Answer 1

Use this snippet for instantiating CSVWriter .

CSVWriter csvWriter = new CSVWriter(writer,
                                    '|',
                                    CSVWriter.NO_QUOTE_CHARACTER,
                                    CSVWriter.DEFAULT_ESCAPE_CHARACTER,
                                    CSVWriter.DEFAULT_LINE_END);

只需将管道字符作为默认分隔符传递即可。

CSVWriter csvWriter = new CSVWriter(writer,'|');
