有一个需要实现的 REST API 端点用于获取一些信息并将后端请求发送到另一台服务器，来自后端服务器的响应必须设置为最终响应。我的问题是如何在 javax.ws.rs.core.Response 中设置响应正文？
@Path("analytics")
@GET
@Produces("application/json")
public Response getDeviceStats(@QueryParam("deviceType") String deviceType,
@QueryParam("deviceIdentifier") String deviceIdentifier,
@QueryParam("username") String user, @QueryParam("from") long from,
@QueryParam("to") long to) {
// Trust own CA and all self-signed certs
SSLContext sslcontext = null;
try {
sslcontext = SSLContexts.custom()
.loadTrustMaterial(new File(getClientTrustStoretFilePath()), "password## Heading ##".toCharArray(),
new TrustSelfSignedStrategy())
.build();
} catch (NoSuchAlgorithmException e) {
log.error(e);
} catch (KeyManagementException e) {
log.error(e);
} catch (KeyStoreException e) {
log.error(e);
} catch (CertificateException e) {
log.error(e);
} catch (IOException e) {
log.error(e);
}
SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
sslcontext,
new String[] { "TLSv1" },
null,
SSLConnectionSocketFactory.getDefaultHostnameVerifier());
CloseableHttpClient httpclient = HttpClients.custom()
.setSSLSocketFactory(sslsf)
.build();
HttpResponse response = null;
try {
HttpGet httpget = new HttpGet(URL);
httpget.setHeader("Authorization", "Basic YWRtaW46YWRtaW4=");
httpget.addHeader("content-type", "application/json");
response = httpclient.execute(httpget);
String message = EntityUtils.toString(response.getEntity(), "UTF-8");
} catch (ClientProtocolException e) {
log.error(e);
} catch (IOException e) {
log.error(e);
}
}
Here messageis the one I need to set. But I tried several methods. Didn't work any of them.

One of the following solutions should do the trick:
以下解决方案之一应该可以解决问题：
return Response.ok(entity).build();
return Response.ok().entity(entity).build();
For more details, have a look at Responseand Response.ResponseBuilderclasses documentation.
有关更多详细信息，请查看Response和Response.ResponseBuilder类文档。
Tip: In the Response.ResponseBuilderAPI you might find some useful methods that allow you to add information related to cache, cookiesand headersto the HTTP response.
提示：在Response.ResponseBuilderAPI 中，您可能会找到一些有用的方法，这些方法允许您将与缓存、cookie和标头相关的信息添加到 HTTP 响应中。
