一、html代码                  
 
 <div class="layui-form-item">            <label class="layui-form-label">上传附件：</label>            <div class="layui-input-block doc-litpic">              <button type="button" name="avatar" class="layui-btn layui-btn-sm" data-url="/admin/archives/upload.html" ><i class="layui-icon"></i>本地上传</button>              <a   href=""></a>              <div class="larryms-img-view">              </div>            </div>          </div>
二、js代码      
 
 upload.render({      accept: 'file',      elem: '#larry-litpic',      url: interface_cms_article_upload,      field: 'fileNames',      done : function (res, index, upload) {        if(res.code != 200){          layer.open({            icon : 2,            skin : "layui-layer-molv",            content : res.msg          });        }else{          layer.open({            icon : 1,            skin : "layui-layer-molv",            content : res.msg          });          $('#upload-filename-display').text(res.filename);          $("input[name='fileId']").val(res.filename);        }      },      error : function (res) {      }    });
三、后台controller：
 
@RequestMapping(value = "/upload")  @ApiOperation(value = "本地文件上传",notes ="本地文件上传
