Spring Boot和Dubbo整合

provider端

1. POM依赖

<dependencies>

	<dependency>

		<groupId>org.springframework.boot</groupId>

		<artifactId>spring-boot-starter-web</artifactId>

	</dependency>

	<dependency>

		<groupId>org.projectlombok</groupId>

	<!--dubbo-->

1. service实现

package com.lovefly.pms.services.service;

import com.alibaba.dubbo.config.annotation.Service;

import com.lovefly.pms.interfaces.service.TestService;

@Service

public class TestServiceImpl implements TestService {

    @Override

    public String echo(String input) {

        return input + ": pong from service";

    }

}

1. application.properties

#server

server.port=8001

#dubbo

spring.dubbo.registry.group=pms

spring.dubbo.application.name=pms-services

spring.dubbo.registry.address=zookeeper://127.0.0.1:2181

1. consumer实现

package com.lovefly.pms.portal.controller;

import com.alibaba.dubbo.config.annotation.Reference;

import com.lovefly.pms.interfaces.service.TestService;

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("/api/echo")

public class EchoController {

    @Reference

    private TestService echoService;

    @GetMapping("")

    public String echo(@RequestParam("input") String input){

        String pong = echoService.echo(input);

        return pong;

    }

}

1. application.properties

#server

server.port=8000

#dubbo

spring.dubbo.registry.group=pms

spring.dubbo.application.name=pms-portal

spring.dubbo.protocol.name=dubbo

spring.dubbo.protocol.port=20880

spring.dubbo.registry.address=zookeeper://127.0.0.1:2181

spring.dubbo.scan=com.lovefly.pms.portal

spring.dubbo.consumer.retries=0

spring.dubbo.consumer.timeout=30000

spring.dubbo.consumer.check=false

1. 测试

• 启动zookeeper
• 使用curl或PostMan测试服务调用

curl -X GET http://localhost:8000/api/echo/?input=test

#输出：

test: pong from service

将目录添加到github项目中

1. 进入工作目录
2. 执行以下命令

$ mvn clean

$ git init

$ git add remote origin https://github.com/fuhongwei041/lovefly-pms.git

$ git branch --set-upstream-to=origin/master master

$ git pull origin master

$ # 编辑.gitignore文件

$ git add .

$ git commit -m "first commit"

项目地址为https://github.com/fuhongwei041/lovefly-pms.git
