I have made a hello world rest service using spring boot. I am able to call the service via standalone java program. I am also able to call it via Advanced Rest Client add-on for Chrome.
But when I try to hit it via a standalone HTML page using jQuery AJAX I am getting error
WARN 3748 --- [nio-9000-exec-2] o.s.web.servlet.PageNotFound : Request method 'GET' not supported
Any Help is appreciated.
PS: I am assuming that as I am able to call the WebService using other modes so the controller is fine. But something is wrong the way I am calling it from the HTML.
HTML Page Below:

The Request Method' POST' Not Supported error is caused by a mismatch of the web browser configuration and the browser's URL format. In this case, the browser sends a URL request, the web server receives and recognizes the URL but cannot execute commands or grant access to the requested page.
405 Not Support – Reason, Solution As we can expect, we can solve this by defining an explicit mapping for PUT in the existing method mapping: @RequestMapping( value = "/employees", produces = "application/json", method = {RequestMethod. GET, RequestMethod.
Return 405 (Method Not Allowed), unless you want to replace every resource in the entire collection of resource - use with caution. 404 (Not Found) - if id not found or invalid and creating new resource is not allowed. Return 405 (Method Not Allowed), unless you want to modify the collection itself..
In this article, we will discuss how to get the body of the incoming request in the spring boot. @RequestBody: Annotation is used to get request body in the incoming request. Note: First we need to establish the spring application in our project. Step 2: Click on Generate which will download the starter project.
I guess the solution is described here: Why SpringMVC Request method 'GET' not supported?
Both values in the RequestMapping has to be the same. So for each value you have to define one for GET and one for POST.
@RequestMapping(value="/rest/greetMe", method= RequestMethod.GET)
public @ResponseBody Greeting sayHello(
@RequestParam(value = "name", required = false, defaultValue = "Stranger") String name,
@RequestParam(value = "language", required = false, defaultValue = "en") String language) {
return new Greeting(counter.incrementAndGet(), String.format(getTemplate(language), name));
}
@RequestMapping(value="/rest/greetMe", method= RequestMethod.POST)
public @ResponseBody Greeting sayHello(
@RequestBody(required = true) Input input) {
return new Greeting(counter.incrementAndGet(),
String.format(getTemplate(input.getLanguage()), input.getName()));
}
Check your controller, if you have mapped any of these calls to default mapping:
@DeleteMapping()
@PostMapping()
@GetMapping()
It is mapped to path="/". Please change it to
@DeleteMapping(path="/something")
@PostMapping(path="/something")
@GetMapping(path="/something")
