Question

我正在尝试使用JSP / Servlets向后端提交表。

我做了什么：

我已将表数据嵌入表单中。

问题：

我没有将数据发送到后端。（我试图做一个sysout）

我获取了下拉列表的默认值（但不是我选择的值）

代码：

<div class="container">
<form method="POST" action="hello2">
    <div class="row clearfix">
        <div class="col-md-12 table-responsive">
            <table class="table table-bordered table-hover table-sortable" id="tab_logic">
                <thead>
                    <tr >
                        <th class="text-center">
                            Age
                        </th>
                        <th class="text-center">
                            Gender
                        </th>
                        <th class="text-center">
                            Interest
                        </th>
                        <th class="text-center">
                            Language
                        </th>
                        <th class="text-center">
                            Threshold
                        </th>
                        <th class="text-center">
                            Options
