一、下载Dubbo-Admin并导入本地
dubbo-admin地址为:
https://github.com/apache/dubbo-admin
官方文档:
https://github.com/apache/dubbo-admin/blob/develop/README_ZH.md
注意需要安装Zookeeper(因为Dubbo使用Zookeeper作为注册中心)
二、建立服务提供者(这里是我博客的一个子项目名为blog-dubbo-provider)
1.导入Maven依赖

2.编写启动类和配置文件
启动类:

12
| package com.dubbo.blog;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class DubboProviderApplication {
public static void main(String[] args) {
SpringApplication.run(DubboProviderApplication.class, args);
}
}
|
配置文件(application.properties):

| # Spring boot application
spring.application.name=blog-dubbo-provider
# Base packages to scan Dubbo Component: @org.apache.dubbo.config.annotation.Service
dubbo.scan.base-packages=com.dubbo.blog.provider.service.impl
# Dubbo Application
## The default value of dubbo.application.name is ${spring.application.name}
dubbo.application.name=${spring.application.name}
# Dubbo Protocol
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880
## Dubbo Registry
dubbo.registry.address=zookeeper://127.0.0.1:2181
server.port=7010
|
3.编写接口和对应的实现类
TestService:
1
2
3
4

| package com.dubbo.blog.provider.service;
public interface TestService {
String showName();
}
|
TestServiceImpl:

12
| package com.dubbo.blog.provider.service.impl;
import com.dubbo.blog.provider.service.TestService;
import org.apache.dubbo.config.annotation.Service;
@Service(version = "1.0.0")
public class TestServiceImpl implements TestService {
@Override
public String showName() {
return "HELLO DUBBO";
}
}
|
TestService2:
1
2
3
4
5
| package com.dubbo.blog.provider.service;
public interface TestService2 {
String showName();
}
|
TestService2Impl:
1
2
3

| package com.dubbo.blog.provider.service.impl;
import com.dubbo.blog.provider.service.TestService2;
import org.apache.dubbo.config.annotation.Service;
@Service(version = "1.0.0")
public class TestService2Impl implements TestService2 {
@Override
public String showName() {
return "HELLO TestService2";
}
}
|
4.启动主类并打开Dubbo-Admin
下图表示Ok
三、建立服务消费者(这里是我博客的一个子项目名为blog-dubbo-consumer)

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

2
3
| spring.application.name=blog-dubbo-consumer
dubbo.registry.address=zookeeper://127.0.0.1:2181

| package com.dubbo.blog;
import com.dubbo.blog.provider.service.TestService;
import com.dubbo.blog.provider.service.TestService2;
import org.apache.dubbo.config.annotation.Reference;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class TestDubboController {
@Reference(version = "1.0.0")
private TestService2 service2;
@Reference(version = "1.0.0")
private TestService service;
@GetMapping("test1")
public String test1() {
return service.showName();
}
@GetMapping("test2")
public String test2() {
return service2.showName();
}
}
|
4.切换到dubbo-admin看服务关系
5.可以请求Controller对应的url测试一下
