public void importDictDataMultipartFile file try EasyExcelreadfilegetInputStreamDictEeVoclassdictListener sheet doRead; catch IOExcept

This code is a method that reads data from an Excel file (in the form of a MultipartFile) using the EasyExcel library, and then calls a listener (dictListener) to process the data. The data is assumed to be in the form of DictEeVo objects.

The method begins by reading the input stream from the MultipartFile, and passing it to the EasyExcel.read() method. This method takes three arguments: the input stream, the class type of the data to be read (DictEeVo), and the listener to be called to process the data (dictListener).

The sheet() method is then called to specify that the data should be read from the first sheet in the Excel file. Finally, the doRead() method is called to initiate the reading process.

If an IOException occurs during the reading process, it is caught and a RuntimeException is thrown.
