如何在使用 java/opencsv 写入 csv 时转义换行符

Question

我有一个 CSV 文件，它保存为 Bean。一列包含 HTML 标签，包括 特点。虽然使用 opencsv 读取不是问题，但当我编写新的 csv 时，它实际上会创建一个新的换行符/行。

这是我尝试过的：

File file = new File(outDirectory, this.outputCSVName);

    try (
            Writer writer = Files.newBufferedWriter(Paths.get(file.toURI()));
    ) {
        StatefulBeanToCsv<Shopify> beanToCsv = new StatefulBeanToCsvBuilder(writer)
                .withQuotechar(CSVWriter.NO_QUOTE_CHARACTER)
                .withApplyQuotesToAll(true)[![enter image description here][1]][1]
                .withEscapechar('\n')
                .withLineEnd("\n") // just to test
                .withSeparator(',')
                .build();

        beanToCsv.write(data);
        writer.close();

    } catch (CsvRequiredFieldEmptyException | IOException e) {
        throw new RuntimeException(e);
    } catch (CsvDataTypeMismatchException e) {
        throw new RuntimeException(e);
    }

这是它在数组列表中的样子：

如何将其写为字符串？另外我如何将其导出为 UTF-8 编码文件？

Answer 1

@g00se 的建议让我删除了 .withEscapechar(' ') 之后效果很好。我的最终导出如下所示：

File file = new File(outDirectory, this.outputCSVName);

    try (
            Writer writer = Files.newBufferedWriter(Paths.get(file.toURI()), StandardCharsets.UTF_8);
    ) {
        StatefulBeanToCsv<Shopify> beanToCsv = new StatefulBeanToCsvBuilder(writer)
                .withSeparator(',')
                .build();

        beanToCsv.write(data);
        writer.close();
        return "Export OK";
    } catch (CsvRequiredFieldEmptyException | IOException e) {
        throw new RuntimeException(e);
    } catch (CsvDataTypeMismatchException e) {
        throw new RuntimeException(e);
    }
