How to fix "org.springframework.web.client.HttpClientErrorException: 405 Method Not Allowed" error

Did you get the error below when trying to post a form?

org.springframework.web.client.HttpClientErrorException: 405 Method Not Allowed
at org.springframework.web.client.DefaultResponseErrorHandler.handleError(DefaultResponseErrorHandler.java:91)
at org.springframework.web.client.RestTemplate.handleResponse(RestTemplate.java:614)
at org.springframework.web.client.RestTemplate.doExecute(RestTemplate.java:570)
at org.springframework.web.client.RestTemplate.execute(RestTemplate.java:530)
at org.springframework.web.client.RestTemplate.postForEntity(RestTemplate.java:357)
...

Here's how I fixed it:
open the controller class and go to the method that handles the request:


@RestController
@RequestMapping("/my-mapping")
public class MyController
@RequestMapping(value = "/commands/MyCommand", method = RequestMethod.PUT)
public void invoke(@RequestBody MyCommand command) {
...


change the method from RequestMethod.PUT (or whatever the value is) to RequestMethod.POST.

Restart the server and post the form again. That should fix the error
