Answer 1

From the code, it seems you are trying to retrieve an account based on the customer id. In that case, it will be @GetMapping and not @PostMapping ( at line 12). Also, in case of get, we pass the variables in the url and not in the request body. As a coding practice, the className should start with a capital letter ( the return type of your method should be Account and not accounts )

@GetMapping("/myAccount/{id}


public Account AccountsGetAccountDetails(@PathVariable String id ) {}
