本文详细介绍了如何使用Spring Boot和Dubbo搭建微服务架构，包括创建父项目、提供者、消费者及API模块，实现服务的注册、发现与调用。通过具体代码示例，展示了项目依赖管理、接口定义、服务实现与启动配置。

1.项目架构
在项里插入图片描述

1.创建一个公共要用的父项目（公用的依赖，其子项目就不需要在此引入依赖）
我此处创建的是父项目名称是: common

pom.xml

<?xml version="1.0" encoding="UTF-8"?>

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

</project>

2.provide（提供者）

pom.xml(只需表明父项目以及添加web依赖)

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
    <modelVersion>4.0.0</modelVersion>
    <parent>
   			
        <groupId>com.feng.common</groupId>
        <artifactId>common</artifactId>
        <version>0.0.1-SNAPSHOT</version>
    </parent>
    <groupId>com.feng.provider</groupId>
    <artifactId>provider</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <name>provider</name>
    <description>Demo project for Spring Boot</description>


    <properties>
        <java.version>1.8</java.version>
    </properties>

    <dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
    </dependencies>

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

项目架构
UserSservice:

package com.feng.dubbo.service;

public interface UserService {
    public String getProvide();
}

UserServiceImpl

package com.feng.dubbo.service.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.feng.dubbo.service.UserService;

//注册到zoockker上去
@Service
@org.springframework.stereotype.Service
public class UserServiceImpl implements UserService {
    @Override
    public String getProvide() {
        return "我是提供者";
    }
}

application.yml

spring:
  dubbo:
    appname: provider
    registry: zookeeper://192.168.130.128:2181
    protocol: dubbo
    port: 20880
server:
  port: 8081

CustomApplication.java（启动类）

package com.feng.dubbo;

import com.alibaba.dubbo.spring.boot.annotation.EnableDubboConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication
//启动dubbo配置
@EnableDubboConfiguration
public class CustomApplication {

    public static void main(String[] args) {
        SpringApplication.run(CustomApplication.class, args);
    }

}

3.custom（consumer消费者，我这里英文打错）

pom.xml文件什么都不需要
src/main目录结构只需与provide的接口一致即可其它都不需要

4.myapi
pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">

            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
        <!--引入消费者custom这个项目-->
        <dependency>
            <groupId>com.feng.custom</groupId>
            <artifactId>custom</artifactId>
            <version>0.0.1-SNAPSHOT</version>
        </dependency>

    </dependencies>

        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

</project>

项目架构
application.ynl

spring:
  dubbo:
    appname: consumer
    registry: zookeeper://192.168.130.128:2181
    protocol: dubbo
    port: 20880
server:
  port: 8888

MyapiApplication.java(启动类)

package com.feng.dubbo.myapi;

import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import com.alibaba.dubbo.spring.boot.annotation.EnableDubboConfiguration;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
@SpringBootApplication
//启动dubbo配置
@EnableDubboConfiguration
public class MyapiApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyapiApplication.class, args);
    }

}

UserController

package com.feng.dubbo.myapi.controller;


import com.alibaba.dubbo.config.annotation.Reference;
import com.feng.dubbo.service.UserService;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

import java.net.URI;

@RestController
public class UserController {
    @Reference  //com.alibaba.dubbo.config.annotation.Reference; 不要导错
    UserService userService;    //相当于是provide的service了

    @RequestMapping("/test")
    public String testDubbo() {
        return  userService.getProvide();   
    }

}
