1. 自己项目学习中要用到上传视频功能，博主也遇到很多问题，查询了很多资料才将就着写完了部份代码，后续持续更新。。。。。新手写csdn可能不太好看。。体谅一下
2. 开始我的代码表演！
1.前端页面代码如下：
图片和视频的上传我都是设置了不立即上传，当点击添加视频信息的时候才和表单数据一起上传到后台操作。

 <div style="height: 130px;width:100%;border:1px solid rgba(56,166,255,.1);box-shadow: 0 0 8px #ccc;background-color: white;margin-top: -10px">
     <el-form :model="ruleForm"  ref="ruleForm" label-width="100px" class="demo-ruleForm">
         <div class="demo-input-suffix" style="margin-top: 20px;float: left;padding-left: 10px;">
             <el-span style="font-size: 18px">名称：</el-span>
             <el-input style="width: 130px;"
                       placeholder="请输入视频名称"
                       v-model="ruleForm.name" @keyup.enter.native="onEnterSearch">
                 <i slot="prefix" class="el-input__icon el-icon-search"></i>
             </el-input>
             <el-span style="font-size: 18px;margin-left: 15px;">类别：</el-span>
             <el-select v-model="ruleForm.type" placeholder="请选择类别" style="width: 130px;" >
                 <el-option
                         v-for="item in options"
                         :key="item.value"
                         :label="item.label"
                         :value="item.value">
                 </el-option>
             </el-select>
             <el-span style="font-size: 18px;margin-left: 15px;"> 状态：</el-span>
             <el-select v-model="ruleForm.status" placeholder="请选择状态" style="width: 130px;">

                         v-for="item in status"
                         :key="item.value"
                         :label="item.label"
                         :value="item.value">
                 </el-option>
             </el-select>
             <el-span style="font-size: 18px;margin-left: 15px;"> 开始日期：</el-span>

                    }
                    vm.loading = true;
                    //封装表单数据传到后台
                    vm.formObj.append("videoName",vm.formData.videoName);

                    vm.formObj.append("file",vm.formData.file);
                    console.log(vm.formObj)
                    $.ajax({
                        url: '/file/upload',
                        data: vm.formObj,
                        type: 'POST',
                        dataType: 'json',
                        cache: false,
                        processData: false,
                        contentType: false,
                        success: function (data) {
                            vm.loading = false;
                        },
                        error:function () {
                            vm.loading = false;
                            vm.$message.error("添加失败！！")
                        }
                    });
                } else {
                    console.log('error submit!!');
                    return false;
                }
            });
        }
    }

3.后台接收ajax传递的数据，后面保存在mongodb详细代码还没写完，这里先展示接收收据的代码。。

/**
	 * 上传文件
	 *
	 * @param file
	 * @return
	 * @throws IOException
	 * @throws ServletException
	 */
	@ApiOperation(value = "上传文件测试", notes = "上传文件测试")
	@PostMapping(value="/upload",produces = "application/json")
	@ResponseBody
	public ResultForm uploadFile(@RequestParam("videoName")String videoName,@RequestParam("videoType")String videoType,@RequestParam("videoTimes")String videoTimes,
								 @RequestParam("videoJj")String videoJj,@RequestParam("videoStatus")String videoStatus,@RequestParam("file") MultipartFile[] file) throws IOException, ServletException {
		// 获得提交的文件名
		String fileName = file[0].getOriginalFilename();
		// 获取文件输入流
		InputStream ins = file[0].getInputStream();
		// 获取文件类型
		String contentType = file[0].getContentType();
		// 将文件存储到mongodb中
		ObjectId objectId = gridFsTemplate.store(ins, fileName, contentType);
		logger.info("保存成功，objectId:" + objectId);
		return new ResultForm(true,"上传成功");
	}

4.由于使用的是springboot内置的tomcat，所以上传文件大小超过1M页面都会报错，所以必须修改内置tomcat的限制，只需在配置文件修改即可，代码如下

#设置springboot的内置tomcat上传文件大小
#配置文件传输
spring.servlet.multipart.enabled =true  
spring.servlet.multipart.file-size-threshold =0
#单个数据的大小
spring.servlet.multipart.max-file-size = 100MB
#总数据的大小
spring.servlet.multipart.max-request-size=100MB

修改完后就可以上传视频文件了！！！！！
5.最后贴出代码运行截图。。。个人项目希望各位大佬多多给小弟提建议
点击添加视频按钮后上传视频信息
点击理解添加后
