The SpringBoot project is changed to the SpringCloud project using nacos as the registry

This chapter explains how to change springboot to springcloud project without changing the original business and use nacos as the registration center

First download the nacos registration center on the official website. The startup.cmd file in the bin directory is the startup command. The default port number is 8888

Next, modify the original project dependencies

Add the springcloud dependency version in the parent dependency module. If there is no parent dependency, it is also specified in the project directly.

Specify the version first

<properties>
        <cloud.version>Hoxton.RELEASE</cloud.version>
        <alibaba.version>2.2.0.RELEASE</alibaba.version>
        <!--原有项目代码-->
</properties>

add dependencies

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

Add nacos dependencies to subprojects

 <!-- 服务注册 -->
        <dependency>
            <groupId>com.alibaba.cloud</groupId>
            <artifactId>spring-cloud-starter-alibaba-nacos-discovery</artifactId>
        </dependency>

Startup class annotation

@EnableDiscoveryClient

Add in the application configuration file

Specify the naocs address, and the server name

spring:
  cloud:
    nacos:
      discovery:
        server-addr: 127.0.0.1:8888
  application:
    name: lzq-v587

After starting the project at this time, after starting naocs, log in to the nacos website

http://localhost:8888/nacos ; both account and password are nacos

You can see the current service in the service list; nacos is lazy loaded, you need to access the service first, and it will be displayed in naocs
