SpringMVC上传文件

效果如下

需要新加入的jar包：commons-fileupload-1.3.3.jar，commons-io-2.5.jar

 

    <form action="upload" enctype="multipart/form-data" method="post">
          <table>
              <tr>
                  <td>文件描述</td>
                  <td><input type="text" name="description"></td>
              </tr>
              <tr>
                  <td>请选择文件</td>
                  <td><input type="file" name="file"></td>
              </tr>
              <tr>
                  <td><input type="submit" value="上传"></td>
              </tr>
          </table>
      </form>
