</body>
</html>
首先index.html中的标签添加id

【问题】人气旅游不显示&选中格式也错位了

【原因】选中发现“人气旅游”是存在的，只是字体颜色和背景色都是白色所以看不见

index.html

改之前

<div class="jx_tit">
        <img src="images/icon_5.jpg" alt="">
        <span>黑马精选</span>
    </div>
    <!-- Nav tabs -->
    <ul class="jx_tabs" role="tablist">
        <li role="presentation" class="active">
            <span></span>
            <a href="#popularity" aria-controls="popularity" role="tab" data-toggle="tab">人气旅游</a>
        </li>
        <li role="presentation">
            <span></span>
            <a href="#newest" aria-controls="newest" role="tab" data-toggle="tab">最新旅游</a>
        </li>
        <li role="presentation">
            <span></span>
            <a href="#theme" aria-controls="theme" role="tab" data-toggle="tab">主题旅游</a>
        </li>
    </ul>
</div>

改之后

<div class="jx_tit">
        <img src="images/icon_5.jpg" alt="">
        <span>黑马精选</span>
    </div>
    <!-- Nav tabs -->
    <ul class="jx_tabs" role="tablist">
        <li role="presentation" class="active">
            <a href="#popularity" aria-controls="popularity" role="tab" data-toggle="tab">人气旅游</a>
            <span></span>
             </li>
        <li role="presentation">
            <a href="#newest" aria-controls="newest" role="tab" data-toggle="tab">最新旅游</a>
            <span></span>
           </li>
        <li role="presentation">
            <a href="#theme" aria-controls="theme" role="tab" data-toggle="tab">主题旅游</a>
            <span></span>
        </li>
    </ul>
</div>

修改之后即可

【出现报错】

前端是404，找不到/travel/css/bootstrap.min.css.map

解决方法见：http://t.csdn.cn/dockY

导入了/travel/css/bootstrap.min.css，但是一直404，找不到/travel/css/bootstrap.min.css.map，找不到对应的路径（真没有.map这个文件啊），怪哉！

后台报的是testWhileIdle is true, validationQuery not set

浏览器访问Maven项目时报testWhileIdle is true, validationQuery not set

原因：

开启空闲检测，但是没有设置对应的检测语句

解决方法

在druid配置文件加上

#如果指定,则查询必须是一个SQL SELECT并且必须返回至少一行记录 
 validation-query: select 1

好像没什么用￣□￣｜｜

【出现问题】人气旅游分页没有内容展示

【原因】RouteDaoImpl中查询语句返回有误，

更正一下

前端页面展示

【问题】但是一看，最新旅游和主题旅游还是写死的界面

【出现原因】index.html中id选择器没有对应id

加上以后运行结果：

成了鸭，好耶！
