1.創(chuàng)建一個(gè)maven空項(xiàng)目
maven空項(xiàng)目.png
該項(xiàng)目包含api敌买、consumer、provider三個(gè)子模塊，均為springboot模塊檀何。
2.在api模塊創(chuàng)建服務(wù)接口
package com.cz.czapi.service;
public interface OrderService {
Integer add(int cost);
}
該服務(wù)模擬提供訂單服務(wù)重虑。
3.在提供者服務(wù)里面實(shí)現(xiàn)服務(wù)践付。
（1）首先引入api模塊以及dubbo
<!--引入api-->
<dependency>
<groupId>com.cz</groupId>
<artifactId>cz-api</artifactId>
<version>0.0.1-SNAPSHOT</version>
<scope>compile</scope>
</dependency>
<!--引入dubbo環(huán)境-->
<dependency>
<groupId>com.alibaba.boot</groupId>
<artifactId>dubbo-spring-boot-starter</artifactId>
<version>0.2.0</version>
</dependency>
(2)配置dubbo
dubbo:
application:
name: dubbo-provider
registry:
address: 192.168.100.250:2181
protocol: zookeeper
check: false
protocol:
name: dubbo
port: 30003
monitor:
protocol: register
consumer:
check: false
timeout: 3000
server:
port: 8061
dubbo.registry.address修改為自己的zk地址
（3）啟動(dòng)類啟用dubbo（@EnableDubbo注解類）
package com.cz.czprovider;
import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@EnableDubbo
@SpringBootApplication
public class CzProviderApplication {
public static void main(String[] args) {
SpringApplication.run(CzProviderApplication.class, args);
}
}
(4)實(shí)現(xiàn)服務(wù)
package com.cz.czprovider.service.impl;
import com.alibaba.dubbo.config.annotation.Service;
import com.cz.czapi.service.OrderService;
/**
* @program: cz-parent
* @description:
* @author: shuonar
* @create: 2020-12-23 17:16
**/
@Service
public class OrderServiceImpl implements OrderService {
private final Integer totalCost = 500;
@Override
public Integer add(int cost) {
return totalCost + cost;
}
}
注意：實(shí)現(xiàn)一定引入dubbo的Service注解，引入Spring的Service的將會(huì)導(dǎo)致服務(wù)提供者不存在
3.消費(fèi)者準(zhǔn)備
（1）引入dubbo和api
<!--引入api模塊-->
<dependency>
<groupId>com.cz</groupId>
<artifactId>cz-api</artifactId>
<version>0.0.1-SNAPSHOT</version>
<scope>compile</scope>
</dependency>
<!--引入dubbo環(huán)境-->
<dependency>
<groupId>com.alibaba.boot</groupId>
<artifactId>dubbo-spring-boot-starter</artifactId>
<version>0.2.0</version>
</dependency>
(2)配置yaml
dubbo:
application:
name: dubbo-consumer
registry:
address: 192.168.100.250:2181
protocol: zookeeper
check: false
monitor:
protocol: register
consumer:
check: false
timeout: 3000
server:
port: 8062
(3)消費(fèi)服務(wù)
package com.cz.czconsumer.service.impl;
import com.alibaba.dubbo.config.annotation.Reference;
import com.alibaba.dubbo.config.annotation.Service;
import com.cz.czapi.service.OrderService;
import com.cz.czconsumer.service.WorkService;
/**
* @program: cz-parent
* @description:
* @author: shuonar
* @create: 2020-12-23 17:05
**/
@Service
public class WorkServiceImpl implements WorkService {
@Reference
private OrderService orderService;
//日志服務(wù)...
//優(yōu)惠券服務(wù)
@Override
public Integer getCost(int a) {
Integer result = null;
try {
result = orderService.add(a);
}catch (Exception e){
e.printStackTrace();
}
return result;
}
}
package com.cz.czconsumer.service;
public interface WorkService {
Integer getCost(int a);
}
(4)controller類
package com.cz.czconsumer.controller;
import com.cz.czconsumer.service.WorkService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
* @program: cz-parent
* @description:
* @author: shuonar
* @create: 2020-12-23 17:11
**/
@RestController
public class WorkController {
@Autowired
private WorkService workService;
@RequestMapping("/getCost")
public String getCost(int a){
return "該工單總共消費(fèi) ：" + workService.getCost(a);
}
}
4.效果

出現(xiàn)該效果表示成功調(diào)用缺厉。
