enter image description here公共类GemfireTest扩展了SecurityManager {

public static void main(String[] args) throws NameResolutionException, TypeMismatchException, QueryInvocationTargetException, FunctionDomainException, IOException {

                System.setProperty("gemfire.locators", "localhost[8091]");
                Properties properties = new Properties();

             ServerLauncher serverLauncher = new ServerLauncher.Builder()

                        .setMemberName("server1")
                        .setServerPort(40404)
                        .set("start-locator", "localhost[8091]")
            .build();
                serverLauncher.start();
                System.out.println(serverLauncher.status());
String restapi ="http://localhost:8091/gemfire-api/v1/";
             //   URLConnection urlConnection = new URL(restapi).openConnection();
                try {
                    URL obj = new URL(restapi);
                    HttpURLConnection con = (HttpURLConnection) obj.openConnection();
                    con.setRequestMethod("GET");
                    con.setRequestProperty("accept","application/json");
                    int responseCode = con.getResponseCode();
                    System.out.println(responseCode);
                   // if (responseCode == HttpURLConnection.HTTP_OK) { // success
                        BufferedReader in = new BufferedReader(new InputStreamReader(
                                con.getInputStream()));
                        String inputLine;
                        StringBuffer response = new StringBuffer();

                        while ((inputLine = in.readLine()) != null) {
                            response.append(inputLine);
                        }
                        in.close();

                        // print result
                        System.out.println("reason"+response.toString());

服务器在C：\ Users \ xxx \ IdeaProjects \ Gemfire上DESKTOP-MRCV2EH [40404]，因为server1当前在线 . 进程ID：2640正常运行时间：7秒Geode版本：9.5.1 Java版本：1 . 0 . 0 - 171日志文件：C：\ Users \ xxx \ IdeaProjects \ Gemfire \ server1.log JVM参数：-Dgemfire.enable-cluster-configuration = true -Dgemfire.load-cluster-configuration-from-dir = false -Dgemfire.jmx-manager-bind-address = localhost -Djava.rmi.server.hostname = localhost -Dgemfire.launcher.registerSignalHandlers = true -Djava.awt.headless = true -javaagent：C：\ Program Files \ JetBrains \ IntelliJ IDEA Community Edition 2017.3.2 \ lib \ idea_rt.jar = 54053：C：\ Program Files \ JetBrains \ IntelliJ IDEA Community Edition 2017.3.2 \ bin -Dfile.encoding = UTF-8

获取响应代码：-1，无效的Http响应 .

我该如何解决这个问题？

    我已在本地测试了您的源代码（加上一两个小修改），一切似乎都运行得很好：

    public static void main(String[] args) throws IOException {
    Integer httpServicePort = 8080;
    ServerLauncher serverLauncher = 
        new ServerLauncher.Builder()
        .set("log-file", "")
        .set("http-service-port", httpServicePort.toString())   
        .set("start-dev-rest-api", "true")
        .set("http-service-bind-address", "localhost")
        .setPdxReadSerialized(true)
        .build();

    serverLauncher.start();
    System.out.println("REST server successfully started, press any key to stop it...");
    String restapi ="http://localhost:" + httpServicePort + "/gemfire-api/v1/";

    try {
        URL obj = new URL(restapi);
        HttpURLConnection con = (HttpURLConnection) obj.openConnection();
        con.setRequestMethod("GET");
        con.setRequestProperty("accept","application/json");
        int responseCode = con.getResponseCode();
        System.out.println("Response Code: " + responseCode);

         if (responseCode == HttpURLConnection.HTTP_OK) { // success
               BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));
               String inputLine;
               StringBuffer response = new StringBuffer();
               while ((inputLine = in.readLine()) != null) {
                   response.append(inputLine);
               }

               in.close();
               System.out.println("Response: " + response.toString());
         }
    } catch (Exception exception) {
        exception.printStackTrace();
    }

    System.in.read();
    serverLauncher.stop();
    System.exit(0);
}

    运行上述程序将打印以下内容：

    REST server successfully started, press any key to stop it...
Response Code: 200
Response: {  "regions" : [ ]}

    您是否正确设置了 GEODE_HOME 环境变量？，执行 curl 命令时使用的 port 与您通过 http-service-port 属性配置的号码相同？干杯 .

    您似乎缺少源代码中的 GEODE_HOME 环境变量，这是启动期间服务器需要的，以便找到启动REST API所需的库，特别是 install-dir/tools/Extensions/geode-web-api-n.n.n.war . 您可以在Setup and Configuration找到有关此内容的更多详细信息 .

    希望这可以帮助 . 干杯 .
