### Deploying Multiple Dubbo Instances with Modules

Source: https://github.com/apache/dubbo-website/blob/master/content/en/overview/mannual/java-sdk/reference-manual/config/api/api.md

This example demonstrates how to configure and start two independent Dubbo instances using DubboBootstrap. Each instance is configured with a unique application name and uses modules to isolate service publishing and subscription. This setup ensures that even with identical service configurations, consumers are isolated.

```java
ServiceConfig<DemoService> service = new ServiceConfig<>();
service.setInterface(DemoService.class);
service.setRef(new DemoServiceImpl());

ReferenceConfig<DemoService> reference1 = new ReferenceConfig<>();
reference1.setInterface(DemoService.class);

ReferenceConfig<DemoService> reference2 = new ReferenceConfig<>();
reference2.setInterface(DemoService.class);

// Create a launcher (automatically create a new ApplicationModel)
DubboBootstrap bootstrap1 = DubboBootstrap.newInstance();
// Specify application name
bootstrap1.application(new ApplicationConfig("dubbo-demo-app-1"))
	.registry(new RegistryConfig("nacos://localhost:8848"))
	// Create a module
	.newModule()
		// Publish service within the module
		.service(service)
	.endModule()
	// Create another module
	.newModule()
		// Subscribe to service within the module
		.reference(reference1)
	.endModule()
	.start();

// Create another launcher (automatically create a new ApplicationModel)
DubboBootstrap bootstrap2 = DubboBootstrap.newInstance();
// Specify application name
bootstrap2.application(new ApplicationConfig("dubbo-demo-app-2"))
	.registry(new RegistryConfig("nacos://localhost:8848"))
	// Create a module
	.newModule()
		// Subscribe to service within the module
		.reference(reference2)
	.endModule()
	.start();

// stub1 and stub2 are two independent subscriptions, completely isolated

// Subscribed stub
DemoService stub1 = reference1.get();
System.out.println(stub1.sayHello("Hello World!"));

// Subscribed stub
DemoService stub2 = reference2.get();
System.out.println(stub2.sayHello("Hello World!"));

bootstrap1.stop();
bootstrap2.stop();
```
