Kite的学习历程SpringCloud之基于Nacos的服务提供者的创建

Kite学习历程的第二十七天

1. Nacos的服务提供者

1.1 服务者cloudalibaba-provider-payment9001创建

1.1.1 修改pom.xml引入依赖文件

引入时应该在夫项目中引入
在dependencyManagement中进行引入

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

<dependencies>
        <!--nacos依赖的引入-->

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

        <!--引入自己创建的entities包-->
        <dependency>
            <groupId>cn.kitey.spring</groupId>
            <artifactId>cloud-api-commons</artifactId>
            <version>${project.version}</version>
        </dependency>

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--监控-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-actuator</artifactId>
        </dependency>
        <!--热部署-->
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-devtools</artifactId><!-- -->
            <scope>runtime</scope>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.projectlombok</groupId>
            <artifactId>lombok</artifactId>
            <optional>true</optional>
        </dependency>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        </dependency>
        <dependency>
            <groupId>org.springframework.cloud</groupId>
            <artifactId>spring-cloud-commons</artifactId>
            <version>2.2.1.RELEASE</version>
            <scope>compile</scope>
        </dependency>

    </dependencies>

1.1.2 创建application.yml配置文件

这些配置可以在spring或者nacos官网中进行查找

server:
  port: 9002

spring:
  application:
    name: nacos-payment-provider
  cloud:
    nacos:
      ##使用nacos的配置中心
      discovery:
        server-addr: localhost:8848
management:
  endpoints:
    web:
      exposure:
        include: '*'

1.1.3 创建主启动类

package cn.kitey.springcloud;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;

@SpringBootApplication
@EnableDiscoveryClient
public class NacosProviderApplication {

    public static void main(String[] args) {
        SpringApplication.run(NacosProviderApplication.class, args);
    }


}

1.1.4 创建controller进行测试

package cn.kitey.springcloud.controller;

import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class PaymentController {
    @Value("${server.port}")
    private String serverPort;

    @GetMapping(value = "/payment/nacos/{id}")
    public String getPayment(@PathVariable("id") Long id){
        return "nacos registry, serverPort: " + serverPort + "\t id: " + id;
    }
}

1.2 按照上面的方法创建第二个服务者实现集群cloudalibaba-provider-payment9002

2 在nacos注册中心进行查看

1. 注册中心访问地址：
   http://localhost:8848/nacos/index.html
   在服务列表进行查看
   同一个名字两个实例
   
2. 查看详情：
   可以到有两个端口9001， 9002 的服务器
   
3. 访问一下：
   http://localhost:9001/payment/nacos/1
   
   表明创建成功！
