SpringBoot2集成Dubbo

使用的SpringBoot的版本是

2.1.3.RELEASE

　首先添加Dubbo相关依赖

<!--引入dubbo的依赖 -->
        <dependency>
            <groupId>com.alibaba.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>0.2.0</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>dubbo</artifactId>
            <version>2.6.4</version>
            <optional>true</optional>
        </dependency>
        <!-- 引入zookeeper的依赖 -->
        <dependency>
            <groupId>com.101tec</groupId>
            <artifactId>zkclient</artifactId>
            <version>0.10</version>
        </dependency>

然后新建项目-api项目-该项目需要一个接口即可，然后使用maven命令达成jar包，安装到本地仓库中

package com.voole.service;

public interface IndexService {
    
    public String index(String message);

}

新建生产者项目，添加dubbo相关依赖，

添加api包的依赖，添加接口实现类

package com.voole.platform.app;


import org.springframework.stereotype.Component;

import com.alibaba.dubbo.config.annotation.Service;
import com.voole.service.IndexService;

@Component
@Service(version="1.0.0",interfaceClass=IndexService.class)
public class IndexServiceImpl implements IndexService {
    
    @Override
    public String index(String message) {
        System.out.println(message);
        return message+"-yes";
    }

}

启动类中添加注解信息

@EnableDubbo

配置文件中添加配置信息

dubbo.registry.protocol=zookeeper
dubbo.registry.address=127.0.0.1:2181
dubbo.registry.id=dubbo-provider
dubbo.application.name=dubbo-provider
dubbo.scan.base-packages=com.voole.business
dubbo.protocol.port=20882
dubbo.protocol.name=dubbo
dubbo.protocol.status=server
dubbo.protocol.id=dubbo

新建消费者项目，添加dubbo依赖，api项目包依赖

配置文件中添加配置信息

# dubbo config
dubbo.registry.protocol=zookeeper
dubbo.registry.address=127.0.0.1:2181
dubbo.registry.id=dubbo-consumer
dubbo.application.name=dubbo-consumer

启动类中添加相关注解信息

@EnableDubbo
@DubboComponentScan(basePackages= {"com.voole.service"})

之后在想调用的地方添加

@Reference(check=false)
private IndexService indexService;

就可以使用了。（zk用的是本地，测试的时候记得启动zk）
