1. Download nacos

Select the nacos download that matches the springcloud version

Release Notes · alibaba/spring-cloud-alibaba Wiki · GitHub

 Select the zip package in the windows environment. Unzip it after downloading.

2. Modify the configuration and start nacos

1. Direct boot

Enter the decompressed bin directory, edit startup.cmd, modify the set MODE line to set MODE="standalone", and save.

Double-click startup.cmd or run it as an administrator.

You can check the log in bin/logs to see if the startup is successful.

2. Background start

Use the nssm tool to install nacos as a background service. nssm use refer to the link below.

How to deploy ES, Kibana, Logstash or other .bat files as Windows background services using nssm tools

 After starting, enter the address to access. Both username and password are nacos.

3. Configure nacos in springcloud

Code directory structure

1. springcloud configuration file pom

The overall configuration of the project determines the version of springcloud and the version of each component.

Just focus on <dependencyManagement>, which replaces <parent>.

The modules under <modules> are automatically added when the project adds modules.

2. Configuration of order-nacos order module

pom.xml

<?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"

            <artifactId>spring-boot-starter-web</artifactId>

            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>
    </dependencies>

</project>

application.yml

Service registration to nacos uses the value of application name by default

server: 
  port: 8020 
spring: 
  application: 
    name: order-service 
  cloud: 
    nacos: 
      server-addr: 127.0.0.1:8848 
      discovery: 
        username: nacos 
        password: nacos 
# namespace: public #Service classification management default public 
# ephemeral: false # Permanent instance defaults to true Temporary instance 
# service: default ${spring.application.name} 
# group: finer classification management 
# weight: #load balancing weight 
# metadata: metadata can be extended according to the source code

3. Configuration of stock-service inventory module

The pom.xml is consistent with the order module, and the application.yml only needs to change the port to 8021.

4. Code

OrderApplication.java

Where @LoadBalanced is the default load balancing call of nacos. Analyze the service name to obtain ip, port

package com.wind.order;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.cloud.client.loadbalancer.LoadBalanced;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;

/**
 * @author dongguanghui
 * @date 2023/5/15 17:51
 */
@SpringBootApplication
public class OrderApplication {

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

    @Bean
    @LoadBalanced
    public RestTemplate restTemplate(RestTemplateBuilder builder){
        RestTemplate restTemplate = builder.build();
        return restTemplate;
    }
}

OrderController.java

package com.wind.order.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;

/**
 * @author dongguanghui
 * @date 2023/5/15 17:47
 */
@RestController
@RequestMapping("/order")
public class OrderController {

    @Autowired
    private RestTemplate restTemplate;

    @RequestMapping("/add")
    public String add(){
        System.out.println("下单成功");
        String msg = restTemplate.getForObject("http://stock-service/stock/reduct", String.class);
        return "order success!" + msg;
    }

}

StockApplication.java

package com.wind.stock;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.web.client.RestTemplateBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.web.client.RestTemplate;

/**
 * @author dongguanghui
 * @date 2023/5/15 17:51
 */
@SpringBootApplication
public class StockApplication {
    public static void main(String[] args) {
        SpringApplication.run(StockApplication.class,args);
    }
}

StockController.java

package com.wind.stock.controller;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.client.RestTemplate;

/**
 * @author dongguanghui
 * @date 2023/5/15 17:47
 */
@RestController
@RequestMapping("/stock")
public class StockController {


    @Value("${server.port}")
    private String port;

    @RequestMapping("/reduct")
    public String reduct(){
        System.out.println("下单成功");
        return "reduct success!:"+port;
    }

}

4. Project start and operation

After the project starts, the service is registered to nacos.

The browser directly calls the interface. You can see that the background calls another service successfully through the service name
