跟踪字段发现原来是下拉框<option>中参数赋值错误导致，详见如下：
原来的html:
<select id="checkResult" name="checkResult">
<option value="">全部</option>
<option value="0">不存在</option>
<option value="1">已存在</option>
</select>
后台用的是mybatis，而对应的vo中定义的checkResult是long类型，所以导致把空字符串赋值给long类型的checkResult时发生了如上的异常，修改如下：
<select id="checkResult" name="checkResult">
<option value="-1">全部</option>
<option value="0">不存在</option>
<option value="1">已存在</option>
</select>
