springcloud + nacos微服務(三)--其他普通服務

創建一個springboot項目,

引入依賴, 如下

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>

        <!--服務註冊與發現-->

        <!--服務遠程配置-->

            <artifactId>spring-cloud-starter-alibaba-nacos-config</artifactId>

                <type>pom</type>
                <scope>import</scope>
            </dependency>
        </dependencies>
    </dependencyManagement>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

新增一個配置文件

命名爲bootstrap.yml, 內容如下

spring:
  application:
    name: nacos-demo1
  profiles:
    active: dev #使用dev環境
  cloud:
    nacos:
      discovery:
        server-addr: 192.168.188.128:8848
      config:
        server-addr: 192.168.188.128:8848
        file-extension: yml
        namespace: 命名空間id

啓動類上加上註解

@EnableDiscoveryClient

 

創建一個測試類

package com.gw.nacosdemo1.controller;

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

@RestController
@RequestMapping("/test")
public class TestController {

	@Value("${test}")
	String test;

	@GetMapping
	public String read() {
		return test;
	}
}

 

創建遠端的配置文件

 nacos->配置管理->配置列表->dev中, 新增

Data ID  :  nacos-demo1-dev.yml   (命名規則: 服務名(nacos-gateway-demo1) +  -命名空間名稱(-dev) + .yml)

                 .yml不能漏

格式:  yaml

內容:

server:
  port: 10011
spring:
  cloud:
    nacos:
      discovery:
        namespace: b245fdbe-fbb5-48c7-96a4-7297a4fd408d
test: devdev  #用於驗證

 

ok  一個普通的微服務創建完成

啓動成功,  在nacos的服務管理->服務列表->dev中, 就能看到這個服務啦

 

實例訪問: http://localhost:10011/test

通過網關訪問: http://localhost:10010/nacos-demo1/test
