spring boot 集成 dubbo

研究了两天终于搭建成功，记录一下，也分享一下。

1、项目结构

建了三个项目，结构仅供参考

api：公共接口

consumer：消费者

provider：提供者

2、配置文件：

pom文件，这里就只贴一下依赖

parent的pom


    <dependencies>

        <dependency>
            <groupId>com.alibaba.spring.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>2.0.0</version>
        </dependency>

        <dependency>
            <groupId>org.apache.zookeeper</groupId>
            <artifactId>zookeeper</artifactId>
            <version>3.4.11</version>
        </dependency>
        <dependency>
            <groupId>com.101tec</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.10</version>
        </dependency>
    </dependencies>

provide的pom

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.11</version>
      <scope>test</scope>
    </dependency>
    <dependency>
      <groupId>com.dong</groupId>
      <artifactId>api</artifactId>
      <version>1.0-SNAPSHOT</version>
    </dependency>
  </dependencies>

consumer的pom

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <dependency>
            <groupId>com.dong</groupId>
            <artifactId>api</artifactId>
            <version>1.0-SNAPSHOT</version>
            <scope>compile</scope>
        </dependency>

    </dependencies>

application.properties

provider

## Dubbo 服务提供者配置
# Base packages to scan Dubbo Components (e.g., @Service, @Reference)
spring.dubbo.scan.basePackages  = com.dong.serviceImpl
# Dubbo Config properties
## ApplicationConfig Bean
spring.dubbo.application.id = provider
spring.dubbo.application.name = provider
## ProtocolConfig Bean
spring.dubbo.protocol.id = dubbo
spring.dubbo.protocol.name = dubbo
spring.dubbo.protocol.port = 12345
## RegistryConfig Bean
spring.dubbo.registry.id = registry
spring.dubbo.registry.address = zookeeper://127.0.0.1:2181

server.port=8090

consumer

## Dubbo 服务提供者配置
# ApplicationConfig Bean
spring.dubbo.application.id = consumer
spring.dubbo.application.name = consumer
## ProtocolConfig Bean
spring.dubbo.protocol.id = dubbo
spring.dubbo.protocol.name = dubbo
spring.dubbo.protocol.port = 12345
spring.dubbo.registry.address = zookeeper://127.0.0.1:2181

server.port=8091

3、业务代码

api

定义公共接口

package com.dong.service;


public interface HelloService {

    public String sayHello(String name);
}

provider

定义接口实现，并暴露服务，两个service注解都不可少，第一个spring用，第二个dubbo用

package com.dong.serviceImpl;

import com.dong.service.HelloService;
import org.springframework.stereotype.Service;

@Service
@com.alibaba.dubbo.config.annotation.Service(interfaceClass = HelloService.class)
public class HelloServiceImpl implements HelloService {
    @Override
    public String sayHello(String name) {
        return "hello " + name;
    }
}

consumer

（1）开启dubbo配置，（不开启注解@Reference不生效）

package com.dong;

import com.alibaba.dubbo.spring.boot.annotation.EnableDubboConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
@EnableDubboConfiguration
public class ConsumerApplication {

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

}

（2）引用接口调用服务

package com.dong.controller;

import com.alibaba.dubbo.config.annotation.Reference;
import com.dong.service.HelloService;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TestController {

    @Reference
    HelloService helloService;

    @RequestMapping(value = "sayHello")
    public String sayHello(String name) {
        return helloService.sayHello(name);
    }
}

3、启动项目，检查服务是否注册成功。
