dubbo+zookeeper整合springBoot

dubbo+zookeeper整合springBoot

1、zookeeper和dubbo-admin的下載和安裝請查看我上一篇文章：dubbo+zookeeper環境搭建

附：創建springBoot項目創建過程

2、項目結構


3、Consumer代碼明細
1）配置文件
pom.xm

<dependency>
	<groupId>com.alibaba.boot</groupId>
	<artifactId>dubbo-spring-boot-starter</artifactId>
	<!--<version>0.2.1.RELEASE</version>-->
	<version>0.2.0</version>
</dependency>
<dependency>
	<groupId>com.qing.zhao.dubbo</groupId>
	<artifactId>interface</artifactId>
	<version>1.0-SNAPSHOT</version>
</dependency>

application.properties

dubbo.application.name=dubbo-springBoot-consumer
dubbo.registry.protocol=zookeeper
dubbo.registry.address=127.0.0.1:2181
server.port=8010

2)業務代碼
ConsumerController.java

package com.qing.zhao.dubbo.controller;

import com.qing.zhao.dubbo.service.IConsumerService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;

@RequestMapping("/hello")
@Controller
public class ConsumerController {
    @Autowired
    private IConsumerService consumerService;

    @RequestMapping("/sayHello")
    @ResponseBody
    public String sayHello(@RequestParam("str") String params){
        return consumerService.sayHello(params);
    }
}

ConsumerServiceImpl.java

package com.qing.zhao.dubbo.impl;


import com.alibaba.dubbo.config.annotation.Reference;
import com.qing.zhao.dubbo.service.IConsumerService;
import com.qing.zhao.dubbo.service.IProducerService;
import org.springframework.stereotype.Service;

@Service
public class ConsumerServiceImpl implements IConsumerService {

    @Reference//dubbo的標籤，表示引用服務的提供者
    IProducerService producerService;
    
    @Override
    public String sayHello(String params) {

        return producerService.sayHello(params);
    }

    @Override
    public String sayHi() {
        return null;
    }
}

ConsumerApplication.java(啓動類)

package com.qing.zhao.dubbo;

import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@EnableDubbo//支持dubbo
@SpringBootApplication
public class ConsumerApplication {

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

}

4、Producer代碼明細

1）配置文件
pom.xml和Consumer的pom.xml配置文件一樣，同上

application.properties

dubbo.application.name=dubbo-springBoot-producer
dubbo.registry.protocol=zookeeper
dubbo.registry.address=127.0.0.1:2181
dubbo.protocol.name=dubbo
dubbo.protocol.port=20880
server.port=8089

2)邏輯代碼
ProducerServiceImpl.java

package com.qing.zhao.dubbo.impl;

import com.alibaba.dubbo.config.annotation.Service;
import com.qing.zhao.dubbo.service.IProducerService;
import org.springframework.stereotype.Component;

@Service
@Component
public class ProducerServiceImpl implements IProducerService {


    @Override
    public String sayHello(String name) {
        return "Hello:"+name;
    }
}

SpringBootProducerApplication.java(啓動類)

package com.qing.zhao.dubbo;

import com.alibaba.dubbo.config.spring.context.annotation.EnableDubbo;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@EnableDubbo
@SpringBootApplication
public class SpringBootProducerApplication {

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

}

5、Interface項目代碼同上篇文章一致，請查看其中Interface代碼
dubbo+zookeeper環境搭建

結果
啓動消費者和提供者後，自動將信息註冊到zookeeper上，通過dubbo Admin管理平臺就能查看到對應的服務


並能成功從消費方服務訪問到提供方服務的內容

dubbo成功將RPC過程封裝了
