provider的application.yml配置文件
server:
port: 9000
spring:
application:
name: *-provider
dubbo:
application:
name: dubbo-*-provider
protocol:
name: dubbo
port: 20880
registry:
protocol: zookeeper
address: 127.0.0.1:2181
timeout: 20000
file: ./dubbo-provider-*
version: 1.0.0
scan:
base-packages:
- com.milky.provider
enable-file-cache: false
consumer的application.yml配置文件
server:
port: 8088
spring:
application:
name: *-webadmin
dubbo:
application:
name: dubbo-consumer-webadmin
enable-file-cache: false
registry:
protocol: zookeeper
address: 127.0.0.1:2181
timeout: 60000
file: ./dubbo-consumer-webadmin
version: 1.0.0
scan:
base-packages:
- com.milky.webadmin
provider的启动类
package com.milky.provider;
import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableDubbo
public class ProviderApplication {
public static void main(String[] args) {
SpringApplication.run(ProviderApplication.class,args);
}
}
consumer的启动类
package com.milky.webadmin;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class WebAdminApplication {
public static void main(String[] args) {
SpringApplication.run(WebAdminApplication.class,args);
}
}
一些注意事项
启动类需要加@EnableDubbo
服务实现类需要加@DubboService，指定向注册中心暴露该类，消费者可以调用其中的方法
订阅service要用到@DubboReference注入api模块的接口
