我在JSP初學者和我有以下的servlet:的doPost(GAE的servlet)不起作用
@SuppressWarnings("serial")
public class HelloAppIgorServlet extends HttpServlet {
public void doGet(HttpServletRequest req, HttpServletResponse resp) throws IOException, ServletException {
RequestDispatcher disp = req.getRequestDispatcher("/mainpage.jsp");
disp.forward(req, resp);
}
@Override
protected void doPost(HttpServletRequest req, HttpServletResponse resp) throws ServletException, IOException {
PrintWriter pw = resp.getWriter();
pw.print("Test");
pw.close();
}
}
和一個JSP文件調用mainpage.jsp:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
<p>Hello there!<p>
<form action="." method="post">
<input type="text" name="name1" />
<input type="submit" value="name2" />
</form>
</body>
</html>
的問題是doPost()方法不起作用。當我點擊按鈕時,它會將我重定向到index.html頁面。我確定這個問題不在servlet中,所以它在哪裏?
如果你在這裏輸入servlet的絕對URL,會發生什麼:'action =「。」'? –
它應該看起來像「action =」ProjectName/src/org/package/HelloAppIgorServlet.java「嗎? –
不,它應該是您在servlet的'web.xml'中定義的URL映射組件。 –
