s1: extracting all first data tables for storing source website data from a source website database, and extracting data in each first data table to form a compressed file;
in S1, extracting the data in each first data table to form a compressed file may include:
(1) for each first data table, determining a classification identifier corresponding to the first data table according to the table name of the first data table; that is, for each first data table, a classification identifier is assigned according to the table name, such as: if the table name of the first data table is wcm _ cms _ news, the classification identifier of the first data table is a news identifier; and the table name of the first data table is wcm _ cms _ product, and the classification identifier of the first data table is the product identifier. It should be noted that, in this embodiment, the first data tables and the table names are in a one-to-one correspondence relationship, that is, one table name only corresponds to one first data table, and the case that the table names of a plurality of first data tables are the same does not occur.
(2) Determining a data extraction method corresponding to the first data table according to the classification identification of the first data table; for example, if the classification flag is wccm _ cms _ news, it may be determined that the data extraction method of the first data table is a doExportData method in the class WcmCtsNewsServiceImpl. Of course, the corresponding relationship between other classification identifiers and the data extraction method may also be included, which is not described in this embodiment.
(3) Extracting data in the first data table by using a data extraction method to obtain a data file corresponding to the first data table;
specifically, all table fields in the first data table are traversed by using a data extraction method, and data corresponding to each table field are stored in a json array, wherein the json array is an array in a json format. And then analyzing the data in the json array into character strings by using a method of writing the character strings into a file, and writing all the character strings into a data file corresponding to the first data table to obtain the data file corresponding to the first data table. Traversing all table fields in the first data table, summarizing and analyzing data corresponding to all the table fields into json data texts, and storing the json data texts in data files named by the table names of the first data table, wherein the data files named by the table names of the first data table are the data files corresponding to the first data table.
By utilizing the steps, the data files corresponding to each first data table can be obtained, namely the first data tables correspond to the data files one by one. The data file shares the classification identifier of the corresponding first data table, that is, the data file of the first data table can be determined according to the classification identifier of the data file.
(4) And compressing all the data files to form compressed files.
Specifically, an object is created by using a File class to obtain a null compressed File, and then all data files are written into the null compressed File in a File stream form, so that a compressed File is formed.
