SpringMVC HTTP Status 405 - Request method 'POST' not supported
提问by devdar
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.
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，它会将我带回我进行查询的页面，以便我可以更新记录。
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.
我单击更新将我带回控制器并使用相同的方法首先调用查询，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。似乎我无法将页面重新提交到相同的 url 映射。
Controller
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
}

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"`
检查 FireBug 我得到这个"NetworkError: 405 Method Not Allowed - http://localhost:8084/crimeTrack/getCitizen/citizen_registration.htm"应该是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.
getCitizen 是我第一次执行查询时进入的页面，它包含在 url 中。
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:
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

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
你可以调用上面提到的方法。使用 onclick 绑定提交按钮的功能
