格式化bean生成器的頭字段 - Java

Question

我已經編寫了一個程序，用於解析csv文件，並根據要放入數據庫的數據創建一個bean。一切都很完美，但現在它將被移出測試環境，csv的真實標題名稱將不得不被添加。這些標題包含空格和/。我正在尋找一種方法來讓我的解析器讀取這些頭文件。當我定義標題名稱時，我必須使用camelCasing，並且我無法插入空格或其他字符。無論如何改變這個？

這裏是我的構造函數（integrationTeam必須整合團隊，softwareHardware需要在硬件/軟件 - 這是在CSV標題）

public class BeanGen { 

public BeanGen(
    final String name, 
    final String manufacturer, 
    final String model, 
    final String owner, 
    final String integrationTeam, 
    final String shipping, 
    final String hardwareSoftware, 
    final String subsystem,      
    final String plane, 
    final String integrationStandalone, 
    final String integrationInterface, 
    final String function, 
    final String helpLinks, 
    final String installationInstructions, 
    final String testSteps, 
    final String leadEngineer) 
    { 
    this.name = name; 
    this.manufacturer = manufacturer; 
    this.model = model; 
    this.owner = owner; 
    this.integrationTeam = integrationTeam; 
    this.shipping = shipping; 
    this.hardwareSoftware = hardwareSoftware; 
    this.subsystem = subsystem; 
    this.plane = plane; 
    this.integrationStandalone = integrationStandalone; 
    this.integrationInterface = integrationInterface; 
    this.function = function; 
    this.helpLinks = helpLinks; 
    this.installationInstructions = installationInstructions; 
    this.testSteps = testSteps; 
    this.leadEngineer = leadEngineer; 
    } 

這裏是處理構造

public class ParseHandler { 

private static CellProcessor[] getProcessors() { 

    final CellProcessor[] processors = new CellProcessor[] { 

      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
      new Optional(), 
    }; 
    return processors; 
} 

public static BeanGen readWithCsvBeanReader(Path path) throws IOException { 
    ICsvBeanReader beanReader = null; 
    BeanGen projectBean = null; 
    System.out.println("Processing File: " + path); 
    try { 
     beanReader = new CsvBeanReader(new FileReader(path.toString()), CsvPreference.STANDARD_PREFERENCE); 
     // the header elements are used to map the values to the bean (names 
     // must match) 
     final String[] header = beanReader.getHeader(true); 
     final CellProcessor[] processors = getProcessors(); 

     if ((projectBean = beanReader.read(BeanGen.class, header, processors)) != null) { 
      System.out.println(String.format("%s", projectBean.toString())); 
     } 
    } finally { 
     if (beanReader != null) { 
      beanReader.close(); 
     } 
    } return projectBean; 
} 
}

Answer 1

見Super CSV documentation，部分與CsvBeanReader閱讀：

這取決於CSV文件標題中的列名與bean的字段名完全匹配，並且該bean具有爲每個字段定義的相應setter。 如果你的頭不匹配（或沒有頭），那麼你可以簡單地定義你自己的名稱映射數組。

您讀取標題並將其作爲第二個參數傳遞給beanReader.read()。但根據API reference第二個參數是一個包含bean屬性名稱的字符串數組。所以你應該通過類似

new String[] { "name", "manufacturer", "model", "owner", "integrationTeam", ... } 

作爲第二個參數。因此，第一個CSV列與豆田name匹配，第二個字段與豆田manufacturer等匹配。
