这篇文章主要介绍了springcloud如何使用dubbo开发rpc服务及调用,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
spring cloud中基于springboot开发的微服务，是基于http的rest接口，也可以开发基于dubbo的rpc接口。
一，创建goodsService模块
1， 在创建的goodsService模块中再创建goodsServiceApi和goodsServiceServer模块
2，在oodsServiceApi模块中定义接口 ，goodsServiceServer用于接口实现
3，goodsServiceServer模块中pom文件引入相关依赖
<dependencies>
<dependency>
<groupId>net.biui</groupId>
<artifactId>goods-service-api</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-dubbo</artifactId>
</dependency>
</dependencies>
4，goodsServiceServer中添加配置
spring:
application:
name: goods-service
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
namespace: c22e5019-0bee-43b1-b80b-fc0b9d847501
dubbo:
registry:
address: nacos://127.0.0.1:8848
scan:
base-packages: net.biui.impl
protocol:
port: 20881
name: dubbo
5，goodsServiceServer编写接口实现
@org.apache.dubbo.config.annotation.Service
public class GoodsImpl implements GoodsApi {
public String getGoodsName() {
return "商品一";
}
}
6，goodsServiceServer编写启动类
@SpringBootApplication
@EnableDiscoveryClient
public class GoodsServiceServerApplication {
public static void main(String[] args) {
SpringApplication.run(GoodsServiceServerApplication.class, args);
}
}
启动后，dubbo服务会自动注册到nacos服务发现中心
二，创建调用dubbo服务的模块
1，new -> module -> 填写信息 -> finish
2，添加pom依赖
<dependencies>
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
</dependency>
<dependency>
<groupId>com.alibaba.cloud</groupId>
<artifactId>spring-cloud-starter-dubbo</artifactId>
</dependency>
<dependency>
<groupId>net.biui</groupId>
<artifactId>goods-service-api</artifactId>
<version>1.0-SNAPSHOT</version>
</dependency>
</dependencies>
3，添加配置
spring:
application:
name: demo-dubbo
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
namespace: c22e5019-0bee-43b1-b80b-fc0b9d847501
4，编写controller调用dubbo服务
@RestController
@RequestMapping("/demo")
public class demoController {
@org.apache.dubbo.config.annotation.Reference
GoodsApi goodsApi;
@GetMapping("/test")
public String test(){
return "test " + goodsApi.getGoodsName();
}
}
5，编写启动类
@SpringBootApplication
@EnableDiscoveryClient
public class demoDubboApplication {
public static void main(String[] args) {
SpringApplication.run(demoDubboApplication.class, args);
}
}
启动后，demo-dubbo服务也会自动注册到nacos（因为nacos.register.enable默认为true，即代表自动注册，可以只订阅，不注册），对应接口返回了dubbo服务返回的信息！
