我必须使用打开的 csv 将嵌套的对象列表（StoreLocations）写入 Csv 文件。我的模型类是-

public class StoreLocation {
    private String name;
    private String city;
    private int zip;
    private String streetAndNumber;
    private List<String> keywords;
    private Double lat;
    private Double lng;
    private List<OpeningHours> openingHours;
}

public class OpeningHours {
    private String dayOfWeek;
    private String from1;
    private String to1;
}

我的写作方法——

public void getStoreLocationData(List<StoreLocation> storeLocations) throws IOException, CsvDataTypeMismatchException, CsvRequiredFieldEmptyException {
        try (
                Writer writer = Files.newBufferedWriter(Paths.get(storeLocationDataCsv))
        ) {
            StatefulBeanToCsv beanToCsv = new StatefulBeanToCsvBuilder(writer)
                    .withQuotechar(CSVWriter.NO_QUOTE_CHARACTER)
                    .build();
            beanToCsv.write(storeLocations);
        }
    }

此代码完美生成所有列，除了开放时间列表。这是当前的输出- 我宁愿有一个开放时间列，并将每个开放时间安排为一个新行。就像是 或在营业时间列内的 json …
