SpringMVC HTTP状态405-请求方法'POST'不支持

Question

I have a form i query the database from that form and is posted to another page with the results. I then select one record from the query results and it takes me back to the page i made the query from so i can update the record.

I click update which takes me back to the controller and to tahe same method first called to query, however the requested parameter is now 'update' so it is suppose to go to the update condition in the method. It seems as though i cannot re-submitt the page to the same url mapping.

Controller

   @RequestMapping(value="citizen_registration.htm", method = RequestMethod.POST)
    public ModelAndView handleRequest(@Valid @ModelAttribute Citizens citizen, 
            BindingResult result,  ModelMap m, Model model,
            @RequestParam(value="user_request") String user_request) throws Exception {


        try{
             logger.debug("In Http method for CitizenRegistrationController - Punishment Registration");
             logger.debug("User Request Is " + user_request);


                 if(result.hasErrors()){

                //handle errors

                    // return new ModelAndView("citizen_registration");
                 }else{

                     //check if its a save or an update

                     if(user_request.equals("Save"))
                        //do save

                        else if (user_request.equals("Query"))

                        //do query

                        else if (user_request.equals("Update"))
                        //do update

                }
    }

FireBug

Inspecting FireBug I got this "NetworkError: 405 Method Not Allowed - http://localhost:8084/crimeTrack/getCitizen/citizen_registration.htm" this should be http://localhost:8084/crimeTrack /citizen_registration.htm"`

The getCitizen is the page i was taken to when the query was first executed it got included in the url.

I changed the jsp form action definition to <form:form id="citizenRegistration" name ="citizenRegistration" method="POST" commandName="citizens" action="<%=request.getContextPath()%>/citizen_registration.htm"> however when i start the application and make a request to this page i get:

HTTP Status 500 - /WEB-INF/jsp/citizen_registration.jsp (line: 31, column: 116) attribute for %>" is not properly terminated 

Answer 1

function submitPage(){
     document.getElementById("citizenRegistration").action="getCitizen/citizen_registration.htm";
     document.getElementById("citizenRegistration").target="_self";    
     document.getElementById("citizenRegistration").method = "POST";
     document.getElementById("citizenRegistration").submit();
}

you can call the method as mentioning the above. bind the function for your submit button using onclick
