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个服务器,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中设置响应主体?
@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);
}
}
此处消息是我需要设置的消息。但我尝试了几种方法。没有工作任何一个。

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();
有关详细信息,请查看Response
和Response.ResponseBuilder
类文档。
提示:在Response.ResponseBuilder
API中,您可能会找到一些有用的方法,可让您添加与cache,cookies和{{3}相关的信息到HTTP响应。
