从0到1搭建一个SpringCloud项目从0到1搭建一个SpringCloud项目，从0到1搭建一个SpringClo

准备工作

JDK 版本17
MAVEN 版本3.9.8
idea 版本2023.3.4
Apifox 用来接口测试
spring-cloud-alibaba.version 2022.0.0.0-RC2
spring-cloud.version 2022.0.0
spring-boot.version 3.0.2

创建父项目

idea配置好maven和jdk后，new - project

创建子工程

删除父工程下的src文件夹，new - module

//pom.xml

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

</project>

因为父项目中的pom.xml中指定dependencyManagement标签来管理，子项目就不用写版本号了

//base-server application.properties文件配置
spring.application.name=base-server
server.port=8080

测试

新建OrgController.java

package org.base.baseserver.controller;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping(value = "/org")
public class OrgController {

    @GetMapping(value = "/test")
    public String test(){
        return "测试";
    }
}

启动项目，打开Apifoxc测试接口

测试成功

一个简单的SpringCloud项目就搭建好了
