如何在uniVocity CsvWriter中附加不带引号的空或空值

[英]How to append empty or null values without quote in uniVocity CsvWriter

原文 2019-05-30 11:38:33 2 1 java/ csv/ univocity

Im trying to append row, using CSVWriter by uniVocity 我正在尝试通过uniVocity使用CSVWriter追加行

When i set 当我设定

settings.setQuoteAllFields(true);

then all fields are quoted, this is logical, but can i set any settings NOT to apply quotes in empty or null fields? 那么所有字段都用引号引起来，这是合乎逻辑的，但是我可以设置任何设置以不对空字段或空字段应用引号吗？

For example, when i call 例如，当我打电话

String stringRow = writer.writeRowToString(new String[] {"null","","","123"})

the stringRow is stringRow是

"";"";"";"123"

but i need 但是我需要

;;;"123"

How can i set this? 我该如何设置？
