How to fix "HttpMessageNotReadableException: Required request body is missing"? - json

Question

I'm integrating Angular with Spring boot for basic CRUD application with login module.
Login module is working fine, whereas, for creation method I get: "HttpMessageNotReadableException: Required request body is missing" for that particular method.
This is for a basic login and CRUD operation app with angular 7 and spring boot.
arrNewUser: any[] = [];
url = 'http://localhost:8080/api/user-management/add';
constructor(private http: HttpClient, private router: Router) { }
private options = { headers: new HttpHeaders().set('Content-Type', 'application/json') };
createUser(form: NgForm) {
this.arrNewUser = form.value;
console.log('array', this.arrNewUser);
console.log('value', form.value);
this.http.post(this.url, JSON.stringify(this.arrNewUser), this.options).subscribe((res: Response) => {
console.log('Response:--', res.status);
console.log(this.router.url);
});
}
#RestController
#RequestMapping(path="/api", method = {RequestMethod.GET, RequestMethod.POST})
#CrossOrigin(origins="http://localhost:4200")
public class ControllerClass {
#PostMapping(path="/user-management/add", produces = { MediaType.APPLICATION_JSON_UTF8_VALUE })
public Status addUsers(#RequestBody String data) {
.......
return status;
}
I'm able to get required output thru postman and thru localhost:4200 angular port, but not from localhost:8080 i.e., spring boot address.
