Java API for Exporting Data to File
The given code is a Java method that exports data to a file. It is annotated with Swagger's '@ApiOperation' annotation, which provides metadata about the API operation.
The method is called 'exportBatch' and takes the following parameters:
- 'HttpServletResponse response': The response object used to send the exported file to the client.
- 'HttpServletRequest request': The request object used to get information about the client's request.
- 'ProductDto entity': An object representing the data to be exported.
The method returns an 'ObjectRestResponse' object, which is a response wrapper that includes the HTTP status, a message, and a result code. The 'exportBatch' method calls the 'exportBatch' method of the 'entityService' object (which is not shown in the code) to handle the export process. If any exception occurs during the export process, it catches the exception and returns a new 'ObjectRestResponse' object with an HTTP status of 500 (Internal Server Error), a message of '导出失败' (Export failed), and a result code of -1.
Overall, this method is used to export data to a file in response to a client request.
