I want to make POST request from Angular client. I have this Spring endpoint:

 @RestController()
public class HomeController 

 @PostMapping(value = "/payment/unique_transaction_id")
 public ResponseEntity<WpfResponse> handleWpfMessage(@PathVariable("unique_transaction_id") String unique_transaction_id,
 @RequestBody WpfPaymentsDTO transaction, HttpServletRequest request) throws Exception 

 /// .... 
 MessageProcessor messageProcessor = processors.getOrDefault(transaction.getTransaction_type(), defaultProcessor);
 return ResponseEntity.ok(messageProcessor.processMessage(merchant, contract, terminal.get(), transaction, request));
 

I use this typescript code:

save(main: MainForm, hash: string): void 
 const headers = new HttpHeaders();
 headers.append('Accept', 'application/json');
 headers.append('Content-Type', 'application/json');
 this.http.post('http://localhost:8080/some_package/payment/ckjzqtyxh5pnavbjecujhuvzaa5q8n74', JSON.stringify(main), headers ).subscribe();
 

But when I run the code I get:

HttpErrorResponse headers: HttpHeaders, status: 415, statusText: "Unsupported Media Type", url: "http://localhost:8080/some_package/payment/ckjzqtyxh5pnavbjecujhuvzaa5q8n74", ok: false, …error: nullheaders: HttpHeaders normalizedNames: Map(0), lazyUpdate: null, lazyInit: ƒlazyInit: ƒ ()lazyUpdate: nullnormalizedNames: Map(0) __proto__: Objectmessage: "Http failure response for http://localhost:8080/some_package/payment/ckjzqtyxh5pnavbjecujhuvzaa5q8n74: 415 Unsupported Media Type"name: "HttpErrorResponse"ok: falsestatus: 415statusText: "Unsupported Media Type"url: "http://localhost:8080/some_package/payment/ckjzqtyxh5pnavbjecujhuvzaa5q8n74"__proto__: HttpResponseBase

Do you know how I can solve this issue?

WpfPaymentsDTO:

public class WpfPaymentsDTO 

 private String transaction_id;

 private String transaction_type;

 private String currency;

 private Integer amount;
 .....

Give the content type in the PostMapping as so :

@PostMapping(path = "/payment/unique_transaction_id", consumes = "application/json", produces = "application/json")

Here "application/json" is just a sample. You can give the suitable type.

Check that you have Jackson added and configured in your Spring application. Refer to this question:
