自己写的代码：

public static List<String[]> readCSV(String fileName, List<String> rowList){
            List<String[]> records = new ArrayList<>();
            try{
                File inFile = new File(fileName);
                BufferedReader read = new BufferedReader(new FileReader(inFile));
                CSVReader reader = new CSVReader(read,',');
                int row = 0;
                String[] strArr = null;
               
                while((strArr = reader.readNext())!=null){              
                    records.add(strArr);        
                }
                read.close();
                reader.close();
                
            } catch (FileNotFoundException ex) {
                System.err.println("没找到文件！"+fileName);
                throw new TestngCSVException(TestngCSVException.FILE_FORMAT,"没找到文件！"+fileName,ex);
            } catch (IOException ex) {
                System.err.println("读写文件出错！"+fileName);
                throw new TestngCSVException(TestngCSVException.FILE_FORMAT,"读写文件出错！"+fileName,ex);
            } catch (Throwable e){
                System.err.println("出现未知异常");
                throw new TestngCSVException(TestngCSVException.ABNORMAL_EXIT,"在读文件 "+fileName+" 时出现未知异常！",e);
            }
        }
