根据这篇关于abilities of SuperCSV的帖子,SuperCSV可以处理从数据库中读取的标题(仅 列名 )的值吗?
例如,以下代码段详细说明了当前状态和预期状态。
INPUT :
final String[] header = new String[] { "firstName", "lastName", "birthDate"};
// write the header
beanWriter.writeHeader(header);
// write the beans
for( final CustomerBean customer : customers ) {
beanWriter.write(customer, header, processors);
}
OUTPUT :包含列名称的文件:
firstName, lastName, birthDate
Bob , Doe , 02/12/2013
INPUT :
final String[] header = new String[] { "firstName", "lastName", "birthDate"};
// write the header
beanWriter.writeHeader(header);
// write the beans
for( final CustomerBean customer : customers ) {
beanWriter.write(customer, header, processors);
}
// modify the headers
??????
OUTPUT :包含已修改列名称的文件:
First Name, Last Name, Birthday
Bob , Doe , 02/12/2013
非常感谢任何帮助。

我不确定这是否能回答您的问题,但您可以在标题中添加您喜欢的内容 - 它不必与传递给beanWriter.write()
的映射数组相同
例如,以下内容将提供您想要的输出:
final String[] header = new String[] { "First Name", "Last Name", "Birthday"};
final String[] fieldMapping = new String[] { "firstName", "lastName", "birthDate"};
// write the header
beanWriter.writeHeader(header);
// write the beans
for( final CustomerBean customer : customers ) {
beanWriter.write(customer, fieldMapping , processors);
}
