springboot?集成dubbo的步驟詳解

 更新時(shí)間:2022年04月08日 11:40:19   作者:m0_54861649  
這篇文章主要介紹了springboot?簡(jiǎn)易集成dubbo的步驟詳解,本文結(jié)合示例代碼給大家介紹的非常詳細(xì),對(duì)大家的學(xué)習(xí)或工作具有一定的參考借鑒價(jià)值,需要的朋友可以參考下

寫在前面:在閱讀本文前,請(qǐng)前擁有dubbo基礎(chǔ)知識(shí),springboot知識(shí)

dubbo官網(wǎng): http://dubbo.apache.org
dubbo github 源碼地址:https://github.com/apache/incubator-dubbo
dubbo 運(yùn)維項(xiàng)目源碼地址:https://github.com/apache/incubator-dubbo-ops

本文項(xiàng)目GitHub: https://github.com/Blankwhiter/dubbo-spring-boot-starter-test
源碼對(duì)應(yīng)版本1.0.1: https://github.com/Blankwhiter/dubbo-spring-boot-starter-test/archive/1.0.1.zip

第一步 搭建zookeeper環(huán)境

在centos窗口中,執(zhí)行如下命令,拉取鏡像,并啟動(dòng)zookeeper容器

docker pull zookeeper
docker run -d -v /home/docker/zookeeperhost/zookeeperDataDir:/data -v /home/docker/zookeeperhost/zookeeperDataLogDir:/datalog  -e ZOO_MY_ID=1 -e ZOO_SERVERS='server.1=125.77.116.145:2888:3888'  -p 2182:2181 -p 2888:2888 -p 3888:3888  --name zookeeper --privileged zookeeper

注:

1.zookeeper默認(rèn)連接端口是2181 但本文測(cè)試用例時(shí)由于被其他程序占走,故使用2182。

2.讀者請(qǐng)自行創(chuàng)建映射目錄zookeeperDataDir | zookeeperDataLogDir

第二步 springboot集成dubbo

1.項(xiàng)目目錄機(jī)構(gòu)

在這里插入圖片描述

說(shuō)明:

  • 1.api目錄:存放消費(fèi)者與提供者調(diào)用的service接口
  • 2.consumer目錄:消費(fèi)者目錄 調(diào)用提供者遠(yuǎn)程提供的接口實(shí)現(xiàn)
  • 3.provider目錄:提供者目錄 提供給消費(fèi)者接口實(shí)現(xiàn)

讀者請(qǐng)自行創(chuàng)建項(xiàng)目目錄(創(chuàng)建空項(xiàng)目,然后在空項(xiàng)目中新建三個(gè)module)

項(xiàng)目案例說(shuō)明:業(yè)務(wù)假設(shè)場(chǎng)景=》 產(chǎn)品購(gòu)買消費(fèi)金額(consumer)同時(shí)并返回所有消費(fèi)的總金額(需要調(diào)用到provider項(xiàng)目中服務(wù)實(shí)現(xiàn))。

2.代碼編寫

2.1 api目錄

接口編寫

2.1.1.在com.dubbo.api.service(讀者請(qǐng)自行創(chuàng)建,下同,package創(chuàng)建將不一一贅述)包下創(chuàng)建CostService.java

package com.dubbo.api.service;

public interface CostService {
    /**
     * 成本增加接口
     * @param cost
     * @return
     */
    Integer add(int cost);
}

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


</project>

2.2.3.使用 @EnableDubbo 注解開啟dubbo
ConsumerApplication.java 啟動(dòng)類

package com.dubbo.consumer;
import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableDubbo
public class ConsumerApplication {

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

2.2.4.編寫產(chǎn)品service接口 ProductService.java

package com.dubbo.consumer.service;
public interface ProductService {
    /**
     * 獲得總消費(fèi)
     * @param a
     * @return
     */
    Integer getCost(int a);
}

2.2.5.編寫產(chǎn)品接口的實(shí)現(xiàn),并調(diào)用遠(yuǎn)程服務(wù)CostService 。 ProductServiceImpl.java

package com.dubbo.consumer.service.impl;
import com.alibaba.dubbo.config.annotation.Reference;
import com.dubbo.api.service.CostService;
import com.dubbo.consumer.service.ProductService;
import org.springframework.stereotype.Service;
/**
 * 產(chǎn)品service
 */
@Service
public class ProductServiceImpl implements ProductService {
    /**
     * 使用dubbo的注解 com.alibaba.dubbo.config.annotation.Reference。進(jìn)行遠(yuǎn)程調(diào)用service
     */
    @Reference
    private CostService costService;
    @Override
    public Integer getCost(int a) {
        return costService.add(a);
    }
}

2.2.6.編寫訪問類,ProductController.java

package com.dubbo.consumer.controller;
import com.dubbo.consumer.service.ProductService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
/**
 * 產(chǎn)品controller
 */
@RestController
public class ProductController {
    @Autowired
    private ProductService productService;
    /**
     * 添加完 返回總共消費(fèi)
     * @param a
     * @return
     */
    @RequestMapping("/add")
    public String getCost(int a){
        return "該產(chǎn)品總共消費(fèi) :"+productService.getCost(a);
    }
}

2.3 provider目錄 api接口實(shí)現(xiàn)以及dubbo配置

2.3.1.引入 dubbo-spring-boot-starter 以及 上述的api模塊

<?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">

            <artifactId>spring-boot-starter-test</artifactId>
            <scope>test</scope>
        <!--引入api-->
            <groupId>com.dubbo</groupId>
            <artifactId>api</artifactId>
            <version>0.0.1-SNAPSHOT</version>
            <scope>compile</scope>
        <!--引入dubbo環(huán)境-->
            <groupId>com.alibaba.boot</groupId>
            <artifactId>dubbo-spring-boot-starter</artifactId>
            <version>0.2.0</version>

                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>
</project>

2.3.2.在resources目錄下 創(chuàng)建application.yml,并編寫dubbo配置

dubbo:
  application:
    name: dubbo-provider
  registry:
    address: 125.77.116.145:2182
    # 讀者請(qǐng)自行更改zookeeper地址
    protocol: zookeeper
    check: false
  protocol:
    name: dubbo
    port: 30003
  monitor:
    protocol: register
  consumer:
    check: false
    timeout: 3000

server:
  port: 8061

2.3.3.使用 @EnableDubbo 注解開啟dubbo
ConsumerApplication.java 啟動(dòng)類

package com.dubbo.provider;
import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
@EnableDubbo
public class ProviderApplication {

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

2.3.3.編寫CostService服務(wù)實(shí)現(xiàn) CostServiceImpl.java

package com.dubbo.provider.service.impl;
import com.alibaba.dubbo.config.annotation.Service;
import com.dubbo.api.service.CostService;
/**
 * 花費(fèi)服務(wù)
 */
@Service
public class CostServiceImpl implements CostService {
    /**
     * 假設(shè)之前總花費(fèi)了100
     */
    private final Integer totalCost = 1000;
    /**
     * 之前總和 加上 最近一筆
     * @param cost
     * @return
     */
    @Override
    public Integer add(int cost) {
        return totalCost + cost;
    }
}

第三步 測(cè)試dubbo遠(yuǎn)程服務(wù)調(diào)用

編寫第二步代碼完成后 ,啟動(dòng)consumer項(xiàng)目,以及provider項(xiàng)目
在瀏覽器中訪問 http://localhost:8062/add?a=100

在這里插入圖片描述

出現(xiàn)如上結(jié)果即為調(diào)用成功

第四步 dubbo管理平臺(tái)

dubbo運(yùn)維舊版地址: https://github.com/apache/incubator-dubbo-ops/tree/master

1.本文將運(yùn)維項(xiàng)目代碼下載放于 D:learnplaceincubator-dubbo-ops

2.這里需要修改一個(gè)配置D:learnplaceincubator-dubbo-opsdubbo-adminsrcmain esourcesapplication.properties

3.在D:learnplaceincubator-dubbo-opsdubbo-admin目錄下 ,進(jìn)入cmd窗口執(zhí)行
mvn claen package 打包項(xiàng)目,
4.然后進(jìn)入D:learnplaceincubator-dubbo-opsdubbo-admin arget ,進(jìn)入cmd窗口執(zhí)行
java -jar dubbo-admin-0.0.1-SNAPSHOT.jar 運(yùn)行項(xiàng)目
5.啟動(dòng)成功后 瀏覽器訪問http://localhost:8001 輸入賬號(hào):root / 密碼:root 即可。
