Ajax上传.xlsx文件并解析

1、首先必须配置bean

<bean id="multipartResolver"
          class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
        <property name="maxUploadSize" value="10485760"/>
        <property name="resolveLazily" value="true"/>
        <property name="maxInMemorySize" value="4096"/>
        <property name="defaultEncoding" value="UTF-8"/>
    </bean>

2、ftl页面代码

<form id="fileForm" method="post" enctype="multipart/form-data">
        <input type="text" id="someText" name="someText">
        <input type="file" name="file" id="file">
</form>

3、js代码

var someText= $("#someText").val();
var file = $("#file")[0].files[0]; //获取标签值好像函数与浏览器不兼容，网上的大多是通过$("#file").files[0]获取，          
　　　　　　　　　　　　　　　　　　　　　　我这里必须通过$("#file")[0].files[0]才能获取到值　　　　　　　　
var formData = new FormData();　　　　
formData.append('someText', someText);
formData.append('file', file);

$.ajax({
             type:"post",
             url:'请求路径',
             data:formData,
             dataType:'json',
             cache:false,
             contentType: false, 
             processData: false,
             success: function(data) {
         	// 结果处理
         			}
        });    

4、后台代码

@RequestMapping(value = "路径", method = { RequestMethod.GET, RequestMethod.POST })
@ResponseBody
public Object uploadFile(@RequestParam(value = "someText", required = false) String someText, 
@RequestParam(value = "file", required = false) MultipartFile file, 
HttpServletRequest request) {//required = false才能获取到值            
	XSSFWorkbook workbook = new XSSFWorkbook(file.getInputStream());
  XSSFWorkbook workbook = new XSSFWorkbook(file.getInputStream());        
  for (int numSheet = 0; numSheet < workbook.getNumberOfSheets(); numSheet++) {
       XSSFSheet sheetAt = workbook.getSheetAt(numSheet);
       if (sheetAt == null) {
           continue;
           }
       // 循环行Row
       for (int rowNum = 0; rowNum <= sheetAt.getLastRowNum(); rowNum++) {
            XSSFRow row = sheetAt.getRow(rowNum);
            if (row == null) {
                continue;
            }
            // 循环列Cell
　　　　　　for (int cellNum = 0; cellNum <= row.getLastCellNum(); cellNum++) {
　　　　　　　　　　//在此可进行获取单元格值并入库
										getValue(row,cellNum);
　　　　　　　	}
    　　		}
　  	}　　
}   
//单元格类型转换并获取值
private String getValue(XSSFRow row, int cellNum) {
        XSSFCell cell = row.getCell(cellNum);
        if (cell.getCellType() == cell.CELL_TYPE_BOOLEAN) {
            return String.valueOf(cell.getBooleanCellValue());
        } else if (cell.getCellType() == cell.CELL_TYPE_NUMERIC) {
            return String.valueOf((int) cell.getNumericCellValue());
        } else {
            return String.valueOf(cell.getStringCellValue()).equals("") ? "" : String
                    .valueOf(cell.getStringCellValue());
        }
}
