idea+springboot+nacos+dubbo 多模块项目搭建 超详细

有一个很简单的不用配置pom和dependecy的方法，但是每个模块不是工程，https://blog.csdn.net/qq_43762185/article/details/120811212?spm=1001.2014.3001.5501
我也是参考了很多博主，其中主要是这个博主的
https://cloud.tencent.com/developer/article/1837815
我会描述的更详细一点

正文

1. nacos下载及配置

1.1进入官网https://github.com/alibaba/nacos/releases
将页面滑倒最下面，可以看到，一般win系统下载zip，然后解压

1.2.
如果你是在跟我一样练手，cmd cd到bin目录，输入以下语句 单机模式启动
startup.cmd -m standalone
如果你是集群启动，就可以直接在bin目录下双击stratup.cmd
1.3启动成功后，输入红框中的地址，默认账号和密码是nacos

2.springboot项目搭建(重点)
2.1创建一个一个maven项目


创建好以后，删除src目录，配置pom文件，下面是我的pom文件
这里有几个注意点：
你前面的groupid是什么，你这里就要是什么，我的就是com.sxh
你粘贴上去可能会报错，因为还没有创建modules，之后创建了就好了，这是父工程。

2.2在父工程下面创建三个子工程，分别为commn-api（maven工程），dubbo-service（springboot工程），service-consumer（springboot工程），这是整体的目录

创建好了之后，对于common-api
pom.xml
主要加入parent模块和一些依赖

SayServiceImpl.java:
出现红线不要慌，看能不能import class,要不然就加入依赖，刷新一下maven

package com.sxh.dubboprovide.impl;

import com.sxh.service.SayService;
import org.apache.dubbo.config.annotation.DubboService;

@DubboService
public class SayServiceImpl implements SayService {
    @Override
    public String sayHelloByName(String name) {
        return name+",hello!";
    }
}

启动类上加上@EnableDubbo注解

    @DubboReference
    private SayService sayService;

    @GetMapping("/sayHello")
    public ResponseEntity sayHello(@RequestParam("name") String name) {
        return ResponseEntity.ok(sayService.sayHelloByName(name));
    }
}

启动类上也要加上@EnableDubbo
2.3依次启动provider，consumer模块，就可以看到

2.4测试接口
