spring项目中遇到的问题

获取span中value参数的值

$(this).find('.glyphicon').attr('value')

输入为大于0的数的正则表达式

 var re=/^(0\.[0-9]\d*|[1-9]\d*(\.\d+)?)$/;  if (!re.test($("input[name='currencyRate']").val().trim())){  $.growlUI('提示', '输入格式不对');  return false;    }

jsp中进行调试 debugger;

mysql主键自动增加

 <insert id="insert" useGeneratedKeys="true" keyProperty="id" parameterType="com.pandaw.model.CouponItem">    <!--      WARNING - @mbggenerated      This element is automatically generated by MyBatis Generator, do not modify.      This element was generated on Mon Sep 22 12:02:47 CST 2014.    -->    insert into coupon_item (id, title, value,       type, rule, start_time,       end_time)    values (#{id,jdbcType=INTEGER}, #{title,jdbcType=VARCHAR}, #{value,jdbcType=INTEGER},       #{type,jdbcType=VARCHAR}, #{rule,jdbcType=VARCHAR}, #{startTime,jdbcType=TIMESTAMP},       #{endTime,jdbcType=TIMESTAMP})  </insert>

日期字符串在jsp中进行比较

<td>   <c:set var="nowDate" value="<%=System.currentTimeMillis()%>"></c:set>                                        <c:if test="${nowDate -couponItem.endTime.time < 0 && nowDate -couponItem.startTime.time>0 }">    进行中</c:if>  <c:if test="${nowDate- couponItem.endTime.time > 0}"> 已结束</c:if>  <c:if test="${nowDate-couponItem.startTime.time < 0}"> 未开始</c:if>  </td>

ajax应用

jsp中的js

    $.ajax({  type:'post',  url:'${contextPath}/wx/order/verifyScores',  data:{  scoresNum:scoresText  },  success:function(data){  if(data.status == 1){  $('#addtoScores').modal('hide');  $('#scoresPrice').text(data.data);  $('#defineFont1').text(data.data);  var p = $('#realPriceHidden').val()*100 - $('#defineFont').text()*100 - $('#defineFont1').text()*100;  p/=100;  if(p < 0){  p = 0;  }  $('#realPriceFont').text(p);      //$('#defineScores').modal();  }else if(data.status == 2){  $('#addtoScores').modal('hide');  alert('积分不足');  }else if(data.status == 3){  alert('该优惠卷未开始');  }else if(data.status == 4){  alert('该优惠卷已过期');  }else if(data.status == 5){  alert('该优惠卷已使用');  }  },  error:function(){  alert('网络连接超时1');  }  });   });

java控制代码

@SuppressWarnings("unchecked")@RequestMapping(value = "/verifyScores")@ResponseBodypublic Map<String,Object> verifyScores(@RequestParam String scoresNum,@OpenId String openId) throws Exception{Map<String, Object> res = new HashMap<String, Object>();res.put("status", 1);res.put("data", WxUtil.scoreToMoney(Integer.parseInt(scoresNum)));  User2 user = new User2();          user=user2Service.selectByOpenId(openId);         if(Integer.parseInt(scoresNum)>user.getScore()){         res.put("status", 2);//积分不足         }return res;}
