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
- 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。
4.0.0 com.sxh dubbo-nacos 1.0-SNAPSHOT common-api dubbo-provide service-consumer pom dubbo-nacos Maven Webapp http://www.example.com UTF-8 8 8 4.1.56.Final 2.3.5.RELEASE 2.7.8 1.4.0 org.springframework.boot spring-boot-dependencies ${spring-boot.version} pom import org.apache.dubbo dubbo-dependencies-bom ${dubbo.version} pom import org.apache.dubbo dubbo-spring-boot-starter ${dubbo.version} org.apache.dubbo dubbo-registry-nacos ${dubbo.version} com.alibaba.nacos nacos-client ${nacos-client.version} org.apache.dubbo dubbo ${dubbo.version} org.springframework spring javax.servlet servlet-api log4j log4j org.springframework.boot spring-boot-starter-test test junit junit 4.11 test dubbo-nacos maven-clean-plugin 3.1.0 maven-resources-plugin 3.0.2 maven-compiler-plugin 3.8.0 maven-surefire-plugin 2.22.1 maven-war-plugin 3.2.2 maven-install-plugin 2.5.2 maven-deploy-plugin 2.8.2
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
4.0.0 com.sxh dubbo-nacos 1.0-SNAPSHOT com.sxh common-api 1.0-SNAPSHOT war common-api Maven Webapp http://www.example.com UTF-8 1.7 1.7 junit junit 4.11 test common-api maven-clean-plugin 3.1.0 maven-resources-plugin 3.0.2 maven-compiler-plugin 3.8.0 maven-surefire-plugin 2.22.1 maven-war-plugin 3.2.2 maven-install-plugin 2.5.2 maven-deploy-plugin 2.8.2
创建SayService:
package com.sxh.service;
public interface SayService {
String sayHelloByName(String name);
}
dubbo-provide：
pom.xml
com.sxh dubbo-nacos 1.0-SNAPSHOT 4.0.0 com.sxh dubbo-provide 0.0.1-SNAPSHOT dubbo-provide dubbo-provide 1.8 UTF-8 UTF-8 2.3.7.RELEASE org.springframework.boot spring-boot-starter-web org.apache.dubbo dubbo-spring-boot-starter org.apache.dubbo dubbo org.apache.dubbo dubbo-registry-nacos com.alibaba.nacos nacos-client com.sxh common-api 1.0-SNAPSHOT org.springframework.boot spring-boot-test 2.5.4 test org.junit.jupiter junit-jupiter test org.springframework.boot spring-boot-dependencies ${spring-boot.version} pom import org.apache.maven.plugins maven-compiler-plugin 3.8.1 1.8 1.8 UTF-8 org.springframework.boot spring-boot-maven-plugin 2.3.7.RELEASE com.sxh.dubboprovide.DubboProvideApplication repackage repackage
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
application.yml:`

port: 14511
spring:
application:

main:
allow-bean-definition-overriding: true
dubbo:

dubbo-consumer
pom.xml:

application.yml:
跟上面一样，改成自己的ip
server:

spring:
application:

main:
allow-bean-definition-overriding: true
dubbo:
application:

registry:

username: nacos

protocol:

port: 15511
SayController.java:
package com.sxh.serviceconsumer.controller;
import com.sxh.service.SayService;
import org.apache.dubbo.config.annotation.DubboReference;
import org.springframework.http.ResponseEntity;
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.RestController;
@RestController
@RequestMapping("/demo/say")
public class SayController {
@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
