使用jquery异步上传文件的操作

我想使用jQuery异步上传文件.这是我的HTML:

<input type="file" id="f" name="f"/>
<input id="upload" type="button" value="Upload"/>

在这里我的JavaScript代码:

$(document).ready(function () {
$("#upload").click(function () {
    var filename = $("#f").val();

    $.ajax({
        type: "POST",
        url: "addFile.do",
        enctype: 'multipart/form-data',
        data: {
            file: filename
        },
        success: function () {
            alert("All Files Have Been Uploaded ");
        }
    });
});
});

我只获取文件名而不是我上传的实际文件

我正在使用此插件上传文件.

RabbitMQ 无法声明队列并且侦听器无法在服务器上获取队列

我有spring boot rabbitmq应用程序，我必须将 Employee 对象发送到队列中。然后我设置了一个监听器应用程序。对员工对象进行一些处理并将此对象放入回调队列中。

为此，我在我的应用程序中创建了以下对象。

  1. 创建了ConnectionFactory。
  2. 使用ConnectionFactory创建了RabbitAdmin对象。
  3. 请求队列。
  4. 回调队列。
  5. 直接交换。
  6. 请求队列绑定。
  7. 回调队列绑定。
  8. 消息转换器。
  9. RabbitTemplate 对象。
  10. 最后是SimpleMessageListenerContainer 的对象。

我的应用程序文件如下所示。

spring.rabbitmq.host=localhost
spring.rabbitmq.port=5672

spring.rabbitmq.password=guest

我正在错误以下。

错误

下面我尝试过的东西。

  1. 更新Maven项目
  2. 项目清理与建设
  3. 检查是否配置了正确的Java版本。

我仍然无法解决这个问题。任何帮助表示赞赏。

Mysql之间的查询无法正常工作

我正在使用mysql.我想在两个日期之间显示记录.我在网上搜索,发现mysql的日期格式是yyyy/mm/dd.所以我写的查询如下,

select 
    * 
from tbl_reservation 
where 
    current_date between '2014-03-28' and '2014-03-26';
Run Code Online (Sandbox Code Playgroud)

但是,我不知道它为什么不起作用."col_date"具有DATE数据类型.我不是在里面存放时间.

让我告诉你我在后端做了些什么,

SimpleDateFormat sdf=new SimpleDateFormat("yyyy-MM-dd");
Date curr_date=new Date();
String compareDate=sdf.format(curr_date);
Run Code Online (Sandbox Code Playgroud)

我将此值存储在"col_date"中.它是否因为这种处理而发生？

感谢您提前宝贵的时间.

Spring boot：创建名为“methodValidationPostProcessor”的bean时出错
