flow processing engine is called through an external unified call interface, and then an exec handler method corresponding to an executor entry resourceHandlerexeutor starts to execute according to a configuration flow. And processing the sub-service of the current chain node by a doHandle specific service processing method, judging whether the execution is successful, if so, judging whether the next chain node exists according to the linked list, if so, continuing to execute the next chain node, and if not, returning to the data stream processing engine to generate an execution success result. If not, judging whether the last chain node exists according to the linked list, and if so, executing a last chain node rollback method; and if not, returning to the data stream processing engine, and generating an execution failure result.
Fig. 6 is a schematic diagram of main modules of a service processing apparatus according to an embodiment of the present invention, and as shown in fig. 6, the service processing apparatus 600 includes an acquisition module 601 and a processing module 602. The acquiring module 601 receives a service data request and acquires a corresponding flow code; calling a data stream processing engine through an external unified calling interface, and further obtaining a corresponding executor according to the flow code; the processing module 602 processes the service data request according to the configuration flow of the executor; wherein the configuration flow is set to a responsibility chain mode.
In some embodiments, the processing module 602 processes the service data request according to a configuration flow of the executor, including:
executing the service data request according to the chain node on the configuration flow responsibility chain mode;
judging whether the execution is successful or not when one chain node is completed in each execution, judging whether the next chain node exists according to the linked list if the execution is successful, continuing to execute the next chain node if the next chain node exists, and returning to the data stream processing engine if the next chain node does not exist, and generating an execution success result;
if not, judging whether the last chain node exists according to the linked list, and if so, executing a last chain node rollback method; and if not, returning to the data stream processing engine, and generating an execution failure result.
In some embodiments, the processing module 602 determines whether execution was successful for each execution of one chain node, including:
and each chain node executes the completion doHandler event, and whether the execution is successful or not is judged.
In some embodiments, the linked list is a doubly linked list.
In some embodiments, the obtaining module 601 invokes a data stream processing engine through an external unified call interface, including:
the data stream processing engine is called through a calling interface provided by the resourceHandlerExecutor class.
In some embodiments, the processing module 602 includes, before processing the service data request according to a configuration flow of the executor:
and setting a configuration flow for each flow code through an Abstract resource HandlerConfiction configuration class.
In some embodiments, the processing module 602 processes the service data request according to a configuration flow of the executor, including:
