自從Dubbo支持SpringBoot後，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
com.alibaba.boot
dubbo-spring-boot-starter
0.2.0
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;
@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));
}
}
