The folder in this embodiment may be a set used to assist a user in managing related files generated in banking system services. The file is an information set stored on a computer by taking a computer hard disk as a carrier, the type of the file can be a text document, a picture, a program and the like, and the document file is taken as an example in the embodiment. The file name is an identifier carried by a file, and the name of the file usually consists of a main name and an extension, wherein the extension refers to a letter sequence after the last point (.) in the file name. For example, HTML (HyperText Markup Language) files are identified by the. htm or. HTML extension; a GIF (Graphics exchange Format) file is identified with a GIF extension. The purpose is to distinguish between files of different formats, with different information having different storage formats. After the bank system is optimized, some inconsistency occurs in the files, so that the first file to be compared and the second file to be compared may not be completely identical.

Illustratively, S110 may include: acquiring a first file to be compared under a first folder to be compared according to the file comparison list; and for each first file to be compared, determining a second file to be compared corresponding to the current file to be compared from the second folder to be compared according to the similarity of the file names.

And determining a second file to be compared corresponding to the first file to be compared in the second folder to be compared according to the similarity of the file names.

S120, respectively obtaining the feature information of the first file to be compared and the second file to be compared based on a preset comparison rule, and comparing the feature information to generate a first comparison list.

The characteristic information may include, but is not limited to, a file name, a file size, a file format, a file authority, a file generation time, a file code, a file content, and other information. The preset comparison rule may be a rule preset according to different service scenarios and used for selectively or customizing the feature information. For example, for service scenarios such as application program upgrade and database migration, the comparison rule may be set to select other feature information for comparison except for the file generation time and the file modification time.

The first comparison list may be a list of comparison results generated by comparing the first file to be compared with the second file to be compared according to the preset comparison rule.

In this embodiment, the feature information of the first file to be compared in the file comparison list may be obtained one by one, the obtained feature information of the first file to be compared is used as one column in the table, the feature information corresponding to the second file to be compared is used as another column in the table, the feature information in the two columns in the table is compared one by one, a comparison result is obtained, and the comparison result is recorded in a column different from the two columns in the table. And after the first files to be compared in the file comparison list are compared with the characteristic information, generating a first comparison detailed list according to the list.

The characteristic information field is a field for identifying file attributes, such as file name, file size, file format, file authority, file generation time, file coding, file content and the like. In this embodiment, the characteristic information fields to be compared may be obtained according to the service requirement, or all the fields may be selected for comparison, or a part of the fields may be selected for comparison, for example, when the characteristic information comparison between the file format and the file authority is to be performed, only two fields of "file format" and "file authority" need to be selected.

Illustratively, the first characteristic information and the second characteristic each contain one or more items of a file name, a file size, a file format, a file authority, a file generation time, and a file content; generating a first comparison list according to the first characteristic information and the second characteristic information, wherein the first comparison list comprises: generating characteristic values according to one or more items of file names, file sizes, file formats, file permissions, file generation time and file contents, and comparing the first characteristic information with the second characteristic information based on the characteristic values to obtain characteristic comparison results; and generating a first comparison list based on the feature comparison result, the first file name to be compared and the second file name to be compared.

The characteristic value may refer to a specific characteristic value of the characteristic information of the file. For example, the feature value may be a hash value. The setting Algorithm may be MD5(Message-Digest Algorithm, widely used cryptographic Hash function) Algorithm, SHA1(Secure Hash Algorithm), CRC32(Cyclic Redundancy Check) Algorithm, and the like. In this embodiment, the feature value calculation for the file content is performed by using the MD5 hash algorithm.

If the comparison rule is set according to the service scene as a characteristic value corresponding to the file content, the first file to be compared and the second file to be compared are compared, the file content of the first file to be compared in the file comparison list is obtained, and the characteristic value of the file content is calculated by adopting a hash algorithm. And acquiring the file content of a second file to be compared corresponding to the first file to be compared, and calculating the characteristic value of the file content by adopting a Hash algorithm. And comparing the two characteristic values to obtain a characteristic comparison result. And if the deviation of the characteristic values does not exceed the set threshold value, determining that the file contents of the first file to be compared and the second file to be compared are the same.

And if the deviation exceeds the characteristic value of the set threshold, determining that the characteristic information corresponding to the characteristic values of the first file to be compared and the second file to be compared is different.

And comparing the characteristic values of the characteristic information of the first files to be compared in the file list one by one until all the first files to be compared in the file list are compared with the characteristic values of the characteristic information. And generating a first comparison list according to the feature comparison result of each file, the first file name to be compared and the second file name to be compared.

S130, when the characteristic information is inconsistent, comparing the file contents of the first file to be compared with the corresponding second file to be compared to generate a second comparison list.

The second comparison list may be a list of comparison results generated by comparing the contents of the first file to be compared with the contents of the second file to be compared. Optionally, after the second comparison list is generated, the comparison list may be output to a pre-specified folder, so that a user can conveniently check a place where the first to-be-compared file is inconsistent with the second to-be-compared file in a subsequent process. When the feature information of the two files is inconsistent, the file contents of the two files need to be compared. Specifically, the information recorded in the two files to be compared can be compared by using the EXCEL table, so as to obtain a content comparison result. And generating a second comparison list according to the content comparison result of each file, the first file name to be compared and the second file name to be compared.

And S140, generating and displaying comparison result display contents according to the first comparison list and the second comparison list.

The embodiment can divide the display comparison result according to the first comparison list and the second comparison list.

For example, a feature comparison summary is generated according to the first comparison list, and the feature comparison summary is displayed to display the comparison result from the first hierarchy. The characteristic comparison summary is a form of showing a characteristic comparison result of the file through a file comparison brief report. Specifically, the summary of feature comparison may show the feature comparison result of the file from the aspects of the total number of the comparison files, the comparison result, the file occupation ratio, the comparison time consumption, and the like.

And further optimizing the file contents of the first file to be compared and the corresponding second file to be compared when the characteristic information is inconsistent, and generating a second comparison detailed table. Wherein explanations of the same or corresponding terms as those of the above embodiments are omitted. Referring to fig. 2, the file comparison method provided in this embodiment specifically includes the following steps:

s210, obtaining first files to be compared under the first files to be compared, and determining second files to be compared corresponding to the first files to be compared from the second files to be compared according to file names, wherein the first files to be compared and the second files to be compared are respectively the files before and after the bank system is optimized.

S220, respectively obtaining the feature information of the first file to be compared and the second file to be compared based on a preset comparison rule, and comparing the feature information to generate a first comparison list.

Specifically, the comparison of the feature information is executed once when one file is read into the EXCEL, and then the comparison of all files in the file list corresponding to the folder to be compared is read again until the comparison of all files in the file list corresponding to the folder to be compared is completed, so that the first target file to be compared and the corresponding second target file to be compared, of which the feature information is inconsistent, are determined.

And S230, traversing the first comparison list, and determining the first target file to be compared and the corresponding second target file to be compared, wherein the characteristic information of the first target file to be compared is inconsistent with the characteristic information of the second target file to be compared.

In this embodiment, the comparison result is determined in a form of a traversal table as a first target file to be compared and a corresponding second target file to be compared, where the first target file and the corresponding second target file are inconsistent in feature information, specifically, comparison of feature information is performed once every time one file is read into the EXCEL, and then the file is read again until comparison of all files in a file list corresponding to the folder to be compared is completed, so that the first target file to be compared and the corresponding second target file to be compared, where the feature information is inconsistent, are determined.

S240, judging whether the file coding formats of the first target file to be compared and the corresponding second target file to be compared are the same.

The file code is used for indicating the number of bytes occupied by each character in the file content. For example, file encoding formats include ANSI encoding, UTF-8 encoding, UTF-16 encoding, GB2312, and the like. In this embodiment, the encoding format of the first file to be compared is obtained, and the encoding format of the second file to be compared is obtained, and whether the encoding formats of the two files are the same or not is compared. And S250, if the file coding formats are different, adjusting the file coding formats to be the same through a preset transcoding mode.

In one case, the preset transcoding mode is to convert the encoding format of the first file to be compared into the same encoding format as the second file to be compared. In a special case, the preset transcoding mode is to convert the encoding format of the second file to be compared into the same encoding format as the first file to be compared.

Suppose that the first file to be compared is a file encoded by using the UTF-8 encoding format, and the second file to be compared is a file encoded by using the GB2312 encoding format. The preset transcoding mode is to convert the coding format of the first file to be compared into the coding format which is the same as that of the second file to be compared. Then, the encoding format of the first file to be compared may be restored to the Unicode encoding, and then the Unicode encoding may be converted into the GB2312 encoding, so as to convert the encoding format of the first file to be compared into the GB 2312.

The preset separation rule is used for dividing the file content of each target file to be compared. It should be noted that the preset separation rule may be flexibly configured according to an actual service scenario, and a specific implementation manner of the preset separation rule is not limited in the embodiment of the present invention. For example, the preset separation rule may be automatic line feed according to the number of characters, and the like.

After the line feed processing is performed on the file content of each column by using the preset separation rule, the line number of each line may be displayed in the EXCEL file, or the line number may not be displayed.

S270, comparing the first target files to be compared and the corresponding second target files to be compared with each other in the same file coding format line by line to obtain content comparison results, wherein the content comparison results comprise file content comparison results, line numbers and line comparison results.

Illustratively, a row in the file contents of the two target files to be compared is read respectively according to the row number for comparison, so as to obtain a row comparison result corresponding to the row number. And repeating the steps, reading the file contents corresponding to the line numbers in sequence, and comparing until the file contents of the last line are compared. And determining a file content comparison result according to the row comparison result corresponding to each row number.

Specifically, when the row comparison results corresponding to the row numbers are the same, it is determined that the file content comparison results are the same. And when the row comparison results corresponding to at least one row number are different, determining that the comparison results of the file contents are different.

S280, generating a second comparison list according to the content comparison result, the first target file name to be compared and the second target file name to be compared.

Illustratively, a second comparison list containing comparison details of the first target file name to be compared, the second target file name to be compared, the content comparison result and the like is generated. And saving the second comparison list to a preset folder. Specifically, comparison details with different file contents can be screened from the second comparison detail table according to the content comparison result and stored in the first folder, and comparison details with the same remaining content can be stored in the second folder. And when a query request for the comparison details of the files with different file contents is detected, acquiring the corresponding comparison details in the first folder and displaying the comparison details. Because the comparison details with different file contents are separately stored, the data amount required to be processed by the query request can be reduced, and the query speed of the query request is improved.

And S290, generating and displaying comparison result display contents according to the first comparison list and the second comparison list.

Illustratively, generating a first-layer comparison result display content according to the total number of comparison files, the number of inconsistent files, the proportion of inconsistent files and the comparison time consumption contained in the first comparison list, and displaying the first-layer comparison result. And acquiring a comparison detail checking request, generating a second layer of comparison result display content according to the file existence information and the file content comparison result contained in the second comparison detail table, and displaying the second layer of comparison result display content. And acquiring a viewing request for the file with inconsistent file content, generating a third layer of comparison result display content according to the row number and the row comparison result of the file with inconsistent file content, and displaying the third layer of comparison result display content.

For example, as shown in fig. 3, the TXT file is taken as an example in fig. 3 to show the result of the first alignment. The information of the total number of comparison files, the number of files with different comparison results, the ratio of different numbers of files, the time consumption of comparison and the like in the first comparison can be obtained.

Table 1 shows a second comparison list generated when the contents of the documents are compared with each other for different documents.
