将Excel文件表导入到java时出错
我想创build一个双数组中的值从两列在Java中，它不认可我的工作表。
我认为我的path名称可能是问题，除了这是从目录复制和粘贴。 （除了额外的斜线当然）。 任何在这个方向的指针都会有所帮助。
这是我的代码：
“XSSFWorkbook workbook = new XSSFWorkbook（fis）”引发exception。
package adina.twitter; import java.io.IOException; import java.util.Iterator; import java.io.File; import java.io.FileInputStream; import org.apache.poi.ss.usermodel.Cell; import org.apache.poi.ss.usermodel.Row; import org.apache.poi.xssf.usermodel.XSSFCell; import org.apache.poi.xssf.usermodel.XSSFRow; import org.apache.poi.xssf.usermodel.XSSFSheet; import org.apache.poi.xssf.usermodel.XSSFWorkbook; import java.lang.Iterable; public class ReadFile { public static void main(String[] args) throws IOException { final String FILE_PATH = "C:\\Users\\silbeab1\\Documents\\seedsActivity12Junv2.xlsx"; String fileSheet = "screen_name-user_id"; String[][] snId = null; try{ FileInputStream fis = new FileInputStream(new File(FILE_PATH)); XSSFWorkbook workbook = new XSSFWorkbook(fis); XSSFSheet worksheet = workbook.getSheet(fileSheet); boolean flag = true; System.out.println(flag); for (int x = 0; flag == true; x++){ for (int y = 0; y < 2; y++){ String test = worksheet.getRow(x).getCell(y).toString(); if (test != null){ snId[x][y] = test; } else{ flag = false; } } } } catch (Exception e){ System.out.printf("Cannot open %s \n error: %s",FILE_PATH,e); } } } 这里是我的输出：无法打开C：\ Users \ silbeab1 \ Documents \ seedsActivity12Junv2.xlsx错误：org.apache.poi.POIXMLException：java.lang.reflect.InvocationTargetException
这是完整的堆栈跟踪：

这个exceptionjava.io.CharConversionException: Characters larger than 4 bytes are not supported: byte 0xa6 implies a length of more than 4 bytes （在apache-poi的情况下）当你尝试读取一个.xlsb格式（这不是支持的）。
你确定你的Excel是xlsx格式，而不是xlsb格式吗？
请参阅以下链接，了解类似的例外情况，但仅限于xlsb格式： http ://comments.gmane.org/gmane.comp.jakarta.poi.user/12151
