Answer 1

看看fkpiname是不是action中的接收参数。或者自己把你form表单中的代码java代码去掉。自己做一个固定的试试。例如：
<form action="kpiDayDate.do" method="post">
<select name="fkpiname">
<option value=0>--请选择--</option>
<option value=1>--1--</option>
<option value=2>--2--</option>
</select> <input type="submit" value="查询" /></form>试试这种情况能不能提交

Answer 2

Answer 5

确认下数据库表有没有 character set utf8，request.setCharacterEncoding("utf-8"),response.setContentType("text/html;charset=utf-8"),<%page pageEncoding="utf-8" contentType="text/html;charset=utf-8">
这个地方都可以看下！

Answer 6

你数据库的编码是什么啊？得也是UTF8才行或者改下tomcat的配置文件试试

Answer 7

html页面，action提交的页面 设置的编码一致
记事本打开 另存为 编码 选 与页面设置的编码保持一致。
