javaweb form表单的提交问题

Question

<form action="/AddDataServlet" id="addDataForm" method="post">

<servlet> <description></description> <display-name>AddDataServlet</display-name> <servlet-name>AddDataServlet</servlet-name> <servlet-class>servlet.AddDataServlet</servlet-class> </servlet> <servlet-mapping> <servlet-name>AddDataServlet</servlet-name> <url-pattern>/AddDataServlet</url-pattern> </servlet-mapping>
为什么点提交，数据传不到servlet里面呢？

Answer 1

action="/AddDataServlet" id="addDataForm" method="post"这句话改成
action=“AddDataServlet" id="addDataForm" method="post"试试

Answer 2

request.getParameter(yourParameterName);
