java - Apache Geode 在 Java 应用程序内部启动定位器和服务器

Question

我是 Apache Geode 的新手，并尝试在我的 java 应用程序中运行定位器和服务器，但启动应用程序时出现异常。这是我用于启动定位器和服务器的代码:

public static void locatorStarter() {
    LocatorLauncher locatorLauncher = new LocatorLauncher.Builder()
            .setMemberName("locator1")
            .setPort(13334)
            .build();
    locatorLauncher.start();
}

public static void serverStarter() {
    ServerLauncher serverLauncher = new ServerLauncher.Builder()
            .setMemberName("server1")
            .setServerPort(40404)
            .build();
    serverLauncher.start();
}

当我从主函数调用这些方法时，出现以下异常:

导致此错误的原因是什么？如何解决？

启动服务器时，添加 start-locator 属性以在服务器进程中启动嵌入式定位器。有关该属性的更多信息，请参见文档。

ServerLauncher serverLauncher = new ServerLauncher.Builder()
        .setMemberName("server1")
        .setServerPort(40404)
        **.set("start-locator", "address[port1]")**
        .build();
    serverLauncher.start();
