SpringBoot之整合Dubbo

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

<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter</artifactId>
</dependency>
<!-- dubbo的依赖 -->
<!-- https://mvnrepository.com/artifact/org.apache.dubbo/dubbo-spring-boot-starter -->
<dependency>
<groupId>org.apache.dubbo</groupId>
<artifactId>dubbo-spring-boot-starter</artifactId>
<version>2.7.6</version>
</dependency>


<!-- zk的依赖 -->
<dependency>
<groupId>org.apache.dubbo</groupId>
<artifactId>dubbo-dependencies-zookeeper</artifactId>
<version>2.7.6</version>
<type>pom</type>
<exclusions>
<exclusion>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
</exclusion>
</exclusions>
</dependency>

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

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
4
5
6
7
8
9
10
11
12
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)

1.导入Maven依赖

package com.dubbo.blog;

import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
public class DubboConsumerApplication {

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

}

1

spring.application.name=blog-dubbo-consumer
dubbo.registry.address=zookeeper://127.0.0.1:2181
server.port=7000

3.编写Controller

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
