dubbo3适配springboot2.7.3

版本详细

<dependency>
    <groupId>org.apache.dubbo</groupId>
    <artifactId>dubbo</artifactId>
    <version>3.0.3</version>
</dependency>

<parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>
    <version>2.3.1.RELEASE</version>
</parent>

<properties>
    <!-- Spring Cloud Hoxton.SR8 依赖 -->
    <spring-cloud.version>Hoxton.SR8</spring-cloud.version>
    <!-- spring cloud alibaba 依赖 -->
    <spring-cloud-alibaba.version>2.2.4.RELEASE</spring-cloud-alibaba.version>
</properties>

1.创建dubboApi

package com.imooc.ecommerce.service;

/**
 * @author lan
 * @date 2024/3/6
 */
public interface DubboApiService {


   public String dubboTest(String arg);


}

2.创建provider

package com.imooc.ecommerce;

import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

/**
 * @author lan
 * @date 2023/12/30
 */
@EnableDiscoveryClient
@SpringBootApplication
@EnableDubbo
public class DubboProviderApplication {
    public static void main(String[] args) {
        SpringApplication.run(DubboProviderApplication.class, args);
    }

}

创建Dubboapi实现类这里要引入api模块

package com.imooc.ecommerce.service;


import org.apache.dubbo.config.annotation.DubboService;

/**
 * @author lan
 * @date 2024/3/6
 */
@DubboService
public class DubboServiceImpl implements DubboApiService {

    @Override
    public String dubboTest(String arg) {
        System.out.println("test success");
        return "test success";
    }
}

<dependency>
    <groupId>com.imooc.ecommerce</groupId>
    <artifactId>e-commerce-dubbo3-api</artifactId>
    <version>1.0-SNAPSHOT</version>
    <scope>compile</scope>
</dependency>

3.创建consumer

package com.imooc.ecommerce;

import org.apache.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

/**
 * @author lan
 * @date 2023/12/30
 */
@EnableDiscoveryClient
@SpringBootApplication
@EnableDubbo
public class DubboConsumerApplication {
    public static void main(String[] args) {
        SpringApplication.run(DubboConsumerApplication.class, args);
    }

}

4 consumer调用

package com.imooc.ecommerce;

import com.imooc.ecommerce.service.DubboApiService;
import org.apache.dubbo.config.annotation.DubboReference;
import org.junit.jupiter.api.Test;
import org.springframework.boot.test.context.SpringBootTest;

/**
 * @author lan
 * @date 2023/12/30
 */

@SpringBootTest
public class DubboConsumerApplicationTest {

    @DubboReference(url = "dubbo://192.168.31.24:20880/com.imooc.ecommerce.service.DubboApiService")
    private DubboApiService dubboApiService;


    @Test
    public void test() {
        String sss = dubboApiService.dubboTest("sss");
        System.out.println(sss);
    }
}
