SpringBoot导入excle文件数据

本文主要描述，Springboot框架下上传excel，处理里面相关数据做逻辑分析，由于用到的是前后端分离技术，这里记录的主要是后端java部分，通过与前端接口进行对接实现功能

1.在pom.xml文件中导入注解，主要利用POI

<dependency>
      <groupId>org.apache.poi</groupId>
      <artifactId>poi-ooxml</artifactId>
      <version>3.9</version>
</dependency>
<dependency>
      <groupId>commons-fileupload</groupId>
      <artifactId>commons-fileupload</artifactId>
      <version>1.3.1</version>
</dependency>
<dependency>
      <groupId>commons-io</groupId>
      <artifactId>commons-io</artifactId>
      <version>2.4</version>
</dependency>

2. springboot java实现代码

@RequestMapping(value="/uploadTest", method = RequestMethod.POST)
    public String uploadTest(@RequestParam MultipartFile file, HttpServletRequest request){

        try {
            if(file==null)
                return BaseCode.retCode(1, "上传文件不能为空").toString();
            String fileName = file.getOriginalFilename();
            if (!fileName.matches("^.+\.(?i)(xls)$") && !fileName.matches("^.+\.(?i)(xlsx)$")) {
                return BaseCode.retCode(1, "上传文件格式错误，请上传后缀为.xls或.xlsx的文件").toString();
            }

            boolean isExcel2003 = true;
            if (fileName.matches("^.+\.(?i)(xlsx)$")) {
                isExcel2003 = false;
            }
            InputStream is = file.getInputStream();
            Workbook wb = null;
            if (isExcel2003) {
                wb = new HSSFWorkbook(is);
            } else {
                wb = new XSSFWorkbook(is);
            }
            Sheet sheet = wb.getSheetAt(0);
            if(sheet!=null){
                //notNull = true;
            }
            for (int r = 1; r <= sheet.getLastRowNum(); r++) {
                Row row = sheet.getRow(r);
                if (row == null) {
                    continue;
                }
               

　　　　System.out.println(row.getCell(0).getStringCellValue());

 } 
} catch (IOException e) {
}
 return BaseCode.retCode(ResultCode.success).toString(); 
}
