springboot+dubbo+nacos整合
1、创建maven项目
dubbo-nacos-demo
2、父工程引入依赖
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

3、创建子工程dubbo-provide
引入依赖
<project xmlns="http://maven.apache.org/POM/4.0.0"

xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

新建配置文件application.yml
nacos:
config:
server-addr: localhost:8848
spring:
application:
name: dubbo-provide
dubbo:
application:
name: ${spring.application.name}
registry:
address: nacos://${nacos.config.server-addr}
scan:
base-packages: com.zmq.service
protocol:
name: dubbo
port: 20881
创建启动类
package com.zmq;
import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableDubbo
public class DubboProvideApplication {
public static void main(String[] args) {
SpringApplication.run(DubboProvideApplication.class);
}
}
创建service接口
package com.zmq.service;
public interface ProvideService {
String sayHello(String word);
}
创建service接口实现类，注意这里的service注解是dubbo的注解
package com.zmq.service.impl;
import com.zmq.service.ProvideService;
import org.apache.dubbo.config.annotation.Service;
@Service
public class ProvideImpl implements ProvideService {
public String sayHello(String word) {
return word;
}
}
3、创建dubbo-consumer模块
引入依赖
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

创建application.yml配置文件
server:
address:
port: 8081
spring:
application:
name: dubbo-consumer
nacos:
config:
server-addr: localhost:8848
dubbo:
registry:
address: nacos://${nacos.config.server-addr}
application:
name: ${spring.application.name}
创建启动类
package com.zmq;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class dubboConsumerApplication {
public static void main(String[] args) {
SpringApplication.run(dubboConsumerApplication.class);
}
}
创建controller调用服务
package com.zmq.controller;
import com.zmq.service.ProvideService;
import org.apache.dubbo.config.annotation.Reference;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class ConsumerController {
@Reference
ProvideService provideService;
@RequestMapping("sayHello")
public String sayHello(){
return provideService.sayHello("我爱你");
}
}
4、浏览器查看结果
在浏览器输入localhost:8081/sayHello,即可看到输出的话
5、启动nacos后可在服务列表看到注册的服务
