Question

我尝试了2天才找到关于这个问题的东西，但仍然没有得到它。我让我的Maven-Project在Wildfly上运行。

REST的代码：

@Override
    @GET
    @Path("{id}")
//  @Produces({ MediaType.APPLICATION_XML, MediaType.APPLICATION_JSON })
    public Customer getOverId(@PathParam("id") String id) {
        logger.info("put in " + this.getClass().getName() + " over id " + id);
//      if (id != null) {
//          Customer object = service.loadOneCustomer(new Integer(id));
//          logger.info("found in " + this.getClass().getName());
//          return Response.ok(object).build();
//      }
        Customer customer = service.loadOneCustomer(new Integer(id));
//      logger.info("nix found");
        if(customer == null) {
            throw new NotFoundException("No customer found with the matching ID: " + id);
        }
        logger.info("Customer found: " + customer.getCustomerNumber());
//      return Response.status(Status.BAD_REQUEST).build();
        return customer;
    }

客户实现：

public Response readCustomer(String id){
        log.info("Starting: Rest get a Customer with ID: " + id);
        log.info(this.URL);
        this.customerWebTarget = this.client.target(this.URL).path(id);
        Response response = this.customerWebTarget.request().buildGet().invoke();

//      TODO Customer cast application_xml auf Customer? Customer customer = response.readEntity(Customer.class);
        Customer customer = response.readEntity(Customer.class);

        log.info("Ending: Rest invoque a Customer with ID:" + customer.getCustomerNumber());
//      System.out.println("Ending: Rest get a Customer with ID: " + response.readEntity(String.class));

        return response;
    }

J-Unit测试：

@Test
    public void testGetCustomerById() throws Exception {

        Response response = this.customerRestClient.readCustomer("112");
        System.out.println("--->" + response.getStatus());
        Assert.assertTrue(response.getStatus() == 200);
    }

一切正常，直到我尝试从XML获取Java-Object（Customer customer = response.readEntity（Customer.class）;）

我错过了什么。我的意思是，我读取了xml-File并查看其中的每个数据...为什么我不能将它转换为Java-Object？

我总是得到这个错误：

Javax.ws.rs.ProcessingException: Unable to find a MEssageBody of content-type-application/xml and type class de.....model.Customer

Answer 1

没有看到Customer类，很难说，但很可能缺少部分或全部JAXB注释。特别是，您需要@XmlRootElement注释。

Answer 2

请您发布客户课程。它被正确注释了吗？还要重新添加@Produces。

RestEasy - 无法找到MessageBodyReader ... application / xml？
