今天完成的事情：

点赞收藏接口新增数据总是报错，排查之后发现判空没有执行

@RequestMapping(value = "/a/u/collect-like/{targetId}",method = RequestMethod.PUT)
public String userAction(HttpServletRequest request,HttpServletResponse response,ModelMap model,@PathVariable Long targetId,Long userId,Integer targetType,
                         Integer relationType,Integer status)throws Exception{
    log.info("入参targetId"+targetId+"userId"+userId+"targetType"+targetType+"relationType"+relationType+"status"+status);
    try {
        if (relationType == null || targetId == null || targetType == null || userId == null || status == null){
            model.addAttribute("code",-1000);
            return "data/json";
        }else {
            Map<String,Object> param= DynamicUtil.userActionParam(userId, targetId, relationType,targetType);
            log.info("param为"+param);
            List<Long> ids=praiseCollectionService.getIdsByDynamicCondition(PraiseCollection.class,param,0,1);
            log.info("ids为"+ids);
            if (ids == null){
                PraiseCollection praiseCollection1=new PraiseCollection();
                praiseCollection1.setUserId(userId);
                praiseCollection1.setTargetId(targetId);
                praiseCollection1.setTargetType(targetType);
                praiseCollection1.setRelationType(relationType);
                praiseCollection1.setStatus(status);
                praiseCollectionService.insert(praiseCollection1);
                log.info("新增的praiseCollection为"+praiseCollection1);
                model.addAttribute("code",0);
                return "data/json";
            }else {
                PraiseCollection praiseCollection=praiseCollectionService.getObjectById(ids.get(0));
                praiseCollection.setStatus(status);
                log.info("修改之后的praiseCollection为"+praiseCollection);
                praiseCollectionService.update(praiseCollection);
                model.addAttribute("code",0);
            }
        }
    }catch (Throwable t){
        t.printStackTrace();
        log.error(t.getMessage());
        log.error("点赞收藏错误");
        model.addAttribute("code",-1);
    }
    return "data/json";
}

ids是个list，不能 == null这样判断，这是在判断对象存不存在

应该用这种

if (ids.isEmpty())

或者

if (ids.size() == 0)

改完之后接口通了

公司框架impl里的insert和updat方法自带更新create_at和update_at，不用自己在controller里写

明天计划的事情：

服务器上跑一跑
