java读取excel文件,用jxl包,列的名称不固定怎么办?

etc

处理列名不固定的情况可以通过使用workbook对象的列标签来实现。首先，我们需要获取到workbook对象，并创建一个worksheet对象。然后，使用worksheet对象的getcolumn标签来获取到列标签，最后将列标签赋值给变量即可。以下是一个示例代码片段：Javaimport org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataFormat;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;import org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataFormat;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;import org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;import org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;//读取excel文件import org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;import org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;//读取excel文件import org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;//读取excel文件import org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;//读取excel文件import org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;//读取excel文件import org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;//读取excel文件import org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;//读取excel文件import org.apache.poi.xssf.usermodel.XSSFCellStyle;import org.apache.poi.xssf.usermodel.XSSFDataValidationSequence;import org.apache.poi.xssf.usermodel.XSSFDataValidationRule;import org.apache.poi.xssf.usermodel.XSSFFont;import org.apache.poi.xssf.usermodel.XSSFRange;import org.apache.poi.xssf.usermodel.XSSFRow;//读取excel文件import org.apache.poi.xssf.usermodel.XSSFCellStyle;...
