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
以上がRedis に接続できない Redis に接続できない問題の解決方法の詳細内容です。詳細については、PHP 中国語 Web サイトの他の関連記事を参照してください。
