java - 如何将java对象从客户端传递到Web服务

Question

您好，我对 Web 服务还很陌生，我正在尝试将 java 对象传递到我创建的 Web 服务，其中它有一个采用 java 对象的 Web 方法。我在下面附上我的代码。

Web 服务类:

@WebService
public class WsTicketService {

    WsTicketStore ticketstore =  new WsTicketStore();

    @WebMethod
    public void createTicket(Ticket ticket) {
        System.out.println("Requested to store a new ticket");
        Ticket myTicket = ticketstore.storeNewTicket(ticket.getReporter(), ticket.getTopic(),ticket.getDescription(), ticket.getType(), ticket.getPriority());
        System.out.println("Ticket Stored");
    }
}

创建票证的客户端类我想将此票证发送到上述 Web 服务，但我在 service.createTicket(Ticket) 行上收到错误，表明该类型不适用于参数。

public class WsTicketManagementBackend implements TicketManagementBackend {
    HashMap<Integer, Ticket> localTicketStore = new HashMap<>();
    AtomicInteger nextId;


    WsTicketServiceService client;
    WsTicketService service;

    public WsTicketManagementBackend() {
        nextId = new AtomicInteger(1);

        this.client = new WsTicketServiceService();
        service = client.getWsTicketServicePort();
    }

    @Override
    public void triggerShutdown() {

    }

    @Override
    public Ticket createNewTicket(String reporter, String topic, String description, Type type, Priority priority) {
        Ticket ticket = new Ticket(nextId.getAndIncrement(), reporter, topic, description, type, priority);
        localTicketStore.put(ticket.getId(), ticket);
        service.createTicket(ticket);
        return (Ticket) ticket.clone();
    }

该接口(interface)由wsimport工具生成:

public interface WsTicketService {


    /**
     * 
     * @param arg0
     */
    @WebMethod
    @RequestWrapper(localName = "createTicket", targetNamespace = "http://implementation.remote.ws.backend.rz.uniba.de/", className = "de.uniba.rz.backend.ws.remote.implementation.CreateTicket")
    @ResponseWrapper(localName = "createTicketResponse", targetNamespace = "http://implementation.remote.ws.backend.rz.uniba.de/", className = "de.uniba.rz.backend.ws.remote.implementation.CreateTicketResponse")
    @Action(input = "http://implementation.remote.ws.backend.rz.uniba.de/WsTicketService/createTicketRequest", output = "http://implementation.remote.ws.backend.rz.uniba.de/WsTicketService/createTicketResponse")
    public void createTicket(
        @WebParam(name = "arg0", targetNamespace = "")
        Ticket arg0);

}

您可以尝试发送包含 Ticket 对象属性的 json 字符串，然后创建它，如下所示:

createTicket(String jsonTicket){
// Instantiate a jsonObject (you can use any json library you want, I recommend PrimeFaces JSONObject)
JSONObject json = new JSONObject(jsonTicket);
// So here you make a new ticket
Ticket ticket = new Ticket();
// Set the properties of the ticket to each attribute of your json
ticket.setName(json.getString("name"));
// and so on
}
