SpringCloud H系列 alibaba 2.1.1 (一) nacos1.X 注册中心 服务端

1.首先搭建nacos

参考文章 : docker 安装 nacos 1.X

2.项目结构

• 使用依赖
• springboot 2.2.2.RELEASE
• springcloud Hoxton.RELEASE
• springcloud alibaba 2.1.1.RELEASE

 

3.父工程创建

pom.xml  工程文件

    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.2.2.RELEASE</version>
        <relativePath/> <!-- lookup parent from repository -->
    </parent>

    <groupId>com.alibaba</groupId>
    <artifactId>spring-cloud-hoxton</artifactId>
    <packaging>pom</packaging>
    <version>1.0</version>

    <properties>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
        <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding>
        <java.version>1.8</java.version>
        <springcloud.version>Hoxton.RELEASE</springcloud.version>
        <springcloud.alibaba.version>2.1.1.RELEASE</springcloud.alibaba.version>
        <lombok.version>1.18.2</lombok.version>
    </properties>

    <modules>
        <!-- spring cloud alibaba专题-->
        <module>alibaba-nacos-discovery-server</module> <!-- 使用Nacos实现服务注册与发现：服务提供方 -->
        <module>alibaba-nacos-discovery-client</module> <!-- 使用Nacos实现服务注册与发现：服务消费方 -->
    </modules>

    <dependencyManagement>
        <dependencies>
            <dependency>
                <groupId>org.springframework.cloud</groupId>
                <artifactId>spring-cloud-dependencies</artifactId>
                <version>${springcloud.version}</version>
                <type>pom</type>
                <scope>import</scope>
            </dependency>
            <dependency>

            <artifactId>lombok</artifactId>
            <version>${lombok.version}</version>
            <optional>true</optional>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>

            </plugin>
        </plugins>
    </build>

4.创建服务端子工程 alibaba-nacos-discovery-server

pom.xml  工程文件

    <parent>
        <groupId>com.alibaba</groupId>
        <artifactId>spring-cloud-hoxton</artifactId>
        <version>1.0</version>
    </parent>

    <artifactId>alibaba-nacos-discovery-server</artifactId>
    <version>1.0</version>
    <packaging>jar</packaging>

    <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>
    </dependencies>

application.yml   配置文件

spring:
  application:
    # 应用名称
    name: alibaba-nacos-discovery-server
  cloud:
    nacos:
      discovery:
        # nacos注册中心地址
        server-addr: 192.168.1.141:8848
server:
  port: 8001

TestApplication.java  启动类

@EnableDiscoveryClient //启动注册中心客户端 注册到nacos
@SpringBootApplication
public class TestApplication {

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

}

TestController.java  测试类(供客户端调用的接口编写)

@Slf4j
@RestController
public class TestController {

    @GetMapping("/test")
    public String hello(@RequestParam String name) {
        log.info("调用 name => " + name);
        return "参数 => " + name;
    }

}

启动server端后查看nacos服务列表是否注册成功

nacos服务列表  服务名与我们设置的一致  表示注册成功

接下来调用服务端暴露的业务接口

返回值正确  nacos服务端完成
