业务需求：
批量插入/更新HAP_DEMO表练习
以下为实现功能的要点：
1. 要求使用队列方式实现
2. 在Demo⻚面新增按钮，⽤于启动列息的发送
3. 一次性向队列中推送1000条消息，消息内容为 DEMO 记录的ID
4. 消息队列的名称： wht:<部⻔门简称:<⼯工号>:demo , 例如 wht:ora:2062:demo
5. 队列的消费者接收到DEMO的ID，随机更新ID对应的Name值，可参考之前的定时任务的逻辑。
6. 消费者在处理前使用 Thread.sleep ⽅法模拟处理时长为30s的任务；
-
ora20796_deml.html先增加一个按钮：注意data-bind="click:startMessageQueue"拼写
启动队列消息
url: '${base.contextPath}/ora/20796/hap/demo/send/mq',这个要和控制类里面的路径对应
/**
*启动消息队列
*/
startMessageQueue:function(){
alert("启动消息队列")
///hap/demo/send/mq
$.ajax({
url: '${base.contextPath}/ora/20796/hap/demo/send/mq',
type: 'POST',
dataType: "json",
contentType: "application/json",
success: function (result) {
if(result.success){
kendo.ui.showInfoDialog({
title: $l('hap.tip.info'),
message: $l("hap.success")
});
viewModel.query();
} else {
kendo.ui.showErrorDialog({
title: $l('hap.error'),
message : result.message
});
}
}
});
},
