Question

我正在maven项目中编写一个休息客户端

public class MyRestClient {

    public static void main(String[] args)

    {
        Client client= ClientBuilder.newClient();
        //Response response=     client.target("http://localhost/advanced-jaxrs-01/webapi/messages/1").request().get();
        Response response=  client.target("http://localhost:80/advanced-jaxrs-01/webapi/messages/1").request().get();
        Message mess=response.readEntity(Message.class);
        System.out.println(mess.getMessage());
        System.out.println(response);
    }
}

我的资源在下面并消耗JSON

@Path("/messages")
@Consumes(MediaType.APPLICATION_JSON)
@Produces(MediaType.APPLICATION_JSON)
public class MessageResource {

    MessageService messageService = new MessageService();

    @GET
    public List<Message> getMessages(@BeanParam MessageFilterBean filterBean) {

        if (filterBean.getYear() > 0) {
            return messageService.getAllMessagesForYear(filterBean.getYear());
        }
        if (filterBean.getStart() >= 0 && filterBean.getSize() > 0) {
            return messageService.getAllMessagesPaginated(filterBean.getStart(), filterBean.getSize());
        }
        return messageService.getAllMessages();
    }

    @POST
    public Response addMessage(Message message, @Context UriInfo uriInfo) {

        Message newMessage = messageService.addMessage(message);
        String newId = String.valueOf(newMessage.getId());
        URI uri = uriInfo.getAbsolutePathBuilder().path(newId).build();
        return Response.created(uri)
                .entity(newMessage)
                .build();
    }

    @PUT
    @Path("/{messageId}")
    public Message updateMessage(@PathParam("messageId") long id, Message message) {
        message.setId(id);
        return messageService.updateMessage(message);
    }

    @DELETE
    @Path("/{messageId}")
    public void deleteMessage(@PathParam("messageId") long id) {
        messageService.removeMessage(id);
    }


    @GET
    @Path("/{messageId}")
    public Message getMessage(@PathParam("messageId") long id, @Context UriInfo uriInfo) {
        Message message = messageService.getMessage(id);
        message.addLink(getUriForSelf(uriInfo, message), "self");
        message.addLink(getUriForProfile(uriInfo, message), "profile");
        message.addLink(getUriForComments(uriInfo, message), "comments");

        return message;

    }

    private String getUriForComments(UriInfo uriInfo, Message message) {
        URI uri = uriInfo.getBaseUriBuilder()
                .path(MessageResource.class)
                .path(MessageResource.class, "getCommentResource")
                .path(CommentResource.class)
                .resolveTemplate("messageId", message.getId())
                .build();
        return uri.toString();
    }

    private String getUriForProfile(UriInfo uriInfo, Message message) {
        URI uri = uriInfo.getBaseUriBuilder()
             .path(ProfileResource.class)
             .path(message.getAuthor())
             .build();
        return uri.toString();
    }

    private String getUriForSelf(UriInfo uriInfo, Message message) {
        String uri = uriInfo.getBaseUriBuilder()
         .path(MessageResource.class)
         .path(Long.toString(message.getId()))
         .build()
         .toString();
        return uri;
    }




    @Path("/{messageId}/comments")
    public CommentResource getCommentResource() {
        return new CommentResource();
    }

}

但是当我正在运行我的休息客户端时，我遇到了错误。我试图调试并提供其他依赖项，但我仍然无法运行此错误。我想我仍然在休息客户端使用方法.request（）。get（）的正确球衣版本。你能帮我解决这个问题吗？

大多数情况下，你有jar版本和包问题。检查this SO question。此外，反编译这些jar的不同版本，并查看哪些类和方法存在，哪些不存在，然后使用相关的类。你可以在网上找到好的java反编译器。
