Java 用RestEasyWebTarget替换ProxyFactory无效

从Resteasy 2.4升级到3.0.5后，我的客户机再也不能工作了。我期望的实体（像字符串一样简单）总是空的。在调试模式下，我可以看到它被设置在服务器端的响应对象中，但在客户端，响应中的实体为null。下面是一个示例调用：

界面：

  /**
   * @return all expired licenses
   */
  @GET
  @ClientResponseType(entityType = LicenseList.class)
  @Path("/expired")
  @Produces(MediaType.APPLICATION_XML)
  public Response getExpiredLicenses();

实施：

  /**
   * @return all expired licenses
   */
  @Override
  public Response getExpiredLicenses() {
    try {
      LicenseList list = LicensesDBUtil.getExpiredLicenses();
      Response resp = Response.ok().entity(list).build();
      return resp;
    } catch (SQLException e) {
      LOG.error("Error getting expired licenses : " + e.getMessage());
      return   Response.status(Status.INTERNAL_SERVER_ERROR).entity(e.getMessage()).type(MediaType.TEXT_PLAIN).build();
    }

测试调用：

  @Test
  public void testGetExpiredLicenses() throws Exception {
        ResteasyClientBuilder rsb = new ResteasyClientBuilder();
    ResteasyClient rsc = rsb.build();
    ResteasyWebTarget target = rsc.target(BASEURL);
    return target.proxy(RiskScapeLicenseService.class);
    Response response = client.getExpiredLicenses();
    assertTrue(HttpResponseCodes.SC_OK == response.getStatus());
    @SuppressWarnings("unchecked")
    JAXBElement<LicenseList> element = (JAXBElement<LicenseList>) response.getEntity();
    LicenseList list = element.getValue();
    assertEquals(4, list.getLicenses().size());
    for (License lic : list.getLicenses()) {
      assertTrue((new Date()).after(DateUtils.parseDate(lic.getValidTo(), new String[] { "yyyy-MM-dd" })));
    }
  }

* * * *列表中允许以下类型的对象 *{@link License} * * */ 公共列表getLicenses（）{ 如果（许可证==null）{ 许可证=新的ArrayList（）； } 退还此许可证； } }

我使用的是JDK1.7、Tomcat7.0.47，因此，我通过使用jaxb:version=“2.0”更新模式解决了我的问题 以及重新生成jaxb类。消息是有人提到有一个 Resteasy客户端->JAX-RS 2.0不匹配迁移问题。 还要注意的是，在这个jaxb版本中，Generator仍然省略了XMLRootElement，因此需要将它添加到所有用作POST请求输入的类中
