JAVA实现按时间段查询数据操作

html / jsp

<span style="vertical-align: -webkit-baseline-middle;font-size:16px;font-weight:bold;">开始时间：</span>&nbsp;
<input name="startTime" id="startTime" type="text" class="Wdate" onfocus="WdatePicker()" style="height: 34px;
 line-height: 34px; border-radius: 4px; border: 1px solid #ccc; font-size: 14px;">
<span class="ml10 mr8" style="font-size:16px;font-weight:bold;">结束时间：&nbsp;</span>
<input name="endTime" id="endTime" type="text" class="Wdate" onfocus="WdatePicker()" style="height: 34px;
 line-height: 34px; border-radius: 4px; border: 1px solid #ccc; font-size: 14px;">
<input type="submit" class="btn btn-query" id="findTime" value="查询" onClick="toFindTime();" style="float:none;"/>

js方法：

function timeCheckInfo(page,startTime,endTime,officeVal){
 var startTime=$("#startTime").val();
 var endTime=$("#endTime").val();
 $.ajax({
 url: "../../security/base/peoplesafeimg!findPortFolioByTime.action",
 type: "post",
 data:{
  pagenum:page,
  startTime:startTime,
  endTime:endTime,
  deptid:officeid, // 处室ID来源于默认(页面传值)和下拉框选择 lenian 2018 06 29
  depotid:depotid
 },
 dataType: "json",
 success: function (data) {
  //alert(JSON.stringify(data));
  var dataset = data[0].result;
  $(dataset).each(function(i,val) {

  });
 },
 error:function(){
  alert("查询数据失败")
 }
 });
}

补充知识：Java 实现判断时间是否在某个区间内（如是否在23点到凌晨4点之间）

最近遇到一个需求，就是判断一个时间是否在23点到凌晨4点之间，这个时间段是可以修改的。在网上收了一下发现没有符合我的需求的，就自己琢磨了一下，感觉这样算还是可以的。

思路：

如上图的那个圆形的钟表，可以从开始时间剪断，把钟表的环铺平，此时就变成了一个刻度尺，这样就好比较了

代码块

测试代码：

public static void main(String[] args) {
  int start = 23;
  int end = 4;

  int emp = 24 - start;

  for (int d = 0; d < 24; d++) {
    System.out.println((start + emp) % 24 + "\t" + (d + emp) % 24 + "\t" + (end + emp) % 24);
  }
}

输出：

0 1 5
0 2 5
0 3 5
0 4 5
0 5 5
0 6 5
0 7 5
0 8 5
0 9 5
0 10 5
0 11 5
0 12 5
0 13 5
0 14 5
0 15 5
0 16 5
0 17 5
0 18 5
0 19 5
0 20 5
0 21 5
0 22 5
0 23 5
0 0 5
