SpringBoot 整合 Dubbo 進行分布式開發

---

 

自從Dubbo支持SpringBoot后，Dubbo與Spring的整合變得更加的簡單了，下面就是完整的步驟：

 

1. 引入依賴

<dependency>
    <groupId>com.alibaba.boot</groupId>
    <artifactId>dubbo-spring-boot-starter</artifactId>
    <version>0.2.0</version>
</dependency>

 

2. 在dubbo-api中定義model和service接口，model就是普通的POJO，service接口的代碼如下:

BounterService.java

package cn.bounter.dubbo.service;

import cn.bounter.dubbo.model.Bounter;

public interface BounterService {
    
    Bounter findById(long id);
}

 

3. 服務提供者實現接口並配置Dubbo

BounterServiceImpl.java

package cn.bounter.dubbo.service;


import java.util.Date;
import com.alibaba.dubbo.config.annotation.Service;
import cn.bounter.dubbo.model.Bounter;


//聲明為Dubbo服務
@Service
public class BounterServiceImpl implements BounterService {

    @Override
    public Bounter findById(long id) {
        //模擬訪問數據庫
        return new Bounter().setId(1L).setName("simon").setCreateTime(new Date()).setCreateBy(1L);
    }

}

 

application.properties

## Application
server.port=28080

## Dubbo
dubbo.application.name=dubbo-provider
dubbo.registry.address=zookeeper://47.98.151.249:2181
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880
dubbo.scan.basePackages=cn.bounter

 

4. 服務消費者配置Dubbo並調用Dubbo服務

application.properties

# Application
server.port=18080

## Dubbo
dubbo.application.name=dubbo-consumer
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.scan=cn.bounter

 

BounterController.java

package cn.bounter.dubbo.controller;


import org.springframework.web.bind.annotation.CrossOrigin;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import com.alibaba.dubbo.config.annotation.Reference;

import cn.bounter.dubbo.model.ResponseData;
import cn.bounter.dubbo.service.BounterService;

@RestController
@CrossOrigin
@RequestMapping("/api/bounter")
public class BounterController {
    
    @Reference private BounterService bounterService;


    @GetMapping("/{id}")
    public ResponseData<?> get(@PathVariable Long id) {
        return new ResponseData<>().success().data(bounterService.findById(id));
    }

}

 

這樣當你依次啟動dubbo-provider和dubbo-consumer之后，瀏覽器訪問http://localhost:18080/api/bounter/1就可以看到效果了
