從Resteasy 2.4升級到3.0.5後，我的客戶端調用再也無法工作。我期待的實體（就像String一樣簡單）始終爲空。在調試模式下，我可以看到它在服務器端的Response對象中設置，但在客戶端，Response中的實體爲空。下面是一個例子電話：用RestEasyWebTarget替換ProxyFactory不起作用
接口：
/**
* @return all expired licenses
*/
@GET
@ClientResponseType(entityType = LicenseList.class)
@Path("/expired")
@Produces(MediaType.APPLICATION_XML)
public Response getExpiredLicenses();
實施：
/**
* @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();
}
的測試呼叫：
@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" })));
}
}

的LicenseList類：
@XmlRootElement(name = "LicenseList")
@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "licenseList", propOrder = {
"licenses"
})
public class LicenseList {
@XmlElement(name = "Licenses", required = true)
protected List<License> licenses;
/**
* Gets the value of the licenses property.
*
* <p>
* This accessor method returns a reference to the live list,
* not a snapshot. Therefore any modification you make to the
* returned list will be present inside the JAXB object.
* This is why there is not a <CODE>set</CODE> method for the licenses property.
*
* <p>
* For example, to add a new item, do as follows:
* <pre>
* getLicenses().add(newItem);
* </pre>
*
*
* <p>
* Objects of the following type(s) are allowed in the list
* {@link License }
*
*
*/
public List<License> getLicenses() {
if (licenses == null) {
licenses = new ArrayList<License>();
}
return this.licenses;
}
}
我使用JDK 1.7，Tomcat的7.0.47
