将输入设置为变量以传递到表中

Question

我有一个jsp文件，可以从用户那里获取员工ID输入。我希望将该输入发送到MySQL表中。我该怎么做？

<springForm:form method="POST" commandName="employee"
     <table>
      <tr>
          <td>Employee ID:</td>
          <td><springForm:input path="id" /></td>
          <td><springForm:errors path="id" cssClass="error" /></td>
      </tr>
      ....
      <%
       Connection con = null;
       try{
            Class.forName("com.mysql.jdbc.Driver").newInstance();
            con = DriverManager.getConnection("jdbc:mysql://localhost:3306/sakila","root","2scream4");
            PreparedStatement stat = con.prepareStatement("Insert into employee(id) VALUES(?)");
...

Answer 1

你做一个int id = request.getParameter("id");并将其传递给你准备好的陈述。

  PreparedStatement stat = con.prepareStatement("Insert into table_name VALUES(?)");
stat.setInt(1, id);
