Question

我是编程的初学者，我想要一些帮助。我想将数据从数据列表发送到我的其余服务器。所选项目和ID将发送到我在glassfish 5.191上运行的Restful服务器。我收到错误405方法不允许。我究竟做错了什么？我希望有一个人可以帮助我。我的前端是用Angular制造的。

我重新部署了服务器并检查了异常情况。

前端HTML文件：

<label for="codes">Choose a restaurant:</label>
    <form
      (ngSubmit)="onOrganize(f)"
      #f="ngForm">
      <input type="text"  list="codes"  [(ngModel)]=codeValue [ngModelOptions]="{standalone: true}" (change)="saveCode($event)">
      <datalist id="codes">
        <option *ngFor="let c of codeList" [value]="c.name" >{{c.name}}</option>
      </datalist>
    </form>

前端ts文件：

public codeValue: string;

  codeList = [
    { id: 1, name: 'Mcdonalds' },
    { id: 2, name: 'Kentucky Fried Chicken' },
    { id: 3, name: 'Burger King' },
    { id: 4, name: 'Domino`s pizza' },
    { id: 5, name: 'New York Pizza' }
  ];


  @ViewChild('f') form: NgForm;
  restaurant = {
    id: 0,
    name: ''
  };



  constructor(private http: HttpClient) {
  }

  ngOnInit() {
  }

  public saveCode(e): void {
    let name = e.target.value;
    let list = this.codeList.filter(x => x.name === name)[0];
    // console.log(list.id);
    // console.log(list.name)


    this.restaurant.id =  list.id;
    this.restaurant.name = list.name;


    this.http.post('http://localhost:8080/aquadine-jee/resources/restaurant', {
      id: this.restaurant.id,
      name: this.restaurant.name
    })

      .subscribe( // subscribe to observable http.post
        res => {
          console.log(res); // log results otherwise log error
        },
        err => {
          console.log('Error occured');
        }
      );

后端：

public class Restaurant {

    @Id

    private Integer id;

/
    private Integer restaurantId;
    private String naam;

//    @Column
//    @NotBlank
//    private String adres;

    public Restaurant(){

    }



    public Restaurant(Integer id, Integer restaurantId , String naam) {
        this.id = id;
        this.restaurantId = restaurantId;
        this.naam = naam;
    }

发布方法：

@POST
    @Path("restaurant")
    @Consumes("application/json")
    public Response save(Restaurant restaurant){
        repositoryService.save(restaurant);
        return Response
                .status(201)
                .build();
    }

@Stateless
@Path("restaurant")
public class RestaurantResource {

    @Inject
    private RepositoryService repositoryService;

    @GET
    @Path("restaurant")
    @Produces("application/json")
    public Response all(){
        List<Restaurant> all = repositoryService.getAllRestaurants();
        return Response
                .status(200)
                .header("Access-Control-Allow-Origin", "*")
                .entity(all)
                .build();
    }


    @GET
    @Produces("application/json")
    public List<Restaurant> getAllRestaurants(){
        return repositoryService.getAllRestaurants();

    }

    @POST
    @Path("restaurant")
    @Consumes("application/json")
    public Response save(Restaurant restaurant){
        repositoryService.save(restaurant);
        return Response
                .status(201)
                .build();
    }

    @PUT
    @Consumes("application/json")
    public void update(Restaurant restaurant) {
        repositoryService.update(restaurant);
    }

    @DELETE
    @Path("/{id}")
    @Consumes("application/json")
    public void delete(@PathParam("id") Integer id) {
        Restaurant restaurant = repositoryService.find(id);
        repositoryService.delete(restaurant);
    }


}

将数据发送到其余服务器时，POST http：// localhost：8080 405（不允许使用方法）
