java - 使用 SuperCSV 更改 header 值

Question

符合这个帖子关于abilities of SuperCSV , SuperCSV 能否处理更改从数据库读取的标题(仅列名)的值？

例如，以下代码片段详细说明了当前状态和预期状态。

当前状态

输入:

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:包含列名的文件:

firstName, lastName, birthDate
Bob      , Doe     , 02/12/2013  

预期状态

输入:

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
 ??????

输出:具有修改列名称的文件:

First Name, Last Name, Birthday
Bob      , Doe     , 02/12/2013 

非常感谢任何帮助。

我不确定这是否回答了您的问题，但您可以在 header 中放置您喜欢的任何内容 - 它不必与传递给 beanWriter.write()

例如，以下将给出您想要的输出:

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);
}
