This article introduces the relevant knowledge of "how to integrate Dubbo zookeeper in SpringBoot". In the operation process of actual cases, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

docker pull zookeeper

docker run --name zk01 -p 2181:2181 --restart always -d 2e30cac00aca

Zookeeper has been successfully launched.

Zookeeper Zookeeper is a distributed, open-source distributed application coordination service. It is a software that provides consistency services for distributed applications, including configuration maintenance, domain name services, distributed synchronization, group services, etc.

DubboDubbo is Alibaba's open source distributed service framework, which is characterized by a layered approach to architecture, which allows decoupling (or maximum loose coupling) between layers.

From the service model point of view, Dubbo adopts a very simple model, either the provider provides the service or the consumer consumes the service, so based on this, two roles of service provider and service consumer can be abstracted.

Client configuration:

startup class

@SpringBootApplicationpublic class ConsumerManagerApplication { public static void main(String[] args) { SpringApplication.run(ConsumerManagerApplication.class, args); }}

controller

@RestControllerpublic class ManagerController { @Reference ManagerService managerService; @RequestMapping("/hello") public String hello() { return managerService.hello(); }}

service(only need to be consistent with the interface of the service class, and the package name should also be consistent)

public interface ManagerService { public String hello();}

application.properties

dubbo.application.name=consumer-managerdubbo.registry.address=zookeeper://192.168.0.106:2181server.port=8081

Server configuration:

startup class

@SpringBootApplicationpublic class ProviderManagerApplication { public static void main(String[] args) { SpringApplication.run(ProviderManagerApplication.class, args); }}

service interface and implementation class

public interface ManagerService { public String hello();}@Servicepublic class ManagerServiceImpl implements ManagerService { @Override public String hello() { System.out.println("Client request incoming! "); return "xixi success !!! "; }}

application.properties

dubbo.application.name=provider-managerdubbo.registry.address=zookeeper://192.168.0.106:2181dubbo.scan.base-packages=com.hourui
