I try to do POST request:
POST http://localhost:8080/api/add
Content-Type: application/json
{
"amount": "6",
"timestamp": "2021-01-31T14:35:01.00Z"
}
The response is:
HTTP/1.1 500
Content-Length: 0
Date: Sun, 31 Jan 2021 14:33:43 GMT
Connection: close
<Response body is empty>
Response code: 500; Time: 15ms; Content length: 0 bytes
there is my Controller:
@RestController
@RequestMapping(value = "/api")
public class StatsController {
private final StatisticService statisticsService;
@Autowired
public StatsController(StatisticService statisticsService) {
this.statisticsService = statisticsService;
}
@PostMapping(value = "/add")
public Transaction create(@RequestBody Transaction transaction) {
return statisticsService.createStats(transaction);
}
@GetMapping("/stats")
public Statistic getStats() {
return statisticsService.getStats();
}
}
But also I am receiving WARN message in Spring Boot:
2021-01-31 16:31:13.394 WARN 33984 --- [nio-8080-exec-1] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.http.converter.HttpMessageNotWritableException: No converter found for return value of type: class java.util.LinkedHashMap]
2021-01-31 16:33:43.651 WARN 33984 --- [nio-8080-exec-2] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.web.HttpMediaTypeNotSupportedException: Content type 'application/json;charset=UTF-8' not supported]
I tried different suggestions from similar problems:
consumes = MediaType.APPLICATION_JSON_VALUE
to RestController annotation.Nothing helped to me.
I have changed Spring Boot version from 2.4.2 to 2.4.0 and problem was fixed.
