提示:这里描述项目中遇到的问题:
在某个项目中添加按钮一直显示执行出错
一开始想的是代码问题,于是翻看各层代码:
首先看页面:
<script> layui.use(['form', 'upload', 'laydate'] ,function(){ var form = layui.form ,$ = layui.jquery ,layer = layui.layer ,upload = layui.upload ,laydate = layui.laydate; //日期 laydate.render({ elem: '#date' }); //普通图片上传 var uploadInst = upload.render({ elem: '#test1' ,url: '/uploadFile' ,before: function(obj){ //预读本地文件示例,不支持ie8 obj.preview(function(index, file, result){ $('#demo1').attr('src', result); //图片链接(base64) }); } ,done: function(res){ //如果上传失败 if(res.code > 0){ return layer.msg('上传失败'); } //上传成功 return layer.msg('上传成功'); } ,error: function(){ //演示失败状态,并实现重传 var demoText = $('#demoText'); demoText.html('<span >上传失败</span> <a class="layui-btn layui-btn-xs demo-reload">重试</a>'); demoText.find('.demo-reload').on('click', function(){ uploadInst.upload(); }); } }); //监听提交 form.on('submit(setmyinfo)', function(obj){ $.ajax({ type: "POST", url: "/hotel", data: JSON.stringify(obj.field), dataType: "json", contentType: "application/json;charset=utf-8", success: function(result) { if(result.code == 0) { //登入成功的提示 layer.msg( result.message,{ icon: 1 }); } else { layer.msg(result.message, { icon: 5 }); } } }); }); }); </script>
Controller层代码
/** * 增加 * @param hotel */ @ResponseBody @RequestMapping(method=RequestMethod.POST) public Result add(@RequestBody Hotel hotel){ hotelService.add(hotel); return new Result(true,StatusCode.OK,"增加成功"); }
Dao层数据访问接口
public interface HotelDao extends JpaRepository<Hotel,String>,JpaSpecificationExecutor<Hotel>{ List<Hotel> findByAddrLike(String addr); }
Service层代码
/** * 增加 * @param hotel */ public void add(Hotel hotel) { hotel.setId( idWorker.nextId()+"" ); //取到缓存中的文件url String fileurl = (String) redisTemplate.opsForValue().get("fileurl"); hotel.setImg("https://travel031.oss-cn-qingdao.aliyuncs.com/"+fileurl); hotelDao.save(hotel); }
其实这一路看过来没发现啥问题,基本上是谁也不会觉得代码有问题
提示:Unable to connect to Redis
这意思是说无法连接到Redis
当时是看完代码觉得没问题又去F12检查页面,当然我还是没看出啥问题????
提示:缺少Redis环境
最后运行成功!
在管理员后台列表中也可以看到数据
以上是Unable to connect to Redis無法連結到Redis如何解決的詳細內容。更多資訊請關注PHP中文網其他相關文章!
