首先新建父工程

添加依赖如下：

   <dependencies>
            <!-- spring-cloud-alibab-dependencies -->
            <dependency>
                <groupId>com.alibaba.cloud</groupId>
                <artifactId>spring-cloud-alibaba</artifactId>
                <version>2.1.0.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <!-- spring-cloud-dependencies -->
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>Greenwich.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

            <!-- spring-boot-dependencies -->
            <dependency>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-dependencies</artifactId>
                <version>2.1.3.RELEASE</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>

接着新建提供者模块依赖于父工程

依赖如下：

    <dependencies>

    <dependency>
        <groupId>com.alibaba.cloud</groupId>
        <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.cloud</groupId>
        <artifactId>spring-cloud-starter-openfeign</artifactId>
    </dependency>

    </dependencies>

application.yml配置文件如下：

server: port: 56010 spring: application: name: quickstart-provider cloud: nacos: discovery: server-addr: 127.0.0.1:8848 logging: level: root: info org.springframework: info

新建个controller，使用api测试

package com.ckf.nacos.controller; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; /** * @author serene * @date 2020/8/22 16:18 */ @RestController public class ProviderController { private static final Logger logger = LoggerFactory.getLogger(ProviderController.class); @GetMapping("/service") public String service(){ logger.info("provider invoke"); return "provider invoke"; } }

启动类

package com.ckf.nacos; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.cloud.openfeign.EnableFeignClients; /** * @EnableDiscoveryClient 服务发现客户端 * @EnableFeignClients feign客户端 进行远程调用 * @author: serene * @date: 2020/8/022 16:26 * @description: */ @SpringBootApplication @EnableDiscoveryClient @EnableFeignClients public class ProviderApplication { public static void main(String[] args) { System.out.println("服务提供者启动成功"); SpringApplication.run(ProviderApplication.class, args); } }

接着新建消费者模块依赖于父工程

新建feign客户端

package com.ckf.nacos.client; import org.springframework.cloud.openfeign.FeignClient; import org.springframework.web.bind.annotation.GetMapping; /**@FeignClient 调用服务的名称 yml配置文件的服务名 * @author serene * @date 2020/8/22 16:40 */ @FeignClient(value = "quickstart-provider") public interface ProviderClient { /** * 调用服务的方法 * @return */ @GetMapping("/service") public String service(); }

新建controller

package com.ckf.nacos.controller; import com.ckf.nacos.client.ProviderClient; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.beans.factory.annotation.Autowired; import org.springframework.web.bind.annotation.GetMapping; import org.springframework.web.bind.annotation.RestController; /** * @author serene * @date 2020/8/22 16:46 */ @RestController public class ConsumerController { private static final Logger logger = LoggerFactory.getLogger(ConsumerController.class); /** * 动态代理对象，内部远程调用服务生产者 */ @Autowired private ProviderClient providerClient; @GetMapping("/service") public String service(){ logger.info("consumer invoke"); //远程调用
        String service = providerClient.service(); return "comsumer invoke "+"|"+" + service"; } }

application.yml配置如下：

server:
  port: 56020


spring:
  application:
    name: quickstart-consumer
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8848
logging:
  level:
    root: info
    org.springframework: info

服务消费者启动类如下：

package com.ckf.nacos; import com.ckf.nacos.controller.ConsumerController; import org.slf4j.Logger; import org.slf4j.LoggerFactory; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.cloud.client.discovery.EnableDiscoveryClient; import org.springframework.cloud.openfeign.EnableFeignClients; /** * @EnableDiscoveryClient 服务发现客户端 * @EnableFeignClients feign客户端 进行远程调用 * @author: serene * @date: 2020/8/022 16:26 * @description: */ @SpringBootApplication @EnableDiscoveryClient @EnableFeignClients public class ConsumerApplication { private static final Logger logger = LoggerFactory.getLogger(ConsumerController.class); public static void main(String[] args) { logger.info("服务消费者启动成功"); System.out.println("服务消费者启动成功"); SpringApplication.run(ConsumerApplication.class, args); } }
