SpringMVC HTTP 状态 405 - 不支持请求方法“POST”

Question

我有一个表单，我从该表单查询数据库并将结果发布到另一个页面。然后我从查询结果中选择一条记录，它会将我带回到我进行查询的页面，以便我可以更新记录。

我单击更新将我带回控制器并返回第一次调用查询的相同方法，但是请求的参数现在是“更新”，因此假设转到方法中的更新条件。好像我无法将页面重新提交到相同的 url 映射。

控制器

   @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

                }
    }

检查 FireBug 我得到了这个 "NetworkError: 405 Method Not Allowed - http://localhost:8084/crimeTrack/getCitizen/citizen_registration.htm" 这应该是 http://localhost:8084/crimeTrack/citizen_registration.htm"`

getCitizen 是我在第一次执行查询时进入的页面，它包含在 url 中。

我将 jsp 表单操作定义更改为 <form:form id="citizenRegistration" name ="citizenRegistration" method="POST" commandName="citizens" action="<%=request.getContextPath()%>/citizen_registration.htm"> 但是当我启动应用程序并向此页面发出请求时，我得到：

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();
}

你可以调用上面提到的方法。使用 onclick 绑定提交按钮的功能
