Getting “405 - Request method 'GET' not supported when calling” method=DELETE

Question

I have a Spring MVC web app. In it a form with a button that's supposed to delete a resource from another resource:

<td>
    <form action="/product-bases/${productBase.id}/positions/${position.id}" method="DELETE">
        <input type="submit" value="delete" />
    </form>
</td>

My controller:

@Controller
@RequestMapping(value = "/product-bases/{id}/positions")
public class ProductBasePositionController {

    @RequestMapping(value = "/{positionId}", method = RequestMethod.DELETE)
    public ModelAndView delete(@PathVariable Integer productBaseId, @PathVariable Integer positionId) {

So in theory the server should route to the controller. But alas it does not, hence the post ;)

I'm getting

HTTP Status 405 - Request method 'GET' not supported

type Status report

message Request method 'GET' not supported

description The specified HTTP method is not allowed for the requested resource (Request method 'GET' not supported).
Apache Tomcat/7.0.19

Obviously I don't have a get for /positions/id defined yet, but why should I, I want to do a delete for now..

(I'm also trying to run this from my spring-test-mvc framework on a mock servlet without any tomcat implementation in between and it gives me a 400 - bad request.. )

So what am I missing here?

Oh, just to cut some corners: post and get will work for other resources, so the rest of my setup is fine.

The booting server even tells me:

RequestMappingHandlerMapping [INFO] Mapped "{[/product-bases/{id}/positions/{positionId}],methods=[DELETE],params=[],headers=[],consumes=[],produces=[],custom=[]}" onto public org.springframework.web.servlet.ModelAndView our.view.controller.ProductBasePositionController.delete(java.lang.Integer,java.lang.Integer)

Anyone as confused as I am? If less so, please enlighten me!

Answer 1

Forms can be submitted via GET or POST only (maybe also PUT , but I doubt that is widely implemented), as form submission requires a method where data is transmitted to the server.

The DELETE method does not have a request body, so specifying it in a form action is unsupported.

Do you have the HiddenHttpMethodFilter filter in your web.xml?

<filter>
    <filter-name>hiddenHttpMethodFilter</filter-name>
    <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class>
</filter>
<filter-mapping>
    <filter-name>hiddenHttpMethodFilter</filter-name>
    <url-pattern>/*</url-pattern>
</filter-mapping>

The error messages indicate that the browser is actually sending a GET request rather than a DELETE request.

What you need to do is:

• examine the source of the web page that the browser is on at the time, and

• using the browser's web debugger, see what the request URL and method actually are.

In Microsoft Azure portal i got this error for a Java App when i turned on Authentication/Authorization. If it's the same problem in your case, revert your action.
