Im getting this error: HTTP Status 405 - Request method 'POST' not supported
What I am trying to do is make a form with a drop down box that get populated based on the other value selected in another drop down box. For example when I select a name in the customerName box the onChange function in the .jsp page should be run and the page submitted then loaded again with the corresponding values in the customerCountry box.
however I'm getting this HTTP Status 405 error. I have searched the internet for a solution but haven't been able to find anything that helped. Here is the relevant parts of my code:
part of jsp page
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>Insert title here</title>
<style>
.error { color: red; }
</style>
<script>
function repopulate(){
document.deliveryForm.submit();
}
function setFalse(){
document.getElementById("hasId").value ="false";
document.deliveryForm.submit();
// document.submitForm.submit(); (This was causing the error)
}
</script>
</head>
<body>
<h1>Create New Delivery</h1>
<c:url var="saveUrl" value="/test/delivery/add" />
<form:form modelAttribute="deliveryDtoAttribute" method="POST" action="${saveUrl}" name="deliveryForm">
<table>
<tr>
<td><form:hidden id="hasId" path="hasCustomerName" value="true"/></td>
</tr>
<tr>
<td>Customer Name</td>
<td><form:select path="customerName" onChange="repopulate()">
<form:option value="" label="--- Select ---" />
<form:options items="${customerNameList}" />
</form:select>
</td>
<td><form:errors path="customerName" cssClass="error" /></td>
</tr>
<tr>
<td>Customer Country</td>
<td><form:select path="customerCountry">
<form:option value="" label="--- Select ---" />
<form:options items="${customerCountryList}" />
</form:select>
</td>
<td><form:errors path="customerCountry" cssClass="error" /></td>
</tr>
</form:form>
<form:form name="submitForm">
<input type="button" value="Save" onClick="setFalse()"/>
</form:form>
</body>
</html>
part of controller:
@RequestMapping(value = "/add", method = RequestMethod.GET)
public String getDelivery(ModelMap model) {
DeliveryDto deliveryDto = new DeliveryDto();
model.addAttribute("deliveryDtoAttribute", deliveryDto);
model.addAttribute("customerNameList",
customerService.listAllCustomerNames());
model.addAttribute("customerCountryList", customerService
.listAllCustomerCountries(deliveryDto.getCustomerName()));
return "new-delivery";
}
// I want to enter this method if hasId=true which means that a value in the CustomerName
// drop down list was selected. This should set the CountryList to the corresponding values
// from the database. I want this post method to be triggered by the onChange in the jsp page
@RequestMapping(value = "/add", method = RequestMethod.POST, params="hasCustomerName=true")
public String postDelivery(
@ModelAttribute("deliveryDtoAttribute") DeliveryDto deliveryDto,
BindingResult result, ModelMap model) {
model.addAttribute("deliveryDtoAttribute", deliveryDto);
model.addAttribute("customerNameList",
customerService.listAllCustomerNames());
model.addAttribute("customerCountryList", customerService
.listAllCustomerCountries(deliveryDto.getCustomerName()));
return "new-delivery";
}
// This next post method should only be entered if the save button is hit in the jsp page
@RequestMapping(value = "/add", method = RequestMethod.POST, params="hasCustomerName=false")
public String postDelivery2(
@ModelAttribute("deliveryDtoAttribute") @Valid DeliveryDto deliveryDto,
BindingResult result, ModelMap model) {
if (result.hasErrors()) {
model.addAttribute("deliveryDtoAttribute", deliveryDto);
model.addAttribute("customerNameList",
customerService.listAllCustomerNames());
model.addAttribute("customerCountryList", customerService
.listAllCustomerCountries(deliveryDto.getCustomerName()));
return "new-delivery";
} else {
Delivery delivery = new Delivery();
//Setters to set delivery values
return "redirect:/mis/home";
}
}
How come I get this error? Any help would be much appreciated! Thanks
EDIT: Changed hasId to hasCustomerName. I still get the HTTP Status 405 - Request method 'POST' not supported error though.
EDIT2: Commented out the line in the setFalse function that was causing the error

I am not sure if this helps but I had the same problem.
You are using springSecurityFilterChain with CSRF protection. That means you have to send a token when you send a form via POST request. Try to add the next input to your form:
<input type="hidden" name="${_csrf.parameterName}" value="${_csrf.token}"/>

Check if you are returning a @ResponseBody or a @ResponseStatus
I had a similar problem. My Controller looked like that:
@RequestMapping(value="/user", method = RequestMethod.POST)
public String updateUser(@RequestBody User user){
return userService.updateUser(user).getId();
}
When calling with a POST request I always got the following error:
HTTP Status 405 - Request method 'POST' not supported
After a while I figured out that the method was actually called, but because there is no @ResponseBody and no @ResponseStatus Spring MVC raises the error.
To fix this simply add a @ResponseBody
@RequestMapping(value="/user", method = RequestMethod.POST)
public @ResponseBody String updateUser(@RequestBody User user){
return userService.updateUser(user).getId();
}
or a @ResponseStatus to your method.
@RequestMapping(value="/user", method = RequestMethod.POST)
@ResponseStatus(value=HttpStatus.OK)
public String updateUser(@RequestBody User user){
return userService.updateUser(user).getId();
}

You might need to change the line
@RequestMapping(value = "/add", method = RequestMethod.GET)
to
@RequestMapping(value = "/add", method = {RequestMethod.GET,RequestMethod.POST})
回答4:
The problem is that your controller expect a parameter hasId=false or hasId=true, but you are not passing that. Your hidden field has the id hasId but is passed as hasCustomerName, so no mapping matches.
Either change the path of the hidden field to hasId or the mapping parameter to expect hasCustomerName=true or hasCustomerName=false.

I found the problem that was causing the HTTP error.
In the setFalse() function that is triggered by the Save button my code was trying to submit the form that contained the button.
function setFalse(){
document.getElementById("hasId").value ="false";
document.deliveryForm.submit();
document.submitForm.submit();
when I remove the document.submitForm.submit(); it works:
function setFalse(){
document.getElementById("hasId").value ="false";
document.deliveryForm.submit()
@Roger Lindsjö Thank you for spotting my error where I wasn't passing on the right parameter!
