两步解决opencsv 设置@CsvBindByPosition(position = 0)导致@CsvBindByName(column = “批次号“) 标题头不写入的问题

//获取实体类中的所有column
private static <T> String[] getHeaderNames(Class<T> clazz) {
    HeaderColumnNameMappingStrategy<T> mappingStrategy = new HeaderColumnNameMappingStrategy<>();
    mappingStrategy.setType(clazz);
    List<String> headers = new ArrayList<>();
    Field[] fields = CustomBean .class.getDeclaredFields();
    for (Field field : fields) {
        CsvBindByName annotation = field.getAnnotation(CsvBindByName.class);
        CsvBindByPosition annotationp = field.getAnnotation(CsvBindByPosition.class);
        if (annotation != null&&annotationp !=null) {
            int position = annotationp.position();
            String columnName = annotation.column();
            headers.add(position,columnName);
        }
    }
    return headers.toArray(new String[0]);
}  

//写入csv文件

private void writeObjectsToCsv(List objList, String savePath) {
    String[] customHeader = getHeader
