GetMapping and PostMapping-CodePudding

@RestController public class HelloWorldController {

@GetMapping(path="/helloWorld")
public String helloWorld() {
    return "Hello-World";
}

}

I am new to RestFul WebServices. I tried to annotate the helloWorld() with PostMapping but it failed. Using GetMapping, it successfully gets executed.

Can somebody tell me why PostMapping was not allowed?

CodePudding user response：

PostMapping for POST request.

GetMapping for GET request.

If you want call PostMapping success, you can use Postman or SoapUI, curl for testing HTTP POST request.

In addition to @Do Nhu Vys answer. You will often encounter problems with CORS and CRFS while performing Post Requests.
