Ошибка Spring Boot Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported

в общем я пытаюсь получить данные с textaria в формате json отправить их в бд

@RestController
public class RESTCustCtrl {
@Autowired
private CustomerRepo customerRepo;
@RequestMapping(value = "sendStmt", method = RequestMethod.POST)
public CustomerStatement custStmt(@RequestBody CustomerStatement customerStatement){
    customerRepo.save(customerStatement);
    return customerStatement;
}
}

получаю ошибку Content type 'application/x-www-form-urlencoded;charset=UTF-8' not supported

если убираю аннотацию @RequestBody, а пишу

public @ResponceBody CustomerStatement custStmt(CustomerStatement customerStatement)

то получаю json со значениями полей 0 или non

@Entity
public class CustomerStatement {
@Id
@GeneratedValue(strategy= GenerationType.AUTO)
private  long id;
private  String request;
private  float bid;
private Date due_date;
private  Boolean status = false;
public CustomerStatement(String request, float bid, Date due_date) {
    this.id = id;
    this.request = request;
    this.bid = bid;
    this.due_date = due_date;
    this.status = status;
}
public CustomerStatement(){}
public long getId() {
    return id;
}
public void setId(long id) {
    this.id = id;
}
public String getRequest() {
    return request;
}
public void setRequest(String request) {
    this.request = request;
}
public float getBid() {
    return bid;
}
public void setBid(float bid) {
    this.bid = bid;
}
public Date getDue_date() {
    return due_date;
}
public void setDue_date(Date due_date) {
    this.due_date = due_date;
}
public Boolean getStatus() {
    return status;
}
public void setStatus(Boolean status) {
    this.status = status;
}

}
