@WebServlet(name = "SignUpServlet")
public class SignUpServlet extends HttpServlet {
protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
ApplicationContext ctx = new ClassPathXmlApplicationContext("lk/ruh/uniAssist/spring/SpringXMLConfig.xml");
SignUPService signUpservice = (SignUPService) ctx.getBean("signUpservice");
String username = request.getParameter("username");
String studentName = request.getParameter("studentName");
String regNo = request.getParameter("regNo");
String pwd = request.getParameter("pwd");
String department = request.getParameter("department");
String semester = request.getParameter("semester");
System.out.println(username);
System.out.println(studentName);
System.out.println(regNo);
System.out.println(pwd);
System.out.println(department);
System.out.println(semester);
RequestDispatcher requestDispatcher = request.getRequestDispatcher("signup.jsp");
requestDispatcher.include(request, response);
}
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
}
}
这是在dopost方法中的方式。当它是以上格式时没有任何反应。但是当我在doGet方法中声明RequestDispatcher方法时,它工作正常。这背后的原因是什么。

这是相关的jsp代码。

PS:在URL中使用signup.jsp时,它工作正常。但不适用于映射的URL / signUp。这是我试图解决的问题
答案 0 :(得分:0)
确保在form标签method = post和你的servlet类中重写方法doPost(HttpServletRequest req,HttpServletResponse resp)。
Bydefault表单标记方法是get,你的servlet类需要覆盖方法doGet(HttpServletRequest req,HttpServletResponse resp)。
如果你不匹配,你会得到R.E- HTTP方法这个URL不支持GET(即-HTTP状态405错误) P.S-完整文件。
