关于个人的使用经验：先把数据放到bean中，多个的话就全放入list集合，如下代码：
/*
     * 把图片信息写入taichi本地数据库
     * 参数样例：
     *  {
            "paramList": [{
                    "serviceOrderName": "服务单号",
                    "serviceOrderId": "服务单id",
                    "supplierId": "供应商id",
                    "classifyId": 5,
                    "imageUrlList": [
                        "url1",
                        "url2",
                        "url3"
                    ]
                },
                {
                    "serviceOrderName": "服务单号2",
                    "serviceOrderId": "服务单id2",
                    "supplierId": "供应商id2",
                    "classifyId": 5,
                    "imageUrlList": [
                        "2url1",
                        "2url2",
                        "2url3"
                    ]
                }
            ]
        }
     */
    @RequestMapping(value = "/image/writeImageInfo", method = RequestMethod.POST)
    public ResponseWrapper<Object> writeImageInfo( @RequestBody WriteImageDTO WriteImageDTO){
        ResponseWrapper<Object> returnResult = new ResponseWrapper<Object>();
        List<ImageInfoForWriteDataBase> paramList = WriteImageDTO.getParamList();
        if(paramList == null || paramList.size() < 1){
            log.info("图片信息入库参数为空");
            returnResult.setSuccess(false);
            returnResult.setMsg("图片信息入库参数为空");
            return returnResult;
        }
        try{
            List<ImageInfoDTO> tempParamList = new LinkedList<ImageInfoDTO>();
            for (ImageInfoForWriteDataBase imageInfoForWriteDataBase : paramList) {
                List<String> imageUrlList = imageInfoForWriteDataBase.getImageUrlList();
                for (String stringObj : imageUrlList) {
                    ImageInfoDTO obj = new ImageInfoDTO();
                    obj.setServiceOrderName(imageInfoForWriteDataBase.getServiceOrderName());
                    obj.setServiceOrderId(imageInfoForWriteDataBase.getServiceOrderId());
                    obj.setSupplierId(imageInfoForWriteDataBase.getSupplierId());
                    obj.setClassifyId(imageInfoForWriteDataBase.getClassifyId());
                    obj.setClassifyName(ImageClassifyEnum.getNameStatic(imageInfoForWriteDataBase.getClassifyId()));
                    obj.setImageUrl(stringObj);
                    tempParamList.add(obj);
                }
            }

            Integer result = partsService.writeImageInfo(tempParamList);//数据入库
            if(result > 0){
                returnResult.setSuccess(true);
                return returnResult;
            }else{
                returnResult.setSuccess(false);
                returnResult.setMsg("图片信息入库失败");
                return returnResult;
            }
        }catch(Exception e){
            log.info("图片信息入库异常,==>e.getMessage:"+e.getMessage()+",==>e.getStackTrace():"+e.getStackTrace()+",==>e:"+e);
            returnResult.setSuccess(false);
            returnResult.setMsg("图片信息入库异常");
        }
        return returnResult;
    }

public Integer writeImageInfo(List<ImageInfoDTO> tempParamList){
        return operateTaichiDao.writeImageInfo(tempParamList);
    }

Integer writeImageInfo(List<ImageInfoDTO> tempParamList);

<insert id ="writeImageInfo" parameterType="java.util.List">
         insert into imageinfo
         (serviceOrderName, serviceOrderId, supplierId, classifyId,classifyName,imageUrl)
         values
          <foreach collection ="list" item="node" index= "index" separator =",">
              (
                  #{node.serviceOrderName},
                  #{node.serviceOrderId},
                  #{node.supplierId},
                  #{node.classifyId},
                  #{node.classifyName},
                  #{node.imageUrl}
              )
          </foreach>
   </insert >

注意：上面sql中collection = 一定要写成list，刚开始我写的是参数的名字tempParamList，会报错说站不到参数集合tempParamList，刚开始我还以为是上面文章中的作者写错了。尴尬。

另外，关于传入list数据作为查询条件的sql代码也一并放在这：
dao层代码：
 List<OperateTaskCard> getServiceOrderAlreadyList(@Param("statusNumberList") List<String> statusNumberList,
                                        @Param("newSrvWorkerId") String newSrvWorkerId);
 mapper.xml中的对应的部分sql:
and  new_srv_workorder.new_dealstatus in
<foreach collection="statusNumberList" index="index" item="statusNum" open="(" separator="," close=")">
         #{statusNum}
</foreach>
这里可以看到：collection属性是和参数名字是一样的。
