And 106, executing the loaded items in the memory according to the execution sequence of the loaded items.
in this embodiment, the load item execution order is the order of the load scheduling center for executing each load item that needs to load data, and the load item execution according to the load item execution order can clear the load order among the load items.
The data loading method and the data loading device call one or more components through a preset loading scheduling center, receive and store the loading items which are generated by the one or more components and contain the priority identifications, sequence the loading items according to the priority identifications to obtain a loading item execution sequence, and execute the loading items according to the loading item execution sequence. The method and the device have the advantages that the usable loading sequence is available when each component loads data, and the problem that application software cannot be normally used due to the fact that some loading items can not be normally called possibly because the loading sequence among the loading items is difficult to clear is solved.
As shown in fig. 2, in one embodiment, there is provided a data loading method, including:
Step 202, one or more components are called through the load scheduling center, and corresponding load items are generated according to the one or more components.
In this embodiment, before data loading is to be performed, each component that needs to be performed with data loading is called by the load scheduling center, so as to form a general interface for returning a load item. Specifically, one or more components generate corresponding loading items and priority identifications corresponding to each loading item, and the one or more components send the generated loading items and the corresponding priority identifications to the load scheduling center through a universal interface for returning the loading items. The loading item comprises loading content required by data loading, and can be, for example, a download address book, a download personal information and a download grouping list.
and step 204, receiving the loading items generated by one or more components through the loading scheduling center, and storing the loading items in a memory, wherein the loading items comprise corresponding priority identifications.
In this embodiment, the load scheduling center refers to a program for managing the loaded items generated by the components, which is set at the software development stage, and the load scheduling center can call one or more components, thereby implementing management of the loaded items generated by the one or more components and being responsible for maintaining the loading state of each loaded item. The loading scheduling center receives and stores the loading items generated by one or more components, only one component or a plurality of components may be used in the data loading process, and each component may generate one loading item or a plurality of loading items. Each loading item comprises a corresponding priority identification, the priority of each loading item is preset in the software development stage, and the component generates the loading item comprising the corresponding priority identification according to the preset priority.
and step 206, sequencing the loading items according to the priority identifications through the loading scheduling center to generate a loading item execution sequence.
In this embodiment, the load scheduling center obtains the priority level of each load item by identifying the priority identifier corresponding to each received load item, and generates a load item execution sequence according to the priority level of each load item, so as to manage the load items generated by each component. Specifically, as shown in fig. 3, the load scheduling center manages a load item configured with a priority generated by each component, stores the received load items, sorts the load items according to the priority, schedules the load items according to the sorted order in the data loading process, and implements data loading through interface calling of the component corresponding to the load item. The priority-configured add-ons are generated by components, each of which may generate one or more add-ons according to different business scenarios.
in step 208, the load items in memory are executed in load item execution order.
In this embodiment, when data loading is performed, data loading is performed according to the execution order of the load items. And arranging the loading items according to the high and low priority order through a loading scheduling center, loading the loading items with high priority, and loading the loading items with low priority after the loading of the loading items with high priority is finished. For example, in a specific service scenario, the load scheduling center calls the component 1, the component 2, and the component 3, receives the load item a and the load item B generated by the component 1, and the load item C generated by the component 2 and the load item D generated by the component 3, and sorts the load items according to priority identifiers included in the load items A, B, C and D, where the priority of the load item a and the priority of the load item D are high, the priority of the load item C is medium, the priority of the load item B is low, the generated load item execution order is that the load items a and D are executed first, the load item C is executed after the execution of the load items a and D is completed, and the load item B is executed after the execution of the load item C is completed. Thus clearing the load order between load A, B, C and D, and data loading occurs in the load execution order.
In one embodiment, the step of generating the order of execution of the load items comprises: acquiring the priority level of each loading item according to the priority level identification; setting the loading items with the same priority level as the same execution sequence; and setting the execution sequence of the loading items with different priority levels according to the priority levels.
in this embodiment, the load items received by the load scheduling center include corresponding priority identifiers, where the priority identifiers are identifiers used to uniquely identify the priority level of each load item, and generally include numbers, letters, or other special symbols with preset digits. Specifically, the load scheduling center may receive a plurality of load items generated by one or more components, and the priority levels of the respective load items may be the same or different, so as to avoid that the load items cannot be called normally, the load items with the same priority level should be set to the same execution order, the load items with different priority levels should be set to the execution order according to the priority levels, when data loading is performed, the load items in the same execution order with the higher priority levels are loaded first, and when all the load items with the higher priority levels are executed, other load items in the execution order are loaded.
In one embodiment, the step of executing the load items in the memory in the load item execution order comprises: executing the load items with the front priority according to the execution sequence of the load items; judging whether the execution of the loading item with the prior priority is finished, if so, marking the state of the loading item with the prior priority as the execution completion through a loading scheduling center; and executing the subsequent-priority loading items according to the execution order of the loading items, wherein the subsequent-priority loading items are the loading items with the priority after the previous-priority loading items.
In this embodiment, the load item with the priority preceding and the load item with the priority succeeding are relative concepts, and the load item with the priority preceding is a load item with a priority higher than that of the load item with the priority succeeding by one level. Specifically, the load scheduling center may receive multiple load items generated by one or more components, the multiple load items may generate a load item execution order of multiple priority levels according to the corresponding priority identifier, when data is loaded, the load item with the highest priority level needs to be loaded first, and when it is determined that the load item with the highest priority level is executed completely, the load item with the lower priority level is loaded, so that the data loading process is performed according to the execution order generated by the load scheduling center. When the loading item with the prior priority is judged to be completely executed, the corresponding marking is carried out through the loading scheduling center, so that the application software can acquire the information that the loading item with the prior priority is completely executed, and the application software can control the execution condition of data loading. For example, the loading scheduling center receives that the loading items are a downloading address list, a downloading personal information and a downloading grouping list, the loading scheduling center sorts the loading items according to corresponding priority identifiers, if the priorities of the downloading address list and the downloading grouping list are high and the priorities of the downloading personal information are low, the generated execution sequence of the loading items is that the downloading address list and the downloading grouping list are executed firstly, after the downloading of the address list and the downloading grouping list is completed, the result is fed back to the loading scheduling center, the loading scheduling center marks the execution state, then the loading scheduling center judges whether the loading items with high priorities are completely executed or not, if so, the loading items with low priorities are executed, namely the downloading personal information is started until all the loading items are executed.
Further, in the conventional technology, since the loading scheduling center does not control the loading of the data by each loading item, it is difficult for the application software to uniformly determine whether the loading of each loading item is completed, and when the loading is completed, the corresponding exception handling is required if the loading item is abnormal, or even manual handling is required. In this embodiment, the application software can control the execution state of each loading item through the load scheduling, if an abnormal condition occurs in the execution process, the corresponding loading item performs corresponding abnormal processing, and each loading item is responsible for processing the abnormal condition occurring in itself and feeding back the final result to the load scheduling center. For example, in the setting that each add item handles the own abnormal condition, the add item may be set to perform data loading again when the abnormal condition occurs, and if the abnormal condition still occurs during data loading again and reaches the preset number of times, it is determined that the data loading is completed, and the data loading is fed back to the load scheduling center.
in one embodiment, the step of executing the load items in the memory in the load item execution order comprises: the loading item in the memory is executed by the load dispatch center invoking an interface of one or more components.
In this embodiment, the component is an actual executor loaded in the data loading, the load scheduling center and the component corresponding to the load item are connected through the load item, the load item is generated by the corresponding component, and data loading also needs to be performed by calling an interface of the corresponding component.
