java - I want to use spring annotation @webservlet and call this servlet from a jsp page action form. But i got the error. Here it is: -

here servlet page here servlet , mapping pattern and

@webservlet("/logincontrol") public class sessioncontroller extends httpservlet { private static final long serialversionuid = 1l; public sessioncontroller() {     super(); } @requestmapping(value="/logincontrol") protected void doget(httpservletrequest request, httpservletresponse       response) throws servletexception, ioexception {   request.getsession().setattribute("name",request.getparameter("password"));     response.getwriter().println("hello world!"); } } 

and here jsp page , gave action url same given in @webservlet getting error. [org.springframework.web.servlet.pagenotfound] (default task-4) no mapping found http request uri [/myspring/logincontrol] in dispatcherservlet name 'mvcconfiguration'

<form name="loginform" action="logincontrol">          <table>             <tr>                 <td>user:</td>                 <td><input type='text' name='name'></td>             </tr>             <tr>                 <td>password:</td>                 <td><input type='password' name='password' /></td>             </tr>             <tr>                 <td colspan='2'><input name="submit" type="submit"                     value="submit" /></td>             </tr>         </table>     <%--          <input type="hidden" name="${_csrf.parametername}"             value="${_csrf.token}" /> --%>      </form> 

but remember dont want put entry in web.xml. in web.xml there 1 entry dispatcher servlet.

first of not use @requestmapping annotation on doget method. @requestmapping spring's controller method.

secondly have 2 servlet in application. 1 dispatcher servlet , login servlet. have tell request processed servlet.

currently spring's dispatcher servlet processing /logincontrol/* requests , there no controller method proper request mapping.

so have 2 option

1st instead of using @webservlet use @controller annotation on sessioncontroller class

@controller public class sessioncontroller { private static final long serialversionuid = 1l; public sessioncontroller() {     super(); } @requestmapping(value="/logincontrol") protected void doget(httpservletrequest request, httpservletresponse       response) throws servletexception, ioexception {   request.getsession().setattribute("name",request.getparameter("password"));     response.getwriter().println("hello world!"); }  } 

2nd use different mappings dispatcher servlet prevent processing /logincontrol/* requests.

example

<servlet>         <servlet-name>mvc-dispatcher</servlet-name>         <servlet-class>org.springframework.web.servlet.dispatcherservlet</servlet-class>         <load-on-startup>1</load-on-startup>     </servlet>  <servlet-mapping>     <servlet-name>mvc-dispatcher</servlet-name>     <url-pattern>/spring/*</url-pattern> </servlet-mapping> 

all request /spring/* processed springs dispatcher servlet.
