How is Dubbo utilized in projects?

When using Dubbo in a project, the following steps need to be taken:

1. Add the dependency of Dubbo: Include the Dubbo dependency in the project’s pom.xml file.

<dependency>
    <groupId>com.alibaba</groupId>
    <artifactId>dubbo</artifactId>
    <version>2.7.0</version>
</dependency>

1. Customer support

@Service
public interface UserService {
    User getUserById(String id);
}

1. Implementing Dubbo service interfaces: Writing the implementation class of the service interface.

@Service
public class UserServiceImpl implements UserService {
    @Override
    public User getUserById(String id) {
        // 实现具体逻辑
    }
}

1. Setting up Dubbo service provider: Configure Dubbo service provider in the project configuration file (such as application.properties).

# 服务提供者应用名称
dubbo.application.name=your_application_name
# 注册中心地址
dubbo.registry.address=zookeeper://127.0.0.1:2181
# 服务协议
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880

1. Configure Dubbo service consumers: Configure Dubbo service consumers in the project’s configuration file.

# 服务消费者应用名称
dubbo.application.name=your_application_name
# 注册中心地址
dubbo.registry.address=zookeeper://127.0.0.1:2181

1. Can you provide a reference for that?

@Reference
private UserService userService;

1. Start Dubbo service: Initialize Dubbo service provider when the project is started.

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

The above are the basic steps for using Dubbo, and the specific configuration and usage can be adjusted according to the project’s needs.
