新建一個(gè)destination:
測試代碼:
try { Context ctx = new InitialContext(); ConnectivityConfiguration configuration = (ConnectivityConfiguration) ctx.lookup("java:comp/env/connectivityConfiguration"); DestinationConfiguration destConfiguration = configuration.getConfiguration(destinationName); if (destConfiguration == null) { response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR, String.format("Destination %s is not found. Hint:" + " Make sure to have the destination configured.", destinationName)); return; } // Get the destination URL String value = destConfiguration.getProperty("URL"); URL url = new URL(value + "xml?origins=Walldorf&destinations=Paris"); String proxyType = destConfiguration.getProperty("ProxyType"); Proxy proxy = getProxy(proxyType); urlConnection = (HttpURLConnection) url.openConnection(proxy); injectHeader(urlConnection, proxyType); // Copy content from the incoming response to the outgoing response InputStream instream = urlConnection.getInputStream(); OutputStream outstream = response.getOutputStream(); copyStream(instream, outstream); } catch (Exception e) { // Connectivity operation failed String errorMessage = "Connectivity operation failed with reason: " + e.getMessage() + ". See " + "logs for details. Hint: Make sure to have an HTTP proxy configured in your " + "local environment in case your environment uses " + "an HTTP proxy for the outbound Internet " + "communication."; LOGGER.error("Connectivity operation failed", e); response.sendError(HttpServletResponse.SC_INTERNAL_SERVER_ERROR, errorMessage); }
通過JNDI獲得destination配置的url:
