SpringBoot整合dubbo3.0+nacos2.0以及zookeeper
springboot2.6 + dubbo 3.0 + nacos 2.0和zookeeper ，nacos和zookeeper依赖都引入了,想用哪个都可以
1.项目结构
sg-app:消费者
sg-com-api:公共接口 (消费者和提供者需要引用)
sg-com-tool:公共工具包 (提供时间转换,字符串转换等工具转换类) 不详写也可以不加
sg-web-parent:父依赖包 (消费者和提供者需要继承) 用于管理依赖
sg-web-provider:提供者
1.创建父模块 sg-web-parent
注：父类只用于管理依赖，处理多个消费者和提供者的情况,所以只有pom

接口发布
package cn.xwl.dubbo.login.service;
import cn.sg.user.LoginService;
import org.apache.dubbo.config.annotation.DubboService;
@DubboService
public class LoginServiceImpl implements LoginService {
public String baseLogin(String username, String password) {
if("123".equals(password)){
return "登录成功！欢迎你"+username;
}
return "登陆失败,请检查密码是否正确";
}
}
在yml中配置dubbo.scan.base-packages为扫描路径，与spring扫描类似，在扫描到的路径下创建需要发布的接口 并添加@DubboService,服务就i会自动发布到nacos中
3.服务消费者配置

yml
server:
port: 7070
dubbo:
application: #当前这个应用的信息
name: sg-web-consumer #应用名
registry: #注册相关信息
#address: zookeeper://10.250.204.106:2181 #注册中心配置
address: nacos://10.250.200.103:8848 #注册中心配置
timeout: 30000 # 到注册中心的超时时间
consumer:
timeout: 50000 # 访问服务超时时间
服务实现接口：
package web.login;
import cn.sg.user.LoginService;
import org.apache.dubbo.config.annotation.DubboReference;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class loginController {
@DubboReference
public LoginService loginService;
@RequestMapping("baseLogin")
public String baseLogin(String username,String password){
return loginService.baseLogin(username,password);
}
}
服务实现接口只需要直接使用@DubboReference 引用接口类就能够直接远程调用了，前提是消费者和提供者都引用了公共接口包。
4.公共接口包sg-com-api
package cn.sg.user;
//登录接口服务定义
public interface LoginService {
//普通登录接口 通过用户名密码登录
String baseLogin(String username,String password);
}
只定义接口和实体类
运行结果
访问http://localhost:7070/baseLogin?username=xwl&password=123
