将HTML表单数据数组发送到JSP/Servlet

<form action="MyServlet" method="post">
   <input type="text" name="data[0].name" value="John" />
   <input type="text" name="data[0].age" value="30" />
   <input type="text" name="data[1].name" value="Jane" />
   <input type="text" name="data[1].age" value="25" />
   <input type="submit" value="Submit" />
</form>

protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
    String[] names = request.getParameterValues("data[].name");
    String[] ages = request.getParameterValues("data[].age");

    for (int i = 0; i< names.length; i++) {
        String name = names[i];
        int age = Integer.parseInt(ages[i]);
        // 处理数据，如将其保存到数据库中
    }
}

    <tr>
        <th>Name</th>
        <th>Age</th>
    </tr>
    <c:forEach var="item" items="${data}">
        <tr>
            <td>${item.name}</td>
            <td>${item.age}</td>
        </tr>
    </c:forEach>
