Apache Dubbo Demo
创建父工程 apache-dubbo-demo
一、项目结构
二、pom.xml
统一依赖管理 apache-dubbo-dependencies
一、项目结构
二、pom.xml
服务提供者 apache-dubbo-provider
一、项目结构
二、apache-dubbo-provider/pom.xml
三、apache-dubbo-provider-api/pom.xml
四、EchoService
package com.cnbai.apache.dubbo.provider.api;
/**
* 测试动态化配置
*
* @author bai
* @since 2020/5/12
*/
public interface EchoService {
/**
* 测试 nacos 动态化配置文件
*
* @param string string
* @return {@link String}
* @author bai
* @since 2020/5/12
*/
String echo(String string);
}
五、apache-dubbo-provider-service/pom.xml
六、EchoServiceImpl
package com.cnbai.apache.dubbo.provider.service;
import com.cnbai.apache.dubbo.provider.api.EchoService;
import org.apache.dubbo.config.annotation.Service;
import org.springframework.beans.factory.annotation.Value;
/**
* 测试负载均衡,动态化配置
*
* @author bai
* @since 2020/5/12
*/
@Service(version = "1.0.0")
public class EchoServiceImpl implements EchoService {
/**
* 测试负载均衡
*/
@Value("${dubbo.protocol.port}")
private String port;
/**
* 测试负载均衡,动态化配置
*/
@Override
public String echo(String string) {
return "Echo Hello Dubbo " + string + " i am from port: " + port;
}
}
七、ProviderApplication
package com.cnbai.apache.dubbo.provider;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* 服务提供者启动类
*
* @author bai
* @since 2020/5/12
*/
@SpringBootApplication
public class ProviderApplication {
public static void main(String[] args) {
SpringApplication.run(ProviderApplication.class, args);
}
}
八、application.yml
spring:
application:
name: dubbo-provider
# 定义两个 id 相同的 bean 起冲突时，以后定义的为主
main:
allow-bean-definition-overriding: true
dubbo:
scan:
base-packages: com.cnbai.apache.dubbo.provider.service
protocol:
name: dubbo
# 自动分配端口号 20880
# port: -1
port: 20881
serialization: kryo
registry:
address: nacos://192.168.205.130:8848
# 负载均衡策略 random 随机(默认)，roundrobin 轮循，leastactive 最少活跃调用数，consistenthash 一致性 Hash
provider:
loadbalance: roundrobin
服务消费者 apache-dubbo-consumer
一、项目结构
二、pom.xml
三、EchoController
package com.cnbai.apache.dubbo.consumer.controller;
import com.cnbai.apache.dubbo.provider.api.EchoService;
import org.apache.dubbo.config.annotation.Reference;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.cloud.context.config.annotation.RefreshScope;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;
/**
* 测试负载均衡,动态化配置
*
* @author bai
* @since 2020/5/12
*/
@RefreshScope
@RestController
public class EchoController {
@Reference(version = "1.0.0")
private EchoService echoService;
/**
* 测试动态化配置
*/
@Value("${user.name}")
private String username;
/**
* 测试 nacos 动态化配置
*
* @param string string
* @author cnbai
* @return {@link String}
* @since 2020/5/12
*/
@GetMapping(value = "/echo/{string}")
public String echo(@PathVariable String string) {
return echoService.echo(string) + " " + username;
}
}
四、ConsumerApplication
package com.cnbai.apache.dubbo.consumer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
/**
* 服务消费者启动类
*
* @author bai
* @since 2020/5/12
*/
@SpringBootApplication
public class ConsumerApplication {
public static void main(String[] args) {
SpringApplication.run(ConsumerApplication.class, args);
}
}
五、bootstrap.properties
##########################################################################
#
# Spring Boot 配置文件的加载顺序：

# > application.yml
#
# 注：bootstrap.properties 配置为最高优先级一定会加载

spring.application.name=dubbo-consumer-config
spring.cloud.nacos.config.server-addr=192.168.205.130:8848
spring.cloud.nacos.config.file-extension=yaml
六、dubbo-consumer-config.yaml
yml文件都写在Nacos配置管理中,Nacos中的配置不能写注释，要删掉
