如何在使用 openCSV 写入 .csv 文件时添加分隔符

Question

我正在用java编写一个csv文件，我想用'|'编写csv文件 作为分隔符。我该怎么做我的代码。

这是我的Java代码：

public void createCsv(User user) {
    
    try( FileWriter writer = new FileWriter(CSV_FILE_NAME,true);
            CSVWriter csvWriter = new CSVWriter(writer,
                    CSVWriter.DEFAULT_SEPARATOR,
                    CSVWriter.NO_QUOTE_CHARACTER,
                    CSVWriter.DEFAULT_ESCAPE_CHARACTER,
                    CSVWriter.DEFAULT_LINE_END);
            
            CSVReader reader = new CSVReader(new FileReader(CSV_FILE_NAME));){
        
        if(reader.readNext() !=null) {
            csvWriter.writeNext(new String[]{user.getFirstName(), user.getLastName()});             
        }else {
            String[] headerRecord = {"First Name", "Last Name"};
            csvWriter.writeNext(headerRecord);

            csvWriter.writeNext(new String[]{user.getFirstName(), user.getLastName()});             
        }
        
        
        
    } catch (IOException e) {
        
        e.printStackTrace();
    }
}

使用此代码段来实例化CSVWriter.

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