如何在使用 openCSV 写入文件时添加分隔符.csv.

Question

我正在用java编写一个csv文件，我想用'|'作为分隔符编写csv文件。我该如何在我的代码中执行操作。

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();
}
}

Answer 1

使用此代码段实例化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,'|');
