@Controller
public class HelloWorldController {

        Book book = new Book();
        book.setId(123);
        book.setPrice(1);
        book.setPublished(new Date());
        book.setTitle("jcodjfop");
        Client client = ClientBuilder.newClient();
        client
                .target(REST_SERVICE_URL)
                .request()
                .post(Entity.entity(book, MediaType.APPLICATION_JSON));

这是调用的代码片段；

@Component
@Path("/book")
public class BookRest {
    @POST
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public Response saveBook(final Book book) {
        System.out.println(book);
        Book b=new Book();
        return Response.ok(b).build();
    }
}

这是resteasy服务；

Answer 1

当我把MediaType给我XML时服务端可以正常映射为Book对象，但是返回值只能是json或xml格式，无法映射为Book对象；

Client client = ClientBuilder.newClient();

        client

                .target(REST_SERVICE_URL)

                .request()

                .post(Entity.entity(book, MediaType.APPLICATION_XML)).readEntity(String.class);

Answer 2

当我把参数改为String类型时，接收到的参数为：

{"book":{"id":123,"title":"jcodjfop","price":1,"published":"2015-08-12T16:35:33.993+08:00"}}

不知道为什么为把book添加到json对象里，从而导致以上错误

@POST
    @Consumes(MediaType.APPLICATION_JSON)
    @Produces(MediaType.APPLICATION_JSON)
    public Response saveBook(String book) {
        System.out.println(book);
        Book b=new Book();
        return Response.ok(b).build();
    }
