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，但是当我启动应用程序时会出现异常。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main函数调用这些方法时，我得到以下异常：

导致此错误的原因是什么？如何解决？
答案 0 :(得分：0)
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。更多关于文档中的属性。
ServerLauncher serverLauncher = new ServerLauncher.Builder()
.setMemberName("server1")
.setServerPort(40404)
**.set("start-locator", "address[port1]")**
.build();
serverLauncher.start();
