簡單記錄一下java讀取excel檔案的小方法。

使用jxl.jar進行讀取，需要注意的是，jxl.jar只能讀取xls格式的excel

Maven引用：

        <dependency>
            <groupId>net.sourceforge.jexcelapi</groupId>
            <artifactId>jxl</artifactId>
             <version>2.5.7</version>
        </dependency
 
> 

方法傳入一個資料夾path，遍歷該資料夾下所有excel檔案，輸出檔案內容到控制檯

    public static void readExcel(String path) throws BiffException, IOException, InterruptedException{
        File file = new File(path);
        if(!file2.getName().endsWith(".xls")){
                continue;
        }
        File[] files = file.listFiles();
        for
 
 (File file2 : files) {
            Sheet sheet = null;
            Workbook book = null;
            book = Workbook.getWorkbook(file2); 
            sheet = book.getSheet(0);
            for(int row = 0; row < sheet.getRows(); row++ ){
                for(int col = 0; col < sheet.getColumns(); col++){
                    String cellText = sheet.getCell(col, row).getContents();
                    if
 
 ("".equals(cellText)) {
                        continue;
                    }
                    System.out.println(cellText);
                }
            }
        }
    }

    public static void main(String[] args) throws BiffException, IOException, InterruptedException {
        readExcel("C:\\Users\\path");
    }
