[PHP知识库]Servlet处理多表单问题

其实解决办法很简单，即在表单内设置一个唯一且隐藏的标签，用于存放标志该表单的值，servlet通过name获取标签的值,即可判断该表单是哪个表单。核心代码如下：
servlet:

public class UserServlet extends HttpServlet {
    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
    // 获取name为type的标签的值
        String type = req.getParameter("type");
        if("updateUserInfo".equals(type)){
            this.updateUserInfo(req,resp);
        }
        if ("updatePassword".equals(type)){
            this.updatePassword(req,resp);
        }
    }

    @Override
    protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
        doGet(req, resp);
    }

    public void updateUserInfo(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException{}

    public void updatePassword(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException{}
}

jsp1(表单1):

<form action="#" name="userInfo" class="userInfo" id="userInfoForm" method="post">
<!--    用于在servlet中辨别是哪个请求-->
    <input type="hidden" name="type" value="updateUserInfo">
 
    </div>

jsp2(表单2):

<form action="#" name="userpassword" class="updatePassword" id="updatePassword" method="post">
<!--    用于在servlet中辨别是哪个请求-->
    <input type="hidden" name="type" value="updatePassword">
 
    </div>
