S101, receiving a target page loading request; the target page loading request carries the data capacity of the target page, and the target page corresponds to a first-level cache layer.
In a specific application, when a target page loading request is received, the target page loading request can be analyzed to obtain the data capacity of a target page carried by the target page loading request, so as to read the data of the target page according to the data capacity. And the data displayed by the target page at the current moment is correspondingly stored in the first-level cache layer. The target page loading request carries the data volume of the target page, and the data volume of the target page refers to the data volume of page data required to be displayed on the target page. The type of the list data includes, but is not limited to, at least one of a number, a character string, and a letter. The first-level Cache layer includes but is not limited to session and cookie, Cache memory and other storage spaces.
For example, the data capacity of the target page carried by the target page loading request is 100 pieces of page data of the 1 st page, and the 100 pieces of page data of the 1 st page are stored in the first-level cache layer and displayed in the target page.
S102, judging whether the data capacity exists in a first-level cache layer.
In specific application, corresponding page data is searched in a first-level cache layer according to data capacity.
For example, at the current time, the target page displays page data of 100 2 nd pages (which are stored in the first level cache layer). When a target page loading request is received, if the data capacity of a target page carried by the target page loading request is analyzed to be page data of 100 pages 6, the page data of the 100 pages 6 cannot be searched in a first-level cache layer according to the data capacity, and it can be determined that the data capacity does not exist in the first-level cache layer.
S103, when the data capacity does not exist in the first-level cache layer, judging whether the data capacity exists in a second-level cache layer which meets the preset relation with the first-level cache layer.
In a specific application, when the corresponding page data is not found in the first-level cache layer according to the data capacity, the corresponding page data is found in the second-level cache layer which meets the preset relation with the first-level cache layer according to the data capacity, and when the page data corresponding to the data capacity is found, the page data corresponding to the data capacity is displayed in a target page. The preset relationship can be specifically set according to actual conditions.
In one embodiment, step S102 includes:
searching corresponding data in the second-level cache layer according to the data capacity;
when the corresponding data is found in the second-level cache layer, judging that the data capacity exists in the second-level cache layer;
when the corresponding data is not found in the second-level cache layer, judging that the data capacity does not exist in the second-level cache layer; the second-level cache layer is used for storing data with a preset numerical value as the difference value of the page number of the data in the first-level cache layer.
In a specific application, the preset relationship is that a difference of page numbers between page data stored in the first-level cache layer and page data stored in the second-level cache layer is a preset value, that is, page data having a difference of page numbers between the page data stored in the first-level cache layer and page data stored in the second-level cache layer and the first-level cache layer is a preset value is cached in the second-level cache layer satisfying the preset relationship with the first-level cache layer. The page number difference is a difference between the page number of the page data in the first-level cache layer and the page number of the page data in the second-level cache layer.
In specific application, searching corresponding page data in a second-level cache layer according to the data capacity, and judging that the data capacity exists in the second-level cache layer when the corresponding page data is searched in the second-level cache layer; and when the corresponding page data is not found in the second-level cache layer, judging that the data capacity does not exist in the second-level cache layer.
For example, a preset value is set to be 1, and the corresponding preset relationship is that the difference of the page numbers of the page data is 1; that is, in the second level cache layer, page data having a difference of 1 from the page number of the page data in the first level cache layer is stored, that is, page data of a previous page and page data of a next page of the page data in the first level cache layer are stored in the second level cache layer.
For example, at the current time, the target page displays page data of 100 2 nd pages (which are stored in the first-level cache layer), and page data of 100 1 st pages and page data of 100 3 rd pages are cached in the second-level cache layer which meets the preset relationship with the first-level cache layer correspondingly; when a target page loading request is received, if the page data of the target page carried by the target page loading request and having the data capacity of 100 pages 6 is analyzed, the page data of the 100 pages 6 needs to be searched in the second-level cache layer according to the data capacity, so as to judge whether the data capacity exists in the second-level cache layer which meets the preset relation with the first-level cache layer.
And S104, when the data capacity exists in a second-level cache layer which meets the preset relation with the first-level cache layer, loading data corresponding to the data capacity from the second-level cache layer, and displaying the data on a target page.
In a specific application, if the corresponding page data is found in the second level cache layer which meets the preset relation with the first level cache layer according to the data capacity, the page data corresponding to the data capacity is loaded from the second level cache layer and is displayed on a target page. The second level cache layer may be an internal storage space of the CPU or a memory.
For example, at the current time, the target page displays page data of 100 2 nd pages (which are stored in the first-level cache layer), and page data of 100 1 st pages and page data of 100 3 rd pages are cached in the second-level cache layer which meets the preset relationship with the first-level cache layer correspondingly; when a target page loading request is received, if the data capacity of a target page carried by the target page loading request is analyzed to be page data of 100 1 st pages, the page data of the 100 1 st pages can be found in a second-level cache layer which meets a preset relation with a first-level cache layer according to the data capacity, and the page data loaded with the 100 1 st pages is stored in the first-level cache layer and is displayed on the target page.
In one embodiment, the preset value is set to be 2, and the corresponding preset relationship is that the difference between the page numbers of the page data is 2, that is, the page data of the upper 2 pages and the page data of the lower 2 pages of the page data in the first-level cache layer are stored in the second-level cache layer.
For example, the page data in the first-level cache layer is 100 pieces of data of the 5 th page, and correspondingly, 200 pieces of page data of the upper 2 pages of the page data in the first-level cache layer (that is, 100 pieces of page data of the 3 rd page and 100 pieces of page data of the 4 th page) and 200 pieces of page data of the lower 2 pages of the page data in the first-level cache layer (that is, 100 pieces of page data of the 6 th page and 100 pieces of page data of the 7 th page) may be obtained and stored in the second-level cache layer.
And S105, when the data capacity does not exist in the second-level cache layer which meets the preset relation with the first-level cache layer, loading data corresponding to the data capacity from the third-level cache layer, and displaying the data on a target page.
In a specific application, if the page data corresponding to the data capacity is not found in the second level cache layer satisfying the preset relationship with the first level cache layer, the page data corresponding to the data capacity is loaded in the third level cache layer and displayed on the target page.
The third level cache layer is used for storing the database data of the list, which may include but is not limited to a database or a hard disk.
For example, the page data in the first-level cache layer is 100 pieces of 5 th page data, and the corresponding second-level cache layer satisfying the preset relationship with the first-level cache layer includes 100 pieces of 3 rd page data and 100 pieces of 4 th page data; when the page data of the target page carried by the target page loading request is analyzed, the data capacity of the target page is 100 page data of the 1 st page, the data capacity is judged not to exist in the second-level cache layer which meets the preset relation with the first-level cache layer, the 100 page data of the 5 th page are loaded from the third-level cache layer, and are stored in the first-level cache layer and displayed on the target page.
In one embodiment, the method for displaying list data based on hierarchical cache further includes:
when data corresponding to the data capacity is loaded, storing the loaded data in a first-level cache layer;
and updating the data in the second-level cache layer.
In a specific application, if the corresponding page data is found in the first-level cache layer according to the data capacity, it can be understood that at the current time, the target page is displaying the page data corresponding to the data capacity of the target page carried in the target page loading request, and the second-level cache layer satisfying the preset relationship with the first-level cache layer is storing the page data satisfying the preset relationship with the page data corresponding to the data capacity.
For example, at the present time, the target page displays page data of 100 pages 6 (which are stored in the first-level cache layer), and the preset relationship is that the difference between the page numbers of the page data is 1. When a target page loading request is received, analyzing page data of a target page, which has a data capacity of 100 pages 6 and is carried by the target page loading request, and correspondingly finding the page data of the 100 pages 6 in a first-level cache layer according to the data capacity, that is, at the current time, the target page is displaying the page data of the 100 pages 6 corresponding to the target page loading request, so that the target page loading request can be understood to obtain: at the current moment, page data meeting the preset relation with the page data of the 6 th page of 100 pieces is stored in the second-level cache layer.
In a specific application, the second-level cache layer satisfying the preset relationship with the first-level cache layer is used for caching page data with the page number difference value of the page data in the first-level cache layer as a preset numerical value. Therefore, after loading the page data corresponding to the data capacity, storing the loaded page data corresponding to the data capacity in the first-level cache layer, and updating the data in the second-level cache layer, including:
if the data capacity is detected to exist in a second-level cache layer which meets a preset relation with a first-level cache layer, page data corresponding to the data capacity is loaded from the second-level cache layer, the loaded page data is stored in the first-level cache layer, and the page data is displayed on a target page; and acquiring corresponding data (namely the data meeting a preset relation with the data in the primary cache layer) from the third-level cache layer so as to update the data in the second-level cache layer.
If the data capacity is detected to exist in the third-level cache layer, page data corresponding to the data capacity is loaded from the third-level cache layer, and the loaded page data is stored in the first-level cache layer and displayed on a target page; and acquiring corresponding data from the third-level cache layer to update the data in the second-level cache layer.
For example, at the present time, the target page displays page data of 100 2 nd pages (which are stored in the first-level cache layer), page data of 100 1 st pages and page data of 100 3 rd pages are cached in the second-level cache layer that satisfies the preset relationship with the first-level cache layer, and the preset relationship is that the difference between the page numbers of the page data is 1. When a target page loading request is received, if the data capacity of a target page carried by the target page loading request is analyzed to be page data of 100 pages 3, judging that the data capacity exists in a second-level cache layer which meets a preset relation with a first-level cache layer, loading the page data of the 100 pages 3 from the second-level cache layer, storing the page data in the first-level cache layer, displaying the page data on the target page, acquiring the page data of the 100 pages 2 and the page data of the 100 pages 4 from the third-level cache layer, and updating the data in the second-level cache layer. When a target page loading request is received, if the data capacity of a target page carried by the target page loading request is analyzed to be page data of 100 8 th pages, the data capacity is judged to be in a third-level cache layer, the page data of the 100 8 th pages are loaded from the third-level cache layer, stored in a first-level cache layer and displayed on the target page, the page data of the 100 7 th pages and the page data of the 100 9 th pages are obtained from the third-level cache layer, and the data in the second-level cache layer are updated.
In one embodiment, before step S101, the method includes:
s201, the list data are classified, and the list data are stored in the corresponding cache layer according to the data grades.
In specific application, all the list data are acquired in advance, the list data are classified, and the corresponding list data are stored in the corresponding cache layer according to each data grade.
For example, when page data of page 1 in the list is classified as first-level data, the page data of page 1 is stored in a first-level cache layer.
As shown in fig. 2, in one embodiment, step S201 includes:
s2011, acquiring data meeting preset conditions in the list data, serving as first-level data, storing the first-level data in a first-level cache layer, and displaying the first-level data on a target page;
s2012, acquiring data meeting a preset relation with the first-level data, taking the data as second-level data and storing the data in a second-level cache layer;
and S2013, taking the database data of the list as third-level data and storing the third-level data in a third-level cache layer.
In specific application, all list data are obtained in advance, data meeting preset conditions in the list data are stored in a first-level cache layer as first-level data, and the first-level data are displayed on a target page. The preset condition may be a page with the maximum use frequency;
for example, in general, the page with the highest frequency of use is the 1 st page, and the corresponding page data of the 1 st page of 100 pieces of data meeting the preset condition is stored in the first-level cache layer as the first-level data and displayed on the target page.
In specific application, determining page data which meets a preset relation with the primary data in the list data, taking the page data as secondary data and storing the page data in a secondary cache layer; for example, if the preset relationship is that the difference between the page numbers of the page data is 1, when the primary data is page data of 100 1 st pages, the page data of 100 2 nd pages that satisfy the preset relationship with the primary data is correspondingly stored in the secondary cache layer as secondary data.
In a specific application, all data in the database of the list is used as three-level data, and the three-level data is stored in the internal storage space. The database may be a relational database (e.g., MySQL, SqlServer), or a non-relational database (e.g., Redis).
It can be understood that, when storing the third-level data and the second-level data, in order to ensure the stability and the order of the data, the third-level data and the second-level data are respectively stored in different internal storage spaces.
The method has the advantages that the list data are stored in a grading mode in advance, the first-grade data are stored in the non-internal storage space, the internal storage space occupied by the list data in the storage process is reduced, a Central Processing Unit (CPU) and the memory occupancy rate are reduced, the data of the page corresponding to the target page loading request can be acquired quickly when the target page loading request is received, and the display performance and the system response speed are improved.
