接口

package fun.bo.api;/*** @author todoitbo* @date 2024/1/12*/
public interface TestDubboService {String sayHello(String name);
}

服务提供者

properties文件

# 服务端口
server.port=18081
# 应用程序名称
spring.application.name=dubbo-provider
# Dubbo服务扫描路径
dubbo.scan.base-packages=fun.bo# Dubbo 通讯协议
dubbo.protocol.name=dubbo
# Dubbo服务提供的端口， 配置为-1，代表为随机端口 默认20880
dubbo.protocol.port=-1## Dubbo 注册器配置信息
dubbo.registry.address=zookeeper://127.0.0.1:2181
dubbo.registry.file = ${user.home}/dubbo-cache/${spring.application.name}/dubbo.cache
dubbo.spring.provider.version = 1.0.0

实现类

package fun.bo.iml;import fun.bo.api.TestDubboService;
import org.apache.dubbo.config.annotation.DubboService;
import org.springframework.beans.factory.annotation.Value;/*** @author todoitbo* @date 2024/1/12*/
@DubboService(version = "${dubbo.spring.provider.version}")
public class TestDubboServiceImpl implements TestDubboService {@Overridepublic String sayHello(String name) {return "hello " + name;}
}

服务消费者

properties

# 服务端口
server.port=18084
#服务名称
spring.application.name=dubbo-spring-consumer
#服务版本号
dubbo.spring.provider.version = 1.0.0
#消费端注册器配置信息
dubbo.registry.address=zookeeper://127.0.0.1:2181
#dubbo.consumer.check=false
dubbo.registry.file = ${user.home}/dubbo-cache/${spring.application.name}/dubbo.cache

接口层

package fun.bo.controller;import fun.bo.api.TestDubboService;
import org.apache.dubbo.config.annotation.DubboReference;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;/*** @author todoitbo* @date 2024/1/12*/
@RestController
public class TestDubboController {@DubboReference(version = "${dubbo.spring.provider.version}")private TestDubboService testDubboService;@GetMapping("/test-dubbo/{name}")public String testDubbo(@PathVariable String name) {return testDubboService.sayHello(name);}
}
