spring cloud nacos服务搭建
基于nacos搭建的父项目、spring cloud nacos provider（服务提供者）、spring cloud nacos consumer（服务消费者）结构：
1. 创建一个maven父项目。
maven父项目包含springcloudnacos-provider（服务提供者）、springcloudnacos-consumer（服务消费者）两个子模块。父模块下的src可以删除。
maven父项目的pom.xml：
4.0.0
org.springframework.boot
spring-boot-starter-parent
2.2.4.RELEASE
com.example
springcloudnacos
0.0.1-SNAPSHOT
springcloudnacos
Demo project for Spring Boot
pom

2.2.4.RELEASE
Hoxton.RELEASE
2.2.0.RELEASE
springcloudnacos-provider
springcloudnacos-consumer
org.springframework.boot
spring-boot-starter
org.springframework.boot
spring-boot-starter-test

pom
import
org.springframework.boot
spring-boot-maven-plugin
org.apache.maven.plugins

true
2. 服务提供者：springcloudnacos-provider
（1）spring cloud nacos provider项目的pom.xml
4.0.0
com.example
springcloudnacos
0.0.1-SNAPSHOT
com.example
springcloudnacos-provider
0.0.1-SNAPSHOT
springcloudnacos-provider
Demo project for Spring Boot
1.8
org.springframework.boot
spring-boot-starter
org.springframework.boot
spring-boot-starter-web
org.springframework.boot
spring-boot-starter-test
test
com.alibaba.cloud
spring-cloud-starter-alibaba-nacos-discovery
com.alibaba.cloud
spring-cloud-starter-alibaba-nacos-config
org.apache.maven.plugins
maven-surefire-plugin
true
（2）spring cloud nacos provider服务的启动类
package com.example.springcloudnacosprovider;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
@SpringBootApplication
@EnableDiscoveryClient
public class SpringcloudnacosProviderApplication {
public static void main(String[] args) {
SpringApplication.run(SpringcloudnacosProviderApplication.class, args);
}
}
（3）spring cloud nacos provider服务的yml配置
spring:
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
application:
name: nacos-provider
server:
port: 8090
（4）spring cloud nacos provider服务的测试类
package com.example.springcloudnacosprovider.controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class NacosProviderController {
@RequestMapping("/testNacosProvider")
public String testNacosProvider(){
return "this is my nacos provider！";
}
}
（5）spring cloud nacos provider服务测试
（6）spring cloud nacos provider服务在nacos上的注册（nacos服务注册中心）
3. 服务消费者：springcloudnacos-consumer
（1）spring cloud nacos consumer服务的pom.xml
4.0.0
com.example
springcloudnacos
0.0.1-SNAPSHOT
com.example
springcloudnacos-consumer
0.0.1-SNAPSHOT
springcloudnacos-consumer

（2）spring cloud nacos consumer服务的启动类
package com.example.springcloudnacosconsumer;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.cloud.client.discovery.EnableDiscoveryClient;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;
@SpringBootApplication
@EnableDiscoveryClient
public class SpringcloudnacosConsumerApplication {
public static void main(String[] args) {
SpringApplication.run(SpringcloudnacosConsumerApplication.class, args);
}
@Bean
@LoadBalanced
public RestTemplate restTemplate(){
return new RestTemplate();
}
}
（3）spring cloud nacos consumer服务的yml配置
spring:
cloud:
nacos:
discovery:
server-addr: 127.0.0.1:8848
application:
name: nacos-consumer
server:
port: 8091
（4）spring cloud nacos consumer服务的测试类
package com.example.springcloudnacosconsumer.controller;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;
@RestController
public class NacosConsumerController {
private RestTemplate restTemplate;
@Autowired
public NacosConsumerController(RestTemplate restTemplate){
this.restTemplate = restTemplate;
}
@RequestMapping("/testNacosConsumer")
public String testNacosConsumer(){
return restTemplate.getForObject("http://nacos-provider/testNacosProvider",String.class);
}
}
（5）spring cloud nacos consumer服务测试
