Question

我正在构建一个基于Angular / Spring MVC / Hibernate的Web应用程序。更具体地说，我正在尝试使用表单更新数据库条目，通过从客户端向服务器发送HTTP PUT请求，但我仍然收到415错误，即使我已为内容指定了正确的标头服务器的类型，即JSON。以下是我的代码。先感谢您。

前端http调用（来自dataService.ts）

const httpOptions = {
    headers: new HttpHeaders({ 'Content-Type': 'application/json'})
};

[...]

//Consulente - updateConsulente
updateConsulente(consulente: Consulente): Observable<Consulente> {
    return this.http.put(this.backendUrl + "/updateConsulente", consulente, httpOptions)
        .pipe(catchError(this.handleError));
}

支持映射（来自控制器java文件）

@PutMapping(value = "/updateConsulente", consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Consulente> updateConsulente(@RequestBody Consulente consulente) {
    consulenteService.aggiornaConsulente(consulente);
    Consulente c = consulenteService.findById(consulente.getIdConsulente());
    return new ResponseEntity<Consulente>(c, HttpStatus.OK);
}

我完全知道这个问题已经被问了很多，我读到这一切都试图解决这个问题，但到目前为止没有任何工作。

更新

在互联网上冲浪我明白问题可能是由于杰克逊依赖缺失错误，所以我也包括我目前的代表，如果有人可以指出一些缺失，我会非常感激。
